Detailed care for luxury finishes
Fully insured & vetted team
From post construction cleaning to post renovation deep cleans, our specialist builders clean service covers every stage of your project. Whether it's a new build handover or refurbishment completion, we deliver handover-ready results.
Dust extraction & debris removal
M-Class extractors fitted with H13 HEPA filters, worked from the ceiling down before anything gets wiped. Fine plaster and silica dust ends up in the machine, not back in the air or ground into new floors.
Deep clean of kitchens & bathrooms
Complete sanitisation and polish of all new fittings, appliances, tiles, and grouting. Removing protective films, adhesive residue, and builder's marks for a showroom finish.
Specialist surface care
Marble and limestone get pH-neutral products, never acid. Lacquered joinery gets microfibre and nothing abrasive. Lime plaster and unlacquered brass are cleaned dry, and anything unusual gets a test patch first.
Specialist window cleaning - internal & external
Removing construction residue, paint splatter, and cement from all glazing types. Crystal-clear results for skylights, bi-folds, and hard-to-reach windows.
Skirting boards, doors & all fittings
Detailed cleaning of all woodwork, door frames, handles, and fixtures. Removing dust, paint marks, and fingerprints for a pristine handover-ready finish.
Hard floor polishing & carpet cleaning
Professional treatment for all flooring types. From buffing hardwood and polishing tiles to deep cleaning carpets and removing construction stains.
Sparkle clean & staged construction cleaning
Second stage clean after the initial builders clean, once dust has resettled. Our staged construction cleaning includes multi-stage cleans for developer handovers, achieving a sparkle standard ready for occupation or photography.
Builders dust is far finer than household dust. Plaster, filler and cut concrete break down into particles small enough to pass straight through a domestic vacuum and out of the exhaust. That's why we never bring one to site.
Every builders clean starts with extraction, not wiping. We vacuum every surface from the ceiling down with M-Class machines, the minimum class HSE guidance points to for construction dust, including the respirable silica from cutting brick, tile and concrete.
Our extractors run H13 HEPA filters, graded under EN 1822. An H13 filter captures at least 99.95% of particles at the size filters find hardest to stop, roughly 0.1 to 0.3 microns.
A HEPA filter on its own doesn't make a vacuum fit for builders dust. The dust class tests the whole machine, seals and bag included, so fine dust can't leak around the filter. Plenty of household vacuums say HEPA on the box. That isn't the same as M-Class.
Vacuums and extractors are tested under BS EN 60335-2-69
| Class | Lets through | Made for |
|---|---|---|
| L | Under 1% | General low-hazard dust. Not suitable for plaster or silica. |
| M | Under 0.1% | Plaster, filler, wood, concrete and silica dust. The right class for a builders clean. What we use |
| H | Under 0.005% | High-hazard and carcinogenic dust, such as old lead paint and mould. |
An H13 filter catches at least 99.95%
Graded under EN 1822 at the particle size filters find hardest to catch. The class covers the machine; the H13 grade covers the filter inside it.

No. We bring everything, including M-Class dust extractors with H13 HEPA filters, pH-neutral products for stone, and the scrapers, cloths and ladders the job needs. All we need from you is access, running water and power.
Yes. Every builders clean uses M-Class dust extractors fitted with H13 HEPA filters. A domestic vacuum, even one sold as HEPA, isn't built for plaster and silica dust and tends to push the finest particles back into the room.
Both are tested under BS EN 60335-2-69. An M-Class machine lets less than 0.1% of dust back out and is the standard for plaster, wood, concrete and silica dust. H-Class lets less than 0.005% out and is meant for carcinogenic and high-hazard dust such as old lead paint and mould. For a normal builders clean, M-Class is the right tool.
H13 is a grade under EN 1822. The filter has to capture at least 99.95% of particles at the size it finds hardest to stop, roughly 0.1 to 0.3 microns. H14 goes further at 99.995%. The grade describes the filter. The dust class describes the whole machine.
