What Polished Concrete Costs in WA

Grind and seal runs $65 to $110 a square metre, mechanical polishing $100 to $150 at cream level, $120 to $180 for salt and pepper and $150 to $220 for full aggregate exposure. The spread reflects how much material has to be ground away and how many passes that takes, since exposing stone means removing several millimetres of surface instead of skimming the top. A hundred square metre living area therefore ranges from about $6,500 to $22,000. Rates for all concrete finishes sit at concreting costs, with trade scope at concreting services.

Area affects the rate substantially because the machinery has to arrive regardless. Planetary grinders, dust extraction, vacuums and a generator all need transporting and setting up, so a small bathroom or laundry carries an uneconomic share of that mobilisation, and most polishers apply a minimum charge below about twenty square metres. Doing the whole floor at once is materially cheaper. Splitting a house into stages is the expensive way to do it.

Condition drives the price more than area on any existing slab. A flat, sound, clean slab grinds predictably, whereas one with adhesive residue, paint, levelling compound, cracks or significant undulation needs remedial work at $20 to $60 a square metre before polishing even starts, and that figure cannot be guessed from a photograph. This is why quotes need a site visit. A number given over the phone is close to meaningless here. Two quotes at the same rate can describe entirely different processes, which is the trap here.

Pouring a new slab specifically for polishing adds $10 to $30 a square metre to the concrete cost. Selected aggregate, higher strength, tighter flatness tolerance, no steel fibres and careful curing all cost a little more than a standard slab, and the money is repaid in a better polished result with fewer surprises. It is a decision made before the pour. What a polish-ready slab involves is set out at concrete slab costs.

Grind and Seal Against Mechanical Polishing

These are two genuinely different products sold under one name and the distinction matters more than any other decision on this page. Grind and seal grinds the surface flat and clean, then applies a coating, typically polyurethane or epoxy, which provides the gloss and the protection. What you walk on is the coating. The concrete underneath is simply the substrate holding it up.

Mechanical polishing works the concrete itself. A sequence of progressively finer diamond abrasives cuts and then refines the surface, a chemical densifier is applied part way through to harden the concrete, and further passes burnish it to the chosen gloss, so the finish is the concrete itself and not something on top of it. Nothing can peel off a mechanically polished floor. There is no coating there to fail.

Cost and lifespan pull in opposite directions between the two. Grind and seal is cheaper upfront and can be done on slabs unsuitable for polishing, but the coating wears at doorways and traffic paths and eventually needs stripping and recoating, which is a disruptive and messy job. Mechanical polishing costs more initially and lasts decades. The whole of life comparison usually favours polishing where the slab permits it.

Appearance differs in ways worth seeing in person. A coating sits above the surface and gives a uniform wet look with obvious depth, while a mechanically polished floor has a harder, flatter light that shows the concrete's own character, and photographs flatten the difference almost entirely. Look at both in daylight before deciding. Most established polishers can arrange it. Coatings can be tinted or given a wet look that mechanical polishing cannot reproduce.

Which is appropriate is often decided by the slab, not by preference. A slab with inadequate cover over the reinforcement, one that has been patched extensively, or one where aggregate distribution is poor may simply not polish well, and grind and seal remains a good outcome in those situations. The polisher should tell you which applies. A polisher who offers both is giving you an honest assessment.

Exposure Levels

Exposure describes how much aggregate the grinding reveals and it is the main aesthetic decision. Cream polish removes only the very top layer, leaving mostly cement paste with the occasional glimpse of sand, which gives a soft, almost monolithic appearance closest to a plain floor. Cream is the shallowest cut of the three. It is also the least predictable across a large slab.

Salt and pepper exposure is the middle option and the most popular in Perth homes. Grinding a millimetre or two deeper exposes the fine sand and small stone throughout the mix, producing an even speckled surface that reads as concrete without being plain, and because it cuts past the surface layer it is far more consistent than cream. Most people picture this when they say polished concrete. It suits the majority of residential jobs.

Full aggregate exposure goes deepest and looks closest to terrazzo. Removing several millimetres reveals the large stone in the mix across the whole floor, producing a bold decorative surface where the aggregate itself becomes the design, and this is where selecting the concrete mix beforehand matters most. Full exposure is the dearest of the three levels. It is also the most striking in a large open space.

