What's included
What our Commercial Spray Foam Removal includes
Every commercial job includes survey, extraction, timber inspection, waste disposal and a completion pack. Reinstatement of insulation and vapour barrier is included as standard. Additional timber treatment or structural repairs are quoted separately if needed.
Free site survey
We attend your London property within 24 hours, inspect the foam with a thermal imaging camera and moisture meter, and check the roof structure. You get a fixed written price the same day, broken down by area. No charge and no obligation.
Controlled foam extraction
We cut and remove all spray foam using oscillating multi-tools, reciprocating saws and industrial vacuums. Dust extraction units with HEPA filters keep the rest of the building clean. Adhesive residue is cleared with dry ice blasting or sand blasting where needed.
Timber inspection and treatment
Every rafter and joist is checked for rot, damp and structural damage. We record moisture readings and photograph anything that needs attention. Affected timbers are treated with preservative as part of the job, and we tell you if any need replacing.
Insulation and vapour barrier reinstatement
We fit new insulation batts and install a correct vapour barrier to current standards. This restores thermal performance and stops moisture getting back into the structure. Materials are BBA approved and covered by manufacturer warranties.
Waste removal and documentation
All foam waste is bagged, labelled and removed to a licensed transfer station the same day. You receive waste transfer notes, before-and-after photos, moisture readings and material certificates in a single completion pack that lenders and surveyors accept.
Service overview
What Commercial Spray Foam Removal in London actually involves
Commercial Spray Foam Removal in London is the controlled extraction of polyurethane foam, adhesive residue and contaminated insulation batts from commercial roofs, lofts and cavity walls, followed by reinstatement of a compliant vapour barrier. We cut the foam with oscillating multi-tools and reciprocating saws, pull it out with industrial vacuums and dust extraction units, then check every timber with a moisture meter and thermal imaging camera before we sign the job off.
London commercial buildings are hit harder than most. Roofs on Victorian warehouses in Hackney and Shoreditch trap condensation because the original vapour barrier is gone, and isocyanate foam sprayed in the 1990s and 2000s has now cracked, gone brittle or soaked up damp. We see mortgage refusal due to spray foam on nearly every commercial refinance, plus roof rot from trapped moisture on older stock. That is why commercial spray foam removal London landlords book most often follows a failed lender survey.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
How our spray foam removal process works
The process flexes to the condition, but these checkpoints keep decisions clear.
Survey and quote
We attend your London site within 24 hours, inspect the foam with a thermal imaging camera and moisture meter, and check the roof structure. You get a fixed written price the same day, broken down by area. No charge for the survey, no obligation to book.
Site protection
Before any cutting starts we seal doorways, lay protective sheeting and set up dust extraction units with HEPA filtration. Our technicians wear full PPE respirators. On occupied offices in the City of London we often work evenings and weekends so staff are not disrupted.
Foam extraction
We cut the foam into manageable sections with oscillating multi-tools and reciprocating saws, then pull it out with industrial vacuums. Stubborn adhesive residue on rafters is cleared with dry ice blasting or sand blasting equipment. A typical 200 square metre roof takes two to three days.
Timber inspection
Once the foam is gone we inspect every rafter and joist for rot, damp and structural damage. We record moisture readings and photograph anything that needs treatment. If timbers are sound, we move straight to reinstatement. If not, we tell you exactly what needs replacing and why.
Reinstatement and sign-off
We fit new insulation batts, install a correct vapour barrier and treat any exposed timber. You get a completion pack with before-and-after photos, moisture readings and material certificates. Most jobs are signed off within five working days of starting.
Tools & methods
Tools and methods we use for spray foam extraction
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Oscillating multi-tool
Cuts open cell and closed cell foam into manageable sections without damaging the timber underneath. Ideal for detailed work around rafters, pipework and roof windows.
Reciprocating saw
Powers through dense closed cell foam and thick adhesive layers. Used on larger commercial roofs where speed matters and access is straightforward.
Industrial vacuum and dust extraction unit
Captures foam dust and debris at the point of cutting. HEPA filters keep the rest of the building clean, which matters for occupied offices and retail units.
Dry ice blasting machine
Clears adhesive residue from rafters without abrasion. It is the preferred method for older or listed London buildings where the timber surface must be preserved.
Sand blasting equipment
Strips foam residue from brick and concrete surfaces where hand tools cannot reach. Dust is controlled with extraction units and protective sheeting.
Thermal imaging camera and moisture meter
Identifies hidden damp, trapped moisture and cold spots before and after removal. Every commercial job includes a full set of readings in the completion pack.
PPE respirator and full protective kit
Protects our technicians from isocyanate dust and airborne particles. Every crew member wears a fitted respirator, coveralls, gloves and eye protection for the full shift.
Use cases
When London businesses call us for spray foam removal
These examples show how the service framework adapts rather than forcing every call through one repair.
Canary Wharf office damp resolved
An office loft had open cell foam that was trapping damp and setting off moisture alarms. Ceiling patches were appearing above the server room. The building could not close for the work. → We worked evening shifts over four days, removing the foam and fitting new insulation with a correct vapour barrier. Moisture readings returned to normal and the alarms stopped. No business days were lost.
Croydon retail units cleared for sale
Three retail units had spray foam that was voiding the building warranty and blocking a sale. The buyer's solicitor wanted proof the defect was cleared before completion. → We cleared all three units in under a week and issued a separate completion pack for each, including waste transfer notes and material certificates. The sale completed without further delay.
Problems we solve
Problems our London spray foam removal solves
Failed spray foam causes more than damp. It blocks finance, voids warranties and drags down property value. Here are the most common problems we fix for commercial clients across Greater London.
Mortgage refusal due to spray foam
We remove the foam, document timber condition with moisture readings and provide a lender-ready completion pack. Most clients are back on track within three weeks. We have cleared foam for dozens of London refinances that had been stuck for months.
Roof rot from trapped moisture
We strip the foam, dry the structure and treat affected timbers with preservative. A moisture meter and thermal imaging camera check every rafter. If rot has gone too far, we tell you exactly which timbers need replacing and why.
Voided building warranty
Removal and correct reinstatement restores the warranty position. We work to BBA approved methods and provide material certificates and completion documentation. Your surveyor can confirm the defect is cleared before completion.
Overheating in summer
Once the foam is removed and a correct vapour barrier fitted, the roof space vents properly again. Most units see summer temperatures drop noticeably. One Camden office recorded a 6 degree reduction in loft temperature after reinstatement.
Pricing process
What Commercial Spray Foam Removal costs in London
2,400 - 12,000 depending on scope
Roof area and foam thickness
The bigger the roof and the thicker the foam, the longer extraction takes. A 100 square metre roof with 50mm foam is a one-day job. A 500 square metre roof with 150mm closed cell foam can take a week.
Foam type
Open cell foam is softer and faster to remove. Closed cell foam is dense and bonds hard to timber, so it takes longer and uses more equipment. Closed cell jobs typically cost 20 to 30 percent more.
Access and roof height
High roofs, tight streets and restricted parking add time and equipment costs. We use mobile platforms where scaffolding is not practical. Access is assessed at the survey and built into the fixed price.
How much does commercial spray foam removal cost in London?
Most commercial spray foam removal in London costs between 2,400 and 4,800 pounds for a 150 square metre roof, including extraction, waste disposal and reinstatement. Larger warehouses run 6,000 to 12,000 pounds. Access, roof height and foam thickness are the biggest price drivers. We give you a fixed written price after a free survey, so there are no day-rate surprises.
