If your builder has mentioned a sparkle clean, or you have spotted the term on a snagging list, you are probably wondering how it differs from a normal clean. In short, it is the last stage of construction cleaning, carried out once the trades have finished and the dust has settled. This guide explains what it covers, when it should happen and what to expect in a London home.
Most cleaning contractors split post-build cleaning into three stages, and the sparkle clean is the final one. The rough clean happens while work is still ongoing and deals with bulk debris, offcuts, packaging and the worst of the dust. The builders clean, sometimes called the first fix clean, follows once the main trades are out and covers surfaces, floors, windows and sanitaryware so the property is usable.
The sparkle clean comes after all of that, typically a few days to a week later, once the fine dust that always resettles has had time to drop. It is a slow, detailed clean intended to bring a property to handover or move-in standard. On a loft conversion or rear extension in a family home it is usually the point at which the rooms genuinely feel finished rather than just tidy.
The defining feature is attention to detail rather than speed. Cleaners work top to bottom in each room, so anything dislodged from high level is picked up on the way down. Expect the job to take roughly one to two hours per room for a good standard, which is why a three-bedroom refurbishment in Walthamstow or Ealing often takes a small team most of a day.
Plaster dust is the main enemy. It is fine enough to pass through most vacuum filters and settles in places a general cleaner would never look, such as the inside of extractor hoods, radiator fins and the tracks of sliding doors. A proper sparkle clean uses HEPA-filtered vacuums and microfibre cloths rather than dry dusting, which just moves the problem around.
Timing matters more than anything else. If a sparkle clean is done while a decorator is still touching up or a plumber is due back to fit a tap, it will need doing again. Ask your builder for a firm completion date and book the clean for a day or two after the last trade has left. If the property has been sealed up and heated, dust settles faster and one visit is usually enough.
On larger domestic jobs in London the sparkle clean is often written into the building contract and organised by the main contractor. On smaller projects, or where you have managed trades yourself, it usually falls to the homeowner. It is worth checking your quote, because a builder who says the job includes a clean may only mean a broom sweep and a skip, not a handover-standard finish.
Prices in London vary with the size of the property, the finish level and how much residue the trades have left behind. As a rough guide, a sparkle clean on a one-bedroom flat tends to fall somewhere in the £250 to £450 range, while a three or four-bedroom house after a full refurbishment can run from £500 to £1,000 or more. A single-room job such as a new kitchen is often quoted as a half-day rate.
The main drivers are the amount of plaster and sanding dust, the number and size of windows, whether protective film and tape need removing, and access. A period house with sash windows and ornate cornicing takes longer than a new-build flat with flush finishes. Parking and congestion charge zones also add to the cost of an inner-London visit, so it helps to mention these when you ask for a quote.
A reputable company will want to see photos or visit before pricing, and will tell you honestly if the property is not ready. Being asked to postpone is a good sign, not an inconvenience, because it means they intend to do the job once and do it properly.
No. An end of tenancy clean deals with everyday dirt and wear in a lived-in home, whereas a sparkle clean is designed to remove fine construction dust, paint spots, adhesive residue and protective film from a newly finished property.
Ideally two to seven days after the final trade has left, so any airborne dust has settled and no further work will disturb the finish. Cleaning too early is the most common reason a second visit is needed.
You can, but plaster dust clogs domestic vacuums quickly and tends to smear when wiped with a damp cloth. A professional clean uses HEPA filtration and the right products for glass, grout haze and silicone, and typically saves a homeowner several weekends of effort.
