The General Environmental Duty and Where Wash Water Goes

This is the largest single difference between commercial and domestic exterior cleaning in Victoria, and businesses arranging the work for the first time routinely underestimate it. The general environmental duty obliges anyone conducting an activity that may give rise to a risk of harm to human health or the environment to take steps that are reasonably practicable to eliminate or minimise that risk. It is framed as an ongoing preventative obligation rather than a list of things nobody may do, which changes how a business should approach engaging a cleaning contractor. That preventative framing is the part most businesses miss entirely.

The practical consequence is that responsibility does not transfer with the invoice. A business engaging an operator who sends contaminated water into a stormwater pit has not discharged its own duty simply by paying somebody else to hold the hose, because the duty attaches to the activity being conducted on its behalf. Asking how the water will be handled is therefore part of meeting an obligation rather than an optional courtesy. On a site of any size, have that answer confirmed in writing.

Two destinations exist and confusing them causes most of the trouble. Stormwater drains run untreated to creeks, the Yarra, Port Phillip Bay and eventually the ocean, so nothing beyond clean rainwater belongs in them. Sewer flows to a treatment plant and can accept contaminated water, which makes it the correct destination for commercial wash water and precisely why access is controlled. An agreement exists so the water authority knows what is entering the system and in what volume.

Access to the sewer is granted, not assumed because a drain happens to be nearby. Melbourne is served by retail water businesses covering different parts of the metropolitan area, while regional sites fall to their regional water corporation, and the arrangement is a trade waste agreement, trade waste being liquid waste produced by a business activity, covering what may be discharged, in what volume and with what pre treatment. Lifting a grate and pointing a hose into it satisfies nothing, and a contractor suggesting it is creating exposure for the business that engaged them. Put the disposal question to the contractor before anybody starts work.

Pre treatment often forms part of that agreement and means actual equipment. Depending on the contamination it can involve a silt trap, an oil water separator, a grease arrestor or filtration before anything enters the sewer, and a contractor working carparks and forecourts regularly carries vacuum recovery and filtration as standard. Where a site already has an installed separator, correct disposal may be as simple as directing water to the right point. Walking the site generally settles the question within minutes.

Three short questions sort contractors quickly at quoting stage. Ask how the water gets captured, where it goes and under what authorisation, then request the paperwork where the site produces meaningful contamination. Anybody working commercial sites regularly answers all three without pausing, while somebody treating the question as unusual has revealed where they normally work. You learn more from those three answers than from any capability statement. The domestic position on containment sits at pressure cleaning. Oversight of the duty rests with EPA Victoria.

Keeping the record protects the business afterwards. Filing the contractor's disposal documentation alongside the invoice demonstrates that reasonably practicable steps were taken, which matters if a neighbouring business or a member of the public reports discoloured water entering a pit and somebody traces it back to your forecourt. Keep that documentation with the building maintenance file.

Owners Corporations and Who Authorises the Work

Owners corporations are among the largest buyers of exterior cleaning in Victoria and the authorisation question catches individual owners and new committee members alike. External walls, roofs, common driveways, shared paths, stairwells, foyers, carparks and bin areas in a scheme are generally common property maintained by the owners corporation, which makes cleaning them a scheme expense decided through the scheme rather than by any individual lot owner. Organise it yourself as a lot owner and the money is generally unrecoverable. Establishing who holds responsibility first avoids that outcome.

Getting work approved depends on the amount and how the scheme operates. Routine maintenance within the approved budget is typically arranged by the committee or the owners corporation manager without a general meeting, while larger works may need a decision at a general meeting and occasionally a special levy. Starting with the manager is the efficient route, and related common property work sits with owners corporation and strata painting. Your manager can tell you which approval threshold the job falls under.

Lot boundaries rarely sit where owners assume. Courtyards, balconies and car spaces forming part of a lot are generally the owner's responsibility, though even those can carry rules about what may be used and when work may proceed, and the wall enclosing a courtyard is typically still common property. Reading the scheme rules before arranging anything heads off a difficult conversation afterwards. A courtyard surface and the wall enclosing it frequently sit on different sides of the boundary.

A risk argument sits alongside the appearance one and committees find it more persuasive. Moss and algae on a shaded common path, a slippery stairwell entry or an oily carpark ramp create a genuine hazard, and a Victorian winter keeps those surfaces wet for weeks at a time rather than hours. Regular cleaning with dated invoices forms a record of reasonable maintenance, which frequently shifts a proposal from deferred to approved. Duty of care arguments carry further with a committee than presentation ones.

