Commercial Painting Costs in South Australia

Commercial painting across South Australia generally costs $14 to $32 per square metre for interior wall repaints, $9 to $22 per square metre for sprayed warehouse interiors, $20 to $55 per square metre for industrial and factory exteriors, and $45 to $140 per square metre for structural steel carrying a protective coating system. A small suburban office suite of under 200 square metres usually lands between $3,500 and $9,500. Those ranges look wide because they describe different work rather than the same work priced differently. The variable doing most of the damage is the condition of what you are painting over, and that is assessed on site rather than from a floor plan. The expensive mistake in commercial painting is rarely overpaying. It is accepting a price built on an optimistic view of preparation, watching the finish fail inside two or three years, and paying a second time for the same wall while the building carries the disruption twice.

Preparation is where quotes diverge and it is also where they are least specific. One contractor allows for a wash down, spot filling and a bonding primer over a chalked substrate. Another allows for two coats over whatever is there. Both quotes say the building will be painted, both are technically accurate, and only one of them will still look right at the end of the warranty period. Reading the preparation clause is more useful than reading the total, because that is the clause the total is built on.

If a quote does not have a preparation clause at all, you have not been given a scope, you have been given a number. South Australia adds a second layer that other states do not carry to the same degree, because so much of the commercial building stock in Adelaide and the older regional towns is porous masonry of a kind that reacts badly to the wrong coating. Bluestone, sandstone, limestone and soft early brick move moisture through their surfaces by design, and sealing that surface with a modern impermeable film can push the problem inward instead of stopping it. Combined with heritage listings that restrict what may be painted at all, this makes the specification question more consequential here than the price question.

This page covers what commercial work involves, the licence a contractor is required to hold, the Australian Standards that sit behind a proper specification, the preparation question in detail, heritage and salt damp, corrosion in coastal and industrial locations, lead and asbestos on older buildings, occupied premises, strata and community title, and what to establish before you sign anything. Broader background on the trade sits in the SA painters guide. The pricing sections toward the end separate metropolitan Adelaide from regional South Australia because the gap is real and it is driven by travel and availability rather than by skill. Ask for that to appear on the written scope.

What Commercial Painting Covers

Commercial painting is a broader category than most people expect and the businesses within it are not interchangeable. At one end sits ordinary interior and exterior decorative work on offices, shops, schools, clubs and medical suites, which is close to domestic painting done at scale and to a commercial program. At the other end sits protective coating of steel, concrete and plant, which is a different discipline entirely with its own standards, inspection regime and qualifications. A crew that produces beautiful office walls may have no experience with a zinc primer, and a crew that coats bridge steel may not be the right choice for a boutique fitout on Rundle Street. Asking which end of that spectrum a contractor actually works in is a fair opening question.

Decorative commercial work usually means walls, ceilings, doors, frames, trim, service cupboards and back of house areas, applied by brush, roller or airless spray depending on the space. Programs are built around the building's operating hours rather than around the painter's convenience. Colour matching to a tenancy schedule or a brand standard is normal, as is working to a defects list at handover. Most operators will confirm it if asked directly.

Industrial and protective work covers structural steel, roof sheeting, tanks, silos, plant, walkways and handrails, and it is specified by system rather than by product. A specification names the surface preparation grade, each coat in sequence, the dry film thickness required for each, and the total system thickness. Verification happens on site with gauges and recorded, which is why this work carries an inspection cost that decorative work does not. Anyone quoting protective work without reference to a system is quoting something else.

A number of adjacent services get lumped in with commercial painting and it helps to know they are separate line items rather than assumptions. Epoxy floor coating for warehouses and workshops, texture coating over render, roof coating on factory sheeting, line marking in car parks and warehouse aisles, and anti-graffiti systems on street-facing walls are each priced independently. Bundling them with one contractor often saves on mobilisation. Assuming they are included because they were mentioned in a meeting does not.

Fitout and refurbishment work sits somewhere between the two and carries a scheduling burden all of its own. On a live fitout the painter is one trade among many, the walls are not ready when the program says they will be, and the finishing coats have to happen after the ceiling grid, the electrical fitoff and the joinery, which in practice means the painter is asked to do a two week job in four nights at the end. Sequencing should be discussed before the program is set, because a painter who is consulted early will tell you where the plan is unrealistic. One who is handed the program at the last minute simply prices the risk into the rate. Both outcomes cost money, but only one of them produces a good finish. Commercial plastering normally precedes the painter and the quality of that handover directly affects the paint result.

