Open cell spray foam removal in Bath done right, first time
Specialist extraction for lofts, roofs and cavity walls across Somerset
If you need open cell spray foam removal in Bath, our team cuts out soft, moisture-heavy foam and restores your loft or roof space to a clean, mortgageable condition. We work across Somerset on homes where failed open cell foam has trapped damp, blocked ventilation or stalled a sale. Most jobs are surveyed within 48 hours and cleared in one to three days.
What open cell spray foam removal in Bath involves
Open cell spray foam removal in Bath means physically cutting out soft, low-density polyurethane foam from rafters, loft floors and roof decks, then cleaning the timber back to a sound, breathable surface. Open cell foam is the spongy, expanding type that lets water vapour pass through it, so once it gets wet it stays wet. We remove it in sections, bag it, and inspect every rafter for trapped moisture and rot before we sign the job off.
Bath homes are especially prone to this problem. The city's older stone and brick housing stock sits in a damp valley climate, and open cell foam sprayed between rafters often blocks the ventilation path that a traditional cold roof needs. We regularly remove open cell spray foam from lofts in Bath where homeowners have been refused a mortgage, and we also handle open cell foam extraction in Bath Somerset for landlords and housing associations who need a fast, documented clearance.
Why Bath homeowners book our foam extraction
Removing failed open cell foam is rarely just about insulation. It is about getting your roof space back to a state a surveyor, lender or buyer will accept, and stopping damp from spreading into the timbers.
Mortgage and survey ready
Lenders routinely refuse mortgages on Bath properties with open cell foam in the roof. We remove the foam, document the timber condition and provide a clearance summary your surveyor can work from. Most clients get their valuation reissued within two weeks of the job finishing.
Stops trapped moisture and rot
Open cell foam holds water against rafters for years. We use a moisture meter and boroscope inspection camera to find wet timbers before they soften, then remove the foam and treat affected sections. Catching it early saves thousands compared with replacing rotten structural timber.
Restores roof ventilation
A cold roof needs airflow from eaves to ridge. Foam sprayed tight to the felt blocks that path and causes condensation. After extraction we clear the ventilation gap and check the roof space with a thermal imaging camera so you can see the difference in airflow and surface temperature.
Clean, low-dust removal
We seal the loft opening with protective sheeting, run a dust extraction unit and HEPA filter vacuum, and bag all foam on site. Most Bath properties are left broom-clean the same day, with no foam debris in bedrooms or hallways below.
Our open cell foam removal process
Every job follows the same five stages, from the first survey to the final clearance check. You will know what is happening on each day and who is on site.
Survey and assessment
We inspect the loft or roof space, measure foam depth and coverage, and test timber moisture with a moisture meter. You get a written scope, a fixed price and a realistic start date, usually within 48 hours of your call.
Protection and setup
On day one we lay dust sheets and protective sheeting, seal the loft hatch and set up a dust extraction unit with HEPA filter vacuum. Our technicians wear PPE respirator masks throughout, and we keep walkways clear so you can still use the house.
Foam extraction
We cut the open cell foam into manageable sections using a reciprocating saw and oscillating multi-tool, then lift it away by hand with a chisel and scraper set. A typical three-bedroom Bath loft takes one to two days to clear completely.
Timber clean and inspection
Once the bulk foam is out we clean residual material from the rafters, check every timber with a boroscope inspection camera, and treat any early rot. We photograph the cleared structure so you have a record for your lender or buyer.
Clearance and handover
We vacuum the space, remove all waste, and walk you through the finished roof space. You receive a clearance summary, before-and-after photos and advice on ventilation and any replacement insulation you may want to add.

Our team works across Bath and the surrounding villages every week, from Bathwick to Combe Down. That means short travel times, quick surveys and no waiting weeks for a slot. Most open cell spray foam removal Bath jobs are booked within five working days.
Fixed pricing, no surprises
You get a written price after the survey and it does not change unless you ask us to add work. We quote affordable open cell spray foam removal Bath Somerset pricing based on loft size, foam depth and access, so you can compare quotes fairly.
