Service overview
What an Insulation Removal Service in London, Greater London involves
An Insulation Removal Service in London, Greater London is the controlled strip-out of failed, damp or non compliant insulation from lofts, rafters, cavity walls and roof voids, followed by full waste removal and a clean, breathable structure. We cut and pull spray foam away from timbers, vacuum out loose fill, bag everything, and leave the space ready for new insulation or a building surveyor's inspection. Nothing gets left behind in your loft. Most London jobs we take on start with a mortgage lender refusal due to spray foam, or a surveyor flagging attic condensation from spray foam that has trapped moisture against the rafters. Others are simple upgrades: homeowners in Camden and Hackney pulling out 1970s mineral wool before fitting modern boards. If you have been searching for an insulation removal service near me London and want a firm that turns up when it says it will, we cover every postcode inside the M25 and most of the surrounding boroughs.
! Common warning signs
Mortgage lender refuses to proceed because of spray foam
Your sale stalls, the chain collapses and you may lose your buyer entirely. Lenders treat non compliant loft insulation as a structural risk until it is removed and documented.
Roof timber rot from trapped moisture
Foam seals the rafters so condensation cannot escape. Untreated rot spreads along purlins and can reach the point where structural repair is the only option, costing thousands more than removal.
Cavity wall damp from spray foam
Foam injected into a cavity can bridge the gap and trap water against the inner leaf. You get damp patches on internal walls, blown plaster and rising repair bills if the cavity cannot drain.
Scope of work
What our insulation removal service in London includes
Every strip-out we quote covers assessment, containment, removal, cleaning and waste disposal. If you want new insulation fitted afterwards, or timber treatment for rot, we price that separately so you can see exactly what you are paying for.
-
01
Free loft assessment
We inspect the loft or cavity, identify whether you have open cell or closed cell foam, mineral wool or loose fill, and check for moisture damage. You get photos, a written scope and a fixed price the same day. No charge, no obligation to book.
-
02
Dust containment setup
Dust sheets on the access route, a zipped barrier around the loft hatch and air scrubbers running throughout the job. Foam dust is an irritant and we keep it out of your living space. Bedrooms below the loft stay usable while we work.
-
03
Full removal and cleaning
Foam is cut from rafters with a spray foam removal saw and oscillating multi-tool, loose fill is vacuumed out, and every timber is scraped and brushed by hand. We check for roof timber rot and flag anything that needs treatment before new insulation goes in.
-
04
Waste disposal and paperwork
All waste is bagged, removed through the property and taken to a licensed facility. You receive a waste transfer note, dated before-and-after photos and a written summary of what was removed. That pack is what surveyors and mortgage valuers ask to see.
Why London homeowners book our insulation extraction service
Failed insulation does not fix itself. It holds water, blocks ventilation and quietly rots the timbers above your head. Here is what changes once it is out.
Get a quoteTools and methods we use on every strip-out
Spray foam removal saw
Cuts dense closed cell foam into liftable sections without levering against the rafters. We control depth so the blade does not score the timber underneath, which is critical on older London roof structures.
Oscillating multi-tool
Gets into corners, rafter bays and tight junctions where a saw will not reach. Used with a scraper blade to lift foam bonded to brick, felt and tile edges without cracking the surrounding material.
Industrial vacuum with HEPA filtration
Pulls foam crumbs, loose fill and dust straight into a sealed container rather than letting it settle in your loft. HEPA filtration is what keeps fine particles out of the bedrooms below while we work.
Air scrubber
Runs continuously during the strip-out to filter airborne dust and foam particles inside the containment zone. It is the reason we can work in occupied homes without you needing to move out for the duration.
Local execution
London roof voids are not like the rest of the country. Most of the housing stock is Victorian and Edwardian terraces with shallow lofts, narrow hatches and rafters that have already taken decades of weather. Add the damp air that sits over the Thames corridor and you get the conditions we see every week: foam that has trapped moisture, felt that has gone brittle, and eaves vents blocked by insulation pushed into the gap. Building Regulations Part L and PAS 2035 both expect a breathable structure, and a foam-filled loft rarely meets that test. If you need an insulation extraction service London wide, we work to those standards on every job. We also check for asbestos in pre-2000 properties before we cut anything, and we phase work around occupied homes so families are not displaced.

How our insulation strip out service works
Free assessment
We visit, measure the loft or cavity, identify whether you have open cell spray foam, closed cell spray foam or mineral wool, and check for moisture damage. You get photos, a written scope and a fixed price the same day. Most assessments take 30 to 45 minutes.
Protect and seal
On the day, we lay dust sheets, seal the loft hatch with a zipped barrier and set up an air scrubber so dust and foam particles do not drift into your bedrooms. A two-person crew handles most lofts; larger roofs get three. Setup takes about 45 minutes.
Cut and extract
We slice foam away from rafters with a spray foam removal saw and oscillating multi-tool, then lift it in sections so we do not lever against the timbers. Loose fill and foam crumbs go straight into an industrial vacuum. A typical 40 square metre loft takes one to two days.
What insulation removal costs in London
Typical 2026 pricing in Greater London runs from 900 pounds for a small open cell loft to 3,000 pounds for cavity wall extraction on a larger terrace. Warehouse roofs are quoted per square metre. The number depends on loft size, foam type, access and how much timber damage we find. You get a fixed written price after a free assessment, so the figure does not move unless you ask us to do extra work. We are not the cheapest quote you will get, and we are not trying to be.
Loft size and foam type
A 25 square metre open cell loft is a one-day job. The same space filled with closed cell foam bonded to rafters can take two days because it has to be cut in sections. Price scales with square metres and how hard the foam has cured.
Access and containment
Narrow hatches, loft conversions and homes where the access route runs through finished rooms add time and protection work. We seal the hatch, sheet the stairs and run air scrubbers, which is slower than an empty loft but keeps your home usable.
Timber damage and ventilation
If we find roof timber rot or blocked eaves vents, we flag it and quote separately for treatment or ventilation work. Removing the foam is the first step; making sure the structure can dry is what stops the problem coming back.
Insulation removal questions answered
How much does an insulation removal service cost in London?
Most London loft strip-outs cost between 900 pounds and 2,400 pounds in 2026, with cavity wall extraction running 1,200 to 3,000 pounds. Price depends on loft size, foam type, access and how much timber damage we find. Closed cell foam bonded to rafters takes longer than loose mineral wool. You get a fixed written price after a free assessment, so there is no hourly billing.
What does an insulation removal service do in London?
It removes failed, damp or non compliant insulation from your loft, rafters or cavity walls, then cleans the void and disposes of the waste. We cut spray foam off timbers, vacuum out loose fill, scrape residue from brick and tile, and document the finished space with photos. The result is a breathable structure ready for new insulation or a mortgage valuation.
Is insulation removal service safe in Greater London?
Yes, when it is done by trained crews with the right equipment. Cured polyurethane foam is not toxic, but cutting it releases dust that irritates lungs and eyes, and older foam can contain isocyanate residue. Our technicians wear PPE respirators, seal the loft hatch, and run air scrubbers so dust stays out of your living space. We also check for asbestos in properties built before 2000.
How long does insulation removal service take in London?
A standard 40 square metre loft takes one to two working days. Cavity wall extraction on a typical terraced house runs two to three days because we work in sections and inspect the wall ties as we go. Larger roofs, warehouse units or heavy closed cell foam can take four to five days. We confirm the timeline in writing after the assessment.
