Closed cell spray foam removal in Bath
Specialist extraction for lofts, roofs and cavity walls across Somerset
If you need closed cell spray foam removal in Bath, our team cuts out hard polyurethane foam that traps moisture, blocks roof ventilation and stalls mortgage valuations. We work across Bath and Somerset on lofts, roofs, cavity walls and commercial units, using dry ice blasting and HEPA-filtered extraction to clear the foam without wrecking the timbers underneath. Call 0122 528 5137 for a same-week assessment.
What closed cell spray foam removal in Bath involves
Closed cell spray foam removal in Bath is the controlled cutting, breaking and extraction of high-density polyurethane foam from roof decks, lofts, cavity walls and floor voids. Unlike open cell foam, closed cell foam sets rock-hard and bonds to timber, so it cannot be scraped off by hand. We use reciprocating saws, oscillating multi-tools and dry ice blasting to fracture the foam, then pull the debris out through a dust extraction unit with HEPA filtration. Every rafter, joist and felt layer is inspected afterwards with a boroscope inspection camera and moisture meter before we sign the job off.
Most Bath callers come to us for one of three reasons: a mortgage lender has flagged spray foam on a survey, the foam is trapping moisture and rotting roof timbers, or a loft conversion needs the old insulation stripped back to bare structure. Period properties around Combe Down, Widcombe and Larkhall are the usual suspects, because solid stone walls and slate roofs leave nowhere for damp to escape once foam seals the deck. If you have been searching for closed cell spray foam removal near me Bath, we cover the whole city and surrounding Somerset villages.
Why Bath homeowners book closed cell foam extraction
Removing hard spray foam is rarely optional. It is the difference between a saleable property, a dry roof and a loft you can actually use. Here is what changes once the foam is out.
Unblocks your property sale
Mortgage refusal due to spray foam is the single biggest reason we get called out in Bath. Lenders treat closed cell foam on roof decks as a hidden defect, and valuers will down-value or decline until it is gone. We provide photographic before-and-after evidence and a written method statement your solicitor can pass straight to the lender.
Stops trapped moisture and rot
Closed cell foam seals a roof deck so tightly that condensation has nowhere to go. Within two to three winters, rafters can show damp staining and early rot. Removing the foam restores airflow through the loft, and we treat any affected timber before we close the job out.
Restores roof ventilation
Building regulations expect a ventilated cold roof. Foam sprayed directly onto the underside of slate or tile kills that gap. Once we have stripped the foam back, we can reinstate vents, felt laps and eaves gaps so the roof performs the way it was designed to.
Makes the loft usable again
Hard foam eats headroom and hides wiring, pipework and chimney breasts. After extraction, a loft in Oldfield Park or Bear Flat becomes a clean, inspectable space again, ready for boarding, a conversion or a straightforward insulation upgrade such as Kingspan or Recticel boards.
How our closed cell foam removal process works
Every job follows the same five stages, from first phone call to final inspection. You will know what is happening on each day and what it costs before we start.
Survey and quote
We visit your property, usually within 48 hours of your call, and inspect the foam with a boroscope inspection camera and thermal imaging camera. You get a fixed written price the same week, covering extraction, disposal and making good. No hourly rates, no surprise extras halfway through.
Protect and prepare
On day one we lay dust sheets and protective sheeting across floors, stairs and any furniture left in place. We seal doorways and set up a dust extraction unit with HEPA filter vacuum at the loft hatch so dust and foam particles stay inside the work zone. Most lofts take two to three hours to prepare.
Cut and extract the foam
Technicians in PPE respirators cut the closed cell foam into manageable sections using reciprocating saws and oscillating multi-tools. Stubborn patches bonded to rafters come off with dry ice blasting, which freezes the foam so it fractures cleanly instead of tearing the timber grain. A typical three-bedroom roof takes one to two days.
Inspect and treat timbers
With the foam gone, we check every rafter and joist with a moisture meter. Any damp or early rot gets treated with a fungicidal wash and, where needed, sistered timbers. We photograph the bare structure so you have a dated record for your lender or surveyor.
Clear up and sign off
We bag all foam waste and remove it under a licensed waste transfer note, then vacuum the whole area twice. You get a completion pack with photos, the waste note and our workmanship warranty. Most customers are back using the loft the same evening we finish.
Why choose our closed cell spray foam removal in Bath
Plenty of firms will cut foam out. Fewer will do it without damaging your roof, and fewer still will hand you the paperwork your lender actually accepts. Here is what separates our Bath team.
Lender-ready documentation
We supply dated photographs, moisture meter readings, a method statement and a licensed waste transfer note with every job. Bath solicitors and valuers have accepted our packs for remortgages and sales on dozens of occasions, which saves you a second survey fee.
Foam out, roof intact
Closed cell foam grips timber hard. Our technicians use dry ice blasting and controlled saw work to break the bond rather than rip it, so rafters, felt and battens survive the process. We have never had to replace a roof deck purely because of how we removed the foam.