Consistency of exposure depends on the slab, not the polisher's skill alone. A slab that was poured unevenly, over-worked in places or had extra water added during finishing will have a variable surface layer, so the depth needed to reach consistent exposure varies across the floor, which shows as patchiness. Cutting deeper through the surface layer evens it out. Cream polish on a variable slab is the riskiest combination.

Get samples of each level ground before deciding, ideally on site. A polisher can grind small test patches on your actual slab, which shows exactly what aggregate is in your concrete and how it looks at each depth, and that is far more useful than a showroom sample from a different pour. Grinding a few test patches costs very little. They remove nearly all the guesswork. Cream polish is the level most likely to disappoint on an older slab.

Grit Sequences and Densifiers

Mechanical polishing follows a sequence and skipping steps shows in the result. Metal bonded diamonds at coarse grits do the initial cutting to the chosen exposure, then progressively finer resin bonded pads refine the surface through a series of steps, with each pass removing the scratch pattern left by the one before it. Missing a grit leaves scratches the later passes cannot remove. That is the most common shortcut in cheap work.

A densifier is applied part way through and it does real work. Lithium or sodium silicate reacts with free lime in the concrete to form additional hardened material within the surface pores, which increases abrasion resistance and reduces dusting, and it is what makes a polished floor durable instead of merely shiny. Applying it at the wrong stage wastes it. Skipping it entirely produces a floor that dulls quickly.

Grit level determines gloss and the numbers are worth understanding. Finishing at around 400 grit gives a satin appearance, 800 produces a clear sheen, and 1500 to 3000 gives high gloss with visible reflection, and each additional step adds time and cost. Higher gloss is not automatically better. It shows every footprint and mark far more readily.

A stain guard or penetrating sealer usually finishes the job. Polished concrete is dense but not impervious, so a penetrating impregnator reduces absorption of oil, wine and other staining liquids without changing the appearance or creating a film, and it is renewed periodically instead of stripped. This is different from a coating. It sits within the surface, not on it.

Edges and corners need separate equipment and take disproportionate time. A large planetary grinder cannot reach within a hundred millimetres of a wall, so edging machines and hand tools finish the perimeter, and matching the edge to the field is genuinely skilled work. Poor edge work is the giveaway on a cheap job. Look at the perimeter when inspecting a finished floor. Each grit step typically takes a full pass across the whole floor.

Is Your Existing Slab Suitable

Not every slab can be polished and finding out early saves disappointment. The polisher needs enough sound concrete above the reinforcement to grind into, reasonable flatness, an absence of extensive patching, and aggregate distributed evenly enough to expose consistently, and a slab failing on any of those may be better suited to grind and seal or an overlay. A polisher on site answers the question in ten minutes. Most polishers will assess a slab at no cost.

Cover over the reinforcement is the hard limit, and it is tighter on Perth coastal blocks. Grinding down to exposed mesh or bar is a structural problem as well as an ugly one, so a slab with shallow cover cannot be taken to full aggregate exposure, and on some older slabs even salt and pepper is marginal. Slabs poured near the coast carry deeper specified cover to protect steel from salt, which usually works in your favour here, while older inland slabs are sometimes shallower than the drawings suggested. The polisher can test the depth available. Cover requirements are the reason a new slab poured for polishing is specified differently. Metal bonded diamonds do the cutting and resin bonded pads do the refining.

Flatness determines how even the exposure will be. Grinding follows the existing surface rather than levelling it, so a slab with undulation will expose deeply on the high points and barely at all in the hollows, producing a visibly uneven result, and correcting that means grinding the whole floor down to the lowest point. Levelling an entire floor by grinding gets expensive quickly. Floor levelling options sit at floor levelling and screeding, and timber alternatives at floor sanding and polishing.

Old adhesives, coatings and levelling compounds all have to come off first. Tile adhesive, carpet glue, vinyl residue, paint and self levelling compound each require removal before polishing, and some are far more stubborn than others, with old bitumen based adhesives being particularly slow. This is the remedial work in the quote. It is also the item most likely to be underestimated sight unseen.

Cracks and penetrations need addressing, not ignoring. Existing cracks can be filled and become a feature or a visible flaw depending on how they are treated, saw cuts and construction joints need filling with a suitable material, and old plumbing penetrations show as patches that will never quite match. Discuss how these will be handled. A polisher who points them out before quoting is being straight with you.

