What's included
What Our 24/7 Spray Foam Removal Includes
Every 24/7 Spray Foam Removal in London job includes the full extraction, timber check, disposal, and certification. There is no separate charge for night work, and no hidden extras for waste. The only add-ons are timber replacement if rot has gone too far, and new insulation if you want us to fit it after we finish.
Full Foam Extraction
We remove all accessible spray foam from rafters, felt, and roof timbers using cutting tools, reciprocating saws, and dry ice blasting. Bulk foam is bagged on site and removed the same day. Typical 3-bed terrace lofts take 6-10 hours with a two-person crew.
Timber Inspection and Treatment
Every rafter is checked with a moisture meter and a thermal imaging camera. Where readings are above 20 percent, we apply a fungicidal wash and timber treatments. We log the readings before and after so you have a record for your lender or surveyor.
Licensed Waste Disposal
Cured polyurethane foam is bagged, sealed, and taken to a licensed waste facility. You get a waste transfer note with your certificate. We do not leave foam bags on your driveway or in your wheelie bin - everything leaves with us.
Completion Certificate
You receive a written method statement, before-and-after photographs, moisture readings, and a completion certificate. This is the document your lender, surveyor, or buyer's solicitor needs to see. We format it for lender review and can send it directly to your broker.
Post-Job Ventilation Check
We confirm that eaves, vents, and loft openings are clear so air can move again. Trapped moisture is the root cause of most spray foam problems, and ventilation is the fix. You get a short brief on what to watch for over the next 30 days.
Service overview
24/7 Spray Foam Removal in London Explained
24/7 Spray Foam Removal in London is the controlled extraction of sprayed polyurethane insulation from lofts, roofs, and cavity walls, carried out at any hour of the day or night. Spray foam is applied as a liquid isocyanate and polyol resin mix that expands and cures hard, bonding to rafters, felt, and tiles. Removing it means cutting, scraping, or blasting the cured foam away without damaging the timber beneath, then bagging and disposing of every fragment. We use spray foam cutting tools, oscillating multi-tools, and reciprocating saws for the bulk of the work, then switch to dry ice blasting or sand blasting equipment for the stubborn residue left on rafters.
London homeowners call us for one of three reasons: a mortgage lender has refused a loan because of spray foam, a surveyor has found loft condensation and roof rot from trapped moisture, or the foam was installed badly and is now causing overheating in summer. Because so much of London's housing stock is Victorian and Edwardian terraces with breathable lime mortar and slate or clay tile roofs, trapped moisture does real damage fast. If you search for 24/7 spray foam removal in London near me at 2am, you'll reach a real person, not a call centre. We also cover emergency spray foam removal London Greater open now, seven days a week.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
How Our 24/7 Spray Foam Removal Works
The process flexes to the condition, but these checkpoints keep decisions clear.
Call and Triage
You call 020 8088 5347 at any hour. We ask four questions: where is the foam, how old is it, is there visible damp, and has a lender or surveyor flagged it. That takes under five minutes and lets us send the right crew with the right kit. You get a fixed price range before we hang up.
On-Site Assessment
A technician arrives, usually within 4 hours for emergency calls. They inspect the loft with a thermal imaging camera to map moisture pockets, take moisture meter readings on rafters, and check whether the foam is open cell or closed cell. You get a written scope and a confirmed price on the spot.
Controlled Extraction
We sheet the loft, set up dust extraction, and start cutting. Bulk foam comes off with oscillating multi-tools and reciprocating saws. Rafters are then cleaned with dry ice blasting or sand blasting equipment to remove adhesive residue. A typical 3-bed terrace loft takes 6-10 hours with a two-person crew.
Timber Treatment and Drying
Once the foam is gone, we treat any affected timbers with a fungicidal wash and apply timber treatments where rot has started. We leave vents and eaves clear so air can move again. Moisture readings are logged before we leave, and you get a copy for your records.