Licensing and Who Can Do the Work

Painting and decorating is defined as building work in South Australia, and anyone who contracts to carry it out for others must hold a building work contractor's licence issued by Consumer and Business Services. The licence can be limited to painting and decorating rather than covering general building work, and there is no dollar threshold below which the requirement falls away. This is not a formality and it is not universal across Australia, since the rules and thresholds differ from state to state. Checking the licence before engaging anyone takes about a minute on the public register, and the register is the authoritative source not a logo on a quote.

Licence details are published by Consumer and Business Services. There is a distinction here that catches commercial clients out repeatedly, and you should understand it before relying on protections you may have heard about. The statutory warranties, the mandatory written contract requirements and the building indemnity insurance obligations under South Australian building work legislation attach to domestic building work rather than to commercial contracts. If your previous experience of engaging a painter was a home renovation, the safety net you had then does not automatically extend to your business premises. What protects you on a commercial job is the contract you sign and the general law, which puts the burden back on the document.

That makes the contract itself deserve more attention than it usually gets. A commercial painting contract should identify the scope by area and surface, name the coating system, state the preparation standard, set out the program and any access requirements, deal with variations and how they are approved, and specify the defects liability period and what it covers. Payment terms and retention, if any, belong in the same document. It is worth settling before the deposit rather than after.

Insurance is the other item to verify instead of assuming. Public liability cover is standard and the certificate of currency should be sighted not just described, with the sum insured checked against what your site actually requires, since many commercial landlords and shopping centres set their own minimums as a condition of site access. Workers compensation cover for employees is a legal obligation in South Australia and its absence is a serious warning sign. If the contractor engages subcontract crews, ask how those crews are covered, because the answer is not always what the head contractor assumes.

Trade qualification sits underneath the licence and is a separate question. The recognised pathway is a Certificate III in Painting and Decorating completed through an apprenticeship, and on larger commercial and industrial jobs you will also encounter coating inspectors holding independent certification for verifying protective systems. Neither guarantees a good outcome on its own, but a contractor who can tell you who on the crew is qualified, who is an apprentice and who supervises them is a contractor who runs an organised business. A site inspection answers it faster than a phone call.

For public sector work in South Australia there is an additional layer. The state government operates a prequalification system for building and construction contractors, and contractors seeking government work are generally required to be prequalified at a level suitable to the value and complexity of the contract. If your project involves a school, a health facility or another government asset, prequalification status is a real screening criterion rather than a nicety. Private clients sometimes use it as an informal quality filter too, on the reasoning that a contractor already assessed for government work has demonstrated systems, financial capacity and safety documentation to somebody else's satisfaction.

The Standards Behind the Work

Two Australian Standards do most of the work in commercial painting and knowing their names changes how you read a quote. AS/NZS 2311, the guide to the painting of buildings, covers surface preparation, coating selection and application for building work, and it is the document a competent painter is working to whether or not they mention it AS/NZS 2312 covers protection of structural steel against atmospheric corrosion, with Part 1 dealing with paint coatings and Part 2 with hot dip galvanizing, and it is the document that governs anything structural A quote for industrial steel that references neither is not a specification. Standards are published and maintained by Standards Australia. AS 4312 is the third one to know because it sets out atmospheric corrosivity categories across Australia, running from C1 in dry sheltered interiors through to C5 in severe marine and industrial environments. Those categories feed directly into what AS/NZS 2312 requires, so the corrosivity of your site determines the coating system rather than the other way around. This is why a specification written for an inland warehouse cannot simply be reused on a coastal one.

On protective work, AS 3894 governs site testing of applied coatings. It covers dry film thickness measurement, adhesion testing and holiday detection, which is the process of finding pinholes and discontinuities in a coating that would otherwise let moisture reach the substrate. Where a job carries an inspection and test plan, this is the standard behind it, and the records produced become the evidence that the system was actually applied as specified rather than merely quoted. On any significant industrial contract insist on those records.

Two further standards affect commercial buildings in ways that surprise people. AS 1428.1, the access and mobility standard, sets luminance contrast requirements, luminance contrast being the difference in the amount of light two adjacent surfaces reflect, between certain building elements, commonly expressed as a minimum of 30 per cent between a door leaf, its frame and the adjacent wall, or between a glazing band and its background. That is a paint decision as much as an architectural one, and a colour scheme chosen purely on appearance can put a commercial fitout out of compliance. Where accessibility compliance is part of your project, the colour schedule needs checking against it rather than assuming the painter will raise it.

The other is fire performance. The National Construction Code sets fire hazard property requirements for wall and ceiling linings in commercial building classes, and coatings applied to those surfaces can affect compliance, with thin paint films over non-combustible substrates generally treated differently from thick decorative or textured systems. Intumescent coatings sit in a separate category again, since they are applied to structural steel specifically to achieve a fire resistance level and their thickness is calculated for each member. That work is verified, documented and considerably more expensive than ordinary painting, commonly in the region of $60 to $180 per square metre depending on the resistance level required. It is not a job for a general commercial crew.