Pouring a Slab for Polishing

A slab intended for polishing is specified differently from the start and it costs a little more. Aggregate is selected for appearance rather than economy, strength is usually higher, flatness tolerance is tighter, steel fibres are avoided because they show at the surface, and curing is managed carefully to give a consistent surface layer. The premium is $10 to $30 a square metre. The improvement in the finished result is considerable. Old bitumen based adhesives are the slowest of all to remove.

Aggregate selection is the decision that shapes the final appearance. The stone in the mix is what shows at salt and pepper and full exposure, so choosing local granite, river pebble or a specialty aggregate is effectively choosing the floor's colour and pattern, and it has to be nominated when the concrete is ordered. There is no changing it afterwards. Discuss it with both the concreter and the polisher.

Flatness has to be built in during the pour. Achieving a consistent exposure depends on the slab being flat within a tighter tolerance than a normal floor, which means careful screeding and power trowelling, and a slab that is out of tolerance can only be corrected by grinding the whole surface down. Tell the concreter it will be polished. It changes how they finish it.

Coordination between trades matters more than on a normal slab. The concreter, the polisher and the builder all need to agree the specification before the pour, and the polisher should ideally see the slab within days of it being placed so any surface issues are identified early. Getting them talking is your job as the client. It prevents the finger pointing that otherwise follows a poor result.

Protection between pour and polish is frequently overlooked. A slab that will be polished months later needs protecting from paint spills, adhesive, mortar droppings and impact damage during the rest of the build, since every mark has to be ground out afterwards. Laying protection over a fresh slab costs almost nothing. Grinding out a builder's paint spill is not.

Gloss Levels and Appearance

Gloss is a separate decision from exposure and people frequently conflate the two. Exposure is how much stone shows, gloss is how reflective the surface is, and you can have full aggregate exposure at a matte finish or cream polish at high gloss. The two are chosen independently of each other. Understanding that makes the sample process much clearer.

Matte and satin finishes suit family homes better than most people expect. A lower gloss hides footprints, dust and minor scratching far better than high gloss, needs less frequent buffing, and reads as contemporary rather than commercial, which is why many Perth residential jobs finish at the satin end. High gloss photographs beautifully in a showroom. It is harder to live with day to day. Steel fibres reaching the surface are impossible to grind out neatly.

High gloss suits large open spaces and good natural light. The reflection amplifies light through a room, which works well in an open plan living area with big windows, though it also shows every mark and requires more upkeep to stay looking its best. It is a genuine aesthetic choice. Neither end of the range is objectively better.

Colour can be introduced but the options differ from other finishes. Concrete dyes penetrate the polished surface and give translucent colour, while oxide in the original mix colours the paste between the aggregate, and the two produce quite different effects that are worth seeing before choosing. Dyes are applied during the polishing sequence. Oxide has to be in the concrete from the beginning.

Slip Resistance and Safety

Polished concrete is safe when dry and needs consideration when wet. A dense polished surface has good slip resistance underfoot in normal dry conditions, and the concern arises in entries, bathrooms, laundries and around pools where water gets onto the floor, which is where slip rating becomes a real design question instead of a technicality. AS 4586 sets out the test methods and classifications used to rate a finished surface, and AS 4663 covers testing floors already in service, both published through standards.org.au. Find out what classification a proposed finish achieves in the wet.

Gloss level and slip resistance are related but not simply. A high gloss floor is not automatically more slippery when dry, though the smoothness that produces high gloss does reduce wet grip, and a lower gloss finish generally performs better in areas that get wet. Treatments exist to improve wet slip resistance. Raise those treatments if the floor extends into a wet area.

Entry points deserve particular thought in Perth. Sand tracked in from outside acts like an abrasive between shoe and floor, which is a genuine slip consideration as well as a wear one, and a good mat system at every external door addresses both problems at once. Perth blocks generate more of it than most. Sand is simply a fact of life on a Perth block.

Pool surrounds are generally the wrong place for a polished finish, and liquid limestone or exposed aggregate is the usual answer outdoors. Wet feet, constant water and barefoot traffic all point toward a textured surface instead, which is why exposed aggregate is the common choice around Perth pools, and a polished floor stopping at the door to a pool area is the sensible boundary. The textured alternative is priced at exposed aggregate concrete costs. Leave anything that gets genuinely wet in a textured finish. Satin finishes are the most common choice in Perth homes for good reason.

