What's included
What Our Residential Removal Service Includes
Every residential spray foam removal job includes the survey, the extraction, the waste disposal and the completion report. There is no separate charge for the documentation your lender needs, and no hidden disposal fee at the end. Here is exactly what you get.
Pre-Work Survey
A 45-minute site visit with a thermal imaging camera and moisture meter. We measure foam coverage, check timber moisture, and identify whether the foam is open cell or closed cell before quoting. You get the fixed price the same day.
Full Foam Extraction
Cutting, prying and vacuuming of all accessible spray foam from rafters, eaves and roof deck. We use dust extraction units and sealed bags throughout, so foam dust stays in the loft and out of your living space.
Timber Condition Report
Photographic evidence of every rafter and roof deck section after foam removal, with moisture readings logged. If we find structural timber damage or rot, you get a clear note on what needs treatment before new insulation is fitted.
Waste Disposal
All foam, dust and debris removed from site in sealed bags and disposed of through licensed waste routes. You receive a waste transfer note with the completion pack, which matters if your lender or buyer asks for proof of proper disposal.
Lender-Ready Completion Pack
A single document containing before-and-after photos, product details, moisture readings and a summary of work carried out. Brokers and underwriters accept it as evidence that the spray foam issue has been resolved.
Service overview
What Residential Spray Foam Removal in London Involves
Residential Spray Foam Removal in London is the controlled cutting, extraction and disposal of spray-applied polyurethane insulation from lofts, rafters and roof decks. We start with a thermal imaging camera and moisture meter survey, because foam that looks fine on the surface often hides loft condensation underneath. Then we cut the foam into manageable sections with an oscillating multi-tool and reciprocating saw, bag it, and run a dust extraction unit to keep spores and isocyanate dust out of your living space.
Most London homeowners call us for one of three reasons: a mortgage lender has refused a loan because of spray foam, the loft is overheating in summer, or roof timbers are showing damp and mould growth. Victorian terraces in Islington and Hackney are the usual suspects, because original rafters were never designed to carry closed cell spray foam. If you have searched for residential spray foam removal in London near me and found only vague quotes, we give you a fixed price after a 45-minute survey.
The service timeline
How Our Removal Process Works
The process flexes to the condition, but these checkpoints keep decisions clear.
Survey and Quote
We visit, measure the foam coverage, and check timber moisture with a moisture meter. You get a fixed written price the same day, usually within four hours of the visit. No deposit is taken until you accept the quote.
Site Protection
We lay dust sheets, seal the loft hatch with a zipped barrier, and set up a dust extraction unit vented outside. Your carpets and furniture stay clean. On terraced houses we also protect the party wall edges before any cutting starts.
Foam Extraction
Foam is cut into sections with an oscillating multi-tool and a reciprocating saw, then pulled away from the rafters by hand where it is brittle. Stubborn adhesive residue is removed with dry ice blasting or sand blasting equipment, depending on the substrate.
Timber Inspection
Once the foam is out, we inspect every rafter and the roof deck for structural timber damage, rot and insect activity. You get photos of anything we find, plus a clear note on what needs treatment before new insulation goes back.
Clearance and Report
All foam, dust and debris leave site in sealed bags the same day. We hand over a completion report with before-and-after photos, moisture readings and a summary you can pass to your lender, surveyor or buyer.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Oscillating multi-tool
Cuts foam cleanly away from rafters and around pipework without splitting the timber. It is the first tool we reach for on every loft job.
Reciprocating saw
Used on thick closed cell foam where hand tools will not get through. We control depth carefully to avoid scoring the roof deck underneath.
Industrial vacuum and dust extraction unit
Captures foam dust, spores and debris at the point of cutting. Vented outside the property, it keeps your living space clean throughout the job.
Dry ice blasting machine
Removes adhesive residue and thin foam films from timber without abrasives or water. Ideal for older London roofs where the rafter surface needs to stay intact.
Thermal imaging camera and moisture meter
Used at survey and again after removal. The camera finds hidden damp behind foam, and the meter gives us a before-and-after reading for the completion report.