Environmental performance now appears in commercial specifications routinely. Green Star and similar rating schemes set maximum volatile organic compound limits for interior paints, commonly around 16 grams per litre for flat wall finishes with higher allowances for enamels and trim, and the applicable limits depend on which version of the scheme your project is certified under. If your building is chasing a rating, the paint schedule must be checked against the credit rather than against a marketing claim on the tin. That single detail separates two otherwise similar quotes.

Preparation and Why It Decides Everything

Coating failure in commercial buildings is overwhelmingly an adhesion problem rather than a product problem. Paint applied over a chalked, dirty, damp or unstable surface will separate from that surface regardless of what it cost per litre, and the failure shows up between eighteen months and four years later as flaking, peeling or blistering across whole panels rather than in isolated spots. The product carries the blame and the preparation caused it. Which is why the preparation line is the one worth reading closely in any commercial quote.

On previously painted commercial exteriors the standard sequence is assessment, cleaning, repair, stabilising and priming, and each of those steps is a cost. Assessment establishes what the existing coating is and whether it is sound, usually by adhesion testing at a few representative points. Cleaning removes chalk, dirt, salt, mould and any surface contamination, which on a coastal building means a fresh water wash not just a pressure clean, because pressure alone drives salts in rather than removing them. Repair addresses cracks, spalled render and failed sealant. Stabilising binds any remaining chalk with a penetrating primer. Only then does a finish coat make sense.

Adelaide's reactive clay soils give this a local dimension that matters on commercial buildings as much as on houses. Movement in the Adelaide Plains clays opens hairline and structural cracks in rendered and masonry walls seasonally, and a rigid filler in a moving crack will simply reopen, often within the first summer. Flexible sealants and elastomeric bridging systems exist for exactly this and cost more per metre than a standard filler. Where a building has visible stepped cracking rather than surface crazing, the honest advice is to establish the cause before painting, because paint over a structural problem is money spent concealing evidence. Render repair is normally a separate trade and separate cost from the painting.

On new commercial substrates the issues are different. New render and concrete carry high alkalinity and need adequate curing time before coating, several weeks not days, and applying a finish too early causes saponification, which shows up as a soft sticky film or patchy gloss. New plasterboard needs a sealer designed for the purpose so that the paper face and the jointing compound absorb evenly, otherwise joints ghost through under raking light in a way that is very difficult to correct afterwards. Galvanized steel and Colorbond need a specific etch or bonding primer not a general one. Each of these is basic knowledge for a commercial painter and each of them is skipped occasionally under program pressure.

Dust and abrasive processes bring a health obligation into preparation. Sanding render, concrete or masonry generates respirable crystalline silica, meaning dust particles fine enough to reach deep into the lungs, and dry sanding of old paint films generates whatever was in those films. On commercial sites this drives dust extraction, wet methods, exclusion zones and respiratory protection, all of which appear in the price. A contractor who proposes dry mechanical sanding of a 1950s rendered facade without controls is telling you something about how they operate.

The practical way to compare quotes on preparation is to make the scope explicit before you request them. Specify that quotes must state the cleaning method, the repair allowance, the primer or sealer to be used and the number of finish coats, and that any preparation excluded must be listed. That single request converts a set of incomparable numbers into a set of comparable ones, and it usually reveals which contractor actually walked the building. Preparation and repair specialists can handle that stage separately where the substrate work is sizeable. Ask for that to be itemised on the scope.

Heritage Buildings and Approvals

South Australia carries an unusually high concentration of nineteenth and early twentieth century commercial buildings still in active use, and Adelaide's commercial strips are full of them. Hindley Street, Rundle Street East, King William Street, The Parade at Norwood, Jetty Road at Glenelg, Semaphore Road, Port Adelaide, and the main streets of Gawler, Strathalbyn, Burra, Kapunda and Mount Gambier are all built from stone and early brick A large proportion of those buildings carry either State Heritage Place status, Local Heritage Place status, or sit within a Historic Area or Character Area under the planning system. Painting decisions on those buildings are regulated. Establishing the listing position before design work starts avoids redoing it afterwards.

Planning in South Australia operates under the Planning, Development and Infrastructure Act and the Planning and Design Code, administered through the PlanSA system, and heritage provisions sit within that framework. The general position that matters most for painting is straightforward even though the detail is not: repainting a previously painted surface in a similar colour is commonly treated as maintenance and often needs no approval, while painting a previously unpainted masonry surface is generally development that requires consent and is frequently refused on heritage grounds. That distinction is the one to check first, because it is the one that produces enforcement action. General planning and heritage information for the state is published at sa.gov.au. Most commercial contractors will confirm it on request.