Silica Dust and Site Safety

Every pass of a grinder throws off respirable crystalline silica, and the rules governing it have changed markedly. Fine silica dust causes irreversible lung disease, and the exposure standard has been reduced nationally with a much stronger emphasis on engineering controls, which has changed how this trade operates on site. Every professional polisher now works with dust extraction. A crew grinding without it is not one to engage.

Proper dust control means industrial extraction, not a shop vacuum. Grinders are shrouded and connected to high capacity extraction units with appropriate filtration, and the dust is contained and disposed of rather than discharged into the air, which also happens to keep your house clean during the work. Workplace obligations are administered by worksafe.wa.gov.au. The national exposure standard and its guidance material sit with safeworkaustralia.gov.au. Dye and oxide can be combined, though the result is worth testing first.

Wet grinding is the alternative approach and it has its own considerations. Water suppresses dust effectively, though it generates slurry that must be contained and disposed of properly rather than washed into a stormwater drain, and it is messier inside an occupied house. Wet and dry methods are both legitimate when done properly. Find out which method they use and where the residue goes.

Staying in the house through the work takes some organising. Polishing is noisy, the area has to be isolated, and even with good extraction there is disruption for several days, so most households either move out briefly or seal off the working area. Get a realistic figure for how long the floor is out of use. Sequencing it before you move in is far easier where that is possible.

Where It Works in a WA Home

Open plan living areas are where polished concrete performs best. Large uninterrupted floors show the finish to advantage, the thermal mass helps moderate temperature swings in a Perth summer, and the durability suits high traffic family spaces better than most alternatives. It also connects visually to outdoor concrete. Alfresco and indoor floors in one material reads well, and outdoor areas are priced at concrete driveway costs.

Kitchens suit it for practical reasons as well as appearance. The surface is impervious enough to wipe clean, unaffected by spills that would damage timber, and comfortable to stand on for reasonable periods, though dropped glassware breaks comprehensively and it is unforgiving underfoot over long stretches. A rug under the dining table solves the comfort question. Nothing solves the dropped glass question. Wet areas should be assessed against the relevant slip classification before committing.

Garages and workshops are an excellent application and frequently overlooked. A polished garage floor resists oil staining far better than bare concrete, sweeps clean, brightens the space considerably and stands up to vehicle traffic without difficulty, and it costs less than the equivalent area indoors because expectations for finish quality are lower. Coating alternatives sit at garage flooring, and the slab beneath is priced at concrete slab costs. Coating and polishing both work well in a garage.

Bathrooms and laundries need care but are not excluded. Slip resistance in the wet is the consideration, and a lower gloss finish with appropriate treatment works, though falls to floor wastes and waterproofing all have to be right first and those are not polishing questions. Get the waterproofing correct regardless of the finish. It matters more than the surface above it.

Bedrooms divide opinion and the answer is personal. The material is hard and cool underfoot, which suits a Perth summer and less so a Great Southern winter morning, and rugs address it at the cost of covering the floor you paid for. Consider how the room is used. Continuity through the house is the usual argument for including them.

Common Problems

Uneven exposure is what people complain about most, and the slab is nearly always the cause. Where the original pour had inconsistent finishing, extra water worked into the surface, or variable aggregate distribution, the depth needed for even exposure varies across the floor, and no amount of skill fully compensates. Taking the cut deeper produces a more even result. Test patches beforehand identify the risk.

Trowel marks and burnish lines can appear on shallow cuts. A slab that was power trowelled hard develops a densified surface layer with visible swirl patterns, and a cream polish that only skims the top can leave those patterns showing, which surprises people expecting a uniform finish. Grinding past that layer removes the swirls entirely. Cream polish on a hard trowelled slab is a known risk.

A floor that dusts points straight at the densifier. A polished floor that produces fine white powder underfoot has either not been densified properly or was ground with the densifier applied at the wrong stage, and the fix is reapplication and repolishing, not sealing over the top. Properly densified concrete does not dust. Dusting is a straightforward diagnostic to make. Extraction units run continuously and are noticeably loud inside a house.