PPE respirator and full containment sheeting
Protects our technicians from isocyanate dust and keeps the loft sealed from the rest of the house. Every crew member wears a fitted respirator for the full shift.
Use cases
When to Book Residential Spray Foam Removal
These examples show how the service framework adapts rather than forcing every call through one repair.

Damp Loft Dried Out in Croydon
A 1960s semi in Croydon had open cell foam between the rafters and a loft that smelled damp every winter. The owner had noticed mould growth on the roof deck and was worried about the timber. Two previous contractors had quoted without surveying the roof properly. → We extracted the open cell foam in a day and a half, found two rafters with early rot, and flagged them with photographs. Moisture readings dropped from 24 percent to 14 percent over six weeks. The owner had the rafters treated and new insulation fitted.
Overheating Solved in Wandsworth
A 1930s semi in Wandsworth had spray foam applied across the whole loft by a previous owner. The top-floor bedrooms became unusable in summer, with temperatures over 30 degrees Celsius, and the owner was considering air conditioning. → We removed 28 square metres of foam, reinstated a vapour barrier and fitted insulation batts to current standards. Summer loft temperatures dropped by roughly 6 degrees Celsius, and the owner cancelled the air conditioning quote. The work took one day.
Problems we solve
Problems We Solve for London Homeowners
Spray foam rarely causes one problem. It causes a chain of them, and each one gets more expensive the longer it is left. These are the issues we are called out to fix most often across London.
Mortgage refusal due to spray foam
We remove the foam, photograph the timbers, and issue a completion report formatted for underwriters. Most lenders accept it as proof the issue is resolved, and your broker can send it directly to the valuation team without further site visits.
Loft condensation and damp patches
We clear the foam, open the eaves ventilation, and check the roof deck for trapped moisture. Once air can move again, the loft dries out naturally. We log moisture readings before and after so you can see the difference in numbers.
Roof rot from trapped moisture
Our survey includes a moisture meter check on every rafter. If we find rot, we flag it in the timber condition report with photos, so you can get a carpenter in before new insulation goes back. We do not cover up problems we find.
Overheating in summer
Removing the foam and reinstating a breather membrane with insulation batts restores a balanced roof. Heat escapes as it should, and the loft stays usable through the summer. Most customers notice the difference in the first warm spell.
Pricing process
What Residential Spray Foam Removal Costs
1,800 - 4,500 pounds depending on scope
Foam type and thickness
Closed cell foam is denser and bonds harder to timber, so it takes longer to cut out than open cell foam. Foam over 100mm thick can add half a day to a standard loft and pushes the price toward the upper end of the range.
Loft size and coverage
We price by square metre of foam coverage, not by house size. A 20 square metre loft with partial foam is a smaller job than a 45 square metre roof deck with full coverage, even if the houses look similar from the street.
Access and parking
Tight loft hatches, no rear access and restricted parking all add labour time. If we can park close and carry equipment straight in, the job runs faster and the price reflects it.
How much does residential spray foam removal cost in London?
Most London lofts cost between 1,800 and 4,500 pounds in 2026, with the average around 2,600 pounds. Price depends on foam thickness, roof access, whether the foam is open cell or closed cell, and how much timber treatment is needed afterwards. We give you a fixed quote after a 45-minute survey, so you are not guessing from a phone description.
Do you offer domestic spray foam removal in London Greater?
Yes. We cover all 32 London boroughs plus the City, from Barnet and Hillingdon in the west to Havering and Bexley in the east. Domestic spray foam removal in London Greater is our core work, and we run same-week surveys across most postcodes. If you are outside the M25, call us and we will confirm coverage before booking.
Is home spray foam removal covered by insurance in London?
Rarely. Most home insurance policies exclude spray foam problems because the foam was installed rather than damaged by an insured event. A few policies cover removal when the foam was fitted by a contractor who misrepresented the product. We provide the documentation your insurer needs, but you should check your policy wording before assuming cover.
How long does residential spray foam extraction take in London?
A standard 40 square metre loft takes one working day, roughly seven to eight hours on site. Larger roof decks, cathedral ceilings or heavily oversprayed timbers can run to two or three days. We confirm the expected duration in your quote so you can plan access, parking and any time away from the property.
