About this service
What spray foam insulation removal in London, Greater London involves
spray foam insulation removal in London, Greater London is the controlled cutting, scraping and extraction of polyurethane foam from lofts, rafters and roof decks. We start with a thermal imaging camera survey to map coverage, then cut the foam into manageable blocks with a reciprocating saw and oscillating multi-tool.

Others have spotted loft condensation, damp patches or a musty smell and want it gone before rot sets in.

What's included
What our spray foam removal service includes
Every removal job includes the survey, the cutting and extraction, the clean-up and the disposal. We do not charge extra for the things that should be standard, like dust control or a written roof condition summary. Anything beyond removal, such as re-insulation or roof repairs, is quoted separately once you have seen what is under the foam.
✓
Thermal imaging survey
We map the foam coverage with a thermal imaging camera before quoting. This shows us where the foam is thin, where it is thick, and whether there are cold spots that suggest damp or missing insulation elsewhere in the roof.
✓
Dust-controlled cutting
Protective sheeting, a negative air machine, an air scrubber and HEPA filters go in before any cutting starts. Foam dust and particles are captured at source, so the rest of your home stays clean. This is standard on every job, not an optional extra.
✓
Full foam extraction
We cut out open cell and closed cell foam from rafters, roof decks and loft floors using reciprocating saws and oscillating multi-tools. Adhesive residue is scraped back so the timbers are clean and ready for inspection or a new insulation system.
✓
Rafter inspection report
Once the foam is off, we inspect the exposed timbers for damp, rot and insect damage. You get a written summary with photographs. This is the document most lenders and surveyors ask for when a mortgage has been held up by spray foam.
✓
Licensed disposal
All foam, bags and protective sheeting are removed from site and disposed of through licensed waste carriers. You do not need to hire a skip or arrange anything yourself. We provide waste transfer documentation on request.
How it works
How our spray foam removal process works
01
Survey and quote
We visit, measure the foam coverage, and check the roof structure with a thermal imaging camera. You get a fixed price before we start, not an estimate that creeps. Most surveys take 30 to 45 minutes, and we can usually book you in within a week.
02
Seal and protect
We lay protective sheeting over floors and belongings, then set up a negative air machine and air scrubber to keep dust and foam particles out of the rest of the house. Windows stay shut, and we seal the loft hatch. This stage takes about an hour on a typical London terrace.
03
Cut and extract
Using a reciprocating saw and oscillating multi-tool, we cut the foam into blocks and prise it away from the timbers. Open cell foam comes out faster than closed cell, which is denser and grips harder. A two-person crew clears an average loft in one to two days.
04
Clean and inspect
We vacuum every surface, scrape off adhesive residue, and inspect the exposed rafters for damp, rot or insect damage. If we find a problem, we photograph it and talk you through the options. You get a written summary of the roof's condition for your records.
05
Dispose and hand back
All foam, bags and protective sheeting are removed and disposed of through licensed waste carriers. We sweep the loft, refit the hatch, and walk you through the finished space. Most customers get their loft back the same day we finish cutting.
Tools & methods
Tools and methods we use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Thermal imaging camera
Maps foam coverage and reveals cold spots that suggest damp, missing insulation or hidden gaps in the roof structure before we quote.
Reciprocating saw and oscillating multi-tool
Cuts dense closed cell foam into blocks and prises it away from rafters with minimal damage to the timber. Bosch and Makita cordless tools are used where access is tight.
Industrial vacuum and air scrubber
Captures foam dust and particles at source. Combined with a negative air machine and HEPA filters, it keeps the rest of your home clean during removal.
Dry ice blasting machine
Removes stubborn adhesive residue and thin foam from delicate surfaces without abrasion. Dry ice pellets lift the foam and leave the substrate clean.
Sand blasting equipment
Strips foam and residue from brick, concrete and steel substrates where cutting is not practical. Used with full containment and controlled media.
Respirator and protective clothing
Standard issue for every operative. Spray foam dust and chemicals are a hazard, so we wear 3M respirators and full protective clothing throughout the job.
Real results

Hidden damp and rot in the rafters
Removal lets the roof breathe again. We inspect every rafter we expose and flag any decay. If rot is found, we photograph it and explain what repair is needed before you commit to anything.
Loft condensation and dripping
Once the foam is out, we clear blocked vents and restore a proper air path. This usually fixes the condensation at source. We also check that the roof void is properly ventilated before we leave.
Surveyor cannot inspect the roof
We remove enough foam to give full access to the roof structure, then document the condition. Surveyors can then complete their inspection. We can work to a deadline if your completion date is pressing.

Access, roof height and disposal also affect the price. We give you a fixed quote after a free survey, so you know the full cost before we start. Warehouse and commercial roofs are priced separately.
