Quick answer
Most builders cleans in Australia are quoted per square metre. Published 2026 industry price guides put a full handover clean including windows at roughly $8 to $12 per square metre, so a 250 m² home typically lands somewhere around $2,000 to $2,400. Smaller jobs and defect or variation work are often charged hourly, commonly $50 to $90 per hour. The final number comes down to size, how much debris the trades left, how much glass there is, and which stage of clean you need.
“What does a builders clean cost?” is the first question most builders ask, and the honest answer is that two quotes for the same site can differ by thousands — usually because they’re not quoting the same scope. Here’s how pricing actually works, what the market ranges look like, and how to compare quotes properly.
How builders cleans are priced
There are three pricing models you’ll come across, and knowing which one you’re being quoted matters more than the headline number.
- Per square metre — the standard for full handover cleans. Predictable, easy to compare, and the model most commercial builders prefer because it scales with the job.
- Hourly — common on small jobs, single rooms, defect rectification and variation work where the scope isn’t fixed.
- Fixed price per project — quoted from your floor plans and site photos. Best for multi-stage jobs and anything where you need budget certainty.
A per-square-metre rate only means something once you know what’s inside it. Windows, in particular, are the single biggest swing factor — a rate that excludes glass will always look cheaper than one that includes it.
What a builders clean costs in Australia: typical ranges
The figures below are the ranges commonly published across Australian industry price guides for 2026. Treat them as a ballpark for budgeting, not a quote — every site is different.
| What you’re pricing | Typical Australian range (2026) |
|---|---|
| Full handover clean including windows, per m² | ~$8 – $12 per m² |
| Project home / standard finishes | ~$8 – $9 per m² |
| Custom home / premium finishes | ~$10 – $12 per m² |
| Hourly rate (small jobs, defect and variation work) | ~$50 – $90 per hour |
| Small post-renovation clean (e.g. three-bedroom) | ~$400 – $800 |
| 250 m² project home, full handover clean | ~$2,000 – $2,400 |
Rates sit fairly close across Sydney, Melbourne and Brisbane. Where you’ll see real variation isn’t the city — it’s the condition of the site and the finishes involved.
Six things that change the price
1. Size
Floor area is the base of every quote, but it isn’t the whole story. High or vaulted ceilings add labour and equipment without adding a single square metre to the plan.
2. How much mess the trades left
A site that’s been broom-swept as the trades finished is a different job from one buried in plaster dust, offcuts and packaging. If your crews leave it tidy, your clean gets cheaper — that’s the easiest lever a builder controls.
3. Glass
Windows are the slowest part of any final clean. A floor-to-ceiling glass apartment costs meaningfully more than the same floor area with standard windows, and paint overspray or silicone on glass adds more again.
4. Which stage — and how many
A rough builders clean costs less than a detailed final clean. Many projects need both, plus a touch-up before handover. Three visits cost more than one, but they’re almost always cheaper than re-cleaning a site that got contaminated because everything was left to the last day. Our guide on builders clean vs final clean vs bond clean explains which you actually need.
5. Finishes and materials
Stone benchtops, raw or oiled timber, tinted glass and powder-coated surfaces all need specific products and slower, more careful work. Premium finishes are the main reason custom homes sit at the top of the per-metre range.
6. Access and timing
Lift bookings, restricted parking, high-rise levels, after-hours or weekend work and no power or water on site all add cost. So does a compressed deadline — same job, more crew.
Why the cheapest quote often isn’t the cheapest job
When one quote comes in dramatically lower, it’s rarely because that company is more efficient. Usually something is missing from the scope. Before you compare prices, check each quote answers all of these:
- Are windows included — inside, outside, frames and tracks?
- Is it one clean, or a rough plus a final plus a touch-up?
- Is debris removal and disposal included, or billed separately?
- Does it cover inside cupboards, robes and drawers?
- Are they using HEPA extraction, and are they insured for construction sites?
- What happens if the builder isn’t happy at walkthrough — is a return visit included?
An under-quoted clean tends to cost more in the end, because a rushed or incomplete finish turns into defect-list items and a delayed handover. That’s exactly the scenario covered in the #1 reason post-construction cleans get delayed.
How to bring the cost down
Most of the levers sit with the builder, not the cleaner:
- Have your trades clear their own debris. Removing bulk waste before the cleaners arrive is the single biggest saving.
- Book once the last trade is out. Cleaning around active work means paying for the same room twice.
- Give a few days’ notice, not a few hours. Rush jobs need extra crew.
- Make sure power and water are on. No utilities means downtime you’re paying for.
- Bundle multiple stages or multiple units into one engagement rather than quoting them piecemeal.
- Use the same checklist every time so nothing gets missed and re-cleaned. Ours is here: the builders clean checklist.
Getting an accurate quote quickly
You don’t need to wait around for someone to walk the site. We quote from your floor plans and a few photos, which is usually faster and more accurate than a walkthrough — the plans give us exact areas, and the photos show us the actual condition and finishes.
Send through:
- Floor plans, or the total floor area in square metres
- A handful of photos showing the current state of the site
- The handover date and which stages you need
- Anything unusual — high ceilings, extensive glass, delicate finishes, restricted access
With that, you’ll have a fixed price back quickly, itemised so you can see exactly what’s included.
Frequently Asked Questions
Published 2026 industry price guides put a full handover clean including windows at roughly $8 to $12 per square metre. A 250 m² home typically lands around $2,000 to $2,400. Smaller jobs are often charged hourly, commonly $50 to $90 per hour.
Full handover cleans are usually quoted per square metre, because it’s predictable and easy to compare. Hourly rates are more common on small jobs, single rooms, and defect or variation work where the scope isn’t fixed.
Almost always because they’re not quoting the same scope. The biggest differences are whether windows are included, whether it’s one clean or a rough plus final plus touch-up, and whether debris removal and disposal are in the price.
Not always — and it’s the single biggest swing factor in a quote, because glass is the slowest part of any final clean. Always check whether the rate covers glass inside and out, plus frames and tracks.
Have your trades clear their own debris, book the clean once the last trade is off site, give a few days’ notice rather than a few hours, and make sure power and water are connected.