Staining happens on floors left unprotected. Polished concrete is dense but still absorbs oil, wine and similar liquids if the stain guard has not been applied or has worn away in a traffic path, and prompt cleaning deals with most incidents while sitting on a spill overnight generally does not. Put the impregnator back on when it is due. Nothing else protects the floor so cheaply.

Cracks appear over time and how they were handled matters. All concrete cracks eventually, and a polished floor makes them more visible than carpet or tiles would, which is why existing cracks are filled and future control joints are treated as part of the design instead of a defect. A crack in a polished floor is not a polishing failure. It is concrete behaving as concrete does.

Maintenance and Repolishing

Day to day care is simpler than most floor coverings. Sweeping or dry mopping to remove grit, and damp mopping with a pH neutral cleaner, is the whole routine, and the enemy is abrasive material tracked in, not anything you might spill. Keep acidic cleaners away from it entirely. Vinegar and similar products etch the surface over time.

Grit is what wears a polished floor and Perth supplies plenty of it. Sand carried in on shoes acts as an abrasive under foot traffic, dulling the finish along walkways over years, and good doormats at every external entry make a measurable difference to how long the polish lasts. This matters more here than in most cities. Mats are the cheapest maintenance you can buy.

The stain guard needs periodic renewal. A penetrating impregnator wears in traffic areas and is typically reapplied every few years depending on use, which is a straightforward job requiring cleaning and application instead of any grinding. Renewal is what preserves the stain resistance. Neglecting it is how kitchen floors acquire permanent oil marks.

Repolishing refreshes a worn floor without replacing anything. Where traffic paths have dulled after many years, a light repolish through the finer grits restores the finish at $40 to $90 a square metre, which is far less than the original job and dramatically less than replacing a floor covering. This is the argument for mechanical polishing over coatings. A coated floor needs stripping first. Thermal mass works in your favour through a Perth summer.

Coated floors follow a different maintenance path. Grind and seal surfaces need the coating maintained and eventually stripped and recoated, which is more disruptive than repolishing and needs doing more often in high traffic areas, so the lower upfront cost is partly repaid over time. Neither polishing nor coating is maintenance free. The difference is what the maintenance involves.

Choosing a Polisher

The equipment barrier in this trade is low and the skill barrier is high, which produces a wider quality range than in most concrete work. A grinder can be hired by anyone, whereas reading a slab, judging the cut depth, completing a grit sequence properly and finishing edges to match the field takes real experience. Find out how long they have been polishing specifically. Concreting experience is not the same thing. Garage floors polish well at a lower finish standard and lower cost.

Put it to them: how much of your work is mechanical polishing against grind and seal? An operator who does mostly coatings and occasionally polishes is a different proposition from one who polishes daily, and the answer also tells you which product they will steer you toward. Both are perfectly legitimate businesses to run. You simply want to know which you are dealing with.

The usual business checks are the starting point. A current ABN, public liability cover and a written quote with the process specified are the minimum, and any established operator produces them without hesitation, particularly given they will be working inside your home with heavy machinery. No specific licence covers concrete polishing in this state. You can look up what registrations a business should hold at ablis.business.gov.au.

Consumer guarantees cover the workmanship whatever a quote says. A floor with visible scratch patterns from a skipped grit, an edge that does not match the field, or dusting from an absent densifier are all workmanship questions, and the framework is explained by the ACCC. Raise anything that concerns you before the crew leaves site. Photographs under raking light show scratch patterns most clearly.

Warranty terms are worth reading on a floor this expensive. A polished floor should not require rework within a few years, and an operator offering a meaningful warranty on the polishing itself is signalling confidence in their process, while one offering nothing may be telling you something. Establish what is covered and for how long. Get it in writing alongside the quote. Surface layer variation is the single biggest cause of an uneven result.

Planning the Work in Your Home

Sequencing polishing correctly within a build or renovation saves considerable trouble. The ideal point is after the messy trades have finished and before joinery, skirting and painting go in, because grinding to a wall edge is far easier without skirting boards and because later trades will otherwise mark a finished floor. Agree the order of trades with your builder at the outset. Getting it wrong means either damage or extra masking.

Skirting and door clearances change once a floor is ground. Removing a few millimetres from the surface alters the gap under doors and the relationship to skirting, which matters where existing joinery is staying, and it is worth checking before the grinding starts rather than discovering a gap afterwards. On a new build it is easily allowed for. On a renovation it needs measuring.

