Coleman Street
A full floor of over 1,800 m², four operatives, two days.
What we did, and what it changed.
The job
A global technology company's new City floor, handed back after fit-out in October 2025. A full floor of over 1,800 m². Four operatives, two days, 07:00 to 17:00 — roughly eighty operative-hours.
Post-construction is a different job from cleaning. Fit-out dust is abrasive, it is everywhere, and it keeps arriving from the ceiling void for days after the trades leave.
The carpet decision
We extracted the carpets rather than shampooing them. Construction soil sits down in the pile; surface cleaning lifts the top of it and leaves the rest to wick back up as it dries.
The recovered water in the gallery below is what came out. It is the least attractive photograph on this website and the most useful one — a client never sees this stage, and it is the only real evidence of the difference between the two methods.
The building was handed over on the date it was supposed to be handed over.
Filmed on the day. The water in the second clip came out of the carpet in the first one — construction soil that a surface shampoo would have left in the pile to wick back up as it dried.
We do not publish a client’s building without their agreement. This one asked to stay unnamed, so it is.

Other projects
Fit-out dust does not settle once.
It keeps arriving from the ceiling void for days after the trades leave, and it is abrasive. That is why a post-construction clean is a different job from a deep clean, priced and sequenced differently.
It comes back after you have cleaned
Dust sits in service voids, ceiling grids and cable trays and drops for days. A single clean too early looks finished on the day and wrong by the handover. The sequence matters more than the hours.
It is abrasive on brand-new surfaces
Construction dust carries plaster, silica and metal filings. Wiped dry across new glass, new worktops or a new floor it scratches them. The finishes you have just paid for are at their most vulnerable in this fortnight.
Carpet is the thing you pay for twice
Construction soil sits down in the pile. Surface shampoo lifts the top and leaves the rest to wick back up as it dries, so it looks clean, then does not. Extraction takes it out. The photograph of the recovered water on this page is the only honest evidence of that difference.
The handover date is usually contractual
Someone has committed to it — to a landlord, a board, or a workforce with a start date. We treat that as the fixed point and build the plan around it rather than quoting hours and hoping.
