Builders clean cost per m² in Adelaide (2026): fit-outs, new builds, venues and what moves the rate
What a builders clean costs per square metre in Adelaide in 2026: simple fit-outs, commercial and education new builds, hospitality and clinical finishes, variations by the hour, and what drives the rate.
A commercial builders clean in Adelaide in 2026 typically costs $4 to $5 per square metre for a simple office fit-out, $6 to $7 per square metre for a standard commercial or education new build, and $8 to $16 per square metre (typically around $11) for hospitality, clinical and other high-detail finishes. Partial-scope work on light industrial sheds, where only the offices, amenities and slab need attention, runs $0.75 to $1.50 per square metre over the whole footprint. Variations and extra attendances are charged by the hour at $70 to $90 per cleaner hour. Most contractors quote a minimum job fee of around $450 for small wet-area refurbishments.

Builders clean rates in Adelaide by building type
Per-square-metre rates are the quickest way to sanity-check a builders clean quote, as long as the square metres and the scope are the same. The ranges below are for a final clean to handover standard (rough clean, fine clean and a touch-up before practical completion) on a commercial site with normal access.
| Building type | Typical $ per m² | What sets the rate |
|---|---|---|
| Simple commercial fit-out (open-plan office, carpet tile, plasterboard, one kitchen and washrooms) | $4 to $5 | Low fixture count, standard finishes, single level |
| Standard commercial or education new build (offices, classrooms, admin, amenities blocks) | $6 to $7 | More washrooms per m², mixed floor finishes, glazing, external paving |
| Hospitality and high-detail venues (pubs, restaurants, hotels, fitted bars) | $8 to $16, typically $11 | Joinery, tiled kitchens and bars, feature finishes, tight handover windows |
| Clinical and medical (GP, dental, specialist, laboratories) | $8 to $11 | Sealed floors, clinical sinks, high fixture count, infection-control standard |
| Light industrial, partial scope (offices, amenities, slab sweep, docks) | $0.75 to $1.50 on the whole footprint | Most of the floor is a slab; the rate is driven by the office and amenities pod |
| Wet-area only refurbishment (changerooms, showers, toilet blocks) | Per room, $450 minimum job | Tiled area, grout condition, acid-wash allowance |
These are market ranges for Adelaide. Sydney and Melbourne sit roughly 10 percent higher on both the per-square-metre rates and the hourly rate for variations. A builders clean is priced from the drawings and the finishes schedule, so the number on the quote should trace back to a floor area and a list of what is in each zone. The builders cleaning page covers what the three stages include.
What moves a builders clean price
Fixture density. A square metre of open-plan office takes a few minutes. A square metre of washroom with full-height tiling, partitions, mirrors and three fixtures takes several times that. Two buildings of the same floor area can be a long way apart in hours because one has eight toilet blocks and the other has two.
Finishes and how they must be treated. New finishes come with the manufacturer’s cleaning instructions, and a contractor who ignores them can void a warranty. Polished concrete, epoxy, sports vinyl, timber, stone and powder-coated joinery each need their own method and chemistry. High-detail finishes add hours because the work is slower and the checking is stricter.
Glazing. Internal glass, shopfronts and ground-floor external glass are usually in the price. Glass above reach is either done from a lift or excluded. High-rise external glass is specialist work and is not part of a standard builders clean.
Site condition at hand-over to the cleaner. If trades are still on site, protective film is still on, or the floors are under a layer of grinding dust, the fine clean takes longer or has to be done twice. Most quotes assume the site is handed over trade-complete with rubbish removed; anything else is a variation.
Access and programme. Multi-storey buildings without lifts, sites with induction and permit requirements, night or weekend windows, and a handover date brought forward all add cost. A clean that must be done in two nights instead of five days needs a bigger crew and costs more per hour.
Wet areas. Tiled changerooms and shower blocks are the most under-priced part of a builders clean. Full-height tiling, grout haze from the tiler, and cement splash on fixtures need an acid wash and neutralise before the final clean. A sensible quote includes one acid-wash pass; heavily cemented grout that needs a second pass is a variation.
What is usually in a builders clean quote, and what is not
- In: removal of protective film and labels, dust removal from every surface including the tops of door frames and ductwork within reach, washing of walls and joinery as the finish allows, internal glass both sides, washrooms and kitchens to a sanitised standard, floors vacuumed, mopped, scrubbed or sealed as the finish requires, external paving swept and pressure cleaned at ground level, and a photographed walk at the start and at sign-off.
- Usually extra: rubbish and skip bins, removal of construction waste, external glass above ground level, paint and render removal beyond a light spot clean, floor strip and seal where the builder has not sealed, silicone and adhesive removal, and return visits after other trades have been back in.
- Before the first day: SWMS, site induction, certificate of currency, and the asbestos register read on refurbishment work. Identified materials are never disturbed by the cleaner.
Hourly variations
Anything outside the quoted scope is charged by the hour. In 2026 the published commercial rate for variable-scope work is $70 to $90 per cleaner hour in the eastern states; Adelaide sits at the lower end of that band. Variations are the best-value work for the contractor because the crew is already on site and the access is sorted, so a contractor who is cheap on the base rate and expensive on variations is a common pattern. Ask for the variation rate in writing with the quote, and ask what the minimum charge for a return visit is.
How to check a builders clean quote
- Divide the price by the floor area on the drawings. If it falls below the band for the building type, ask what has been left out or how many hours have been allowed.
- Check that the finishes schedule has been read. A quote that does not mention the floor finishes has not been costed properly.
- Ask for the crew size and the number of days. Area divided by hours is the real test: a fine clean runs at roughly 60 to 120 m² per cleaner hour on open floors and far less in washrooms.
- Look for the two photographed walks and same-day sign-off. Without them, defects found at practical completion become an argument about who left them.
- Confirm the variation rate, the minimum return charge, and what happens if the handover date moves.
If you have the drawings, a scope and a date, a fixed, itemised price can usually be issued from them without a site visit. If the site is a refurbishment or the finishes are unusual, a site walk-through first will give a firmer number.
FAQs
For routine cleaning once the building is occupied, see the 2026 commercial cleaning cost guide.
How much does a builders clean cost for a 500 m² office fit-out in Adelaide?
At $4 to $5 per square metre, $2,000 to $2,500 plus GST for a standard fit-out with one kitchen and washrooms, trade-complete and single level. More washrooms, feature finishes or a two-night window push it higher.
Why is a pub or restaurant builders clean so much dearer per square metre?
Joinery, tiled kitchens, bars, feature lighting and fitted furniture all add surfaces and slow the work. A venue also usually opens on a fixed date, so the clean is done in a short window with a larger crew.
Is pressure cleaning of external paving included?
Ground-level paving and entries are usually in. Car parks, large hardstand areas and anything needing a ride-on sweeper are priced separately.
What is a rough clean versus a fine clean?
The rough clean removes the bulk of the construction dust, packaging and debris once the trades are out. The fine clean brings every surface to handover standard. The touch-up is a short visit after defect works to clean up what the trades disturbed.
Can a builders clean be quoted without a site visit?
Yes, for new builds with drawings and a finishes schedule. Refurbishments, heritage buildings and sites with asbestos registers should be walked first.