Certificate and Handover
We photograph every stage, write up the method statement, and issue a completion certificate. That document is what your lender, surveyor, or buyer's solicitor needs to see. We also give you a short verbal brief on what to watch for over the next 30 days, and you can call us back free if anything looks wrong.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Dry ice blasting machine
Freezes and lifts adhesive residue from rafters without abrasion. Used as the finishing pass after bulk cutting, it leaves timber clean and ready for treatment.
Sand blasting equipment
Reaches brick surfaces and hard-to-access rafters where cutting tools cannot go. We control the dust with extraction units and sheet the area before starting.
Oscillating multi-tool
Cuts cured foam away from rafters with depth guides to avoid gouging timber. The go-to tool for the bulk of open cell and closed cell extraction.
Reciprocating saw
Handles thick sections of closed cell foam that would stall a multi-tool. Used with a fine-tooth blade to keep the cut line clean and controlled.
Dust extraction unit
Runs throughout the job to capture airborne foam particles and dust. Essential in occupied homes, and it keeps the loft space safe for our crew.
Thermal imaging camera
Maps moisture pockets behind foam and boards before we start. It shows us exactly where the damp is sitting so we do not miss a hidden problem.
Moisture meter
Takes before-and-after readings on every rafter. Readings are logged and handed to you as part of the completion documentation.
Use cases
When London Customers Call Our 24/7 Service
These examples show how the service framework adapts rather than forcing every call through one repair.
Hackney Loft Roof Rot Stopped
A Hackney homeowner found damp patches on the ceiling below a loft that had been spray foamed in 2017. The foam had sealed the roof deck, and moisture had been condensing on the rafters for years. Six rafters had softened and one had visible mould growth. → We extracted the foam from 26 rafters over 10 hours, replaced the worst rafter, and treated the rest with fungicidal wash and timber treatments. Moisture readings fell from 28 percent to 14 percent. The ceiling dried out over two weeks and no further damp has appeared.
Croydon Rental Property Back to Lettable Standard
A landlord in Croydon had three rental properties with spray foam and recurring damp complaints from tenants. Two of the three had failed survey, and one had a void period of six weeks because the loft was unusable for storage. → We handled all three properties over a fortnight, removing open cell foam from each loft and logging moisture readings before and after. Two passed survey with no further work. The third needed two rafters replaced, which we completed within the same visit. All three are now let.
Problems we solve
Problems Our 24/7 Spray Foam Removal Solves
Spray foam causes a predictable set of problems in London homes. If any of these sound familiar, call us - we have seen them all before and we know how to fix them without making things worse.
Mortgage refusal due to spray foam
We remove the foam, inspect and treat the timbers, and issue a completion certificate formatted for lender review. Over 90 percent of our customers have had their mortgage offer reinstated after submitting our documentation. Most take two weeks from first call to certificate.
Loft condensation and roof rot from trapped moisture
We cut out the foam, dry the timbers, and apply fungicidal treatment where rot has started. Moisture readings typically drop from 22-28 percent to 12-16 percent within 48 hours. We also clear vents and eaves so the loft can breathe again.
Reduced property value and difficulty selling
Our removal and certification process removes the uncertainty. You get a documented, photographed record showing the foam is gone and the timbers are dry. That paperwork turns a problem property back into a sellable one.
Overheating in summer and damp and mould growth
Removing the foam restores airflow through the loft. We check for damp and mould growth in corners and behind boards, treat what we find, and leave the space ready for a breathable insulation system that performs in both summer and winter.
Pricing process
What 24/7 Spray Foam Removal Costs in London
£1,800 - £4,500 depending on loft size, foam type, and timber condition
Loft size and rafter count
A small 2-bed loft with 15 rafters takes half the time of a 5-bed house with 40. Most London terraces fall between 20 and 30 rafters, which is where our standard price range comes from. Larger lofts are quoted per rafter above 30.
Open cell vs closed cell foam
Open cell foam is softer and cuts faster, so it sits at the lower end of the range. Closed cell foam cures rock-hard and bonds aggressively to timber, adding roughly 30-40 percent to the labour time and the price.
Access and parking
A 600mm loft hatch and a permit-only street add time. We plan access and parking before the crew arrives, and we book suspensions where needed. There is no separate charge for this, but it can extend the job by an hour or two.