Getting this wrong is not a minor administrative issue. Unauthorised painting of heritage stonework can attract enforcement requiring removal of the coating, and removing paint from soft stone without damaging it is difficult, slow, expensive and sometimes not fully possible. The stone can be permanently altered in the attempt. Councils take enforcement on heritage stonework seriously, and reinstatement is far dearer than the original job.

Colour is also regulated in some circumstances, particularly within Historic Area Overlays where a council may have adopted a palette or where a previous consent imposed conditions. Tenants refitting a shopfront in these areas frequently discover the constraint after ordering signage. The sequence that avoids trouble is to confirm the heritage status of the building through the council or the PlanSA portal, establish whether the surfaces you intend to paint have been painted before, and obtain any required consent before the contractor mobilises. The check costs nothing and takes an afternoon.

On a listed building, the specification itself usually needs to change. Modern impermeable acrylic and plastic membrane coatings are widely unsuitable on historic masonry because they restrict moisture movement, and heritage practice generally favours vapour permeable systems, meaning coatings that let water vapour pass out through the wall, such as mineral silicate paints bound with potassium silicate or traditional lime based finishes that let the wall breathe. Those products cost more, require different application skills and are not stocked by every trade counter A contractor experienced with heritage painting will already know this and will say so unprompted, and that response is a useful test of whether you are talking to the right business. Heritage plaster restoration often runs alongside on interiors with original lath and lime work.

Salt Damp and Adelaide Masonry

Salt damp is the single most South Australian problem in this entire field and it deserves its own section because painting is so often the thing that makes it worse. It occurs where groundwater rises through porous masonry by capillary action, carrying dissolved salts with it, and as the water evaporates at the wall surface those salts crystallise and expand. The expansion breaks down mortar and the face of the stone or brick. Adelaide's older commercial stock is particularly exposed because so much of it predates effective damp proof courses, and where early courses of slate, lead or bitumen were installed, many have since cracked or been bridged.

The visible signs are consistent enough to recognise. A band of damage running roughly 300 millimetres to a metre above external ground level, white powdery efflorescence on the surface, mortar that crumbles when scraped, stone faces that fret and shed, and paint that blisters and peels in that same band while the wall above it looks fine. Internally it presents as tide marks, bubbling paint at skirting height and a musty smell in ground floor storerooms. Once you know the pattern it is hard to miss on Adelaide bluestone and sandstone.

The instinct is to paint over it and the instinct is wrong. Applying an impermeable coating to a wall carrying rising damp does not stop the moisture, it simply moves the evaporation point further into the masonry, so the salt crystallisation now happens behind the paint film instead of at the surface. The paint blisters off within a season or two and the stone underneath has continued to decay in the meantime, often faster than before because the moisture is no longer escaping. Sealers marketed as waterproofing can produce exactly this outcome on a wall that needed the opposite treatment.

The correct sequence deals with the cause first. That means identifying and addressing the source, which may involve installing or reinstating a damp proof course by chemical injection or physical means, reducing external ground and paving levels where they have risen above the original course, fixing leaking downpipes and stormwater, improving subfloor and ground level ventilation, and removing hard impermeable render that has been applied over the affected area. Salt contaminated render and mortar generally has to come off and be replaced with a permeable lime based mix. Only after the wall has been allowed to dry, which can take many months, does coating become sensible, and the coating chosen should be vapour permeable. Damp proofing specialists handle the remedial stage and subfloor ventilation often forms part of the solution.

For a commercial building owner the practical implication is a sequencing one. If your building shows salt damp and you have budgeted for a repaint, the repaint is not the job. The remedial work is the job and the repaint is the last stage of it, potentially a season later. Painters who understand South Australian masonry will tell you this at the inspection and decline to quote a straight repaint over an active damp problem. That refusal is a good sign rather than an inconvenience, and a quote that ignores obvious salt damp is a quote to do the same work again in two years.

Coastal and Industrial Corrosion

Corrosivity varies enormously across South Australia and the specification has to follow it. Airborne salt from Gulf St Vincent and Spencer Gulf drives higher corrosivity along the metropolitan coast, the LeFevre Peninsula, Semaphore, Outer Harbor, Port Adelaide, Glenelg and down the Fleurieu, with the severity falling away rapidly as you move inland. Industrial emissions add a second dimension around Whyalla, Port Pirie and Port Augusta. Under AS 4312 those environments sit in higher corrosivity categories than inland Adelaide, and under AS/NZS 2312 a higher category calls for a different and more expensive coating system to reach the same service life.

The practical effect for a building owner is that identical structures cost different amounts to coat. A steel awning at Marion is a lighter specification than the same awning at Semaphore, and steel at an Outer Harbor or Osborne site is heavier again. Paying inland rates for a coastal building is a false economy that shows up as rust bleed within a few years. Roof sheeting deserves specific mention because it is the most commonly neglected commercial surface and often the most exposed.