Programming work around residents takes more thought than an empty commercial property does. Residents need notice, shared driveways cannot close without an alternative, lifts may need booking for upper level access, and noise limits apply differently in a residential building than in a retail centre. A contractor experienced in owners corporation work raises all of that unprompted. The same authorisation route governs roof and facade work, covered at roof cleaning.

Schemes stretch their budget furthest by grouping common area work into one attendance. Handling driveway, paths, bin bay, common walls and guttering in one mobilisation comes in well under four separate visits, with plumbing at strata and body corporate plumbing and guttering at gutter cleaning. Grouping four areas into a single visit undercuts four separate ones substantially.

Carparks, Forecourts, Loading Docks and Bin Bays

Four commercial surfaces generate most of the work and each carries its own contamination profile. Parked vehicles leave hydrocarbons across a retail or office deck along with tyre rubber, litter residue and growth in untrafficked corners, and how much oil is present determines where the water goes. Leave a deck for several years and it accumulates petroleum residue in quantities that rule out any uncontrolled rinse. Vacuum recovery is standard practice on work of that type.

Basement and multi level decks introduce questions about airflow and where water drains. In an enclosed level the exhaust film covers walls and ceilings alongside the deck, drainage runs to a sump that may have no separator fitted, and working in confined conditions brings its own requirements around airflow and equipment fumes. Electric equipment or mechanical ventilation resolves the problem. Airflow matters as much for the cleaning itself as for the crew.

Nowhere on a typical site accumulates a heavier or more mixed contamination load than the dock. Grease and food waste from delivery vehicles, hydraulic oil from tailgates, spilled product and residue from bins staged for collection all accumulate in a confined area with poor drainage. Degreasing with adequate soak time, known in the trade as dwell time, does the work that pressure alone cannot, and containment is mandatory. Heat achieves far more on hardened grease than pressure ever will.

A bin bay turns into an odour and rodent problem well ahead of looking neglected. Leachate from waste bins pools under and behind them, feeds flies and rodents and produces complaints reaching the manager, and washing the bay on a schedule tackles the source instead of the result. Rodent activity tends to rise through autumn as temperatures drop, with waste handling scope at rubbish removal. Putting the bin bay on a regular cycle tackles the source rather than the symptom.

Fuel forecourts sit apart from other sites because the necessary infrastructure is already installed. An oil water separator normally forms part of the site approval, which makes disposal far simpler where cleaning is routed to it properly, and fuel residue means the products and the capture both have to handle hydrocarbons. Confirm the separator is functioning properly before any work starts.

Line marking gets damaged and forgotten during scoping. Painted bays, directional arrows, accessible parking symbols and hatched exclusion areas all wear under aggressive cleaning, so a carpark clean stripping the markings creates a compliance problem and a repainting cost. Flagging it in advance means the contractor can ease off around the markings, with related work under commercial painting. The deck surface itself behaves as covered at concrete and paver cleaning.

Melbourne Laneways and Outdoor Dining

Laneways define a great deal of commercial Melbourne and they bring considerations no suburban forecourt raises. Many are bluestone laid in the nineteenth century, a fair number sit inside heritage overlays, and a large share now carry outdoor dining, deliveries and pedestrian traffic through the same narrow space. Cleaning one is rarely a simple matter of turning up with a machine. Establishing who owns the laneway alone can take a week.

Ownership is the first question and it is frequently unclear to the businesses using the space. Some laneways are council owned public roads, others are private rights of way shared between adjoining properties, and a few are owned outright by one building with access granted to others. Who pays and who authorises the work follows from that, and establishing it before organising anything saves an argument about the invoice. Title documents or the managing agent will confirm the ownership position.

Heritage bluestone limits the method more than most contractors expect. Original setts and flagging are protected in many precincts, aggressive pressure erodes the surface and disturbs the jointing that holds them in place, and replacing damaged units with matching stone is slow and expensive. A council heritage adviser will confirm what applies, and cleaning is generally maintenance while anything altering the surface may not be. Sourcing and laying matching stone to replace damaged setts is slow and costly. Building exteriors above a laneway follow the methods at house washing.

