What Is a Post-Builders Clean and What Does It Cover?
Understand what a post-builders clean involves, what cleaners can and cannot remove, and how to plan it after a renovation, extension or new build.
Once the tradespeople finish, you are left with a house that looks nearly done but feels unusable. Dust coats every surface, windows are splattered with paint, and floors are scuffed with plaster. A post-builders clean, sometimes called a post-construction or after-builders clean, is the final stage that makes a project feel complete.
What it is
A post-builders clean is a thorough, multi-stage clean carried out after building, plastering, decorating or refurbishment work. It goes well beyond ordinary cleaning because construction dust is fine and sticks to everything. Cleaners work from top to bottom, using damp wiping, vacuuming with fine-dust filters where available, and appropriate products for different materials.
For typical prices, see post-builders cleaning costs.
What it usually covers
- Dust removal from every surface, including shelves, skirting, door frames, light fittings, radiators and the tops of cupboards.
- Windows and frames, including cleaning glass and removing light paint splashes where safe.
- Floors, vacuumed and mopped, with care for new surfaces.
- Kitchens and bathrooms, including inside new cabinets, appliances and fittings, and removal of protective films and stickers.
- Walls and woodwork, wiped where finishes allow.
- Sockets and switches, wiped carefully.
- Light cleaning of radiators and vents.
What it usually does not cover
- Removing rubble, plasterboard or building waste, normally the contractor's responsibility.
- Repairing damage, such as scratched floors or splashed paint on carpets.
- Removing hazardous materials, such as suspected asbestos, which needs qualified specialists.
- Heavy cement or adhesive residue that cannot be removed without risk to the surface.
- Gardens and external landscaping.
Always ask a cleaner to confirm what is included.
Why dust is so persistent
Plaster and cement dust is alkaline and extremely fine. It can settle inside cupboards, vents and electronics. It also returns after the first clean, as air movement lifts settled particles. This is why a second light clean a few days later is common.
When to book
- After all trades have finished. That includes decorators, tilers and electricians.
- After snagging. Fix issues first so you do not have to clean twice.
- Before moving furniture in. Empty rooms are quicker and cheaper to clean.
- A few days before you move in, to allow for a follow-up clean.
How to prepare
- Agree a date with builders, so they leave the site clear of waste and tools.
- Remove or cover items you do not want dust on.
- Provide water, power and access.
- Take photos of surfaces beforehand, as a record.
- Tell the cleaner about delicate finishes, such as natural stone, unsealed wood or newly painted walls.
Questions to ask a cleaner
- Do you have experience with after-builders cleans?
- What equipment do you use for fine dust?
- How many people and how many hours will it take?
- Do you offer a follow-up visit?
- How do you handle paint or cement splashes?
Working with the builder
Some builders include a basic tidy, but not a detailed clean. Check your contract. If you pay a professional cleaner, say so in advance, so the site is handed over properly.
Booking help
On Compito, you can search by postcode, compare ID-verified local providers and message them with photos and the scope before you accept an offer and pay online. For a wider reset, you may also want a deep clean after the dust settles.
A staged approach
Professionals tend to work in a repeatable order, which is worth understanding so you can judge whether a cleaner has a sensible method.
- Remove loose debris and large dust by hand or with a brush, without sweeping vigorously.
- Vacuum high surfaces first, including ceilings, tops of cupboards and window frames.
- Damp wipe walls, woodwork, doors and fittings, rinsing cloths often.
- Clean windows and glass, carefully lifting paint with the right tool.
- Clean kitchens and bathrooms, removing films and stickers.
- Vacuum and mop floors last, often twice.
- Final walkthrough with you or the site manager.
Worked example
A bathroom renovation has finished: new tiles, a shower enclosure and fresh paint. Dust has spread to the landing and bedroom. A cleaner might spend about three hours on the bathroom itself, wiping every tile, fitting and the inside of cabinets, then an hour on the adjoining hallway and bedroom. Because grout haze can appear as tiles dry, they may advise a second look a few days later.
Common mistakes
- Using a standard household vacuum, which can blow fine dust back into the air.
- Wiping dry surfaces with a dry cloth and scratching them.
- Cleaning before surfaces have fully cured.
- Using strong acids on new tiles or natural stone without advice.
- Forgetting the insides of cupboards, vents and window tracks.
Health and safety
Fine dust can irritate airways, so ventilate, wear a mask for DIY and keep children, pets and vulnerable people away until the main work is done. If the property is older and you suspect asbestos or lead paint in materials that were disturbed, stop and seek specialist advice before cleaning. Do not use your household vacuum on suspected hazardous dust.
Frequently asked questions
How long does it take?
A small room or flat may take a few hours with two cleaners. A whole-house renovation can take one to three days.
Can I do it myself?
Yes, for small jobs, but it is time-consuming and dust can irritate the airways. Wear a mask and ventilate.
Is dust harmful?
Fine construction dust can irritate eyes and lungs, particularly for those with respiratory conditions. Ventilate well and keep vulnerable people away until it is cleaned.
Should I clean before or after painting?
After. Dust settles on wet paint and cleaning disturbs it, so wait until painting and snagging are finished before the main clean.