Factory and warehouse roofs across Wingfield, Regency Park, Kilburn, Gepps Cross, Lonsdale and Edinburgh accumulate salt, industrial fallout and dirt, and once the original factory coating begins to chalk the sheeting starts to deteriorate from the top surface down. Recoating at the right time extends the life of the sheet considerably, whereas leaving it until perforation means replacement rather than coating. Roof access, fall protection and the fragility of older sheeting all add cost, and no roof coating job should be quoted without a site inspection. Commercial roofing contractors and roof coating specialists often quote the same building differently because they are assessing different remedies.

Wineries and food production facilities across the Barossa, Clare, McLaren Vale, Coonawarra and the Riverland create a specialised demand that is South Australian in scale. These sites need coatings that tolerate constant wash down, chemical sanitisers, acidic product spillage and high humidity, and in food contact zones they need finishes suitable to that use with documentation to support an audit. Epoxy and polyurethane systems dominate here rather than acrylics. Vintage timing also compresses the program severely, because the work has to be complete before fruit arrives and nothing can be in the way once it does. Contractors who work this sector plan around the crush calendar, and those who do not will quote a window that does not exist.

Defence and heavy industry add a further category in South Australia that most states do not carry to the same degree. Shipbuilding and defence facilities at Osborne, along with major mining operations in the state's north, generate sizeable protective coating work with requirements that go well beyond ordinary commercial painting, including site inductions, security clearances, contractor accreditation and stringent documented inspection regimes. Contractors working in that space are a distinct segment of the market. If your project sits on or adjacent to such a site, the access and compliance requirements will shape the tender list before price does.

Safety, Lead and Asbestos

Commercial painting is high risk work more often than people assume, and the two dominant risks are falls and hazardous substances. Work health and safety in South Australia operates under the state Work Health and Safety Act and Regulations, and as the person engaging a contractor you carry duties of your own rather than transferring all responsibility with the contract. Workplace safety requirements are administered by SafeWork SA. Working at height drives most of the compliance on commercial jobs.

Elevating work platforms require the operator to hold the relevant high risk work licence once boom length reaches the prescribed threshold, scaffolding above the prescribed fall height must be erected by a licensed scaffolder, and any work where a fall is possible requires a documented control rather than an improvised one A safe work method statement is expected for high risk construction work and should be provided before the crew arrives rather than produced afterwards. Asking for it is normal practice and a contractor who treats the request as unusual is not one you want on a roof. Lead paint is the substance issue that catches owners of older South Australian commercial buildings most often. Lead content in Australian domestic paint was progressively reduced through the second half of the twentieth century, and any building painted before around 1970 should be treated as likely to contain lead in older coats, with pre-1950 buildings almost certain to. Disturbing those films by sanding, blasting, burning or scraping generates lead dust and fume.

AS 4361.2 is the guide to lead paint management for residential, public and commercial buildings and it sets out how to assess, contain, remove and dispose of lead coatings safely. In practice that means testing before disturbance before the fact, containment and sheeting, wet methods or extraction instead of dry sanding, exclusion of occupants and passers by, personal protective equipment and washing facilities, and disposal of waste and wash water as controlled material not into a skip or a stormwater drain. Costs rise once lead is confirmed and the difference between a lead-safe quote and an ordinary one is not a margin question. Health information about lead exposure is published by SA Health, and South Australia has a longer institutional history with this issue than most states given the ongoing lead management programs around Port Pirie. Lead paint removal specialists handle the work where a building tests positive.

Asbestos is the parallel issue and it appears in commercial buildings far more often than in houses. Any workplace built before the end of 2003 is required to have an asbestos register, and painters working on eaves, soffits, wall sheeting, fire doors, service risers and roof sheeting on older commercial stock can readily disturb asbestos containing material through sanding, drilling or pressure cleaning. The register should be consulted before work starts and the contractor should be shown it. If material needs removal, licensed removalists carry out that work rather than painters. Commercial asbestos removal is a separate licensed trade and should never be folded into a painting scope.

Environmental obligations complete the picture. Discharging paint, wash water, abrasive blast residue or stripping waste into a stormwater drain is an offence under South Australian environment protection law, and commercial sites are more visible and more frequently reported than domestic ones. Proper practice means washing equipment into containment rather than a gutter, capturing blast residue, and disposing of waste paint and solvents through a suitable waste facility. Contractors working to a documented environmental method will describe this without prompting. Requirements are administered by the South Australian Environment Protection Authority.

