The quickest way to clean after builders is to work top to bottom and room by room. Clear debris first, then remove dust with a damp cloth or a suitable extraction vacuum, never a dry brush. Then clean fixtures, floors and glass, and finish with an inspection in good light. The checklist below follows that order, so nothing gets cleaned twice.
It covers extensions, kitchen and bathroom refits, loft conversions and new-build handovers. If you would rather hand the job to a professional team, there is a short section on that too.
TL;DR
- Work from the ceiling down and from the room furthest from the front door towards the exit, so dust never settles on surfaces you have finished.
- Do not dry sweep or use compressed air. HSE advises damping down and using an M- or H-class vacuum for fine construction dust.
- Clean in three passes: debris and protective sheeting, then dust and surfaces, then fixtures, glass and floors.
- Do a touch-up wipe a few days later, because fine dust keeps resettling after the first clean.
- If you are short on time or the dust is heavy, our after builders cleaning team can take the whole list off your hands.

What counts as a builder's clean?
A builder's clean is the basic tidy a contractor leaves behind: rubble and packaging removed, surfaces roughly wiped, floors swept. It is not the same as a full after builders clean, which removes the fine dust in cupboards, on door frames and inside fittings, and leaves the home ready to live in.
There is no single legal definition for homeowners, so agree it in writing before work starts. Ask your contractor what they will leave you with: debris removed from site, protective coverings taken up, and what they consider "clean". For context on the trade side, HMRC's guidance says internal cleaning of buildings carried out during or on completion of construction counts as a construction operation under the Construction Industry Scheme. In other words, the industry treats it as part of the building work, not an optional extra.
A useful rule: the builder's clean gets the site safe and tidy. The after builders clean is what makes the home hygienic and presentable.
What you need before you start
Gather everything first. Stopping halfway to find a bucket means walking dust through rooms you have already done.
Equipment
- A vacuum with a fine-dust filter. HSE recommends an M- or H-class extraction unit for finer material. An ordinary household vacuum can blow the finest particles back into the air.
- Microfibre cloths, plenty of them, washed or swapped often.
- Two buckets, a mop, a soft broom for damp debris, a dustpan and brush.
- A plastic scraper for paint and sealant splashes, used gently on glass and tiles.
- Heavy-duty bags for rubble, and separate bags for general waste.
- Stepladder, so you can reach ceilings, light fittings and the tops of door frames.
Protection
- Disposable gloves and eye protection.
- A dust mask rated for fine dust. HSE identifies construction dust, which may contain respirable crystalline silica, as a serious health hazard, so do not skip this on a dusty site.
- Open windows throughout, and keep children and pets out of the area.
Cleaning products
- A neutral all-purpose cleaner, a glass cleaner, a bathroom descaler suited to your surfaces, and a degreaser for the kitchen.
- Check each product on a hidden patch first, especially on natural stone, new worktops and painted finishes.
Before you clean: a safety check
Building dust is not ordinary household dust. It can contain fine mineral particles, and the way you remove it matters more than how hard you scrub.
HSE is clear on method: it says dry brushing can produce high peak silica exposures, and that breathing construction dust can cause serious, permanent lung disease. So:
- Damp down first. Lightly mist dusty surfaces and debris before moving them.
- Never dry sweep and never use compressed air or a leaf blower indoors.
- Vacuum with the right unit, then wipe with damp microfibre.
- Ventilate and keep doors to finished rooms shut.
One more point: if the work disturbed old boards, pipe lagging, textured ceilings or cement sheeting in an older property and you are unsure what they are, stop and ask your contractor or a qualified surveyor before cleaning them up. HSE guidance for weathered asbestos cement says to clean with damp rags and bag the waste, and that high-pressure jetting needs a specialist contractor. Suspected asbestos is not a DIY clean.
We cover the method in more depth in our guide on how to remove builders dust.
The after builders checklist: step by step
Work in three passes. Each pass goes top to bottom through the whole property before you start the next.
Pass 1: debris and protection
- Remove all rubble, offcuts, packaging, empty paint tins and tools from every room, the garden path and the hallway.
- Take up floor protection, dust sheets and taped plastic carefully, folding dust inwards. Bin them rather than shaking them out.
- Remove masking tape and sticky residue from frames and glass while it is still soft.
