When to Book the Post-Construction Clean
Dry, Then Damp
Dust Off Before Wet Wiping
A builders clean is the heavy clean carried out once building or refurbishment work has finished and the trades have left, before a property is inspected, handed over or occupied. Our specialist team takes off the fine plaster, cement and sanding dust that settles on every surface, loose debris, paint splashes, labels, protective film and light adhesive residue. It cleans new fixtures, kitchens, bathrooms, glass and floors, working from high level down with the floors last. It is not a repair, a rubble clearance or a decorating job, and it is not the finishing polish: that is a sparkle clean, which follows it. A deep clean is a different job again, resetting a building that has been in use. The areas are agreed in a written quote, each is checked against it, and before-and-after photos show the result.
Dust Off Before Wet Wiping
Holds Fine Dust in the Vacuum
Fine dust is the main problem after building work, and an ordinary vacuum can lift it straight back into the air. HEPA-filtered vacuums hold it instead. The team takes dust off dry first, then wipes surfaces damp, working from high to low. Equipment and products are included on every contract.
Four Things We Set Out on Every Job
The contractor's last day and the client's first sit close together, and the clean has to fit between them. These are the four things that stay the same on every post-construction job.
The people who attend are directly employed and trained for the work. New finishes mark easily, so the person cleaning a worktop, a glazed door or a floor needs to know which product and method suit each one.
We operate with full insurance cover and recognised industry accreditations, delivering deep cleaning services in line with professional and safety standards.
A walk-through against the written scope comes before sign-off. Anything missed is noted and put right, and before-and-after photos are taken for your records.
Handover dates move on building projects. We work evenings and weekends where the programme needs it, and plan the visit back from the date the contractor hands the space over.
Cleaning and facilities management for London businesses since 2001. Give us the address and the date the contractor finishes, and we will arrange a survey and send a written quote.




The survey or photos show how much dust, debris and residue the works left, which floors and finishes are in the property, and how many areas there are. That sets the price and the time on site in the written quote. The four steps below are the same on every job.
If your property requires additional cleaning beyond this service, our specialist teams provide a range of professional solutions.
What contractors, developers and property managers ask before booking the clean after building work.
A builders clean is the heavy clean after construction or refurbishment work has finished, carried out before a property is inspected, handed over or occupied. Our specialist team takes off the fine plaster, cement and sanding dust left on every surface, plus loose debris, paint splashes, labels, protective film and light adhesive residue, and cleans the new fixtures, glass and floors. It does not include repairs or rubble clearance, and the finishing polish is a separate sparkle clean. Each area included is named in the quote before the visit.
Yes. Our specialist team cleans after building work in offices, shops and commercial fit-outs, and in homes that have been renovated, extended or converted into flats. Both start with dust and finish with floors, but the scope differs. A commercial floor may bring glazed partitions, many fittings and wide areas of flooring, while a home brings a new kitchen, bathrooms and several rooms of skirting. The survey, or photos sent in, settle which, and the quote lists each area.
A builders clean covers every surface within reach once the trades have gone: ledges, sills, shelves, door frames, skirting boards, worktops, fittings, glass and floors. Dust high above floor level, such as ceiling voids and the tops of services, needs access equipment and is listed in the quote if wanted. Surfaces inside built-in units and behind fixed appliances are left unless the quote names them. Dust is taken off dry with HEPA-filtered vacuums, then surfaces are wiped damp, so the dust is lifted off and not smeared across the finish.

Once the last trade has finished and the contractor has taken away tools, materials and rubble, and before snagging, handover or the first occupants. A clean carried out earlier gets covered again whenever electricians, joiners or decorators still have work to do. The usual order is the contractor's clear-out, then the builders clean, then a sparkle clean just before handover if a polished finish is wanted. Send the handover date with the enquiry and the visit is worked out backwards from it.
Yes. Handover dates are set by the programme, so we plan the visit back from the date the contractor hands the space over. Send the address, the rooms involved and the date the trades will be out. We can work evenings and weekends where the programme needs it. No date is confirmed until the site or photos have been seen, because the amount of dust and the number of areas decide the time on site. If the date moves, tell us early and we will look at the options.

Yes. Equipment, products and uniforms are included in the price of every contract, never billed as extras. On a post-construction job that means HEPA-filtered vacuums to hold fine dust, dust removal equipment for ledges and edges, cleaning products chosen for each finish, and hand tools for lifting labels, film and light residue. We ask for access to the building and, usually, a working tap and socket, which a part-finished site does not always have. Mention it when asking for the quote if neither is connected yet.
Most of it, but no clean can promise every grain. Building work produces fine dust that hangs in the air and settles again over the following days, so a visit done while other trades are still working, or just after a big dusty job, may need a second pass. A sparkle clean before handover deals with what has settled since. The quote says what each visit covers, and the sign-off walk-through checks every area against it, so the result is judged against an agreed list.

Yes. It is a regular step between practical completion and handover on commercial and residential projects, booked by the main contractor, the developer or the fit-out team, and by property managers after landlord works. The programme can carry it because the quote fixes the list of areas and the date of the visit beforehand. Our team checks each area against that list before sign-off, and the before-and-after photos can go into the handover file. One quote can cover a whole building, floor by floor.
Yes. It is the main cleaning step before handover: every room is cleared of dust, debris and residue, new fixtures, glass and floors are cleaned, and the work is checked against the written scope. If the client wants a polished presentation finish for inspection or the first occupants, a sparkle clean can follow. Repairs, snagging items, decorating touch-ups and rubble removal stay with the contractor, and the quote shows exactly which areas and tasks are included.
