After Builders Cleaning Cost in Berkshire (2026 Guide)

After builders cleaning is the hardest cleaning job to price from a table, which is why most cost guides quietly give you a domestic cleaning tariff with a bigger number on it. The work is not a bigger version of a house clean. It is the removal of fine mineral dust from every surface in a building, repeatedly, until it stops reappearing — and that is why it is quoted in stages after somebody has actually looked at the site.

Why the price is not a property-size tariff

An end of tenancy clean can be priced by bedroom count because the property is finished, empty and in known condition. A post-construction property is none of those things. Two identical three-bedroom houses can be a day apart in labour depending on whether the trades dust-sheeted and vacuumed as they went or swept everything into a corner, whether floors were protected, whether there is paint and adhesive on glass and tiles, and whether the building is watertight and clear of tools.

So the honest structure is a fixed price agreed after a site assessment, with the scope and the number of visits stated. Anyone quoting a firm figure over the phone for a property they have not seen is either padding heavily to cover the risk or intending to have a conversation about extras later.

What the published UK figures actually say

There are two usable reference points and it is worth understanding what each one covers.

The gap between those two is the thing to pay attention to. At £32.50 an hour, the top of MyBuilder's £450 range buys roughly 14 cleaner-hours. A renovated four-bedroom house that needs a rough clean, a full detail clean and a settle-back visit will use considerably more than that. The national ranges describe a single-stage clean on a small, tidy job; they are not wrong, they are just answering a smaller question than most renovations ask.

How the stages work, and why there are usually two visits

We quote after builders cleaning in stages rather than as one number, because that is how the work actually happens:

1. Rough clean — bulk debris, offcuts, packaging, protective sheeting and the heavy surface dust. Typically half a day. On a large project this happens while the last trades are still finishing.
2. Detail clean — the real job. Every surface, top down: ceilings and coving, light fittings, extract vents, window frames and reveals, glass inside and out where reachable, tracks and hinges, radiators and behind them, skirting, sockets and switches, doors and their tops, inside every cupboard and drawer, sanitaryware, tiling and grout, floors last. From around six hours for a small flat to two or more days for a large house.
3. Settle-back visit — fine construction dust keeps dropping out of the air for days after the work stops. A property signed off as spotless on Tuesday will have a visible film on Friday. The second visit is what makes the handover hold.

That third stage is the single most common reason a cheap builders clean turns into a complaint. If a quote does not mention it, ask what happens when the dust comes back — and get the answer before you book, not after.

Why the dust is the whole job

Construction dust is not house dust with brick in it. HSE's description of the material is worth reading before deciding a domestic vacuum and a duster will cover it. Silica "is a natural substance found in varying amounts in most rocks, sand and clay" and is a major constituent of "bricks, tiles, concrete and mortar"; dust is generated "during many common construction tasks" including "cutting, drilling, grinding and polishing"; and the fraction that matters, respirable crystalline silica, is "too fine to see with normal lighting" (HSE). HSE describes silica as "the biggest risk to construction workers after asbestos".

Two honest qualifications, because this is a point cleaning companies routinely overstate. HSE's guidance is about protecting the people cutting and grinding the material, who are exposed heavily and repeatedly — not about a homeowner walking into a finished extension. And a builders clean is not a health intervention. What the HSE material does explain is the physical problem: the particles that matter are invisible, they are everywhere rather than in the obvious places, and they stay airborne long enough to resettle.

Which is why method decides the result far more than hours do:

• No dry sweeping and no dry dusting. Both put the finest dust straight back into the air, where it lands again behind you. This is the single biggest difference between a builders clean and an enthusiastic tidy-up.
• Filtered vacuum extraction rather than a domestic cylinder vacuum, which passes fine dust through and blows it out of the exhaust.
• Top down, and more than once. Ceilings, coving, light fittings and the tops of doors before anything at floor level, then the whole sequence again after everything has settled.
• Damp methods and correct dwell time on residues — plaster splashes, adhesive, silicone smears, paint speckle and cement film all need softening rather than scraping, or you take the finish off with them.
• Everything opened. Inside cupboards, drawers, appliance housings, window tracks, socket faces and extract vents. Dust does not respect closed doors during construction and it does not leave when the trades do.

What changes the price

• How the site was left. A project where trades cleared and vacuumed daily can be half the labour of one where everything was swept into the hallway.
• Whether the building is finished. Cleaning around outstanding snagging means doing parts of it twice, and it should be priced that way or scheduled later.
• Glass. Paint speckle, adhesive residue and plaster film on windows and shower screens is slow, careful work — often the largest single line after floors.
• Floor type. New timber, stone, resin and large-format tile each need a different approach and some need sealing considerations respected; grout haze is its own job.
• Carpets and soft flooring, which are almost always a separate line — see our carpet cleaning cost guide for per-room pricing.
• Access and logistics. Parking, lifts, stair carries, restricted hours and shared entrances all add time on flats and commercial units.
• Waste. Cleaning contractors are not licensed waste carriers, so builders' waste, offcuts and packaging normally leave with the contractor, not with us.

What an after builders clean will not do

The list that prevents disappointment, and one item on it is a safety boundary rather than a preference.

• Asbestos. HSE states that asbestos "can be present today in any building built or refurbished before the year 2000", and that "when materials that contain asbestos are disturbed or damaged, fibres are released into the air" (HSE). We are cleaners, not a licensed asbestos contractor. If work in a pre-2000 property has disturbed material that has not been surveyed, that is a survey-and-removal job and cleaning must wait for it.
• Snagging. Chipped paint, poor caulking, misaligned doors, grout gaps and damaged finishes are the contractor's to put right. Cleaning reveals them; it does not fix them.
• Damaged surfaces. Scratched glass, etched stone, paint on carpet that has cured, and adhesive that has bonded to a finish may not come off without taking the finish with it. We will tell you before trying rather than after.
• Waste removal. Builders' rubble, packaging and offcuts are registered waste-carrier work.
• Making an unfinished building habitable. If the trades are not done, the clean is not the last job — it is a job that will need doing again.

Getting a quote you can actually compare

1. Ask for a fixed price after a site visit, not an hourly rate with an open end.
2. Ask how many visits are included and whether the settle-back visit is one of them.
3. Ask what is excluded — glass, carpets, external windows, waste, high-level access.
4. Ask whether the property will be empty of tools and trades on the day, and hold your contractor to it. A clean done around three trades is a clean done twice.
5. Compare quotes on stages and scope, not on the headline figure. Two numbers that look £200 apart usually differ by an entire visit.

After builders cleaning across Berkshire & Surrey

We price after builders cleaning as a fixed job after a site assessment, based on size, condition and the number of stages the project genuinely needs — with the settle-back visit built into the quote rather than added to the invoice. Plant-based products and reusable colour-coded microfibre are standard, which matters more than usual on a handover where somebody is about to move in.

The same team handles new-build handovers, extensions, loft and kitchen refits and phased commercial fit-outs. If the property is a rental going straight back on the market, an end of tenancy clean is a different specification and priced differently — and if the work was a refresh rather than a build, a deep clean is usually the right job; our deep clean cost guide has those numbers.