Working in Occupied Premises

Most commercial painting happens in buildings that cannot close, and managing that is a large part of what distinguishes a commercial contractor from a domestic one. Offices, medical suites, aged care facilities, schools, supermarkets, hotels and clubs all keep operating while the work proceeds, which pushes the job into evenings, weekends, school holidays or staged sections. The loading for out of hours work in South Australia commonly runs between 20 and 50 per cent depending on the hours involved and whether penalty rates apply. That loading usually pays for itself and the arithmetic is straightforward. Compare the additional cost of night work against the revenue lost by closing, the disruption to staff productivity, and the cost of relocating people. For a retail tenancy or a medical practice the trading loss almost always exceeds the loading.

For a back of house store room it almost never does. Product selection changes in occupied buildings and it is a legitimate cost difference rather than an upsell. Low odour waterborne enamels have largely replaced solvent based products for interior trim in occupied commercial spaces, because a traditional oil based enamel will make an office unusable overnight and can linger for days. Most major manufacturers now offer waterborne enamel systems intended for this use, and specifying one is standard practice for occupied work. In healthcare and aged care settings the requirements go further, with antimicrobial and scrubbable finishes, low emission products and strict infection control protocols around dust and access. Mould resistant coatings are commonly specified in wet areas and in buildings with humidity problems.

Schools are a South Australian program in their own right. Painting in operating schools is concentrated into the term breaks, particularly the summer break and the mid year break, which means the entire state's education painting demand competes for the same few weeks. Booking a school repaint in the term before it is needed is far more effective than booking it in the same term, and contractors who do this work regularly have their holiday periods committed well in advance. The same logic applies to any seasonally driven venue, including tourism accommodation on Kangaroo Island and the Fleurieu, which repaints outside peak season, and function centres that work around their event calendars.

Practical site protocols matter more than people expect and belong in the scope. Confirm access hours and after hours entry arrangements, alarm and security procedures, where the crew may park and store materials, whether a site induction is required, how furniture and equipment will be moved and protected, what happens to sensitive equipment and documents, and who signs off each area as complete. Adelaide CBD buildings frequently add loading dock booking, goods lift access windows and building management approvals that must be arranged days ahead. A contractor who asks these questions during the site visit is showing you they have done this before. Commercial cleaning after completion is usually a separate engagement and is best arranged as part of the same program.

Strata and Community Title Buildings

South Australia has its own title structures and the terminology differs from other states in ways that matter when you are organising a repaint. The state uses both strata title and community title, governed by separate legislation, and the owning entity is a strata corporation or a community corporation rather than an owners corporation or a body corporate. Anyone bringing interstate assumptions into an SA building will find the process does not match. Painting of common property is a corporation decision rather than an individual one. That means the work needs to be authorised in accordance with the corporation's rules, which generally involves a resolution at a general meeting, and expenditure above certain thresholds may require a particular type of resolution or notice period. Getting the authorisation wrong can leave individual owners exposed or the contract unenforceable, so the sequence is to establish the authority first and obtain quotes second.

Mixed use buildings across the Adelaide CBD, North Adelaide, Glenelg, Brighton and the inner suburbs complicate this further, because a single building may contain retail at ground level and residential above under different arrangements, with the boundary between common property and lot property affecting who pays for what. Balcony ceilings, entry lobbies, external walls, stair cores, car parks and service corridors all need to be allocated correctly before a scope is written. A quote covering areas the corporation does not own creates a dispute rather than a repaint. Disputes about common property works in South Australia are heard by the South Australian Civil and Administrative Tribunal, which is the practical forum for disagreements between owners and corporations, and knowing that pathway exists before a project goes wrong helps before the fact. Tribunal information is published by SACAT. Consumer protections applying to contracts more generally, including misleading conduct and consumer guarantees, are administered nationally by the ACCC.

For corporations the practical advice is to plan cyclical external painting rather than reacting to visible deterioration, because a repaint carried out before the coating fails is materially cheaper than one carried out afterwards. Once a film has broken down and moisture has reached the substrate, the preparation cost rises sharply and render and timber repairs enter the scope. Building a repaint cycle into the maintenance plan and funding it through the sinking fund spreads the cost and avoids the special levy that a failed facade eventually forces. Strata inspections are the usual way to establish where a building sits in that cycle, and unit and apartment painting covers the interior side of the same buildings.

What Drives the Price

Substrate condition is the dominant variable and it is assessed on site rather than estimated from a plan. Sound previously painted plasterboard is the cheapest surface to repaint, sound render is next, weathered render and masonry rise from there, and deteriorated steel sits at the top because preparation on steel is a mechanical process with its own standards and equipment. Two buildings of identical area can differ by more than double on condition alone. Access is the second driver and on anything above single storey it frequently becomes the largest single component. Ladders and trestles cost almost nothing, scissor lifts and knuckle booms carry daily hire plus delivery, scaffolding carries erection, hire by the week and dismantling, and swing stages and rope access carry engineering, certification and specialist crews. Hire equipment through the major national suppliers is readily available across metropolitan Adelaide but availability thins considerably in regional South Australia, where mobilisation of a lift to a Riverland or Eyre Peninsula site can add days to a program and a meaningful sum to the quote.