- Check the skip or waste arrangement with your builder. Disposal rules vary by council: in Kent, for example, a council legal paper treats construction waste from a home as industrial waste, so household recycling centres are not obliged to take it free. Check your own council's rules before loading the car.
Pass 2: dust and surfaces
Start high and finish low in every room.
- Ceilings, cornices and coving: vacuum with a soft brush attachment, then wipe with a barely damp cloth.
- Light fittings, extractor grilles, smoke alarms (cover or wipe the outside only) and ceiling fans.
- Walls: dust, then spot-clean marks. Do not scrub fresh paint; it can take weeks to cure fully.
- Skirting boards, door frames, architraves and the tops of doors.
- Window sills, frames and tracks. Vacuum the tracks before wiping.
- Radiators, front and back, and vents. Dust collects in the fins.
- Shelves, built-in storage and the insides of cupboards and drawers.
- Switches, sockets and door handles.
Pass 3: fixtures, glass and floors
- Windows and mirrors, inside, then the frames.
- Sanitaryware and taps (details below).
- Hard floors: vacuum, then damp mop, changing water as soon as it clouds.
- Carpets: vacuum slowly, several passes in different directions.
- Last of all, wipe door handles and the hallway, because everyone walks through them.
Room-by-room detail
Kitchen
Kitchens collect the finest dust because of the cabinets and appliances.
- Empty the cupboards if the builders left them open, and wipe the insides before restocking.
- Clean cabinet fronts, edges and handles; plaster dust hides along hinges and the top of wall units.
- Wipe worktops with a cleaner safe for the material. Fresh stone or laminate can mark if you use harsh products.
- Remove protective film from appliances, then clean the hob, extractor hood and filters.
- Clean the sink, taps and splashback, and check silicone lines for smears.
- Inside the oven: new ovens usually only need a wipe, but a renovated kitchen where the oven stayed in place may have a layer of fine dust and grease. Our oven cleaning service handles the stubborn cases.
- Vacuum and mop the floor last, including under the plinth edges where you can reach.
Bathroom
- Peel off protective film from baths, shower trays and screens as late as possible, then clean.
- Remove cement or grout haze from tiles with a product suited to your tile. Test it somewhere hidden first.
- Clean basin, toilet, bath, taps and shower fittings. Descale shower heads if the water was off for a while.
- Wipe extractor fans and grilles, then shelves, mirror and cabinet interiors.
- Check tile grout and silicone for gaps, which belong on the snagging list, not just the cleaning list.
Our bathroom deep cleaning checklist goes further on limescale and grout.
Bedrooms and living rooms
- Dust high to low: coving, light fittings, curtain poles, wardrobe tops, picture rails.
- Wipe inside built-in wardrobes and the shelves.
- Wash or air curtains and blinds; dust hides in the folds.
- Clean windows and sills, and vacuum the tracks.
- Vacuum sofas, mattresses and soft furnishings that were in the room during work. If they were not covered, professional upholstery cleaning is worth considering.
- Vacuum carpets thoroughly. Heavily dusted carpets may need professional carpet cleaning to lift the embedded fine particles.
Hallways, stairs and entrance
- Clean banisters, spindles and handrails, which collect a surprising amount of dust and fingerprints.
- Wipe skirting and each stair riser, working from the top step down.
- Clean the front door inside and out, including the frame and letterbox.
- Mop last, and then keep boots off.
Loft, garage and utility spaces
- Vacuum and damp-wipe shelves, boiler cupboard surfaces (outside the boiler only) and any exposed pipework.
- Clear leftover materials and tools, and check nothing is blocking air vents.
Outside
- Sweep paths and the patio once the debris is bagged, using a damp method if the dust is fine.
- Clean external windows, door frames and thresholds.
- Check gutters and drains near the work area for cement and plaster.
Surfaces that need extra care
| Surface | What goes wrong | Safer approach |
|---|---|---|
| Glass | Paint flecks and sealant scratch easily | Soften with a damp cloth, lift with a plastic scraper, then glass cleaner |
| Natural stone worktops | Acidic or harsh cleaners can etch or stain | Warm water and a stone-safe cleaner only |
| New laminate and gloss units | Abrasive pads leave dull scratches | Soft microfibre and mild detergent |
| Hardwood and oak | Water and grit damage the finish | Vacuum first, then barely damp mop; see care tips for oak furniture and floors |
| Stainless steel | Streaks and fingerprints | Wipe with the grain, then dry |
| Fresh paint | Marks easily for weeks | Dust gently, spot-clean only |
The final inspection: check before you sign off
Clean the home first, then inspect it, because dust and film hide defects. Use daylight where you can, plus a torch held at an angle to show scratches and uneven finishes.
