$10–$90/m² Sydney Concrete Grinding: Strata Costs, SafeWork NSW Rules
Concrete grinding in Sydney typically costs between $10 and $90 per square metre, depending on coating removal, surface condition and dust control requirements. Most contractors also charge a minimum job fee for small areas. Final pricing depends on a site inspection, since access, slab condition and compliance needs all shift the quote.
TL;DR:
- Most concrete grinding jobs in Sydney cost between $10 and $90 per square meter, depending on coating removal, surface condition, and dust control needs.
- A site inspection and a detailed written quote are essential, especially to confirm dust extraction class and avoid compliance risks.
- Heavy-duty polishing and resurfacing, including sealers and finishes, can range from $55 to $160 per square meter, with higher costs for asbestos testing and adhesive removal.
- Contractors charging unusually low mobilization fees or refusing to detail dust control methods likely cut corners, increasing potential costs later.
- Equipment hire costs around $500 per day, but compliance with dust safety regulations remains crucial whether hiring equipment or hiring professionals.

Typical Sydney price ranges explained
Pricing moves in bands, and knowing which band your job falls into helps you budget before a contractor even walks the site. A simple grind on a clean, coating-free slab sits at the lower end of the $10 to $90 per square metre range reported for Sydney jobs, since it usually needs only one or two passes and standard dust extraction.
Grind and seal work costs more because it adds a protective topcoat and finer surface preparation. Industry pricing guides put grind-and-seal jobs at roughly $55 to $90 per square metre, with Sydney often landing at the higher end due to labour rates and inner city access constraints. Adhesive or glue removal, common in office strip-outs and warehouse end-of-lease jobs, adds time because old carpet glue, tile adhesive or epoxy coatings need multiple mechanical passes before the slab is level.
Heavy commercial preparation and mechanical polishing sit at the top of the scale, with polishing work commonly quoted around $85 to $160 per square metre for retail or showroom floors that need a high-gloss finish.
A few things shape what’s included in each band:
- Dust extraction method (standard versus H-class) affects both price and compliance.
- Number of grinding passes required depends on coating thickness and slab hardness.
- Edge work and detailing around columns or skirting often carries a separate line item.
- Sealer application, where requested, is priced on top of the base grinding rate.
All figures above are typically quoted exclusive of GST unless stated otherwise, and no contractor should commit to a final number without seeing the site first.
How to get an accurate written quote in Sydney
A reliable quote starts with someone walking the actual floor, not a phone estimate. Before you sign anything, ask for a written, line-item breakdown that separates labour, equipment, dust control and waste disposal.
Confirm the dust extraction method in writing. SafeWork NSW’s silica safety checklist requires H-class or M-class vacuum extraction or water suppression on any job generating silica dust, and uncontrolled dust can trigger stop-work notices or on-the-spot fines. If a contractor can’t name their extraction class, treat that as a warning sign.
Pro Tip: Ask every quote to state its dust extraction class (H or M) in writing. A contractor who can’t answer this question on the spot is a compliance risk, not just a pricing one.
Before accepting a quote, check for:
- A site inspection and written, itemised quote rather than a verbal estimate.
- Confirmation of H-class or M-class dust extraction matching SafeWork NSW guidance.
- An asbestos identification statement, especially in buildings constructed before the mid-1980s.
- Clear terms for slurry disposal, waste removal and recycling.
- Proof of insurance and WHS accreditation.
Unusually low mobilisation fees, no mention of dust extraction, or a refusal to put insurance details in writing are the clearest signs a quote is cutting corners that cost more later.
Sydney City Rubbish: local grinding services, dust control and compliant waste removal
We handle concrete grinding alongside the waste removal that every grinding job leaves behind, which means one booking covers the floor preparation and the slurry, offcuts and old coatings that come off it. Our teams work to dust control standards aligned with SafeWork NSW silica guidance, and we coordinate directly with building management so access and out-of-hours scheduling don’t become your problem to solve.
For commercial and strata clients, that bundling matters: a grinding contractor who leaves slurry and debris behind just shifts the cost onto a second booking. We also provide disposal options aimed at supporting environmentally conscious waste handling through registered recycling partners.
What we cover on a typical Sydney grinding and clean-up job:
- Concrete grinding, cutting and core drilling for commercial and construction sites.
- Professional dust control during grinding to manage silica exposure.
- Slurry and debris removal, including sorting for recycling where possible.
- Construction waste management for the broader strip-out or fit-out project.
If you’re budgeting a grinding job in Sydney, request a free on-site assessment and quick quote for commercial waste removal and we’ll give you a written breakdown before any work starts.
FAQ
How much is concrete grinding per m2 in Sydney?
Simple grinding typically costs $10 to $90 per square metre, while coating removal or heavier preparation pushes the rate toward $55 to $90 per square metre. The exact figure depends on slab condition, access and the dust control method required on site.
How much do contractors charge to grind concrete?
Most Sydney contractors price grinding per square metre within the $10 to $90 range, but small jobs usually carry a separate minimum charge to cover mobilisation and equipment setup. A written quote following a site visit is the only reliable way to confirm your actual cost.
How much does it cost to resurface a concrete surface in Sydney?
Resurfacing that includes grinding and sealing generally falls in the $55 to $90 per square metre band, with high-gloss mechanical polishing running higher, around $85 to $160 per square metre. Costs rise further if asbestos testing or adhesive removal is needed first.
How much does it cost to hire a concrete grinder in Sydney?
Equipment hire suppliers commonly list grinder and dust extractor packages at around $500 per day including GST, with discounts for multi-day hire. DIY hire still requires compliance with SafeWork NSW dust control rules, so factor that into the total cost before choosing between hiring equipment and booking a professional crew.
