Thermal spray foam removal in London clears failed open cell and closed cell spray foam from lofts, rafters and roof decks so your property can breathe again. We handle homes and commercial units across Greater London, from Victorian terraces in Islington to warehouse roofs in Barking. If a surveyor, lender or buyer has flagged the foam, we remove it, clean the timber and leave you with a roof you can actually sell.
Thermal spray foam removal in London is the controlled stripping of cured polyurethane foam from roof timbers, rafters and loft decks, followed by cleaning, ventilation checks and safe disposal. Foam that was sprayed years ago often hides rot, blocks airflow and traps condensation against the roof structure. Our technicians cut the foam back in sections, remove adhesive residue from the timber, and inspect what the foam was covering. Every job ends with a clean loft, a written summary of what we found, and photos you can hand to a surveyor or lender.
Most London customers call us because a mortgage lender has refused to lend on a foam-insulated roof, or because a surveyor has flagged hidden damp and rot. Foam sprayed between rafters stops the roof breathing, and in a city where loft condensation is already common, that is a serious problem. We also carry out thermal insulation removal London-wide for homeowners who simply want the foam gone before they sell. If you have been searching for thermal spray foam removal in London Greater London, our team covers every borough inside the M25.
Every thermal spray foam removal job includes the survey, the removal itself, full clean-up and the documentation your lender or surveyor needs. We quote as one fixed price, so you are not paying extra for waste disposal, dust control or paperwork. If we find rot or damaged timbers during the job, we tell you before we treat anything.
We visit your property, photograph the foam, identify whether it is open cell or closed cell, and check the roof structure with a thermal imaging camera. You get a fixed written price the same day, with no obligation and no charge for the visit.
We cut out all accessible spray foam from rafters, roof decks and loft floors using reciprocating saws, oscillating multi-tools and dry ice blasting. Adhesive residue is removed from the timber so the roof can dry and ventilate properly again.
Protective sheeting, negative air machines, air scrubbers and HEPA-filtered vacuums keep foam dust contained inside the work zone. Technicians wear respirators and protective clothing throughout. Your floors, furnishings and the rest of the property stay clean.
After removal we inspect the timbers for rot, damp and insect damage, photograph what we find, and give you a written summary of the roof condition. This is the document lenders and surveyors ask for when foam has been flagged on a mortgage application.
All removed foam goes into disposal bags and leaves site the same day. We transport it under our waste carrier registration and dispose of it through licensed routes. You do not need to hire a skip or arrange anything yourself.
We photograph the foam before we start and the clean roof structure when we finish. You receive both sets by email, which is useful for your records, for a future sale, or for showing an insurer that the work was completed to a proper standard.
We visit your property, photograph the foam, and check whether it is open cell or closed cell. Closed cell foam is denser and takes longer to cut back, so the quote reflects that. You get a fixed price the same day, plus a clear explanation of what we found and what needs removing. No charge for the survey.
Before any cutting starts we lay protective sheeting over floors, fix it to walls, and seal doorways. We set up a negative air machine and air scrubber so dust and foam particles stay inside the work zone. On occupied homes we work room by room and keep access clear, so you can still use the rest of the property while we are on site.
Technicians in protective clothing and respirators cut the foam back using reciprocating saws and oscillating multi-tools, working in sections so the roof structure never loses support. Stubborn patches and adhesive residue come off with dry ice blasting or sand blasting equipment. A typical loft takes one to two days; larger roof decks run to three or four.
Once the foam is gone we vacuum every surface with an industrial vacuum fitted with HEPA filters, then inspect the timbers for rot, damp or insect damage. Anything we find is photographed and logged. You get a written summary of the roof condition, which is exactly what surveyors and lenders ask to see before they sign off.
Foam waste goes into disposal bags and leaves site the same day, handled under our waste carrier registration. We do a final walkthrough with you, show you the before-and-after photos, and confirm the roof is ventilating correctly. If you want new insulation fitted afterwards, we can quote for that separately.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Lifts foam and adhesive residue off timber without water, chemicals or abrasive damage. Ideal for older or fragile roof structures where sand blasting would be too aggressive.
