The service, locally
After builders cleaning in Mayfair W1
W1's period stock rewards patience over pressure — plasterwork dry-brushed from a pole, joinery vacuumed out before it is wiped in this 88% flats neighbourhood, with Westminster parking rules in play — and 57% of W1 homes being privately rented, and newly oiled floors treated with exactly what the finisher specified and nothing else.
Refurbishment work in Mayfair is restoration as much as construction: original plaster, joinery, glass and floors that cannot be replaced if a product marks them on W1 jobs, with 57% of W1 homes being privately rented.
Typical works here: period whole-house refurbishments and conservation-area work. Access and parking: Extremely tight kerbside, mews arches under 2.1m and listed interiors needing floor and stair protection.

- Congestion Charge and ULEZ both apply at this address — both are already inside the band above.
- Westminster City Council permits and bay suspensions are arranged and paid for by us, not added to your invoice.
- Includes the 72-hour re-sparkle promise: if dust settles again before handover, tell us within 72 hours and we come back to it free.
How the project runs
A builders clean in Mayfair from programme to sign-off
- Tell us the works, not just the bedroomsA single kitchen refit, a rear extension, a loft, a whole-house refurb or a new-build handover are different jobs.
- Get a fixed price and a slot in your programmeThe estimate is fixed against the works, the dust level and any add-ons.
- Stage 1 while the last trades finish, if you need itContractors usually book a rough clean so the site stays workable: debris and sheeting out, floors HEPA-vacuumed, labels off, everything safe for second fix and snagging.
- Stage 2 — the full post-construction clean, top downOnce the site is clear, a DBS-checked team works ceiling to floor with HEPA extraction: high dusting, ledges, joinery, glass, sanitaryware, appliances, then floors last — twice over, because fine dust falls again.
