Attic spray foam removal in London explained
Attic spray foam removal in London means taking out the polyurethane foam that was sprayed onto the underside of your roof tiles or between rafters, then cleaning the timber back to a surveyable condition. We use dry ice blasting machines, industrial vacuums and HEPA filters to lift the foam without gouging the wood. Most lofts we see in London were foamed between 2010 and 2018, and by now the foam has shrunk, cracked or trapped condensation against the roof deck.
London homeowners call us for three reasons: a mortgage lender has refused to lend on a spray-foamed property, a surveyor has flagged hidden damp and rot, or the loft is simply unusable because the foam blocks ventilation. We also handle attic insulation removal London wide for landlords who need an EPC upgrade before a new tenancy.

What's included
What our attic spray foam removal includes
Every removal job includes the full strip-out, clean and paperwork you need. We do not charge extra for disposal or protective equipment. The only add-ons are timber repairs if we find rot, and cavity wall extraction if foam was injected into the walls.
✓
Full foam strip-out
We remove all open cell and closed cell spray foam from the roof deck, rafters and purlins. No foam is left behind. We use dry ice blasting, saws and vacuum equipment to clear every surface.
✓
Timber clean and sand
After removal, we sand the rafters back to bare wood and vacuum the dust. This gives surveyors a clear view of the timber condition. Any minor mould is treated with a fungicidal wash.
✓
Ventilation check
We clear the eaves vents and check the breathable membrane is intact. Good airflow stops condensation forming on cold nights. If vents are blocked by insulation, we remove the obstruction.
✓
Waste disposal
All foam, dust and protective sheeting go into sealed disposal bags and leave the property the same day. We dispose of waste at licensed facilities and can provide a waste transfer note on request.
✓
Removal certificate
You get a certificate with before and after photos, thermal images and a PAS 2035 compliance statement. This is the document your lender or surveyor needs to release funds or sign off the sale.
How it works
How our attic spray foam removal works
01
Free loft survey
We visit your property, measure the foam coverage and take thermal images of the roof deck. You get a written report with photos and a fixed price the same day. Most surveys take 45 minutes and we cover all of Greater London.
02
Containment and protection
Before we cut anything, we lay protective sheeting over your floors and belongings, seal the loft hatch with negative air machines and set up an air scrubber. This keeps dust and foam particles out of your living space. We wear respirators and protective clothing throughout.
03
Foam removal
We use a dry ice blasting machine to freeze and crack the foam off the timbers, then an industrial vacuum with HEPA filters to capture the debris. For stubborn closed cell foam we switch to a reciprocating saw or oscillating multi-tool. A typical three-bedroom semi takes one to two days.
04
Timber clean and treatment
After the foam is gone, we sand the rafters back to bare wood and treat any signs of rot or mould. We check the roof membrane and clear the eaves vents. If we find damaged timbers, we can sister new sections alongside them.
05
Final inspection and report
We photograph the finished loft, run a final thermal scan and hand you a removal certificate for your lender or surveyor. We also give you a 5-year workmanship warranty on the removal. The whole job is usually complete within 48 hours of the survey.
Tools & methods
Tools and methods we use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Dry ice blasting machine
Freezes foam so it cracks off the timber without damaging the wood. It is the cleanest method for London lofts because it creates no secondary waste.
Industrial vacuum with HEPA filters
Captures fine foam dust and debris during removal. The HEPA filters stop particles escaping into your living space.
Thermal imaging camera
Finds hidden damp pockets and checks roof ventilation before and after removal. We use it to prove the loft is dry.
Reciprocating saw and oscillating multi-tool
Cuts through rigid closed cell foam in sections. These tools let us remove foam from awkward corners without damaging rafters.
Negative air machine and air scrubber
Creates negative pressure in the loft so dust and fumes are pulled out, not into your home. Essential for occupied properties.
Respirator and protective clothing
Protects our technicians from spray foam chemical hazards and dust. We wear full PPE on every job.
Protective sheeting and disposal bags
Covers your floors and belongings during removal. All waste goes into sealed bags and leaves the property the same day.
Real results
Before and after.
Victorian terrace in Islington
Before
The loft was filled with closed cell spray foam that had been installed in 2015. The buyer's lender refused a mortgage and the surveyor noted damp in three rafters. The foam blocked all eaves ventilation.
After
We removed the foam in two days using dry ice blasting and saws. The timbers were cleaned and treated, and the vents were cleared. The lender accepted our PAS 2035 report and the sale completed at full asking price.
1930s semi in Croydon
Before
Open cell foam had been sprayed between the rafters, causing condensation to drip onto the ceiling below. The homeowner noticed a musty smell and peeling paint in the back bedroom.
After
We cleared the foam in one day and ran a thermal scan to confirm the roof deck was dry. The condensation stopped immediately and the ceiling was repainted. The homeowner saved thousands compared to a full roof replacement.
Landlord portfolio in Hackney
Before
Three rental flats had spray foam in the lofts, and all three EPCs had dropped to an E rating. The landlord could not legally grant new tenancies without an upgrade.
After
We removed the foam from all three lofts in five days and provided removal certificates for each property. The energy assessor updated the EPCs to a C rating. The landlord re-let all three flats within a month.

It is necessary if you want to sell, remortgage or use the loft for storage. Spray foam traps condensation and blocks roof ventilation, which leads to rot. Most London lenders now refuse mortgages on foamed properties. Removing the foam and restoring airflow protects the roof structure and your property value.
A standard London loft takes one to two days to clear. Larger roofs or heavy closed cell foam can take three days. We work from 8am to 5pm and keep dust contained with air scrubbers. You can stay in the property while we work, and we clean up at the end of each day.