Outdoor dining has expanded substantially across Victorian municipalities and brings its own conditions. Footpath and laneway seating operates under a council permit, those permits commonly attach cleanliness and maintenance obligations, and the paving beneath tables accumulates food and drink spills, grease carried on foot traffic and organic growth under planter boxes. Scheduled cleaning of that area is generally part of holding the permit rather than an optional extra. Permit conditions differ from one municipality to the next.

For hospitality venues, working around trade is the limiting factor. Venues are occupied through the evening and frequently into late trade, pushing cleaning into early morning windows, and a contractor who cannot work between two and six in the morning offers a laneway venue very little. Those hours attract a premium that cannot realistically be avoided. Venues that plan for those hours secure better contractors.

Grease is the dominant contamination in a hospitality laneway and it behaves differently in cold weather. Kitchen extraction deposits, spilled product and foot traffic transfer build a film that hardens as temperatures drop, which means a Melbourne winter clean needs hot water or steam where a summer one might manage with chemistry alone. Food premises obligations sit with the local council, with health information published by the Victorian health department. Grease that has hardened in the cold needs heat rather than more pressure.

Hours, Access and the Victorian Winter

Most commercial cleaning happens when a site is closed, which shapes both price and what can be achieved. Retail centres, offices, schools and clubs want work done without disrupting trade or occupancy, pushing it to nights, early mornings, weekends and shutdown periods, and each carries a rate above ordinary business hours. Building that into the budget from the outset avoids surprise at tender. Rates outside business hours are the industry norm rather than opportunistic.

Noise governs how late work can run and Victorian councils set it through local laws. Pressure equipment is genuinely loud, municipal local laws impose conditions on when noisy work may be carried out particularly near residential premises, and inner Melbourne sites with apartments above or beside them face tighter limits than an industrial estate. Confirming permitted hours for the specific address before scheduling saves a cancelled visit. Local laws on noisy work vary considerably between councils.

Winter constrains this work in Victoria in ways the warmer states never deal with, and handing a site back is where it bites hardest. A washed floor, ramp or footpath stays slippery until dry, and through June and July a shaded surface in a laneway or under an awning may not dry at all before a site reopens. That means the margin between finishing and handing back needs to be considerably longer than an operator working in a warmer climate would assume. Handback timing belongs in the written scope rather than being assumed.

Product performance drops in the cold as well. Cleaning chemistry works more slowly at low temperatures, so the same result needs longer on the surface or a warmer application, and several products specify a minimum temperature below which they simply underperform. A contractor scheduling a large external clean for a July night is either using hot water or accepting a weaker outcome. Ask whether hot water is being used or the result is simply weaker.

Wherever vehicles operate, traffic management appears as a genuine cost line. Decks, service roads, loading zones and any work touching a public footpath require people and vehicles kept clear, which might mean cones and signs on a modest job or a written plan with certified controllers on a substantial one. Seeing it costed separately is standard, and a quote for a trading carpark that omits it has overlooked something. Confirm whether accredited controllers and signage sit inside the quoted price.

Staged works keep a site trading while cleaning proceeds. Splitting a carpark across several nights, doing half a loading dock at a time or working around a tenancy allows the business to keep operating, and it costs more in mobilisation than a single closure would. Talk that trade off through rather than assuming which way it falls. Staged works suit sites that cannot close at all.

Safe Work Method Statements, Inductions and Insurance

Paperwork trips up domestic operators moving into commercial work more than anything else, and it accounts for most crews refused entry. The statement documents what high risk work is planned, what hazards exist and what controls address them, and most clients and agents require it before letting anybody on site. On this trade it generally addresses height work where applicable, wet surface slip risk, electrical safety near water, chemical handling and keeping the public clear. Ask for it in advance instead of on the morning.

Every site needs its own induction and normally every person as well. Larger properties, shopping centres, industrial facilities and construction sites each run their own covering emergency procedures, site rules and reporting, so a contractor sending different crew members each visit needs every one of them inducted. That paperwork burden is one reason commercial pricing runs above residential. Sending consistent crews reduces that burden across a contract.

Cover levels are higher here and somebody will verify the certificate. Public liability cover of twenty million dollars is a common requirement on commercial and owners corporation work where the domestic norm sits considerably lower, and managing agents generally ask for a current certificate of currency before engagement. WorkCover is the other cover to confirm where a contractor has employees. Check the expiry date on any certificate of currency provided.

