Service overview
Spray Foam Removal near me in London explained
Spray Foam Removal near me in London is the controlled extraction of cured polyurethane foam from lofts, roof slopes, cavity walls and commercial units, followed by cleaning and making good so the structure can dry and be re-insulated correctly. Foam sprayed between rafters traps moisture against roof timbers, and once it hardens it will not come out with a scraper and a bin bag. We cut it back in sections, vacuum the dust at source, and check the timber underneath before we call the job done. Most London call-outs start the same way. A surveyor flags spray foam insulation failing building regulations, a mortgage lender refuses to lend, or a homeowner finds roof timber rot from trapped moisture after a leak. In a city where roughly half the housing stock predates 1945, foam sprayed onto old rafters and lath ceilings causes real damage fast. If you have been searching for local spray foam removal London Greater London homeowners can actually get booked in, we cover the whole of Greater London and can usually survey within 48 hours.
! Common warning signs
Mortgage lender refuses to lend because of foam
Your buyer pulls out, the chain collapses and you are back to viewings with a property that surveyors keep flagging. Every week of delay costs you money and momentum.
Roof timber rot from trapped moisture
Foam sprayed between rafters stops the roof breathing. Damp collects, timber softens and rot spreads along purlins and battens until the structure needs proper carpentry work.
Attic condensation and damp patches
Water beads on the underside of foam, drips onto stored belongings and stains ceilings below. Left alone it soaks insulation, feeds mould and makes the loft unusable for storage.

Why London homeowners book us

Book a surveyTools and methods we use
Spray foam removal saw
Cuts thick closed cell spray foam into manageable sections without tearing at the rafters. It is the first tool out of the van on most lofts and does the bulk of the work.
Oscillating multi-tool
Trims foam back flush against timbers, pipes and cables where a saw cannot reach. It gives us the control to clear awkward corners without nicking services or splitting rafters.
Industrial vacuum and air scrubber
Captures foam dust at the extraction point and filters the air in the work zone. Running both keeps the rest of your London home usable while we cut.
PPE respirator and coveralls
Cured isocyanate foam releases fine particles when cut, so every technician wears a fitted respirator, coveralls, gloves and eye protection. It is non-negotiable on every job.
Local execution
London's housing stock makes foam removal a different job from anywhere else in the country. Roughly half the homes here were built before 1945, with lath and plaster ceilings, unvented roof voids and rafters that were never designed to carry a layer of closed cell foam. Add the damp, mild winters and driving rain off the Thames, and foam that seals a roof becomes a moisture trap fast. We work with that reality every week, from Georgian conversions in Westminster to post-war estates in Hounslow. If you need spray foam extraction near me London homeowners can trust, we survey, remove and report to a standard that satisfies lenders, surveyors and Building Control. We also handle the practical side of London jobs: parking suspensions, narrow loft hatches, shared access in mansion blocks and listed-building constraints. For anyone searching for cheap spray foam removal near me London, we will always tell you honestly whether the foam actually needs to come out, because in some cases targeted ventilation is enough.

How our removal process works
Survey and quote
We visit, measure the foam coverage, check the timber and confirm whether it is open cell or closed cell. You get a fixed price the same day, usually within 4 working hours of the survey. If the foam is cosmetic and the timber is sound, we will tell you straight rather than sell you a removal you do not need.
Protect the property
On arrival we lay dust sheets, seal doorways and the loft hatch, and set up the air scrubber. Our technicians wear a PPE respirator and full coveralls because cured isocyanate foam releases fine particles when cut. Setup takes 30 to 45 minutes on a standard house and keeps the rest of your home usable.
Cut and extract the foam
We use a spray foam removal saw and oscillating multi-tool for the bulk, then a chisel and scraper set for the last few millimetres against the rafters. A reciprocating saw handles thicker closed cell sections. Extraction runs at roughly 8 to 12 square metres a day on a typical loft, with the industrial vacuum running continuously.
What foam removal costs in London
Typical 2026 pricing in London runs from 900 to 3,500 pounds for a domestic loft, and from 4,000 pounds upwards for commercial roofs. The variables are foam type, coverage, access and how much timber work is needed afterwards. We give you a fixed written price after the survey, and the survey itself is free. If you have been hunting for cheap spray foam removal near me London, be careful: the lowest quote often means cutting corners on dust control or skipping the timber inspection, and that costs more later.
Foam type and coverage
Closed cell spray foam is denser and bonded harder than open cell, so it takes longer to cut and generates more waste. A 20 square metre closed cell loft can take two days, while the same area of open cell may come out in one.
Access and working height
Narrow loft hatches, shared stairwells and steep roof pitches all slow the job down. Work at height needs PASMA-certified access equipment, and listed or heritage buildings may need gentler methods such as dry ice blasting.
Timber condition and repairs
If we find rot, beetle or damp staining, the affected timbers need treatment or replacement before re-insulation. We photograph everything and quote any carpentry separately so you can see exactly what is being charged for.
