Quick answer
A builders clean on an apartment building isn’t a bigger version of a house clean. Four things change it: access and lift logistics, staged handover floor by floor, common areas that need their own scope, and keeping finished units clean while trades still work above them. Units are normally priced per unit at volume rates, with common areas quoted separately and cleaned just before each inspection or settlement.
Most guidance on builders cleans is written for a single house. Multi-unit is a different job, and the differences are mostly logistical rather than technical — which is exactly why they get underestimated at tender.
Why apartments aren’t just bigger houses
The cleaning method inside any single apartment is much the same as a house: top-down, back-to-front, HEPA extraction, glass last. Scale that to forty units across twelve levels and the work stops being about technique and starts being about sequencing and access.
On a house, the crew arrives, cleans, leaves. On a tower, they’re working around a lift booking, a loading dock slot, other trades still finishing levels above, and a settlement calendar that means level three has to be perfect three weeks before level eleven exists.
The four things that actually change
1. Access and lift logistics
Everything — crew, equipment, water, waste — moves vertically through a shared bottleneck. A single lift booking can decide whether a crew does two levels in a day or one.
What matters in practice: confirmed lift or hoist windows, loading dock access, parking for the crew, security and site inductions, and where waste goes. Access difficulty is one of the recognised cost drivers on multi-unit work, alongside floor area, room count and contamination level — so vague access arrangements cost real money.
2. Staged handover
Apartments almost never hand over in one go. Levels are released progressively against inspection and settlement dates, which means the clean isn’t one event — it’s a rolling programme.
The principle that works is just-in-time: each section is cleaned immediately before it’s needed for inspection or settlement, not weeks ahead. Clean level four in advance and you’ll clean it again, because dust from levels above will find it. Our guide to scheduling each stage of a handover clean covers the underlying sequence.
3. Common areas are their own project
This is the most commonly under-scoped part of a multi-unit clean. Lobbies, corridors, stairwells, lift cars, bin rooms, basement car parks, plant rooms and amenity spaces are not covered by a per-unit rate, and several of them stay dirty longer than the apartments because trades keep using them.
Common areas also tend to be the first thing a buyer sees at settlement. A spotless apartment reached through a dusty corridor still reads as unfinished.
4. Protecting what’s already finished
On a house, once the clean is done the building is done. On a tower, level three is finished while level eleven is still being fixed out — so re-contamination isn’t a risk, it’s a certainty unless it’s managed.
That means sealing completed levels, controlling foot traffic through finished corridors, and keeping the air conditioning off until the last clean is done. Commissioning the system early pulls settled construction dust out of the risers and redistributes it across every level you’ve already paid to clean.
How multi-unit cleans are priced
Three components, and it’s worth insisting a quote separates them:
- Per unit, at volume rates. Repetition creates genuine efficiency — identical layouts, the same materials, a crew that learns the apartment by the fifth one. Per-unit cost on a large development should be meaningfully lower than the same apartment cleaned standalone.
- Common areas, quoted separately. By area and by stage, because they’ll usually need more than one pass.
- Access and staging loadings. Restricted lift windows, after-hours work, high-rise levels and split mobilisations all carry real cost. A quote that ignores them will find them later as a variation.
The underlying drivers are the same as any builders clean — floor area, glass, debris load, finishes — which we break down in what a builders clean costs in Australia. Multi-unit just adds the logistics layer on top.
A sequence that works
- Rough clean by level as each floor comes off fixout, so debris never accumulates.
- Final clean just-in-time — booked against the inspection or settlement date for that release, not the programme’s optimistic version of it.
- Seal and protect completed levels; restrict trade traffic through finished corridors.
- Common areas last within each release, since they carry the traffic that dirties them.
- Touch-up before each settlement batch, after defect work is closed out.
Get the order wrong and you pay for the same square metres twice — which is the pattern behind most post-construction cleaning delays.
What to specify when you tender it
- Unit count, typical layouts and floor areas — ideally the drawings
- Common areas listed explicitly, including basement and plant rooms
- The release schedule and settlement dates, so cleaning can be staged against them
- Lift and dock availability, and any after-hours restrictions
- Whether glazing is internal only, or external as well
- The standard being worked to — attaching a room-by-room checklist settles this before it becomes an argument
Frequently Asked Questions
The cleaning method inside each unit is similar, but the job is governed by logistics — lift and dock access, staged handover by level, separately scoped common areas, and keeping finished levels clean while trades still work above them.
In three parts: per unit at volume rates, common areas quoted separately by area and stage, and loadings for access and staging. Insist a quote separates them, or the common areas end up as a variation.
Just in time — immediately before that release is needed for inspection or settlement. Cleaning a level weeks early means cleaning it twice, because dust from the levels above will find it.
Common areas. Lobbies, corridors, stairwells, lift cars, bin rooms, basement car parks and plant rooms aren’t covered by a per-unit rate, and they stay dirty longer because trades keep using them.
Commissioning it before the final clean pulls settled construction dust out of the risers and redistributes it across every level you’ve already paid to clean.