Any site with a safety system in place expects chemical paperwork. Data sheets for whatever is being applied, correct storage and handling, and entry in the site register are all expected, and somebody who cannot produce a sheet for the product in their tank creates a problem within any compliance framework. Occupational health and safety obligations are administered by WorkSafe Victoria. Data sheets should stay accessible for the duration of the work.

Registration works differently here than in most trades and deserves clarity. General exterior cleaning does not require building registration in Victoria, which is why documentation and insurance questions carry more weight than a registration number would, while domestic building work above the statutory threshold does require a registered practitioner and any repairs or painting bundled with cleaning may attract it. Registration checks sit with the Building and Plumbing Commission. Registration becomes relevant as soon as repair work joins the scope.

Larger portfolios commonly run a contractor management platform. Many managing agents and facility managers run a platform where insurance, inductions and documentation get lodged and expiry dates tracked, so a contractor already registered on whichever system your agent uses will be considerably easier to engage. Bringing it up early saves a fortnight of onboarding down the track. Your agent can normally tell you which platform they use.

Scheduled Contracts Against Ad Hoc Callouts

A standing arrangement serves most commercial properties better than reactive calls, and the numbers generally bear that out. Maintained on a cycle a surface needs a single pass without any soak, while three years untouched calls for product, waiting and often a repeat pass, which can double the hours across the same area. Contractors price a known recurring commitment below one off attendance because the work is predictable and mobilisation is planned. Predictable work carries genuine value for a contractor pricing it.

Frequency should follow use and season rather than the calendar alone. A busy retail entry or a hospitality laneway may justify monthly attention, a carpark quarterly or half yearly, and common area paths in a residential scheme twice a year, while Victorian winters make the shaded areas the ones needing the shorter cycle. Setting each area on its own frequency keeps the annual figure sensible. Let usage rather than the calendar dictate how often.

A recurring contract still requires each visit's scope committed to paper. Which areas are covered, how often each is done, what constitutes an extra attendance and how variations are costed all need writing down, because contracts that read as broad commitments generate disputes about whether the bin bay was ever included. Exclusions need naming in the document as precisely as inclusions do.

Reactive work retains its place, and agreeing the rate in advance is sensible. Spills, vandalism, storm debris and incidents outside the cycle occur on any commercial site, and having an agreed response rate and timeframe with an existing contractor beats finding somebody at short notice. Agree response terms at the point of signing. Finding a contractor at short notice always costs more than an agreed rate.

A property manager cannot run the contract properly without reporting coming back. Before and after images, a completion record and notes on items such as a damaged bollard or blocked drain turn the contractor into additional site oversight, which established firms provide unprompted. Photographs also settle any dispute about attendance. Most established firms supply that reporting without being asked.

Consolidating exterior work with one contractor reduces annual mobilisations. Washing, gutter clearing, glass and grounds work all require somebody attending the same address, so sequencing them together reduces the cost of each, with glass at window cleaning and wider scope at cleaning services. The saving comes from one setup covering multiple services.

Commercial Cleaning Across Victoria

Melbourne carries the deepest pool of contractors equipped for commercial work and the most demanding compliance environment. Agents with substantial portfolios typically insist on platform registration, elevated cover and complete paperwork, which restricts the field to firms geared for it, and trade waste arrangements are most clearly established across the metropolitan area. Agents running large portfolios narrow the field of eligible contractors sharply.

The CBD and inner city add access limitations that govern how a job gets scoped. Loading dock booking, restricted vehicle access, overnight work windows, footpath occupation permits for anything encroaching on a public area and building management sign off all apply, and a contractor unfamiliar with those requirements will struggle regardless of cleaning ability. Having worked in the building before counts for a lot.

Inner Melbourne also concentrates the heritage substrates. Bluestone laneways, unsealed brick, original render in its cement coating over brickwork, and period shopfronts sit through the commercial core and the inner suburbs, which raises the planning question on graffiti removal and limits what pressure can be applied anywhere near them. Checking the heritage position with council costs nothing and takes minutes.

Geelong, Ballarat and Bendigo support established commercial contractors with a mix of retail, industrial and owners corporation work. All three hold substantial period commercial stock with the same heritage considerations as inner Melbourne, and colder winters compress the outdoor working window further than in the metropolitan area. Booking ahead matters more through the colder inland centres.

Outside the metropolitan area fewer firms cover greater distances, putting travel and scheduling at the front of every conversation. Plant washdown, hardstand areas, silo exteriors and agricultural facilities bring contamination profiles and induction requirements differing from retail work, and water availability on site is a genuine constraint through the drier northern districts. Confirm early what water supply the contractor can draw from.

