Loft spray foam removal in London is our core trade, and we handle it for homeowners, landlords and buyers across Greater London. If spray foam is blocking your mortgage, trapping damp or failing Building Regulations Part L, we take it out properly. We work with Icynene, BASF and Demilec foams, use thermal imaging cameras to map every patch, and leave your loft ready for modern insulation.
Loft spray foam removal in London is the controlled extraction of open cell or closed cell spray foam from your roof space, followed by cleaning, ventilation checks and disposal. It is needed when foam was applied too thickly, when it blocks roof ventilation, or when a surveyor flags it as a mortgage risk. We cut the foam back with reciprocating saws and oscillating multi-tools, bag it, and vacuum the dust with HEPA filters.
London homes are hit harder than most. Victorian terraces in Islington and Camden have tight roof voids where polyurethane foam traps condensation against rafters, and hidden damp and rot follow within a few winters. If you are searching for loft insulation removal near me London, we cover every borough. We also handle the paperwork side, because mortgage rejection due to spray foam is now a routine reason for sales falling through.
Every removal job includes the survey, dust control, extraction, cleaning and certification. We do not charge extra for thermal imaging or waste disposal. If your loft needs new insulation afterwards, we quote that separately so you can decide.
We inspect the foam, measure coverage and check ventilation with a thermal imaging camera. You get a fixed price the same day, with no obligation and no call-out fee.
Protective sheeting, a negative air machine and an air scrubber go in before any cutting starts. This keeps foam particles out of your living space and lets us work in occupied homes.

Technicians in respirators and protective clothing cut the foam into manageable sections with reciprocating saws and oscillating multi-tools.

Foam goes into disposal bags and leaves the site the same day, with waste transfer paperwork. We issue a removal certificate you can hand to your lender or surveyor. If you want new insulation fitted, we book that as a second visit.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Maps damp and hidden foam behind boards. It shows us where moisture has spread so we remove every affected patch, not just the visible areas.
Cuts dense closed cell foam into manageable sections without damaging rafters. The multi-tool handles tight corners where a full saw will not fit.
Uses dry ice pellets to freeze and lift adhesive residue from timber. It is abrasive-free, so it is safe on historic roof structures common in central London.
Captures fine foam dust and crumbs after extraction. HEPA filters stop particles escaping into your living space, which matters in occupied homes.

A three-bed Victorian terrace in Islington had closed cell foam sprayed across the entire roof void. The buyer's lender refused a mortgage, and the sale had stalled for six weeks. Dark patches on the rafters suggested damp had already taken hold.
We removed the foam in two days, cleared the ventilation paths and treated the affected timbers. The removal certificate went to the lender within a week, and the sale completed three weeks later. Moisture readings dropped from 22% to 12%.
A 1930s semi in Croydon had open cell foam blocking the eaves and a musty smell in the loft. The owner had noticed condensation dripping onto stored boxes every winter but did not realise the foam was the cause.
We extracted the foam in a day and a half, cleaned the timbers with HEPA vacuums and reinstated the ventilation. The loft dried out within three weeks, and the owner fitted new mineral wool insulation to Part L standards.
A developer converting a Hackney warehouse needed Icynene foam removed from exposed timber beams before building control would sign off. The foam had bonded hard to the beams and standard cutting tools risked marking the wood.
We used dry ice blasting to lift the adhesive residue without abrasives, then sanded and sealed the beams. The full job took three days, and building control signed off the following week. Waste transfer notes covered 1.2 tonnes of foam.
Spray foam causes more problems than most homeowners realise. By the time a surveyor flags it, damp and mortgage issues are already in play. Here is what we fix, and how.

Most London lofts cost between £1,800 and £4,500 in 2026, depending on foam type, coverage and access. A small terrace loft with open cell foam sits at the lower end; a large detached roof with closed cell foam and timber repairs sits higher. We give a fixed price after a free survey, so you know the total before we start.
Yes. We remove open cell and closed cell spray foam from lofts across every London borough, including Icynene, BASF, Demilec, Lapolla and Huntsman products. We use reciprocating saws, oscillating multi-tools and dry ice blasting to clear foam without damaging rafters.

It is necessary when foam blocks roof ventilation, traps damp or triggers a mortgage refusal. London's older roofs are especially prone to condensation behind closed cell foam. If a surveyor has flagged it, or you can see dark patches on rafters, removal is the safe route. We can assess it with a thermal imaging camera and tell you honestly whether it needs to come out.
A typical three-bed London loft takes one to two working days. Larger roofs, thick closed cell foam or heavy adhesive residue can push it to three days.