The coating system itself moves the price less than people expect on decorative work and more than they expect on protective work. The difference between a mid range and a premium interior acrylic across an office might be a few dollars per square metre, and the premium product is usually worth it on a wall that will be washed regularly. The difference between a single pack acrylic and a three coat inorganic zinc, epoxy and polyurethane system on steel is an entirely different order of magnitude, because the materials cost more, the application is slower, the surface preparation is far more demanding and the work is inspected. Area and repetition work in your favour A large uninterrupted warehouse wall is quick and cheap per square metre, while a small area broken up by windows, service penetrations, pipework, signage and equipment is slow and expensive per square metre even though the total is smaller. This is why quotes on complex small jobs can look disproportionate. Cutting in is the slow part of painting and everything that creates an edge creates cutting in.

Weather governs the program in South Australia in a way that is specific to the local climate. Adelaide's dry summers give long reliable exterior working windows, which is an advantage over most Australian capitals, but the heat introduces its own limit because coatings applied to a surface above roughly 35 degrees will dry too fast, giving poor flow, poor adhesion and lap marks. On a north or west facing wall or on steel in January the surface temperature runs well above air temperature, so work shifts to the shaded side of the building and to early mornings. Winter brings the opposite problem, with low overnight temperatures, heavy dew and high humidity delaying starts until mid morning, and protective coatings generally requiring the substrate to sit at least three degrees above dew point before application. The Limestone Coast and the Adelaide Hills lose more days to rain and damp than the plains do. A contractor who builds these constraints into the program is giving you a realistic date rather than an optimistic one.

Program compression is the last driver and the one most often self inflicted. A job that could run comfortably over three weeks and gets squeezed into eight nights requires more crew, more supervision and more equipment simultaneously, and the rate reflects that. Giving a contractor a realistic window is one of the few ways a client can directly reduce the price without reducing the scope. Planning the program with realistic curing windows costs nothing and removes the loading entirely.

Commercial Painting Costs Across Adelaide

Pricing across metropolitan Adelaide reflects building type, access and operating hours far more than location. The CBD and North Adelaide carry older stone and brick stock with heritage overlays and strict building management protocols, the inner east and inner south around Norwood, Unley and Goodwood mix heritage shopfronts with modern fitouts, the northern and western industrial corridors through Wingfield, Regency Park, Kilburn, Dry Creek and Edinburgh generate warehouse and factory volume, and the southern corridor around Lonsdale and Tonsley carries a mix of light industrial and commercial. Interior painting and exterior painting specialists cover the smaller commercial jobs at the domestic end of the scale. Two buildings on the same street can price very differently on access alone.

Two things show up repeatedly across Adelaide commercial jobs and both are worth planning around. Heritage status discovered after a contractor has mobilised is the most common cause of a stopped job in the older commercial strips, and salt damp identified at the preparation stage is the most common cause of a scope changing mid project. Both are found by a proper site inspection before quoting rather than by a phone estimate. Both are identified at inspection stage rather than discovered mid-project, provided somebody looks.

Regional South Australia

Regional pricing sits differently rather than simply higher. Base rates in larger regional centres are often slightly below metropolitan rates because overheads are lower, but travel, accommodation and equipment mobilisation appear as distinct components and can dominate on smaller jobs. The further from Adelaide and the smaller the job, the more those components matter, which is why bundling all the work on a regional site into one visit produces far better value than staging it. Property maintenance contractors covering regional areas often coordinate several trades into a single mobilisation for exactly this reason.

The Limestone Coast has a climate profile that changes programs. Mount Gambier and the surrounding district receive more rainfall than Adelaide and carry higher humidity through winter, which shortens the reliable exterior painting season and pushes major external work toward the warmer months. Contractors who work the region build that into their scheduling and will tell you plainly that a July exterior repaint is a poor idea. Interior work moves in the opposite direction and fills the winter, so aligning your project to that rhythm often improves both price and availability.

The upper Spencer Gulf towns present the state's most demanding coating environments outside dedicated industrial sites. Whyalla, Port Pirie and Port Augusta combine marine salt with industrial emissions, which places them in high corrosivity categories where ordinary architectural systems will not achieve a reasonable service life on exposed steel. Buildings in these towns need a specification written for the environment rather than a general commercial one, and owners who have been through a premature failure usually already know this. The cost premium buys years rather than appearance.

