On a single home, the builders clean is one booking. On an apartment building or a townhouse development it becomes a schedule: units finish at different times, trades move back and forth, common areas stay busy until the very end, and handovers can run over days or weeks. Most problems on these projects are not about cleaning quality. They come from a cleaner arriving at a unit that is not ready, or a clean unit being walked through by the next trade.
This guide is for site managers and project coordinators planning the cleaning on multi-unit projects. For what each clean covers, see what a builders final clean includes.
Release units in batches
Decide early how units will be handed to the cleaners. Common options are:
- By floor or level, when trades work up or down the building
- By building or block, on townhouse developments
- By handover group, when the client or buyers take units in stages
A batch is easier to plan than single units. The cleaning team can work through a set of units in one visit, and the site only has to arrange access once. Tell the cleaner the release order as soon as you know it, and update it when the programme changes.
Agree what “ready for cleaning” means
A unit released too early costs a wasted visit or a second clean. Before a unit goes on the list, check:
- The last trade in that unit has finished, including appliances, fittings and any return visits already booked
- Rubbish, offcuts and packaging are out, because building waste removal is not part of builders cleaning
- Floor protection is lifted, or it is agreed who lifts it and when
- Power and water are on
- Keys or access are arranged for that unit
Putting these points into the release notice, rather than just “Unit 4 ready”, saves arguments later.
Keep one unit register
A simple shared register, in a spreadsheet or your project software, stops units being missed or cleaned twice. Use one row per unit:
| Column | What to record |
|---|---|
| Unit | Number and level |
| Stages | Rough, final or touch-up — whichever that unit needs |
| Ready from | The date the unit is released for cleaning |
| Cleaned | The date of each stage |
| Checked | Who walked the unit afterwards, and when |
| Touch-up | Areas a trade has been back to since the clean |
| Handover | The date the unit is handed over |
Share the register with the cleaning company, or ask them to report against it after each visit, so both sides are looking at the same list.
Plan stages per unit, not per project
Not every unit needs every stage. A unit the trades finished early may need a rough clean, a final clean and a touch-up; one that finishes just before handover may only need a final clean. Our guide to rough cleaning vs final builders cleaning explains when each stage helps. When builders cleans are priced per stage or per unit, the register also becomes the record of what has been done and what is still to come.
Leave common areas until last
Lobbies, corridors, stairwells, car parks and bin rooms carry trade traffic and deliveries until the end of the project, so cleaning them early is usually wasted. Plan them as a separate item:
- schedule them after the last deliveries and trade movements
- agree whether they are in the cleaning scope at all, and list them separately in the quote
- plan anything needing work at heights, such as high glazing in a lobby or a void, with the relevant trade, because it is not part of builders cleaning
Protect units once they are clean
On a multi-unit job, a common cause of a second clean is a trade going back into a unit after it has been cleaned. A few habits help:
- mark cleaned units clearly on the register and, where practical, on the door
- keep cleaned units locked where you can, and record who goes in
- ask trades returning for defects to protect the floors and tell the site manager which unit they worked in
- book a touch-up for that unit instead of a full re-clean
Inspections and handover
Walk each unit against the register before handover, and keep cleaning items separate from defects such as chips, scratches or paint splashes, which go to the relevant trade rather than the cleaner. Our new build handover checklist has a room-by-room check you can use for each unit. Where units are handed over in groups, a short touch-up just before each group is often more useful than one large clean at the very end.
Communication that keeps it moving
- One site contact for the cleaning team, with a back-up
- A look-ahead, weekly or fortnightly, of the units expected to be released
- Induction and site rules sent before the first visit
- A short report after each visit naming the units cleaned and anything that stopped work, such as a locked door or a trade still working
Getting a quote for a multi-unit project
Our builders cleaning covers townhouse and unit developments. Each stage is priced and booked separately, quoted per stage or per unit after we see the plans or the site. We confirm prices in writing before starting, and changes on site are only booked after you approve them. Send the site location, the number of units, the stages you need and the handover dates through the builders quote request, with your induction requirements, and upload plans, a unit schedule or the programme if you have them, as PDF, Word (.docx) or photo files.
