Building work and renovation leave a specific kind of mess. Not just visible mess — the obvious rubble, dust sheets, and tool marks that you expect — but fine construction dust that has settled into every corner, crevice, and sealed space in the affected areas and beyond. This dust is finer than household dust, behaves differently, and requires different equipment to remove properly.
If you attempt to clean a post-renovation space with standard domestic cleaning tools, you will move the dust rather than remove it. Standard vacuums recirculate fine construction particles rather than capturing them. Standard mops spread dust through water rather than lifting it. The result is a property that looks cleaned but retains a layer of fine dust on every surface that becomes visible again within days.
This guide covers what after builders cleaning actually involves, what it costs in London, and how to choose a company equipped to do the job properly.
What Is After Builders Cleaning?
After builders cleaning — also called a builders clean, post-construction cleaning, or post-renovation cleaning — is the specialist clean carried out after building, renovation, or refurbishment work is complete. It applies to a range of situations:
- A single room refurbishment — a new kitchen or bathroom installation
- A whole-property renovation or extension
- New build properties before first occupancy
- Commercial refits and office renovations
- Properties after emergency repair work such as flood or fire remediation
In every case, the defining characteristic is the presence of construction residue — fine dust, plaster spots, paint splashes, adhesive, silicone, and grout residue — that requires targeted specialist treatment rather than a thorough domestic clean.
Why Standard Cleaning Does Not Work After Building Work
There are two core reasons why a domestic deep clean is not suitable after construction work.
First, the dust. Construction dust — from sanding plaster, cutting tiles, mixing concrete, and drilling — is far finer than household dust. It permeates fabrics, settles inside sealed drawers and cupboards, and coats surfaces that appear clean from a standing position. A standard vacuum cleaner picks up larger particles but exhausts fine dust back into the air. A HEPA-filter vacuum captures particles at the particle size construction dust actually is. Without HEPA equipment, vacuuming a post-construction space just redistributes the fine dust.
Second, the residue. Paint splashes on window glass, silicone marks on tiles or bath surfaces, tile grout on floor tiles, adhesive on new flooring, and plaster spots on skirting boards all require specific chemical and mechanical treatment to remove without damaging the surfaces underneath. This requires knowledge of what product is safe on what surface, and what technique avoids scratching or staining new finishes.
After Builders Cleaning Prices in London (2026)
Post-construction cleaning is priced by scope and condition. Condition matters particularly here because the amount of construction residue varies substantially between a light refurbishment and a full gut-and-rebuild.
| Scope | Approximate Price Range |
|---|---|
| Single room renovation — kitchen or bathroom | £150 – £300 |
| 1-bedroom flat — full renovation | £300 – £450 |
| 2-bedroom flat — full renovation | £400 – £600 |
| 3-bedroom house — full renovation | £550 – £850 |
| 4-bedroom house — full renovation | £700 – £1,100 |
| Commercial fit-out (small) | £400 – £900+ |
These prices assume the construction team has completed a rough clean — removing rubble, doing a rough sweep — before handover. If the space is left with materials, rubble, and unswept floors, the cleaning time increases significantly.
What After Builders Cleaning Covers
Dust Removal
Systematic removal of construction dust from every surface in the affected areas and any adjoining areas. This is done with HEPA vacuum equipment first — before any wet cleaning — to capture rather than redistribute the fine particles. Surfaces include: all horizontal ledges and shelves, skirting boards, door frames, window sills, banisters, light fittings, and tops of walls near ceiling joins where fine dust settles.
Floors
HEPA vacuum of all floor surfaces before any wet cleaning. Removal of paint spots, tile grout residue, plaster marks, and adhesive from hard floors using appropriate products for the specific floor type. Mopping with a clean solution after all dry cleaning is complete. For carpets: thorough vacuum to remove embedded construction dust — this may require a professional-grade extraction vacuum rather than a standard domestic one.
Windows and Glass
Removal of paint spots, silicone splashes, sticker residue, and construction dust from all glass surfaces. Cleaning of window frames — inside and where accessible outside — to remove dust and any paint overspray.
New Installations — Kitchen and Bathroom
Wiping inside all new fitted units before use — kitchen and bathroom cabinets accumulate construction dust during installation. Removing installation residue and protective film from new appliances. Descaling and polishing new chrome fixtures. Cleaning new tiles and grout — including removing any grout haze from the tile faces.
Walls
Light dust removal from painted walls. Identifying and noting (but not necessarily treating) any paint marks or scuffs that may require attention from the construction team rather than the cleaning team.
What After Builders Cleaning Does Not Cover
- Removing rubble, building materials, or construction debris — this is the contractor’s responsibility before handover
- Cleaning areas still under active construction
- Repairing damage to surfaces caused during construction
- Skip hire or waste disposal
How Long Does a Post-Construction Clean Take?