Lender-friendly documentation
Mortgage refusal due to spray foam is the single biggest reason people call us. We photograph the cleared timbers, record moisture readings and provide a clearance summary that surveyors and lenders accept. That documentation is included in every open cell insulation removal Bath job.
Clean, careful extraction
Open cell foam is soft and dusty, so containment matters. We use protective sheeting, a dust extraction unit and HEPA filter vacuum on every job, and we bag all waste on site. Your home is left clean, and we can arrange same-day or 24/7 open cell foam removal Bath call-outs for urgent sales.
What our open cell foam removal includes
Every open cell spray foam removal in Bath starts with a full survey and ends with a documented, clean roof space. The items below are included as standard. Replacement insulation, plaster repairs and damp-proofing work are quoted separately if you need them.
Full loft or roof survey
We measure foam coverage and depth, test timber moisture with a moisture meter, and check ventilation paths with a boroscope inspection camera. You get a written scope and fixed price before any work starts.
Contained foam extraction
We seal the work area with protective sheeting, run a dust extraction unit and HEPA filter vacuum, and cut foam out with a reciprocating saw and oscillating multi-tool. All foam is bagged on site and removed the same day.
Timber clean and inspection
After extraction we scrape residual foam from rafters, inspect every timber for rot, and treat any early decay. We photograph the cleared structure so you have a record for your lender, surveyor or buyer.
Ventilation check
We confirm the eaves-to-ridge airflow path is clear and check roof space temperatures with a thermal imaging camera. If ventilation needs improving, we explain the options and quote separately.
Clearance documentation
You receive before-and-after photos, moisture readings and a written clearance summary. This is the paperwork lenders and surveyors ask for when a mortgage has been held up by spray foam.
Waste removal and disposal
All foam, dust and debris are removed from your property and disposed of through licensed waste routes. We leave the loft broom-clean and ready for whatever insulation or storage you want to add next.
Problems our open cell foam removal solves in Bath
Open cell foam causes a predictable set of problems in Bath homes. Here are the ones we see most often, and how we fix them.
Mortgage refused because of spray foam
Your sale stalls, your buyer walks away and you lose months of progress. Lenders treat spray foam in the roof as a structural and moisture risk until it is removed and documented.
We remove the foam, record timber moisture and provide a clearance summary with photos. Most Bath clients get their valuation reissued within two weeks, and we can prioritise urgent sale deadlines with same-day or 24/7 call-outs.
Trapped moisture and rotting timbers
Open cell foam holds water against rafters for years. Left alone, timbers soften, fixings lose grip and roof structure repairs can run into thousands of pounds.
We test every timber with a moisture meter and boroscope inspection camera, remove the foam, treat early rot and flag anything structural. Catching it at the damp stage avoids full timber replacement.
Damp smells and condensation in the loft
Blocked ventilation traps humid air, which condenses on cold surfaces and drips onto stored items. Over time, mould spreads across rafters and ceiling joists.
We clear the foam, restore the eaves-to-ridge ventilation path and check surface temperatures with a thermal imaging camera. Most lofts are noticeably drier within days of extraction.
Difficulty selling or remortgaging
Surveyors flag open cell foam as a defect, and buyers use it to negotiate thousands off the asking price. Without documentation, you are stuck in limbo.
Our clearance pack gives buyers and lenders what they need: photos of cleared timbers, moisture readings and a written summary. We also remove foam from lofts in Bath for landlords preparing properties for sale.
When to book open cell foam removal
A buyer's surveyor has flagged open cell foam in the loft and the mortgage is on hold.
We survey within 48 hours, remove the foam in one to two days, and issue a clearance summary your lender can review. We prioritise these jobs because we know the clock is ticking on your sale.
Most buyers get their valuation reissued within two weeks, and the sale completes without a price reduction for foam removal.
You have owned the property for years and the loft smells damp, with staining on ceilings below.
