Definition
Post-Construction Cleaning — Post-construction cleaning (often called after builders cleaning) is the specialist clean done once trades have finished, removing construction dust, plaster, paint, sealant residues and protective film from a renovated space.
What post-construction cleaning covers
- HEPA vacuuming for fine construction dust
- Removal of paint splashes from glass and tiles
- Plaster and silicone sealant residue cleaning
- Protective film and stickers removed
- All surfaces wiped, including ceilings if needed
- Final fit fittings, switches and handles polished
What post-construction cleaning costs
Post-construction cleaning costs £100 to £500 or more depending on the project, at £25 per hour. A single-room refurb is 4 to 6 hours, a kitchen replacement 6 to 9 hours, and a full house renovation 16 to 24 hours or more. It costs more than a deep clean of the same size because construction dust keeps resettling and has to be removed in passes.
- Single-room refurb: 4 to 6 hours, £100 to £150
- Bathroom replacement: 5 to 7 hours, £125 to £175
- Kitchen replacement: 6 to 9 hours, £150 to £225
- Single-storey extension: 8 to 14 hours, £200 to £350
- Full house renovation: 16 to 24 hours or more, from £400, always two visits
Post-construction cleaning vs a deep clean
People book a deep clean after building work and are disappointed. The two jobs remove different things, in a different order, with different equipment.
| Post-construction clean | Deep clean | |
|---|---|---|
| Removes | Plaster and MDF dust, paint, silicone, adhesive, protective film | Grease, limescale, soap scum, household dirt |
| Order of work | Dry removal first, wet clean second, or the dust turns to paste | Wet clean throughout, top to bottom |
| Equipment | HEPA vacuum, blades, filters changed mid-job | Standard cleaning kit |
| Visits | Usually two, with 24 to 48 hours for dust to resettle | One |
| Typical cost | £100 to £500+, priced by project | £125 to £250, priced by property size |
How long post-construction cleaning takes
Construction dust is extremely fine and stays airborne for hours. That is why the job runs in passes rather than room by room, and why a single visit rarely finishes it.
| Stage | Typical time | What happens |
|---|---|---|
| First pass, dry removal | 2 to 4 hours | HEPA vacuuming of ceilings, walls, ledges and floors. Nothing wet yet, or the dust turns to paste. |
| Film, stickers and residue | 1 to 3 hours | Protective film, labels, silicone smears and plaster splashes lifted off glass, tiles and units. |
| Second pass, wet clean | 3 to 5 hours | Every surface washed down, including inside new units, sockets and window tracks. |
| Settle period | 24 to 48 hours | Remaining airborne dust drops out. Nothing you do during this window stays clean. |
| Sparkle visit | 2 to 3 hours | Final polish of glass, taps, mirrors and floors, timed for handover or move-in day. |
Who books post-construction cleaning
Homeowners
Book after an extension, loft or refit, usually once the builder has done a rough tidy but before furniture goes back in.
Builders and contractors
Book it as the last line on the job so the property can be handed over finished rather than swept.
Property developers
Book rough clean plus sparkle clean as two separate visits, tied to viewing or completion dates.
Landlords
Book after works between tenancies, often combined with a pre-tenancy clean so the property is inventory-ready.
Post-construction cleaning checklist
If you are tackling it yourself, the order matters more than the products. Working wet-first is the mistake that costs people a whole weekend.
- 1Wear a dust mask. Plaster and MDF dust is an irritant, and you will stir up a lot of it.
- 2Change or clean your vacuum filter first, then vacuum ceilings and walls before floors.
- 3Do all dry dust removal before any water touches a surface.
- 4Peel protective film off units, glass and appliances before washing anything down.
- 5Scrape paint and plaster off glass with a blade held flat, working on a wet surface.
- 6Clean inside every new cupboard and drawer, including the runners.
- 7Vacuum window tracks, socket faces and radiator fins, which hold dust for months.
- 8Wash floors last, then leave it a day or two and expect to wipe everything once more.
When post-construction cleaning is needed
- 1After a renovation or extension
Standard cleaning will not handle construction dust or fine residues.
- 2New build handover
Developers and self-builders use it to present the home as truly finished.
- 3Kitchen or bathroom refit
Tackles silicone, grout dust and protective film around new units.
Post-Construction Cleaning: common questions
How much does after construction cleaning cost?
Post-construction cleaning costs £100 to £500 or more at £25 per hour, depending on the project rather than the property size. A single-room refurb is £100 to £150, a kitchen replacement £150 to £225, an extension £200 to £350, and a full house renovation £400 upwards across two visits.
Why does builders dust keep coming back?
Construction dust particles are fine enough to stay airborne for hours and keep dropping out of the air for 24 to 48 hours after the work stops. That is why a single clean never finishes the job, and why the last visit should be timed for after the settle period rather than straight after the trades leave.
Should you clean builders dust wet or dry first?
Dry first, always. Vacuum ceilings, walls, ledges and floors with a HEPA filter before any water touches a surface. Plaster and MDF dust turns to a paste when wet, which spreads it across the surface and makes it much harder to remove.
Is after builders cleaning the same as post-construction cleaning?
Yes. They are two names for the same job: removing construction dust, plaster, paint splashes, sealant residue and protective film once trades have finished. Larger developments sometimes split it into a rough clean and a final sparkle clean, but both fall under the same service.
Who is responsible for cleaning after building work?
Unless your contract says otherwise, the builder is responsible for removing waste and leaving the site broom-swept, and the homeowner pays for the detailed clean that makes the space liveable. Check the contract before the work starts, because it is far cheaper to agree than to argue about afterwards.
