Closed cell spray foam removal in London is what we do every week across Greater London. If a surveyor has flagged your loft, a lender has stalled your mortgage, or you have inherited a roof full of hard foam, we take it out cleanly, dispose of it legally, and leave the timbers ready for inspection. We cover lofts, attics, roofs and cavity walls from Westminster to Croydon.
Closed cell spray foam removal in London means mechanically cutting, chiselling and vacuuming out cured polyurethane foam from roof rafters, loft decks and wall cavities. Closed cell foam sets hard, so it cannot be peeled off like open cell spray foam. We cut it back with reciprocating saws and oscillating multi-tools, then finish the timber with dry ice blasting or sand blasting media to clear the last of the adhesive residue. An industrial vacuum and air scrubber run the whole time to keep dust out of your home.
Most London customers call us because a mortgage lender has refused to lend on a property with spray foam in the roof, or because a surveyor has flagged reduced property value. Others have hidden damp and rot behind the foam and never knew. If you have searched for closed cell foam removal near me London and been quoted silly money, we give you a fixed price after a free assessment, usually within 24 hours of your call.
Every closed cell spray foam removal job we quote includes the full strip-out, surface cleaning, dust control and waste disposal. There is no separate charge for the report or for the clean-up. If we find rot or damaged timbers, we will price the repair separately and only after you have seen the photos.
We remove all closed cell spray foam from rafters, roof decks and loft floors using reciprocating saws, oscillating multi-tools and hand tools. Nothing is left bonded to the timber that could fail a survey. Every rafter is checked individually before we move on.
After the bulk comes out, we clean the adhesive residue off with dry ice blasting or sand blasting media. This is what makes the timber look and test clean at survey. We do not gouge the wood, and we do not leave a sticky film behind.
Protective sheeting, a negative air machine and an air scrubber with HEPA filters run for the whole job. That keeps foam particles out of your living space. We also use an industrial vacuum for the final pass over the loft floor and joists.
All foam and debris goes into sealed disposal bags and leaves site with a licensed waste carrier. You get the waste transfer note for your records. Nothing goes into general waste and nothing gets left on your driveway.
You get before, during and after photos plus a written removal report. That is the document your lender, valuer or surveyor will ask for. We walk you round the loft at the end so you can see the timbers are clean before we pack up.
We visit, usually same day or next, and check the foam depth, the timber condition and the roof build-up. We use a thermal imaging camera to spot damp and cold bridging behind the foam. You get a fixed written price before we start, and we tell you honestly if the job is smaller or bigger than you thought.
On the day, we sheet up floors, walls and any loft hatch, then set a negative air machine and air scrubber with HEPA filters running. That keeps dust and foam particles out of your living space. Our technicians wear full respirators and protective clothing for the whole job.

Gets into corners, around noggins and behind services where a saw will not fit. Essential for the last few centimetres of foam that a surveyor will still flag if it is left behind.
Cleans adhesive residue off timbers without gouging the wood or leaving secondary media behind. Dry ice pellets lift the foam and sublimate, so there is nothing to sweep up afterwards.
Used on brick, stone and hard flat surfaces where abrasive media is the fastest route. We only use it where the substrate can take it and we mask everything around the work area.
Finds damp, cold bridging and hidden rot behind the foam before we start cutting. It tells us where to look and stops us opening up timbers that do not need it.

Ask a pro →We remove the foam, document every stage with photos, and give you a written report the lender and valuer can work from. We have unblocked sales across Wandsworth, Bromley and Barnet, often within a week of the first call.
Removing the foam lets us inspect every timber. We use a thermal imaging camera to find damp before we cut, treat any rot we uncover, and restore airflow through the eaves so the problem does not come back next winter.
Clean timbers and a documented removal report put your property back on a level footing with any other house on the street. We give you the paperwork a valuer needs, and we can talk to your surveyor directly if they have questions.
Once the foam is out, we clear the eaves, check the vents and confirm the roof can breathe again. We work to Building Regulations Part L and PAS 2035, so the ventilation is set up correctly rather than just opened up.
Most London lofts run between £1,800 and £4,500 in 2026, depending on the area covered and how hard the foam has set. A small terrace loft with 20 square metres of foam sits at the lower end. A large detached roof with 60 square metres, thick foam and timber repairs pushes towards the top. You get a fixed price after the free assessment, so there is no hourly billing.
Yes. We remove closed cell foam from lofts, attics, roofs, cavity walls and commercial units across Greater London. Closed cell foam sets hard, so we cut it out mechanically and finish the timbers with dry ice blasting or sand blasting media. If your foam is open cell spray foam, that is a different and usually quicker job, and we handle that too.
It is necessary when the foam is blocking a mortgage, hiding damp and rot, or stopping your roof from ventilating. Closed cell foam seals a roof solid, which traps moisture against the timbers. If a lender has refused to lend or a surveyor has flagged it, removal is the only fix. If none of those apply, we will tell you honestly that you may not need it.
A typical three-bed semi loft takes two to three days from set-up to final clean. Day one is containment and bulk removal, day two is surface cleaning and timber inspection, and day three is the report and handover if we need it. Larger roofs or foam that has bonded hard can run to four or five days. We give you a realistic timeline at the assessment.
