Service overview
What Closed Cell Spray Foam Removal in London involves
Closed Cell Spray Foam Removal in London is the mechanical and thermal extraction of cured polyurethane foam from roof decks, rafters, lofts and cavity walls. Unlike open cell spray foam, closed cell foam sets rock-hard and bonds aggressively to timber, tiles and masonry, so it cannot be scraped off by hand. Our technicians use spray foam removal saws, oscillating multi-tools, reciprocating saws and industrial vacuums to cut the foam back in controlled sections, then finish the surface with dry ice blasting or sand blasting equipment where the substrate is delicate. Every stage is contained with air scrubbers and PPE respirators to keep dust and isocyanate particles out of your living space. Most London customers call us after a surveyor flags spray foam insulation failing building regulations, or after a mortgage lender refuses to lend on a property with foam-packed rafters. In Greater London's older housing stock, closed cell foam traps moisture against roof timbers and accelerates rot, which is why so many sales fall through at the eleventh hour. If you have been searching for closed cell spray foam removal near me London and need a crew that understands both the building science and the lender's requirements, we can usually assess your property within 24 hours and start work the same week.
! Problems we solve
Mortgage lender refuses to lend on a foam-insulated property
The sale stalls, the chain collapses, and you are left paying for a survey that cannot progress until the foam is gone.
Roof timber rot from trapped moisture
Closed cell foam seals the roof deck, so condensation cannot escape. Rafters soften, battens fail and the repair bill climbs from hundreds into thousands.
Attic condensation and cavity wall damp from spray foam
Moisture condenses on cold surfaces behind the foam, soaking insulation, staining ceilings and encouraging mould through the colder months.

Dust-controlled extraction
We seal the work area, run air scrubbers and wear PPE respirators throughout. Foam is cut with saws and multi-tools, then finished with dry ice blasting where the substrate is delicate. Your furniture, carpets and stairwell stay protected from start to finish.

Timber inspection and photos
Once the foam is off, we inspect every rafter and batten for rot, damp and insect damage, treat what we find, and photograph the exposed structure. Those images are what your lender's surveyor needs to see before releasing a mortgage.

Spray foam removal saw
Cuts cured closed cell foam into manageable blocks without tearing the timber underneath. Blade depth is set per rafter so the wood stays intact.
Dry ice blasting machine
Freezes the adhesive bond between foam and substrate, so residue lifts off brick, felt and timber without abrasion or chemical residue.
Industrial vacuum and air scrubber
Captures foam dust and airborne particles at the source. Scrubbers create negative pressure in the work area to keep your living space clean.
Oscillating multi-tool and chisel set
Hand-finishes edges around rafters, pipes and cables where a saw cannot reach, and lifts the last of the bonded foam from awkward corners.
Local execution
London's housing stock makes closed cell spray foam removal a different job from elsewhere in the UK. Most of the properties we work on are Victorian and Edwardian terraces with shallow lofts, tight hatches and roof pitches that leave little room to swing a saw. Access is often limited to a single side of the building, so we plan containment and waste routes before the crew arrives. The damp London climate is the other factor: closed cell foam seals the roof deck, condensation has nowhere to go, and timber rot sets in faster here than in drier regions. We see it constantly in Islington, Hackney and Camden, and we treat every job as a moisture problem first and a foam problem second. If you have been quoted for closed cell insulation removal London-wide, ask whether the quote includes timber inspection and a Part L compliance check. Ours always does, because removing the foam without fixing the ventilation just moves the problem six months down the line.

How our closed cell foam removal works
Survey and quote
We visit your property, measure the foam coverage, check timber condition and photograph everything. You get a fixed written price the same day, with no hidden extras for access, waste or disposal. Most surveys take 45 to 60 minutes, and we can often combine the visit with an insulation assessment if you also want the loft rebuilt afterwards.
Containment setup
On arrival we seal doorways, lay protective sheeting and position air scrubbers to create negative pressure in the work area. This keeps foam dust and isocyanate particles out of your living space. Our crews hold CSCS cards and PASMA certification for safe work at height, and we set up edge protection before anyone steps onto a roof or into a loft hatch.
Foam extraction
Technicians cut the closed cell foam into manageable sections using a spray foam removal saw and oscillating multi-tool, then lever it free with a chisel and scraper set. Stubborn residue on rafters and brickwork is finished with dry ice blasting, which freezes the adhesive bond so the foam releases without gouging the timber. A two-bedroom loft typically takes one to two days.
What closed cell foam removal costs
Typical 2026 pricing for closed cell spray foam removal in London runs from £1,200 for a small loft to £4,500 or more for large roof decks and commercial spaces. A standard two-bedroom terrace loft usually lands between £1,800 and £2,600, including containment, extraction, timber inspection, waste disposal and the final report. The variables that move the price most are foam depth, access, and how much of the roof structure is affected. We quote fixed prices after survey, so the number you accept is the number you pay unless we find something unexpected and agree it with you first.
Foam depth and coverage
Thick foam applied across a full roof deck takes longer to cut and produces more waste than a thin layer between a few rafters. Depth is measured at survey and priced per square metre, so you can see exactly what drives the cost.
Access and roof height
Tight loft hatches, single-side access and steep pitches slow the work and require more containment. Where PASMA towers or edge protection are needed, that is included in the quote rather than added later.
Timber condition and reinstatement
If rot or insect damage is found once the foam is off, replacing rafters or battens adds cost. We photograph the evidence, agree the extra work with you before proceeding, and quote insulation reinstatement separately so you can decide when to do it.
Frequently asked questions
How much does closed cell spray foam removal cost in London?
Typical 2026 pricing in London runs from £1,200 to £4,500 depending on loft size, foam depth and access. A standard two-bedroom terrace loft usually falls between £1,800 and £2,600. Roof decks with thick foam, fragile tiles or restricted access cost more because they take longer and need more containment. Commercial units and warehouses are quoted per square metre after survey.
Can you remove closed cell spray foam in London?
Yes. We remove closed cell spray foam from lofts, roof decks, rafters and cavity walls across every London borough. Closed cell foam is dense and bonded hard to timber, so it needs saws, multi-tools and dry ice blasting rather than hand scraping. We have cleared foam installed by BASF, Dow, Huntsman, Soudal and Recticel systems, and we document the exposed timbers for your lender.
Is closed cell spray foam removal difficult in Greater London?
It is more difficult than open cell removal because closed cell foam sets rigid and grips timber aggressively. In Greater London the challenge is compounded by older roof structures, tight loft hatches and terraces where access is limited to one side. That is why the job needs specialist tools and PASMA-certified crews. Done correctly, it takes one to three days for a typical residential loft.
How long does closed cell spray foam removal take in London?
Most residential lofts take one to three working days from containment setup to clean-down. Larger roof decks, cavity wall foam and commercial spaces can run four to seven days. We confirm the schedule at survey and hold to it. If you need same day closed cell spray foam removal London-wide because a survey or completion date is looming, call us and we will tell you what is possible.