Living in the house during the work is possible but unpleasant. The area has to be isolated, the noise is considerable, and the floor is out of use for several days between grinding, densifying and the final passes, so most households either stage the work room by room or move out briefly. Get a realistic day count up front. Polishers generally give an accurate one because their scheduling depends on it.

Adjoining floor finishes need a transition detail. Where polished concrete meets tile, timber or carpet, the level difference and the junction need resolving, and this is easier to plan than to fix, particularly where the concrete ends up lower after grinding. Carpet and other coverings are quoted at carpet installation and replacement. Decide the transitions before work starts.

Kitchen and joinery installation timing interacts with the floor. Polishing before cabinetry means a continuous floor under the units and easier grinding, while polishing after means no risk of damage during installation but grinding around a fixed kickboard, and each approach has adherents. Raise the sequencing with your cabinetmaker early. Kitchen work is covered at kitchen renovation costs.

Western Australian Conditions and Suppliers

Perth housing stock suits this finish better than most people assume. Slab on ground construction is close to universal across the metropolitan area, so the concrete floor is already there under the carpet or tiles in the majority of homes built since the 1960s, and much of it sits on stable Swan Coastal Plain sand classified at the low end of AS 2870. That means less historic movement and fewer cracks to deal with. Homes in the Perth Hills on clay and laterite are the exception and need assessing more carefully.

The concrete itself comes from a small number of suppliers and that shows in what you can expose. Holcim, Boral, Hanson and BGC batch most residential concrete across the Perth basin, and their standard mixes use local granite and limestone-derived aggregate that produces the grey and warm-toned speckle typical of polished floors here. A slab poured in Karratha exposes differently from one poured in Fremantle. The aggregate the local plant draws on is the reason.

Grinding equipment in Western Australia is largely the same as elsewhere, with HTC, Husqvarna and Scanmaskin planetary machines being common, paired with dedicated extraction units. What matters more than the badge is whether the extraction is properly matched to the grinder. Find out what extraction unit runs with it. An undersized vacuum on a large machine is the most common gap in dust control.

Perth's dry climate helps at the finishing stage. Low humidity through much of the year suits densifier reaction and sealer application, whereas the South West and Great Southern winters bring conditions where products take longer to cure and application windows narrow. Regional application timing is worth raising at quote stage. Operators working those areas plan around it as routine.

Sand is the one WA factor that works against a polished floor over time. Blown sand from unsealed verges, coastal exposure and the general dryness of a Perth summer means more abrasive material reaches the surface than in wetter cities, and that is what dulls walkways. Entry matting matters more here than almost anywhere. It is the cheapest protection available to a household.

Perth Metro Costs

Perth has a reasonable depth of concrete polishing capacity, concentrated in the metropolitan area and serving both commercial and residential work. That competition keeps rates sensible and makes three comparable quotes achievable, though the quality range is wider than in most trades because the equipment barrier is low and the skill barrier is high. What moves a Perth quote is the slab condition and the exposure level far more than the suburb. Access for heavy machinery is the other variable worth mentioning. pH neutral cleaners are widely available and inexpensive.

New builds in the growth corridors are the most straightforward jobs. A slab poured with polishing in mind, an empty house and unobstructed access let a crew work efficiently through the grit sequence without working around furniture or occupants. Coordination with the builder is the main variable. Getting the polisher involved before the slab is poured is the single best thing you can do.

Renovation work in established suburbs is where costs vary most. Removing old floor coverings, dealing with decades of adhesive, working around existing walls and joinery, and grinding in an occupied house all add time, and the slab underneath is an unknown until the coverings come up. Expect a provisional allowance for remedial work. A fixed price given before lifting the carpet is optimistic.

Access for equipment is a real consideration on some Perth properties. Planetary grinders and extraction units are heavy and bulky, and upper floors, narrow side access or apartment buildings all complicate getting them in position. Mention level changes and access when requesting a quote. It affects the machinery they can bring.

Regional WA Costs

Regional polishing is dominated by travel and equipment logistics. The specialised machinery lives in Perth for the most part, so a country job means transporting a crew and their gear, and that mobilisation is a fixed cost spread across whatever area you are having done, which makes small regional jobs disproportionately expensive. Larger areas absorb it far better. Find out what area makes the trip worthwhile. Repolishing is far cheaper than the original job and far less disruptive.