We test timber moisture, remove the open cell foam and check ventilation with a thermal imaging camera. Any early rot is treated before we hand the space back.
The damp smell clears, ceilings stop staining and the roof space becomes usable for storage again.
You are a landlord with foam in multiple rental properties and need documented clearance for your records.
We handle open cell foam extraction in Bath Somerset across multiple addresses, with consistent reporting and waste documentation for each property. Work is scheduled around tenancies.
You get a clear paper trail for every property, fewer damp complaints from tenants and easier future sales.
Foam was sprayed tight to the roof felt and you are worried about condensation and rot.
We inspect with a boroscope inspection camera, cut the foam back from the felt and restore the ventilation gap. If the felt is damaged, we explain the repair options and quote separately.
Airflow is restored, condensation drops and the risk of long-term timber decay is significantly reduced.
Tools and methods we use
Tools & Equipment
Reciprocating saw
Cuts open cell foam into manageable sections between rafters without damaging the timber. It is our primary extraction tool on most Bath loft jobs.
Oscillating multi-tool
Used for precision cuts around pipes, cables and tight corners where a larger saw will not fit. It lets us remove foam cleanly without nicking services.
Dust extraction unit and HEPA filter vacuum
Captures airborne dust and foam particles during cutting and cleaning. We run both on every job to keep the rest of your home dust-free.
Boroscope inspection camera
Lets us see behind rafters and into closed cavities to check for hidden moisture, rot and foam residue before we sign off the job.
Thermal imaging camera
Shows cold spots and moisture patterns across the roof structure. We use it on surveys and again after extraction to confirm ventilation has improved.
Moisture meter
Gives a precise reading of timber moisture content. We test every accessible rafter and record the results in your clearance documentation.
Chisel and scraper set
Removes residual foam and adhesive from timber surfaces after the bulk material is cut away. Essential for getting rafters back to a clean, breathable finish.
Methods
Mechanical section removal
We cut open cell foam into sections with a reciprocating saw and lift it away by hand. This method is fast, low-dust and suitable for the soft, low-density foam found in most Bath lofts.
Dry ice blasting
For historic timbers and delicate surfaces, dry ice pellets freeze foam residue so it lifts away without abrasive damage. We use it selectively where the original timber must be preserved.
Abrasive blasting
Sand blasting equipment and abrasive blasting media strip stubborn foam from brick, stone and hard-to-reach surfaces. All dust is contained with sheeting and extraction.
Containment and HEPA filtration
We seal the work area with protective sheeting and run HEPA filter vacuum equipment throughout. This keeps foam dust out of living spaces and meets BPCA certification standards for containment.
Moisture mapping and documentation
Every job includes moisture meter readings, thermal imaging and photographs of cleared timbers. This documentation is what lenders and surveyors ask for when spray foam has held up a mortgage.
How open cell foam removal runs in Bath
Bath sits in a damp valley, and its housing stock ranges from Georgian townhouses to 1930s semis and post-war estates. That mix matters for open cell spray foam removal Bath jobs because ventilation behaves differently in each. Older stone properties in Widcombe and Bathwick often have limited eaves gaps, so foam sprayed tight to the felt causes condensation quickly. Newer homes in Twerton and Whiteway usually have more roof space but thinner rafters, so we cut more carefully. We work to PASMA and CITB safety standards, and we dispose of all foam through licensed waste routes. If you need remove open cell spray foam Bath services for a mortgage deadline, tell us at the survey and we will prioritise the clearance pack.
Service Areas
Many stone cottages here have shallow roof pitches and tight eaves, so foam often blocks the only ventilation path. We check airflow carefully before signing off.
Victorian terraces with converted lofts are common. Foam is often sprayed around dormer cheeks, so we use an oscillating multi-tool for precision cuts.
Post-war semis with trussed roofs and thinner rafters. We cut foam in smaller sections to avoid stressing the timber during extraction.
Elevated position and exposed roof decks mean more wind-driven rain. We test timber moisture thoroughly before and after removal.
