About this service
What environmentally friendly insulation removal in London, Greater London involves
Environmentally friendly insulation removal in London, Greater London is the controlled extraction of spray foam insulation from lofts, roofs, and cavity walls using low-dust methods and responsible disposal. We start with a thermal imaging camera survey to map the foam and check for hidden damp. Then we isolate the area with protective sheeting and negative air machines, cut the foam with reciprocating saws and oscillating multi-tools, and bag it for recycling or energy recovery. HEPA filters and air scrubbers keep dust out of your living space.
Most London homeowners call us because a mortgage lender has refused a loan on a spray-foam-insulated property, or because roof ventilation issues have caused condensation and rot. The city's older housing stock, especially Victorian terraces in Islington and Hackney, traps moisture in roof voids once foam seals the timbers. We also work in newer builds where open cell spray foam was applied too thickly. Whether you need eco insulation removal London-wide or a same day environmentally friendly insulation removal London appointment, we can usually survey within 24 hours.

How it works
Our five-step removal process
01
Free survey
We visit your property, usually within 24 hours of your call. Using a thermal imaging camera and moisture meter, we map the foam, check for damp, and measure the area. You get a fixed written quote the same day, with no hidden extras.
02
Site protection
On arrival, we lay protective sheeting over floors and furniture. We set up negative air machines and air scrubbers with HEPA filters to contain dust. All technicians wear respirators and protective clothing. This stage takes 30 to 60 minutes depending on loft size.
03
Foam extraction
We cut foam using reciprocating saws and oscillating multi-tools, then break it into manageable blocks. For stubborn adhesive residue, we use dry ice blasting machines or sand blasting equipment with eco-friendly media. An industrial vacuum collects debris as we work. A typical loft takes one to two days.
04
Timber inspection
Once foam is removed, we inspect rafters and joists for rot or insect damage. If we find problems, we treat the wood with preservative and replace any unsound sections. We photograph everything for your records. This step usually adds half a day.
05
Clean-up and certificate
We bag all foam waste and remove it from site. The loft is vacuumed and wiped down. You receive a removal certificate and before/after photos, which you can share with your mortgage lender or building control. The whole job is typically complete in two to three days.
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
Detects hidden damp and maps foam coverage without cutting. We use it during the survey to plan the removal.
Dry ice blasting machine
Freezes and cracks foam using CO2 pellets. Leaves no chemical residue and is safe around wiring. Ideal for delicate areas.
Industrial vacuum with HEPA filters
Collects dust and small foam particles during cutting. HEPA filters trap fine particles, keeping your home clean.
Negative air machine and air scrubber
Creates negative pressure in the work zone, so dust does not escape into living areas. Essential for occupied homes.
Reciprocating saw and oscillating multi-tool
Cuts through foam blocks and adhesive. We use Bosch and Makita models for reliability and control.
Sand blasting equipment
Strips stubborn foam and adhesive from brick or timber. We use eco-friendly media that can be recycled.