Local to Bath, not a call centre
We are based in Bath and cover Somerset, so a closed cell foam removal service Bath homeowners can actually reach means we are often on site within 48 hours of your call. You deal with the same team from survey to sign-off, and you can reach us on 0122 528 5137.
Affordable, fixed-price work
Affordable closed cell spray foam removal Bath Somerset pricing means a fixed quote before we start, based on loft size, foam thickness and access. No hourly billing, no charge for the survey, and no add-ons for dust sheets, waste disposal or the completion pack.
What our closed cell foam removal includes
Every closed cell spray foam removal in Bath we carry out includes the survey, the extraction, the clean-up and the paperwork. There are no hidden extras for dust protection or waste disposal. The only additions are optional upgrades such as timber treatment or new insulation, which we price separately before you commit.
Full pre-work survey
We inspect the foam with a boroscope inspection camera and thermal imaging camera, measure thickness, and check for damp with a moisture meter. You get a fixed written quote and a clear method statement before any work starts.
Dust-controlled extraction
Dust sheets, protective sheeting and a dust extraction unit with HEPA filter vacuum keep foam debris out of your living space. We seal the work zone at the loft hatch and vacuum twice on completion.
Timber inspection and treatment
Once the foam is off, we check every rafter and joist for moisture and early rot. Affected timbers are treated with a fungicidal wash, and we photograph the bare structure for your records.
Licensed waste removal
All foam waste is bagged and removed under a licensed waste transfer note. You receive a copy with your completion pack, which lenders and solicitors often ask to see.
Completion pack and warranty
You get dated photographs, moisture readings, the waste transfer note and our workmanship warranty in one document. It is the evidence pack that keeps mortgage valuations moving.
Problems our closed cell foam removal solves
Hard spray foam causes a predictable set of problems in Bath properties. Recognising them early saves timber, money and a failed house sale.
Mortgage lender refuses to lend on a foamed roof
Your sale or remortgage stalls, the buyer walks, and you may face a down-valuation even if you find another lender.
We remove the closed cell foam, photograph the bare structure and supply a licensed waste transfer note. Bath solicitors and valuers accept our completion pack, so the lending decision can be revisited without a second full survey.
Trapped moisture rotting roof timbers
Closed cell foam seals the deck, so condensation soaks into rafters and battens. Left for two or three winters, timber rot spreads and roof repairs become structural.
Our technicians cut the foam back, dry ice blast the bonded residue, and check every timber with a moisture meter. We treat early rot on the spot and restore ventilation so the roof can dry out properly.
Loft unusable because of hard foam
Foam sprayed between rafters eats headroom, hides wiring and pipework, and blocks any plan for boarding or a loft conversion.
We strip the foam back to bare timber and clear the debris, leaving a clean, inspectable loft. From there you can board, convert or fit modern insulation such as Kingspan or Recticel boards.
Spray foam smell and fumes in living space
Poorly applied foam can off-gas for months, leaving a chemical smell in bedrooms below the loft and causing headaches for occupants.
Removing the foam at source eliminates the smell. We extract the material with HEPA-filtered equipment, ventilate the loft, and confirm the air is clear before we sign the job off.

Tools and methods we use
Tools & Equipment
Dry ice blasting machine
Fires dry ice pellets at the foam to freeze and fracture it away from rafters without tearing the timber grain. It is our first choice on slate roofs.
Reciprocating saw
Cuts thick closed cell foam into manageable sections between rafters. Blades are changed frequently to keep cuts clean and avoid overheating the timber.
Oscillating multi-tool
Reaches into corners, around chimney breasts and along wall plates where a full saw will not fit. Ideal for detail work in older Bath lofts.
HEPA filter vacuum
Captures fine foam dust and debris at source. Paired with a dust extraction unit, it keeps the work zone and the rest of your house clean.
Boroscope inspection camera
Lets us see behind rafters, under felt laps and inside cavity walls before and after extraction, so nothing is missed.
Thermal imaging camera
Maps foam thickness and finds hidden damp patches that a visual inspection would miss. It shapes the quote and the method statement.
Moisture meter
Reads timber moisture content before and after removal. We record the numbers and pass them to you in the completion pack.
Methods
Dry ice blasting extraction
Dry ice pellets at around minus 78 degrees Celsius freeze the closed cell foam so it becomes brittle and releases from timber. We apply it in controlled passes, then vacuum the fractured material. It is the least damaging method for the felt and battens on Bath slate roofs.
Controlled saw cutting
For thick foam, we cut the material into blocks with reciprocating saws and oscillating multi-tools, working bay by bay. This keeps the loft structurally stable during removal and makes bagging and removal straightforward.
HEPA-filtered containment
We seal the work zone with protective sheeting and run a dust extraction unit with HEPA filtration throughout. Airborne foam particles are captured rather than spread through the house.