Before you make the final payment, walk each room with your contractor, and note anything unfinished:
- Paint: missed patches, drips, roller marks, scuffs on skirting.
- Plastering: cracks, rough patches, nail pops.
- Doors and windows: open, close and lock every one. Check for sticking, gaps and smears on glass.
- Sockets, switches and lights: all fitted, all working, no cracked covers.
- Taps and plumbing: run every tap, flush every toilet, look for drips under sinks.
- Sealant and grout: continuous, no gaps around baths, basins and worktops.
- Flooring: no lifting edges, scratches or gaps, and a clean finish at thresholds.
- Heating: radiators warm evenly and valves work.
- Fitted units: doors align, drawers glide, handles are tight.
Take dated photos of everything you want put right and send them in writing. If a new-build developer is handling the handover, report faults through their own process, and keep copies of all your messages.
Do a second touch-up a few days later
Even a careful clean does not catch everything on day one. Fine dust stays airborne and settles slowly, so some firms recommend a short touch-up clean after final snagging work. Wipe sills, shelves, the tops of furniture and hard floors again a few days later, then leave the windows open for a time. If the builders return to fix snags, expect new dust and plan a quick re-wipe afterwards.
Once the dust is gone, look after new finishes. For furniture and flooring, the guide to caring for oak in UK homes is a good place to start.
How long does it take, and what is worth outsourcing?
How long it takes depends on the size of the property and how much dust the work produced. A small bathroom refit may be a few hours; a whole-house renovation or extension can fill several days for one person, especially with the touch-up. Plan the clean after the builders have fully finished and removed their tools, not between stages.
Sensible jobs to hand over:
- Whole-house dust removal after an extension or loft conversion.
- Ovens, carpets and upholstery that took the dust.
- Windows, frames and tracks with paint or sealant marks.
- Any job where you would need to work at height or with heavy fine dust and no proper extraction.
If the renovation was in a rental, or you are a landlord preparing the property to let, the same list helps with the next inspection. See our end of tenancy checklist for what agents and tenants look at. If you are preparing to sell, our pre-sale cleaning guide covers presentation.
Our perspective
We see the same pattern after almost every renovation: the home looks finished, but a film of fine dust sits in places nobody thought to check. It is on top of door frames, inside cupboard runners, in window tracks and across the tops of kitchen units.
That is why we treat an after builders clean as its own job, not a longer version of a regular clean. It needs the right method, damp wiping and proper vacuuming rather than dry sweeping, plus a top-to-bottom order so nothing is cleaned twice.
It also needs a second look. Our vetted, insured professionals bring supplies, including eco-friendly products, and our re-clean guarantee means that if something was missed, we come back to put it right. You see the price before you book, with no hidden fees, and you can book evenings and weekends, which suits homeowners who need the house ready the day after the builders leave.
Use the checklist in this article yourself if you enjoy the work. If you would rather spend your first week in the finished space instead of wiping it down, that is exactly what we are here for.

FAQ
What is classed as a builder's clean?
A builder's clean is the basic tidy a contractor leaves: debris removed, protective coverings taken up and surfaces roughly wiped and swept. It does not normally remove fine dust from inside cupboards, tracks and fittings. Agree in writing what your contractor will leave, so you know what remains for you.
What do I need for post-construction cleaning?
You need an M- or H-class vacuum or a suitable extraction unit, lots of microfibre cloths, buckets, a plastic scraper, gloves, eye protection and a dust mask. Add products suited to your surfaces, bags for waste and a stepladder. Avoid dry brushes and compressed air.
Should I clean before or after snagging?
Do a rough clean first so you can see defects clearly, then snag, then do a final clean once all repairs are finished. Fixing snags creates fresh dust, so cleaning only once at the start usually means doing it again.
How soon after the builders leave should I clean?
As soon as all the work and snagging repairs are complete, so dust does not get trodden into floors and soft furnishings. A short touch-up a few days later catches dust that settles afterwards.
Can I use a normal household vacuum?
For light dust, a vacuum with a good filter is fine, but for fine construction dust HSE advises an M- or H-class unit. Damp-wipe surfaces first so dust is not thrown back into the air.