The South West has genuine local capacity and prices better than distance alone suggests. Busselton, Dunsborough and Margaret River see enough new residential construction to support operators based in the region, which removes the Perth mobilisation from the equation. Ask about locally based operators before anyone else. They will usually beat a metropolitan crew travelling down.

Coordinating with other work makes regional jobs viable. Where a crew is travelling, doing the house, the garage and any outbuilding in one visit spreads the mobilisation across a much larger area and brings the rate closer to metropolitan levels. Roll every area into a single engagement. Splitting it across visits is how country jobs become expensive.

Timing flexibility helps regionally more than in Perth. Operators travelling to a region will often schedule several jobs into one trip, so being flexible about dates can put you into an existing run instead of triggering a dedicated trip. See whether they have other work booked nearby. It can change the quote meaningfully. Metropolitan crews cover the whole Perth basin without much rate variation.

What to Look Out For

Establish which process the quote is for, because grind and seal and mechanical polishing are sold under the same name and are not the same product. Grind and seal levels the surface then applies a coating that provides the gloss, and that coating wears at doorways and eventually needs stripping and recoating. Mechanical polishing grinds and densifies the concrete itself so the finish is the concrete, with nothing to peel and a light repolish available decades later. The upfront difference is significant and the whole of life difference usually runs the other way.

Get the slab assessed on site before accepting any price. Suitability depends on cover over the reinforcement, flatness, the extent of previous patching, and what adhesive or coating has to come off first, and none of that can be judged from a photograph. Remedial work runs $20 to $60 a square metre and is the item most often underestimated sight unseen. On a renovation the slab is an unknown until the floor coverings come up, so expect a provisional allowance instead of a firm figure.

Ask for test patches at each exposure level on your own slab. Cream, salt and pepper and full aggregate look completely different, and what shows depends on the aggregate in your particular pour rather than on a showroom sample from someone else's concrete. Test patches cost very little and remove nearly all the guesswork. They also reveal whether your slab will expose evenly, which is the risk that no amount of skill fully compensates for.

Confirm the grit sequence and that a densifier is included at the correct stage. Each pass removes the scratch pattern left by the previous one, so skipping a grit leaves marks that later passes cannot lift, and this is the most common shortcut in cheap work. A densifier applied at the wrong point in the sequence is largely wasted, and a floor that dusts underfoot afterwards is telling you it was never done properly. Establish what grit the floor finishes at as well.

Check how dust will be controlled before anyone starts grinding. Respirable crystalline silica causes irreversible lung disease and the exposure standard has been tightened nationally, so industrial extraction with proper filtration, or wet grinding with contained slurry, is the expected practice, not a shop vacuum. This protects your household as much as the crew. A quote that says nothing about dust control from an operator who cannot explain their system is one to set aside.

What to Look for in a Quote in WA

A polished concrete quote should name the process, the exposure level, the finishing grit, whether a densifier and stain guard are included, and what remedial preparation is allowed for. It should say how joints and existing cracks will be treated, how edges will be finished, and what dust control will be used. Settle what happens if the slab proves worse than expected once coverings come up. When two rates look alike, the gap is nearly always the process quoted and what was allowed for preparation.

Brief every polisher on the same basis. The area, what is currently on the floor, the age and history of the slab, whether the house is occupied, access for equipment and the exposure and gloss you want all shape the figure, and a quote given without seeing the slab is an estimate. Photographs help but do not substitute for an inspection. Two quotes for different processes are not comparable at any price.

Walk on a floor they polished several years ago. A freshly polished floor looks impressive regardless of who did it, whereas one that has taken years of traffic shows whether the grit sequence was completed, whether the densifier did its job and how the edges have held up. Look at the walkways and the perimeter. Ten minutes on an older floor beats any photograph or showroom sample. South West operators frequently service Bunbury through to Margaret River.

Settle the process, the slab assessment, the exposure and the dust control before anyone starts. Confirm which product you are buying, have the slab inspected and test patches ground, choose exposure and gloss from those patches, and establish how the dust will be handled. Where the slab is yet to be poured, concreting services covers getting the specification right first. With those four agreed, a polished floor lasts decades.