What Commercial Work Typically Costs

Pricing here runs off area and contamination rather than a job rate, with compliance costs layered above the cleaning. Expect a deck to be priced by the square metre, with the rate reflecting oil load, containment needs and whether the crew works during trade or outside it. Factor in degreasing, soak time and contained disposal and a modest dock can cost more than a far bigger open deck. What is on the surface influences the rate more than how much surface there is.

Rates outside business hours are the industry norm rather than a mark up on the day. Overnight, early morning and weekend attendance typically sits well above ordinary hours, and a laneway venue needing work between two and six in the morning is paying for a crew working antisocial hours with identical equipment. Allowing for it early prevents a shock when tenders return. That premium reflects when the work happens, not what it involves.

Setup makes up more of a commercial price than clients generally anticipate. Recovery units, tanks, filtration, containment and traffic control all arrive regardless of job size, which is why a small attendance reads as expensive per square metre. Grouping areas into one visit shifts that calculation considerably, since the gear turns up either way. A single visit spreads the setup cost across far more scope.

Winter work can carry its own premium and it is worth understanding why. Hot water or steam capability becomes necessary where a cold surface and slow chemistry would otherwise produce a weak result, and longer handback margins mean a crew occupies a site for longer than the cleaning itself takes. Some contractors price a winter external clean above the same job in March for exactly those reasons. Ask the contractor whether seasonal pricing applies to winter work.

Gum and graffiti carry separate pricing on separate bases, the first by concentration and the second by substrate and how long the paint has cured. Both deserve pricing separately at tender rather than folding into a square metre rate, and indicative figures for the underlying cleaning work sit on our pressure cleaning guide. Concentration and paint age are what move those figures.

What to Look Out For

Establish the water's destination before you look at a single price. The general environmental duty applies to your business as well as the contractor, discharging to sewer needs authorisation from the water corporation rather than access to a grate, and stormwater is never an option. Request the answer in writing on significant sites.

Be suspicious of a price well below the others on a site with documentation requirements. Safe work method statements, inductions, higher insurance limits, traffic management and wastewater capture are all real costs, and undercutting the field usually means one or more has been left out rather than delivered more efficiently. Compare what each quote includes before the totals.

Check that line marking has been factored into any deck quote. Aggressive cleaning strips painted bays, arrows and accessible parking symbols, creating a compliance problem and a repainting cost that lands on the client rather than the contractor. Line marked areas belong in the written scope from the outset.

Confirm the handback margin, particularly through winter. A wet ramp, entry or footpath handed back at opening time is a slip hazard, and a shaded Melbourne surface in July may not dry at all within the window an operator has assumed. Winter work needs a much longer drying margin built in.

Check the heritage position before any graffiti removal on period substrate. Bluestone, unsealed brick and original render are common across inner Melbourne commercial frontages, and aggressive removal creates a heritage problem, with consumer guarantees enforced by the ACCC. Council heritage advice comes before anything touches the surface.

How to Get Useful Quotes

List every area with approximate dimensions and the frequency you are after. Carpark, forecourt, loading dock, bin bay, paths and shopfront are separate items on different frequencies, and providing the numbers puts every contractor on the same footing. Rough dimensions for each area will do for a first round of pricing.

Describe accurately what has accumulated on each surface. Deck oil, dock grease, bin bay leachate and entrance gum each require separate products, separate soak times and separate containment. Photographs of each area help a contractor price the load accurately.

State the permitted working hours and any noise restrictions. Overnight, early morning, weekend or shutdown windows change the rate, and a site with apartments above or beside it faces tighter local law restrictions than an industrial estate. Check the council local law before promising anybody a working window.

Spell out the prerequisites for site entry. Inductions, contractor management system registration, insurance limits, Working with Children Check requirements and permit needs all affect who can realistically quote. Listing them upfront avoids a round of correspondence.

Confirm what utilities the site can provide. Supply and pressure, functioning taps, power, after hours key access and the presence of a separator all decide whether a visit can actually be completed. Twenty minutes walking the site settles every one of those questions.

Require every quote to specify areas and frequency, the method and chemistry, the wastewater capture and disposal path, the documentation and insurance, and how variations get priced. Pin those five down and the tenders become comparable, with waste handling covered at skip bin hire. Water disposal and paperwork are most often left unclear.