Georgian properties with large roof spaces and original timbers. Dry ice blasting is often the best option to protect historic woodwork.
Local Considerations
Damp valley climate with high winter humidity
Open cell foam stays wet for longer, so trapped moisture and rot progress faster. We prioritise moisture testing and ventilation checks on every Bath job.
Older stone and brick housing stock
These walls need to breathe, and foam can trap moisture against the structure. We remove foam carefully and advise on breathable insulation options.
Listed and conservation-area properties
Extra care is needed around original timbers and roof structures. We use non-abrasive methods such as dry ice blasting where the fabric must be preserved.
Frequent mortgage and surveyor involvement
Bath has a high proportion of sales where surveyors flag spray foam. Our clearance documentation is designed around what lenders actually ask for.
Victorian terrace loft cleared for sale
A three-bedroom terrace in Oldfield Park had open cell foam sprayed across the entire loft, blocking eaves ventilation. The buyer's surveyor flagged it and the mortgage was declined. Timber moisture readings were 24% in two rafters.
We removed all foam in a day and a half, cleaned the rafters and treated the two damp timbers. Moisture readings dropped to 14% within a week, and the lender accepted our clearance pack. The sale completed without a price reduction.
Maintenance & Follow-up
Keep eaves vents clear and check the loft for condensation each winter. We recommend a moisture check every two years if the roof space is used for storage.
A bungalow in Combe Down had foam sprayed tight to the roof felt eight years ago. The loft smelled damp, ceiling plaster showed brown stains and stored boxes were soft with moisture. Thermal imaging showed cold spots across the whole roof deck.
We cut out the foam, restored the ventilation gap and cleaned the roof deck. Thermal imaging after the job showed even surface temperatures and no cold spots. The ceiling stains dried out and did not return.
Maintenance & Follow-up
Leave the loft hatch slightly open in winter to improve airflow, and avoid blocking eaves vents with stored items.
A landlord with two rental properties in Twerton had open cell foam in both lofts and damp complaints from tenants. One property had foam bridging the eaves and causing condensation on the cold water tank.
We cleared both lofts in five days, treated minor surface mould and provided clearance documentation for each address. Tenant complaints stopped, and both properties passed their next inspection without foam-related issues.
Maintenance & Follow-up
Book a loft inspection every 18 months and keep the tank area clear of stored items so airflow is not restricted.
How much does open cell spray foam removal cost in Bath?
Typical 2026 pricing in Bath runs from £1,800 to £4,500 for a standard loft, depending on foam depth, loft size and access. A small single-storey roof space may come in nearer £1,200, while a large detached property with foam across multiple roof sections can exceed £6,000. Every quote is fixed after a free survey.
Can you remove open cell spray foam in Bath, Somerset?
Yes. We remove open cell spray foam across Bath and the wider Somerset area, including Twerton, Widcombe, Combe Down and Oldfield Park. Open cell foam is soft and low-density, so it cuts out cleanly with a reciprocating saw and oscillating multi-tool. Most lofts are cleared in one to two days, with timber cleaning and inspection on the final day.

Does open cell spray foam removal damage plaster in Bath?
No, not when it is done properly. We work from the roof space side, cutting foam away from rafters without touching the ceiling plaster below. In the rare case where foam has pushed against a plasterboard ceiling, we use an oscillating multi-tool to cut it back carefully. Any minor plaster repair needed is flagged in your survey before work starts.

Reviews
Cleared open cell foam from our loft in Widcombe after a failed survey. Tidy, on time and the clearance pack was exactly what our lender wanted. Sale went through two weeks later.
We had foam in two rental properties in Twerton. Platinum Shield handled both in a week, treated the damp timbers and gave us proper documentation. No damp complaints since.
Used a thermal camera to show us where the moisture was, then removed the foam carefully around our plasterboard. Loft is dry and the price matched the quote.
Booked a same-day survey for a mortgage deadline. Foam out in a day and a half, photos and moisture readings provided. Professional from start to finish.
