After Builders Cleaning London: Costs, Stages and What It Really Involves

After builders cleaning is the deep clean a property needs once the tools are down and the dust has finally settled. In London it usually runs somewhere between about £200 and £650 for a flat or small house, and more for a big renovation or a whole-house refurb. The job clears fine construction dust, plaster splashes and paint marks, then brings the place back to a liveable, handover-ready finish. If you have just finished a build, or you need a site signed off for the client, this is the clean that gets you there.

We do this work across North London and the Hertfordshire borders every week, so here is the honest version: what it involves, what it costs, and why a normal clean won't get you there.

What is after builders cleaning?

After builders cleaning, sometimes called post construction cleaning, is a specialist clean for a property that has just come out of building work. A renovation, an extension, a loft conversion, a new bathroom, a full refurb, a new-build handover. The work leaves behind a very particular mess. It's not everyday dirt. It's cement dust, plaster, silicone smears, paint flecks, adhesive, grout haze on new tiles, and protective film on windows and appliances.

Two very different people usually book it. Homeowners who have been living around a building site for weeks and want their home back. And builders, developers and refurbishment firms who need the property spotless before the client walks in. The clean is the same skill either way. The deadline and the standard are what change.

The three stages of a builders clean

A proper builders clean is not one pass with a hoover. On a bigger job it works in three stages, and knowing them helps you brief a cleaner and understand a quote.

Stage one, the builders clean. This is the rough first pass, often done as the trades wrap up. Offcuts, packaging, empty tubs, bags of rubble and general debris get hauled out. We sweep and vacuum so the space is safe to move around and the real cleaning can start. It's about clearing, not detail.

Stage two, the deep clean. This is the heavy lift, top to bottom. Every surface, wall, ceiling, frame and skirting gets the dust taken off. Paint specks and plaster get scraped and washed away. The new kitchen and bathroom get a full deep clean. Most of the hours on the job live here.

Stage three, the sparkle. The finishing pass, done just before handover or move-in. Glass polished, chrome and fittings buffed, floors finished, every ledge and corner checked. This is the detail a buyer or an inspector notices, so it comes last, once nothing else is going to re-settle. If you want to see how we run this end to end, our after builders cleaning specialists in London handle all three stages on a single visit for most homes.

What an after builders clean actually covers

The whole point is the fine detail a standard clean skips. On a typical job we work through:

• Fine construction dust, everywhere it hides. On top of door frames, behind radiators, in light sockets and switches, along skirting, on window ledges and inside cupboards.
• Plaster, paint and adhesive. Splashes on floors, glass and tiles, paint runs on frames, silicone and sealant smears, sticker and label residue on new windows and appliances.
• Grout and cement haze. The cloudy film new tiles carry after they're laid and grouted, buffed off so the surface actually looks new.
• Extractors, vents and ducts. Extractor fans, trickle vents, MVHR grilles and the tops of units where dust packs in and later blows back out.
• Full detail on new installations. Inside and outside kitchen units, appliances, the bathroom, taps and screens, then floors cleaned to suit the material, whether that's tile, engineered wood, vinyl or stone.

If the build has left carpets grey with dust, that's usually a separate task on top, and our professional London carpet cleaners can lift construction dust out of the pile rather than just skimming the surface. The same goes for a wider whole-home refresh once the dust is gone, which is where a one-off deep cleaning service picks up.

Why a normal clean doesn't cut it

Here's the part people underestimate. Fine construction dust behaves nothing like household dust. It's far finer, it clings, and a normal hoover without the right filter just fires it straight back into the air. You wipe a shelf, and an hour later everything is grey again. That's not a bad cleaner. It's the wrong kit for the job.

There's a health side too, and it matters. Cutting, drilling, grinding and sanding building materials creates respirable crystalline silica, a dust so fine you can't see it in normal light. The Health and Safety Executive is blunt about it: silica is the biggest risk to construction workers after asbestos, and long exposure is linked to silicosis, lung cancer and COPD. That dust settles all over a finished property. Clearing it properly, with HEPA-filtered vacuums and a wet-wipe method that traps rather than spreads it, is the difference between a home that's actually clean and one that just looks clean until you breathe.

How much does after builders cleaning cost in London?

Price depends on the job, but published UK cost guides give a useful picture of the London market. Most quote roughly £20 to £45 per hour per cleaner. By property, a studio or one-bed flat tends to land around £160 to £300, a two-bed nearer £220 to £450, and a three or four-bed house anywhere from £270 up to £900 once the build has been heavy. Big homes and full gut refurbs climb past £1,000, sometimes to £1,500 or more.

A few things move the number:

• How heavy the build was. A single painted room is a light clean. A structural refurb with new kitchen, bathroom and floors is a different scale of work.
• Size and access. Square metres, number of floors, stairs, and whether there's parking. London jobs run around 20% dearer than the rest of the UK, and prime central boroughs sit higher again than outer London.
• The finish you need. A basic clear-out costs less than a full sparkle to handover standard.
• Extras. Carpet or upholstery cleaning, internal windows, and waste removal are often priced on top, with carpets commonly adding £50 to £150.

Bigger commercial fit-outs and new-build sites are sometimes quoted by the day for a two or three-person team, or per square metre. We don't work off a fixed rate card, because two "three-bed" jobs are rarely the same. We give you a free, no-obligation quote based on the actual property, how heavy the build was and the access on the day. Prices also shift a little by area, and you can see across North London and Hertfordshire where we cover.

For builders and developers: handover-ready, on deadline

If you're a builder or developer, the clean isn't about a tidy home. It's about signing the job off. The property has to pass a client walk-through or a snagging inspection, and the clean is often the last thing standing between you and handover.

We work to that reality. Our teams are DBS-checked and the company carries £5 million public liability cover, so we're insured to be on site around your trades and your client's property. We can fit around snagging and a fixed handover date, cleaning stage by stage as areas are completed rather than holding everything to the end. Construction waste is handled properly too. Anyone who transports waste as part of their business must register as a waste carrier with the Environment Agency, so removal is done the right way, not fly-tipped. For developers turning over multiple units or a whole site, our cleaning for builders and refurbishment firms is built around handover deadlines. The volume of work we've done shows in the feedback, and we're rated 4.9 from 180+ reviews across 500+ completed jobs.

Frequently asked questions

How much does after builders cleaning cost in London?

London market guides put most flats and small houses in the region of £200 to £650, with larger homes and heavy refurbs running higher. The real figure depends on size, how much building work was done, access and the finish you need. We quote free, based on your actual property.

How long does an after builders clean take?

A one or two-bed flat is often a single day for a team. A larger house or a heavy refurb can take two days, especially if it runs across all three stages. We'll tell you the realistic time when we quote.

Is rubbish and debris disposal included?

Light debris and packaging left from the build can usually be cleared as part of the clean. Larger volumes of construction waste are removed and disposed of correctly, and we'll flag any extra cost for that upfront rather than surprise you with it.

Can I just do the after builders clean myself?

You can, but fine construction dust is stubborn and it comes back fast without HEPA filtration and the right method. Most people find they clean the same surfaces three times and still can't shift the grey film. For a handover or a sale, doing it yourself rarely pays off.

How soon after the work finishes can you clean?

As soon as the trades are done and the site is safe to work in. For builders, we can also clean in stages as sections are completed, so the final sparkle lands right before your handover date.
