Cavity Wall Spray Foam Removal in Weston super Mare clears failed polyurethane foam from wall cavities so your brickwork can breathe again. We handle mortgage lender spray foam removal, cavity wall spray foam extraction Weston super Mare and full make-good across Somerset. If a surveyor has flagged foam in your walls, or damp and condensation are creeping in, we cut it out, clean the cavity and leave you with a report your lender accepts.
Cavity Wall Spray Foam Removal in Weston super Mare is the controlled extraction of injected polyurethane foam from the cavity between your inner and outer walls. Foam was pumped into thousands of homes across Somerset as cheap insulation, and much of it has since failed. We cut access points through the outer leaf, break the foam down with a spray foam removal saw and oscillating multi-tool, then pull it out with an industrial vacuum. The cavity is then cleaned, inspected with a thermal imaging camera and left ready for a breathable insulation system.
Weston super Mare's position on the Bristol Channel means driving rain and salt-laden air hit exposed elevations hard. Foam that bridged the cavity traps that moisture against the inner leaf, and we see the results constantly: blown plaster, damp patches at skirting level, timber rot from trapped moisture and cold bridging that makes rooms feel colder than they should. If a mortgage refusal due to spray foam has landed on your desk, or you are struggling with difficulty selling property, cavity wall foam removal Weston super Mare is the fix. We cover the whole town and surrounding villages.
Every cavity extraction we carry out in Weston super Mare includes the full sequence below as standard. There is no separate charge for the survey, the report or the make-good. If scaffolding is needed for high elevations, we confirm that in the fixed quote before we start.
Inspection holes at agreed points, thermal imaging camera mapping and a written assessment of foam type, coverage and any damp or timber rot found. You get a fixed price the same day, usually within two hours of the visit.
Access holes drilled at 1m centres, foam cut out with a spray foam removal saw and oscillating multi-tool, and full removal with an industrial vacuum. Dust is contained at source and extracted to the outside throughout.
Residual foam cleaned from cavity faces, wall ties checked and photographed, and airflow confirmed with a thermal imaging camera. Any damaged mortar or ties are noted in the final report with recommended repairs.
Access holes filled, pointed and colour-matched to the surrounding brickwork. On rendered walls we patch and texture to match. You are left with a wall that looks no different from before we arrived.
A written report with before-and-after photographs, cavity condition notes, thermal imaging evidence and a workmanship warranty. This is the document lenders, valuers and buyers ask for, and it is included in the price.
All extracted foam is bagged, labelled and removed from site the same day, disposed of through licensed waste routes. Nothing is left in your garden, driveway or skip for you to deal with.
We attend, drill small inspection holes at agreed points and use a thermal imaging camera to map where foam sits and how far it has spread. You get a fixed written price the same day, usually within two hours of the visit. No charge for the survey, no obligation.
We sheet floors, seal doorways and set up extraction hose runs to the outside. Respirators and protective clothing go on before any cutting starts. On a typical semi-detached house, setup takes 45 to 60 minutes and the dust extraction is running before the first access hole is opened.
Foam comes out through 100mm access holes drilled at 1m centres along the wall. We break the bond with a spray foam removal saw and oscillating multi-tool, then pull the material out with an industrial vacuum. A three-bed semi usually takes two to three days for full cavity extraction.
Once the bulk is out, we clean residual foam from the cavity faces, check for timber rot from trapped moisture and photograph every section. A thermal imaging camera confirms the cavity is clear and airflow has returned. Any damaged wall ties or mortar are noted in the report.
Access holes are filled, pointed and colour-matched to the existing brickwork. We hand over an extraction report with before-and-after photographs, cavity condition notes and a workmanship warranty. That document is what your lender, valuer or buyer actually needs to see.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Cuts through dense closed cell foam and breaks the bond to the cavity face without gouging the brickwork. Used alongside an oscillating multi-tool for edges and corners.
Pulls loose foam, dust and debris out of the cavity and extracts it to the outside. Keeps the working area clean and stops foam dust migrating into living space.
Maps foam coverage during the survey and confirms the cavity is clear and ventilating at final inspection. The images also go into your extraction report as evidence for lenders.
Removes foam residue from delicate substrates and hard-to-reach areas without abrasive damage. Used where a saw or sand blasting equipment would be too aggressive for the surface.
Strips stubborn foam residue from brick and block faces after the bulk has been cut out. Fully contained, followed by a clean-down and inspection.
Polyurethane foam dust is not something to breathe. Every technician wears a fitted respirator, coveralls, gloves and eye protection for the duration of the extraction.
A three-bed semi in Worle had injected closed cell foam throughout the front and rear cavities. The buyer's lender refused the mortgage and the sale stalled for six weeks while the owner tried to find a removal contractor who could provide acceptable paperwork.
We surveyed on the Tuesday, quoted the same day and completed extraction in three working days. The report went to the lender the day we finished. The valuer signed off within a week and the sale completed four weeks later.
A detached house in Uphill had damp patches at skirting level on the sea-facing wall for two consecutive winters. The owner had re-plastered twice with no lasting result. Thermal imaging showed foam bridging the cavity and holding water against the inner leaf.
We extracted the foam from the affected elevation, cleaned the cavity and restored the airflow path. Damp readings fell from 28% to under 12% within eight weeks. The plaster has stayed dry through a full winter since.
A 1950s semi in Bournville had cavity foam plus loft foam at eaves level. The roof space was dripping with condensation, mould was spreading across the sarking and the owner was worried about timber rot. Two roofers had told him the roof needed replacing.
We removed both the cavity and loft foam, reinstated the eaves ventilation gap and confirmed airflow with a thermal imaging camera. The roof space dried out over the following months. No roof replacement was needed.
Cavity foam problems rarely stay in the cavity. They show up in mortgage valuations, damp readings, heating bills and eventually in the structure of the building. Here is what we deal with most often across Weston super Mare.

We remove cavity and loft foam together, reinstate the eaves ventilation gap and confirm airflow with a thermal imaging camera. Where timbers have already suffered, we note the extent in the report so you can get a carpenter in before it gets worse.

Most Weston super Mare cavity wall spray foam removal jobs run between £1,800 and £4,500 in 2026, depending on wall area, foam type and access. A typical three-bed semi sits around £2,400 to £3,200. Closed cell spray foam costs more to remove than open cell because it is denser and bonds harder to the brickwork. We give you a fixed price after the survey, so there are no day-rate surprises.