Used where foam has bonded hard to masonry or roof decks and dry ice cannot shift it. Always run with full containment and HEPA filtration so dust does not spread.
Reveals damp, cold bridging and hidden rot behind foam before we start cutting. It is how we tell the difference between foam that is sound and foam that is hiding a problem.
Keeps foam dust and particles inside the work zone. Essential on occupied homes where the loft sits directly above bedrooms and living space.
Cleans every surface after removal and captures fine foam dust that a standard vacuum would blow straight back into the air.
Cuts cured foam back in controlled sections without transferring vibration into the roof structure. The multi-tool gets into rafter gaps a saw cannot reach.
Foam dust and chemical residue are a genuine hazard. Our technicians wear full protective clothing and respirators for the entire removal, not just the cutting stage.
A three-bedroom Victorian terrace in Islington with open cell foam sprayed across the entire loft floor and rafters. The buyer's surveyor flagged the foam, and the lender refused to release funds until it was removed and the roof inspected.
We removed 38 square metres of foam over two days, cleaned the timbers, and found minor surface mould on two rafters which we treated. The lender received our condition report and photos, and the sale completed three weeks later.
A 1968 semi-detached house in Croydon with closed cell foam sprayed between the rafters roughly fifteen years ago. The owner had noticed a damp patch on the landing ceiling but had no idea how far the problem had spread.
We removed 52 square metres of closed cell foam over four days, replaced four rotten battens and treated the surrounding timbers. The thermal imaging camera confirmed the roof was drying out properly within a fortnight of completion.
A 1,400 square metre warehouse roof deck in Barking with foam sprayed across the full area. The building insurer had flagged the foam as a risk and the facilities team needed it gone without losing a day of operations.
We worked nights over five shifts, removed the foam with dry ice blasting and sand blasting, and cleared all waste the same week. The roof condition report went straight into the insurer file, and the building stayed fully operational throughout.
Spray foam causes a specific set of problems in London homes, and most of them only show up when you try to sell, remortgage or inspect the roof. Here is what we deal with every week.
Ask a pro →We remove the foam, inspect the roof structure, and provide a written condition report with photos that satisfies lenders and surveyors. Most clients are back in their lender's hands within a week of the work finishing.
Removing the foam exposes the full roof structure so we can see exactly what is wet and what is rotting. We treat affected timber, replace what is beyond saving, and restore ventilation so the roof dries out properly.
Once the foam is out we clear the eaves, check the vents and confirm air is moving through the roof again. That breaks the condensation cycle and keeps the loft dry through the winter months.
We remove the foam and document the exposed structure with photographs and a written summary. Your surveyor can then complete a full inspection, and your buyer has no reason to chip away at your asking price.
Typical 2026 pricing in London runs from £1,800 to £6,500 depending on roof size, foam type and access. A standard terraced loft with open cell foam usually sits at the lower end; a large detached roof deck with closed cell foam and rot treatment sits at the top. We give you a fixed price after a free survey, so you know the number before we start cutting.
Yes. We remove open cell and closed cell spray foam from lofts, rafters, roof decks and cavity walls across every London borough. Closed cell foam is denser and takes longer, but our technicians use reciprocating saws, oscillating multi-tools and dry ice blasting to strip it without damaging the timbers. We survey first, then confirm exactly what can be removed and how long it will take.
It is necessary when the foam is blocking roof ventilation, hiding damp and rot, or stopping you getting a mortgage. London roofs already deal with condensation through autumn and winter, and foam makes it worse by sealing the structure. If a surveyor or lender has flagged it, removal is the only fix that satisfies them. If the foam is sound and the roof is dry, we will tell you so.
A single loft takes one to two days. Larger roof decks, or jobs where we find rot that needs treating, run to three or four days. We work in sections so your roof stays supported throughout, and we clean as we go. You get a start date and a finish date in writing, and we stick to both.