Availability rather than price is the real constraint in the Far North, the Eyre Peninsula and the Flinders. There are simply fewer commercial painting businesses operating west of Port Augusta and north of Port Pirie, crews often travel from Adelaide or Whyalla, and accommodation and mobilisation appear as real line items. Lead times of several weeks are normal and shorter notice attracts a premium. Grouping work, giving generous notice and being flexible on timing are the three levers that work out there. Pressure cleaning is frequently combined into the same visit to make the trip worthwhile.

What to Look Out For

Check the building work contractor licence before you do anything else and check it on the public register rather than on the quote. Licensing is a legal requirement for building work in South Australia, verification takes a minute, and an unlicensed contractor leaves you with limited recourse if the work fails. Ask for the licence number and look it up yourself. Treat any quote that does not describe preparation as incomplete not competitive. The preparation clause is the part of the scope that determines whether the finish lasts, and its absence is the single most reliable predictor of a job that will need redoing. If two quotes differ and only one describes preparation in detail, you have probably found the reason for the gap rather than a bargain.

Be wary of a quote that specifies coats without specifying products. Naming a product and a system allows you to check coverage rates, recoat times and intended use, whereas a promise of two coats of premium paint gives you nothing to check against. Manufacturers including Dulux, Wattyl, Haymes, Taubmans and Resene publish technical data sheets for their commercial and protective ranges, and those sheets state the recommended film build and the substrates each product is designed for. A specification that matches the data sheet is a specification you can hold someone to.

Ask directly about heritage status and about lead and asbestos on any building constructed before the 1980s, and get the answers in writing before work starts. These are the three items most likely to stop a job mid stream, all three are foreseeable at inspection stage, and a contractor who has not raised any of them on an obviously old building has either not looked or is hoping the issue does not surface. Testing before disturbance costs far less than remediation afterwards. A contractor who has not raised either on an older commercial building has not assessed it properly.

Confirm what happens if the surface fails and how long the contractor stands behind the work. A defects liability period should be stated in the contract with a clear description of what it covers, and workmanship failures such as peeling, flaking and poor adhesion are the failures worth covering. Manufacturer product warranties are separate from contractor warranties and neither substitutes for the other, so establish both. A warranty that exists only as a verbal assurance is not a warranty, and warranties from a business without an established trading history are worth what the business is worth in three years time.

Look closely at how variations will be handled, because commercial painting scopes change once preparation begins and hidden substrate problems appear. A good contract sets out how a variation is identified, priced, approved and documented before the work proceeds. Without that mechanism you get either an unwelcome invoice at the end or a contractor absorbing a loss and cutting corners elsewhere to recover it. Agreeing the variation process before work starts is worth more than a small difference in the headline rate.

Finally, watch for a program that looks too good. A crew promising to complete a full commercial repaint in a fraction of the time others have quoted is either bringing far more labour, which will show in the price, or is planning to skip preparation and drying time. Coatings have minimum recoat intervals that cannot be compressed by enthusiasm, and a schedule that ignores them produces a finish that fails early. Spray application genuinely does speed the work on suitable surfaces, so a fast program backed by the right method and equipment is credible where a fast program backed by nothing is not.

What to Look for in a Quote in SA

A commercial painting quote worth comparing states the scope, the system and the program not just a price. It should list the areas and surfaces included and specifically note anything excluded, describe the preparation to be carried out including cleaning method, repairs and any priming or sealing, name the products and the number of coats for each surface type, state the access method and who provides the equipment, set out the working hours and the program with a start and finish date, address protection of the building's contents and the making good of any damage, state the defects liability period, and set out payment terms. Preparation and exclusions are the two items most often left vague, and both are where a cheap quote becomes an expensive job. Describe your building properly when you enquire, because the details determine which contractor is even suitable. Say what the building is used for and whether it stays occupied, give the approximate area and number of storeys, describe the substrates involved such as plasterboard, render, masonry, steel or roof sheeting, state the approximate age of the building, mention any known heritage listing, and note any visible problems such as peeling, cracking, rust or damp at the base of walls. Photographs of each elevation and close ups of any problem areas save an enormous amount of back and forth.

Get at least three quotes on commercial work and insist that all three quote the same scope. Where a contractor believes the scope is wrong they should say so and quote an alternative alongside, which is useful information rather than a complication. Posting the job once here brings responses from several licensed contractors so the scopes and inclusions can be read side by side rather than chased individually. Settle the licence, the scope, the preparation, the products, the program and the defects position before anyone starts, and keep the technical data sheets with your building records because they tell whoever repaints the building next what is already on the wall. That single file saves the next contractor a considerable amount of guesswork and saves you paying for testing you have already effectively done. You will also find commercial flooring contractors here for the work that usually accompanies a repaint.