Timber treatment and ventilation reinstatement
After extraction, we treat any damp or early rot with a fungicidal wash and reinstate eaves vents, felt laps and ventilation gaps so the roof performs as a cold roof again.
How closed cell foam removal runs in Bath
Bath's building stock makes closed cell foam removal harder than in most cities. Victorian terraces, Georgian townhouses and stone cottages around Combe Down, Widcombe and Larkhall were built with slate roofs and solid walls, and they rely on airflow through the loft to stay dry. Once closed cell foam seals the deck, that airflow stops. Add the Somerset climate, with damp winters and humid summers, and you get condensation soaking into rafters within two or three heating seasons. Access is the other local factor. Many Bath lofts are reached through narrow hatches, steep staircases or roof windows, so we plan extraction routes carefully and use compact equipment where a full-size machine will not fit. We also work to the ventilation requirements expected under current building regulations, reinstating eaves gaps and felt laps as part of the job. If you need closed cell foam extraction in Bath Somerset, we will tell you honestly whether the foam can be removed in place or whether part of the roof covering needs to come off first.
Service Areas
Stone-built cottages with slate roofs where foam often seals the deck completely. We plan extraction around narrow loft hatches and steep access.
Victorian terraces with shared party walls. We coordinate with neighbours where access or dust control crosses a boundary.
A mix of period and 1930s housing. Foam here is often bonded hard to older rafters, so dry ice blasting is usually the right method.
Dense terraced streets with limited parking. We schedule deliveries and waste removal to keep the street clear.
Listed and conservation-area properties where roof coverings must be handled carefully. We work with your consent requirements in mind.
Local Considerations
Damp Somerset winters and humid summers
Condensation builds quickly behind sealed foam, so we always check timber moisture before and after extraction and treat anything above safe levels.
Slate roofs on period properties
Slate and old felt are fragile. Dry ice blasting lets us remove foam without the impact damage that scraping or heavy blasting would cause.
Narrow loft hatches and steep access
We break equipment down into sections and use compact extraction units so we can work in tight Bath lofts without removing roof coverings.
Conservation areas and listed buildings
External changes may need consent. We keep works inside the roof wherever possible and advise on what, if anything, needs approval.
Combe Down loft stripped in two days
A stone cottage loft was fully sealed with closed cell foam between every rafter. The buyer's lender had declined the mortgage, and two rafters showed damp staining near the eaves.
We removed 14 square metres of foam over two days, treated the two affected rafters and restored eaves ventilation. Moisture readings dropped from 24% to 14% within three weeks.
Maintenance & Follow-up
Keep eaves vents clear and check the loft once a year for any new damp staining. If you re-insulate, use breathable boards rather than foam.
A Victorian terrace loft was unusable because foam had been sprayed across the rafters and around the chimney breast, hiding old wiring and blocking the planned conversion.
The foam was cut and blasted out in a day and a half, wiring was exposed and made safe, and the rafters were left clean enough for the builder to start on schedule.
Maintenance & Follow-up
Have the new conversion insulated with a breathable system and keep the loft hatch sealed to stop warm air migrating into the roof space.
A landlord's rental loft had foam trapping moisture into three rafters. Tenants had complained about a musty smell, and the insurer wanted evidence of remedial work.
We extracted the foam, treated the timbers and supplied before-and-after moisture readings plus a waste transfer note. The smell cleared within a week and the insurer closed the claim.
Maintenance & Follow-up
Check the loft each autumn for damp patches and keep the eaves vents free of insulation. Report any new staining early rather than waiting for a survey.
How much does closed cell spray foam removal cost in Bath?
Typical 2026 pricing in Bath runs £1,800 to £4,500 for a standard three-bedroom roof, and £600 to £1,400 for a single loft bay or cavity wall section. The final figure depends on foam thickness, how much timber needs treating and access. We survey first and give you a fixed written price, so the number you agree is the number you pay.
Can you remove closed cell spray foam in Bath, Somerset?
Yes. We remove closed cell spray foam across Bath and the whole of Somerset, including Combe Down, Widcombe, Larkhall, Odd Down and Twerton. Hard foam needs mechanical cutting and dry ice blasting rather than scraping, and our technicians are trained for both. Most lofts are cleared in one to two working days.
Is closed cell foam extraction near me available in Bath?
It is. We cover every Bath postcode and surrounding Somerset villages, and we can usually survey within 48 hours of your call. For urgent cases, such as a mortgage valuation deadline, we offer 24/7 closed cell foam removal Bath bookings and can often start work the same week.
What is the best method for closed cell spray foam removal in Bath?
Dry ice blasting combined with controlled saw cutting is the best method for closed cell foam. Dry ice freezes the foam so it fractures away from timber without tearing the grain, and a HEPA filter vacuum captures the debris. On slate roofs common in Bath, this approach protects the felt and battens that scraping would destroy.