Time depends heavily on the scope of work and condition of the site at handover:
| Scope | Approximate Time (2-person team) |
|---|---|
| Single room — new kitchen or bathroom | 4 to 6 hours |
| 1-bedroom flat — full renovation | 1 day |
| 2-bedroom flat — full renovation | 1 to 1.5 days |
| 3-bedroom house — full renovation | 1.5 to 2.5 days |
| 4-bedroom house — full renovation | 2 to 3.5 days |
Properties where the construction team has done a proper rough clean before handover — swept floors, removed rubble, cleared dust sheets — typically take 30 to 40 per cent less time than sites where no rough clean has been done.
When to Book
Book the after builders clean as soon as the construction team has completely vacated the property. Do not move any furniture, belongings, or personal items back into the space before the professional clean is complete. Fine construction dust settles repeatedly when a space is occupied — moving boxes and furniture around in a dusty space means those items accumulate dust that will need to be cleaned again.
Before the cleaning team arrives, confirm with your contractor: all materials and tools have been removed; the rough sweep has been done; power, water, and hot water are available; and any areas still to be completed are clearly identified so they can be cleaned around.
What to Look for in a Post-Construction Cleaning Company
HEPA vacuum equipment: Ask specifically whether the company uses HEPA-filter vacuums. If they use standard domestic or commercial vacuums, they are not equipped to properly remove fine construction dust.
Experience with construction residue: Paint removal, adhesive removal, and grout haze removal from tiles require specific products and techniques. Ask whether the company has experience with these specifically — general domestic cleaners often do not.
Floor protection: New flooring installed as part of a renovation is at risk during the cleaning process. Ask whether protective covering will be laid during cleaning.
Public liability insurance: More important in a post-construction environment than a standard domestic clean, given the higher value of new installations.
After the Clean: Starting a Regular Cleaning Arrangement
Once the post-construction clean is complete, the property is at a high standard. This is a good time to establish a regular cleaning arrangement before it deteriorates again. UrbanShine Cleaners provides weekly and fortnightly domestic cleaning across Central London, South London, and East London
After Builders Cleaning for Commercial Properties
Post-construction cleaning for commercial properties — offices, retail units, restaurants, gyms — follows the same principles as residential but at a larger scale and with different surface types. New commercial floor finishes, newly installed commercial kitchen equipment, freshly plastered partition walls, and exposed concrete finishes all require specific products and knowledge to clean without damage.
UrbanShine Cleaners provides after builders cleaning for commercial properties including offices, restaurants, and retail spaces across London. For commercial projects, a site visit before quoting is standard practice, as scope and condition vary significantly more than in residential settings.

How to Prepare for the After Builders Clean
A few practical steps make the clean more efficient and the result better:
- Confirm with your contractor that all building materials, tools, and waste have been removed from the site before the cleaning team arrives
- Ensure the rough sweep has been done by the construction team — large debris and dust should be cleared before the specialist clean begins
- Identify which new surfaces and finishes are fragile or require specific treatment — communicate this clearly at booking
- Arrange for utilities to be fully connected including hot water and electricity
- Clear access to all areas including any that may have been sealed off during construction
The Cost of Getting This Wrong
A post-construction clean done with the wrong equipment or without sufficient expertise can cause more damage than it addresses. Using a standard vacuum on fine construction dust spreads it through the air and allows it to resettle on new paintwork and new surfaces. Using the wrong cleaning product on a new stone floor, new wood flooring, or a newly installed shower tray can stain, etch, or otherwise damage a finish that cannot be cost-effectively repaired.
UrbanShine Cleaners teams that carry out post-construction cleans are briefed on the correct products for different surface types and the specific challenges of construction dust removal. This is not a job that benefits from the cheapest quote available.
Frequently Asked Questions: After Builders Cleaning in London
How soon after building work finishes can the clean be booked? As soon as the construction team has vacated and completed the rough clean. There is no benefit to waiting — fine construction dust settles and re-settles with any activity in the space, so the sooner the professional clean happens after the builders leave, the better.
Does after builders cleaning include cleaning external areas? External areas can be included as an additional scope item — for example, a newly paved patio with construction dust, or newly installed external windows. Confirm at booking and the quote will reflect the additional areas.
Will the cleaning team move the remaining construction materials? No. After builders cleaning addresses the clean-up after materials have been removed. If materials, tools, or waste are still present, these should be cleared by the contractor before the cleaning team arrives.
Do I need to provide water and power? Yes. Hot water and electricity are required for an effective post-construction clean. Confirm that both are connected and working before the team arrives.
