Finishing a renovation should feel exciting. Instead, many London homeowners find their new kitchen, extension or loft conversion covered in a fine grey film of plaster dust, with paint specks on the glass, adhesive on the tiles and sticker residue on every new fitting. Builders usually remove rubble, but they rarely leave a property truly clean. That is where professional after builders cleaning London services come in. The right team removes the dust properly, protects your new finishes and gets the property ready to live in, let or hand over.
This guide compares six options for post-construction cleaning in London. We ranked them on cleaning quality, safety training, insurance, pricing transparency and flexibility around building schedules.
Why After Builders Cleaning Is Different From a Normal Clean
- Fine dust gets everywhere. Plaster and sanding dust settles on high ledges, inside cupboards, in light fittings and on every horizontal surface. It reappears for days if it is not removed correctly.
- New finishes are easy to damage. Scrubbing paint off glass, stone or high-gloss units with the wrong tool can leave scratches that cannot be fixed.
- Residue needs the right products. Paint, plaster, grout haze, adhesive and protective film each need a different approach.
- Standard vacuums struggle. Fine construction dust can clog or damage domestic vacuum cleaners and blow back into the air.
- Safety matters. Building sites can still carry hazards, so cleaners need proper health and safety training.
Typical After Builders Cleaning Prices in London
UK price guides published in 2026 show these typical ranges for London, though every job is priced on its own condition:
| Property size | Typical London range |
|---|---|
| Studio | £160 to £220 |
| 1 bed flat | £200 to £260 |
| 2 bed flat | £220 to £310 |
| 3 bed house | £270 to £390 |
| 4 bed house | £300 to £450 |
| 5+ bed house | £350 to £650 |
The biggest cost drivers are the amount of dust and residue, the size of the property, access and parking, delicate surfaces such as natural stone, and any leftover building waste.
1. Techno Clean: Best After Builders Cleaning Service in London
Techno Clean earns the top spot because it treats after builders cleaning as a specialist service rather than a bigger version of a domestic clean. Based in Borehamwood and serving London and Hertfordshire, the company holds a 4.9 average rating from more than 180 reviews and has completed over 500 jobs across London. After builders cleaning is one of its most-booked services.
What Techno Clean’s after builders clean includes:
- Fine dust removed from every surface, working from high level downwards so dust is not spread back onto cleaned areas.
- Paint, plaster and adhesive spots lifted where safe, using the right equipment and products for each surface.
- Internal glass, frames and sills cleaned, including stubborn construction marks.
- Sticker and protective-film residue removed from new fittings, windows and appliances.
- Kitchens and bathrooms de-dusted and sanitised, ready for use.
- Floors industrially vacuumed and mopped, using equipment designed for construction dust.
Flexible for builders and homeowners: Techno Clean can stage its work around a contractor’s programme, from a rough clean mid-project to a final clean before handover. That makes it a good partner for refurbishment companies as well as homeowners and landlords. Rubble and builders’ waste stay with the builder, which keeps the scope clear.
Why it ranks #1: the team is IOSH health and safety trained, BWCA approved and trained, Solution World of Clean trained and Prochem trained. Cleaners are uniformed, vetted and checked before they start, and the company carries £5 million public liability insurance. Every job gets a fixed quote based on size, condition and access, usually within one working day, so there are no surprise charges on the day.
Verdict: for London homeowners, landlords and builders who want trained, insured specialists and a fixed price, Techno Clean is the best after builders cleaning service in London.
2. Fantastic Services
Fantastic Services is a large national home services company that offers after builders cleaning inside the M25. It charges by the hour, with detergents and equipment included, and members of its paid subscription club receive lower rates. It suits customers who want online booking with a large brand. Hourly pricing can make the final cost harder to predict on heavily soiled jobs.
3. Housekeep
Housekeep is an online cleaning platform that offers after builders cleaning across the UK, including London. Its standard clean covers surfaces, cupboard exteriors, skirting boards, appliance exteriors, internal windows, vacuuming and mopping, with optional extras such as inside the fridge, carpets and upholstery. It is convenient for straightforward jobs, though heavy construction dust may need a more specialist team.
4. Commercial Contract Cleaners
Larger commercial cleaning companies handle builders’ cleans on big developments and commercial fit-outs. They can bring large teams for multi-unit sites. For a single home, an extension or a flat refurbishment, they are often more expensive and less flexible than a specialist local company.
5. Your Builder’s Cleaning Arrangement
Some builders include a basic “sparkle clean” or arrange a cleaner at the end of a project. Check exactly what is included. Often it is a light clean to remove obvious mess, not a full detail clean of dust, residue and glass.
6. Regular Domestic Cleaners
Your usual cleaner may offer to help after building work. They know your home, but most do not have the equipment, products or training for construction dust and paint residue. Using household vacuums on fine plaster dust can also damage the machine.
How to Prepare for an After Builders Clean
- Wait until trades have finished. Booking before the last painter or electrician leaves often means paying for a second clean.
- Let the dust settle. Cleaning a day or two after work stops gives airborne dust time to land, which produces a better result.
- Ask the builder to remove waste. Rubble, offcuts and packaging should be cleared before the cleaners arrive.
- Flag delicate surfaces. Tell the cleaning team about natural stone, hardwood, high-gloss units and any special finishes.
- Check access and parking. London parking restrictions can affect arrival times and costs.
- Agree the scope in writing. Make sure the quote lists what is included.
What to Look For When Hiring
- Health and safety training, such as IOSH, for working around building sites.
- Public liability insurance to protect your property and new finishes.
- Fixed pricing rather than open-ended hourly charges.
- Proper equipment, including industrial vacuums suited to fine dust.
- Real reviews and before-and-after photos of genuine jobs.
- Flexibility to fit around your builder’s programme.
