Mortgage refused because of spray foam in the loft
We remove the foam, document the cleared timbers with photographs and provide a written summary your lender will accept. Most Carlisle jobs are cleared within a week of the first call.
sand blasting Spray foam insulation removal in Carlisle, Cumbria is what we do every week. If your loft is full of open cell or closed cell spray foam and your mortgage lender has flagged it, we blast it out, clean the timbers and leave the roof space ready for a surveyor. We cover City Centre, Botcherby, Currock and the rest of the Carlisle area, with same-day quotes and no hidden extras.

Sand blasting spray foam insulation removal is the controlled use of abrasive media, air pressure and industrial extraction to strip cured polyurethane foam off roof timbers, rafters and sarking boards. We use a sand blasting equipment rig paired with a negative air machine and air scrubber so dust stays inside the containment zone. The abrasive breaks the bond between foam and timber without gouging the wood, then an industrial vacuum pulls the debris out. It is the fastest way to clear open cell spray foam, closed cell spray foam and isocyanate-based foam from a loft or roof void.
Carlisle homeowners usually call us for one of three reasons: a mortgage refusal due to spray foam, loft condensation that has nowhere to escape, or roof timber rot spotted during a survey. The city's old sandstone and slate terraces in Denton Holme and Currock trap moisture, and foam sprayed directly onto cold sarking makes it worse. If you need sand blasting spray foam extraction near me Carlisle, we can usually assess the loft the same week and give you a fixed price before any equipment comes off the van.
Every job is quoted as a complete package. The price you agree after the survey covers the removal, the containment, the waste and the clean-down. There are no separate charges for equipment, disposal or a second visit if the foam is thicker than expected.
Sealed zone with sheeting, a negative air machine and an air scrubber running throughout. We protect your landing, stairwell and any rooms below before a single hose goes up.
Foam stripped from rafters, sarking and roof timbers using sand blasting equipment with media grade and pressure matched to the timber. We work in sections so debris never spreads.
Cables, pipework and downlights are cleared by hand with an oscillating multi-tool rather than blasted, so nothing electrical or plumbing-related is put at risk.
Every surface vacuumed, the loft floor swept, and all foam waste bagged and removed for licensed disposal. You get the loft back in a state a surveyor can walk into.
A full set of before-and-after photographs plus a written note of anything we found, such as rot or historic water ingress. This is the pack lenders and surveyors ask for.
A written warranty on the removal itself. If any foam is missed or the clean-down is not up to standard, we come back and put it right at no cost.
We inspect the loft, measure the foam coverage, check for loft condensation and roof timber rot, and photograph anything the lender will ask about. You get a fixed price the same day, usually within two hours of the visit. No charge for the survey.
On the day, we sheet the loft floor, seal the hatch and any penetrations, then position the negative air machine and air scrubber. The sand blasting equipment is set up outside the containment zone with hoses fed through. Setup takes 45 to 60 minutes on a typical Carlisle terrace.
We work in sections, blasting the foam off rafters and sarking and following immediately with an industrial vacuum. A 30 square metre loft takes three to five hours. Where foam has bonded to cables or pipework we switch to hand tools and an oscillating multi-tool to avoid damage.
Once the foam is off, we check every rafter with a thermal imaging camera and a moisture meter. If we find rot or historic water ingress we flag it with photographs so your surveyor or builder can price the repair. We do not cover problems up.
We vacuum the loft floor, bag all foam waste and remove it for licensed disposal. You get a photo record of the cleared space, a written summary of what we found, and a workmanship warranty on the removal itself. Most jobs finish before 4pm.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
The core rig for stripping cured foam off rafters and sarking. Pressure and media grade are set to the timber, not a generic setting.
Keeps the containment zone under negative pressure so dust and foam particles cannot escape into the rest of the house.
Filters airborne particles inside the loft throughout the job, so the air you breathe when you walk back in is clean.
Pulls blasted foam and media off the loft floor and out of gaps immediately behind the blasting, section by section.
Used around cables, pipework and downlights where blasting would be unsafe. Cuts and lifts foam away by hand.
Checks for damp, cold bridging and hidden moisture in timbers after the foam is off, before we sign the job off.
Worn by every technician inside the containment zone. Foam dust and isocyanate residue are not something to breathe.
A three-bed terrace with closed cell foam sprayed across every rafter. The buyer's lender refused the mortgage and the sale had stalled for six weeks. The loft was damp, the sarking was black with mould and the foam had wrapped around the original wiring.
We blasted the foam off over two days, hand-cleared the cables and vacuumed every surface. The moisture meter read normal across all timbers within 48 hours. The lender signed off on the photo pack and the sale completed three weeks later.
A large Edwardian house where foam had been sprayed onto the sarking in 2014. The loft smelled damp, stored boxes were mouldy and two rafters had visible rot. The owner wanted the foam gone before booking a roofer.
One day of blasting and extraction cleared 34 square metres of foam. The thermal imaging camera found two rafters with elevated moisture, which we photographed and reported. The roofer replaced both timbers the following week and the loft has stayed dry since.
A landlord with two post-war semis, both with open cell foam spread across the full loft. Tenants had complained of condensation and one property had failed an inspection. Both lofts needed clearing before new tenancies started.
We cleared both lofts in the same week, 28 and 31 square metres respectively, and provided a documentation pack for each property. Condensation complaints stopped and both units were re-let within a fortnight.
Foam that was sold as an energy fix often becomes the reason a house cannot be sold, remortgaged or kept dry. These are the problems we are called out to most often.

Blasting the foam off restores airflow through the roof void. We check moisture levels with a thermal imaging camera after removal and flag any timber that needs treatment.
We hand-clear cables and pipework with an oscillating multi-tool rather than blasting them, so the insulation and sheathing stay intact and your electrician can work on them later.
Once the foam is off we inspect every rafter and photograph anything suspect. You get an honest report you can hand to a builder or surveyor for pricing.
Most Carlisle lofts run between £1,800 and £4,500 in 2026, depending on foam type and coverage. A small open cell job under 20 square metres sits at the lower end; a full roof void with closed cell foam and difficult access sits at the top. We give you a fixed price after the survey, and there is no charge for the survey itself.
Yes, when it is done with the right containment and pressure settings. We seal the loft, run a negative air machine and air scrubber, and wear PPE respirators throughout. Abrasive media is matched to the timber so rafters are cleaned rather than damaged. Cables and pipework are protected or hand-cleared with an oscillating multi-tool.
Not when pressure and media grade are set correctly. We test a small area first, then adjust before working across the loft. Slate, sarking boards and softwood rafters all take blasting well. If a surface is fragile, we switch to dry ice blasting or hand tools instead, so the structure is never put at risk.
A typical 30 square metre loft takes one working day, usually three to five hours of blasting plus setup and clean-down. Larger roofs, or those with closed cell foam bonded to cables, can run into a second day. We tell you the expected duration in the quote so you can plan around it.
