Builders Clean in London

After building or refurbishment work, fine dust, loose debris, paint splashes and fitting residue are left on every surface. Our specialist team clears them from offices, shops and homes across London, so the property can be inspected, handed over and occupied.

A written quote lists the areas and the work before the visit, timed to the date the contractor hands the space over.

Tell Us the Building

Tell us the address, the areas to be cleaned, what the works involved and the date the contractor hands the space over.

We Survey and Quote

Where the job needs it we survey first, then send a written quote with the agreed scope.

Post-Build Clean on Site

Our specialist team arrives with its own equipment and works through the agreed areas, taking dust off dry from high level down, wiping surfaces and finishing with the floors.

Completion & Sign-Off

Each area is walked against the agreed scope before sign-off, and before-and-after photos record the result.

Builders Clean After Construction or Refurbishment

What the Clean Takes Off After the Works

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.

Fine Dust Removal

Plaster, cement and sanding dust taken off ledges, sills, shelves, door frames, tops of fittings and the corners of rooms, using HEPA-filtered vacuums first and a damp wipe after.

Surfaces and Fixtures

Newly fitted worktops, units, handles, switches, sockets and light fittings wiped clean of dust, fingermarks and fitting marks, with the cleaning product chosen for each surface.

Internal Glass and Frames

Internal glass, glazed doors and frames within safe reach cleaned of dust, smears, paint splashes and sealant marks. Full internal glazing is covered by internal window cleaning, and all outside glass by external window cleaning.

Floor Cleaning and Loose Debris

Floors vacuumed and cleaned last, once the dust from above has come down, with loose debris bagged and put out for collection. Methods are agreed by floor type. Set-in damage needs hard floor cleaning or carpet cleaning.

Skirting, Edges and Detail

Skirting boards, architraves, window reveals, door frames and corners cleaned by hand, where a vacuum alone leaves a line of dust along the edge.

Kitchens and Bathrooms

New units, worktops, sinks, taps, toilets, basins, shower screens and tiles cleaned of dust, grout haze, silicone smears and fitting marks. Commercial catering kitchens have their own kitchen deep clean.

Adhesive and Residue Removal

Stickers, labels, protective film, masking tape and light adhesive residue lifted off glass, frames, appliances and fittings. Heavy paint, sealant or adhesive that has set hard is looked at on the survey, as removing it can mark the surface.

Final Walk-Through

A last walk-through of every room against the agreed scope, with anything missed put right and the after photos taken. If a polished presentation finish is wanted just before handover, a sparkle clean follows.

When to Book the Post-Construction Clean


  • When the last trade has left and the works are signed off as complete.
  • Before handover to a client, tenant or owner, so the space is not passed over dusty.
  • Before the first staff, tenants or residents move in.
  • After fixtures and fittings are in, because fitting leaves labels, film and marks.
  • Ahead of a snagging walk-round, so finishes are judged and not the dust on them.
  • After a home or office renovation, once the builders have gone.

Equipment and Method for Fine Dust


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.

  • HEPA-filtered vacuum systems for fine dust
  • Dust removal equipment for ledges and edges
  • Surface cleaning products chosen for each finish
  • Hand tools for lifting labels, film and light residue

The Bayleaf Standard

Handed Back Clean

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.

Our Own Post-Build Team

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.

Fully Insured & Accredited

We operate with full insurance cover and recognised industry accreditations, delivering deep cleaning services in line with professional and safety standards.

Quality Checked Before Completion

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.

Flexible, Reliable Scheduling

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.

Our standards, your success.

Methodology

How a Post-Construction Clean Works

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.

Post-Construction Clean Questions

What Contractors and Property Managers Ask

What contractors, developers and property managers ask before booking the clean after building work.

What is a builders clean?

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.

Is a builders clean suitable for homes and commercial projects?

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.

Does a builders clean include dust removal from all surfaces?

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.
