What's included
What Our Cavity Foam Removal Includes
Every cavity wall spray foam removal Taunton job includes survey, extraction, verification and making good as standard. Reinstating the cavity with a compliant insulation system is quoted separately, because not every customer wants it and some lenders prefer the cavity left empty and vented.
Full Cavity Survey
Thermal imaging and moisture readings across every elevation, with a written report on foam location, wall condition and any damp found. You get this before you commit to anything, and it forms the basis of the fixed price.
Complete Foam Extraction
Removal of injected polyurethane foam from the cavity using dry ice blasting, mechanical tooling and industrial vacuum extraction. We clear the full wall, not just the easy sections near the access holes.
Cavity Verification
Borescope and thermal camera checks after extraction to confirm the cavity is clear and air can move. You receive dated photographs of the empty cavity, which is the evidence lenders and surveyors want to see.
Making Good and Repointing
Access holes repointed with matching mortar and any disturbed plasterboard refitted. The elevation is left weathertight and, in most cases, you cannot tell where we worked once the mortar has cured.
Completion Documentation
A written completion statement, extraction record and photographic pack issued after the job. This is the paperwork your solicitor, broker or buyer's surveyor will ask for during a sale.
Waste Removal and Disposal
All foam, dust and debris bagged and removed from site, then disposed of through licensed waste routes. You are not left with skips on the drive or bags of foam to get rid of yourself.
Service overview
Cavity Wall Spray Foam Removal in Taunton Explained
Cavity Wall Spray Foam Removal in Taunton is the controlled extraction of injected polyurethane foam from the gap between your inner and outer brickwork. Foam pumped into a cavity in the 1990s or 2000s can shrink, crack and trap moisture against the inner leaf. We cut access points at mortar joints, break the foam down with dry ice blasting or mechanical extraction, pull it out with an industrial vacuum extractor, and confirm the cavity is clear with a thermal imaging camera before we make good.
Taunton's older terraces and 1930s semis around North Town and Rowbarton were built with narrow 50mm cavities that were never designed for injected foam. Add Somerset's driving rain off the Quantocks and you get damp and condensation from trapped moisture, cold bridging, and mortgage lender refusal due to spray foam. If you have searched cavity wall spray foam removal Taunton near me because a surveyor has flagged the wall, we can survey, extract and document the job in one visit.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
How Our Removal Process Works
The process flexes to the condition, but these checkpoints keep decisions clear.
Survey and Assessment
We start with an Insulation Assessment using a thermal imaging camera and moisture meter to map where the foam sits and how wet the wall is. You get a fixed price the same day, not a range that moves once work starts. Surveys across Taunton usually take 45 to 60 minutes.
Access and Containment
On the day, we sheet floors, seal doors and set up a dust extraction unit and air scrubber so the house stays liveable. Access holes are cut at mortar joints, typically 20mm to 25mm, spaced roughly every metre along the wall. Bricks are set aside and reused when we make good.
Foam Extraction
We break the foam down with a dry ice blasting machine or mechanical tooling, then pull it out with an industrial vacuum extractor. A reciprocating saw and oscillating multi-tool handle stubborn sections bonded to ties. A typical three-bed semi takes one to two days.
Verification and Documentation
Every cavity is checked with a thermal imaging camera and borescope before we close anything up. You receive dated photographs, a written completion statement and the extraction record. That pack is what lenders, surveyors and solicitors ask for when the foam question comes up.
Making Good and Reinstatement
We repoint the access holes with matching mortar, refit any disturbed plasterboard, and leave the wall weathertight. If you want the cavity refilled properly, we can specify mineral wool or a vapour barrier system that meets PAS 2035 rather than pumping foam back in.
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 fractures foam so it releases from brickwork without gouging the brick face. Our preferred method on fragile Victorian walls around Taunton Town Centre.
Industrial vacuum extractor
Pulls loosened foam and dust out of the cavity through the access holes. HEPA filtration keeps fine particles out of the living space.
Thermal imaging camera
Maps foam location and cold bridging before work starts, then verifies the cavity is clear afterwards. The before-and-after images go into your documentation pack.
Moisture meter
Reads the water content of the inner leaf so we know how wet the wall is and whether it needs to dry before reinstatement.
Dust extraction unit and air scrubber
Run continuously during extraction to keep dust out of the house. Combined with zip barriers and a PPE respirator, this is why most customers stay in during the work.
Reciprocating saw and oscillating multi-tool
Cut through foam bonded hard to wall ties and lintels where blasting alone will not shift it. Used carefully to avoid damaging the tie.
Borescope
Inspection camera fed into the cavity to confirm the foam is fully removed and check the condition of ties and the inner leaf.
Use cases
When to Book Cavity Foam Removal
These examples show how the service framework adapts rather than forcing every call through one repair.
Damp Gable End Dried Out in Galmington
A landlord's rental in Galmington had tide marks up the gable wall and a musty smell in the back bedroom. The foam had shrunk away from the brickwork and was holding water against the inner leaf. Two previous attempts to treat it as a render problem had failed. → We extracted the foam from the gable cavity in a single day, checked the inner leaf with a moisture meter, and left the wall to dry. Readings dropped from 22 percent to under 12 percent over eight weeks. The tenant stayed in the property throughout and the damp smell cleared.
Pre-Move Foam Clearance in Bishops Hull
Buyers in Bishops Hull had exchanged on a 1970s house with foam in two cavity walls. They wanted it gone before moving in and had a three-week void between exchange and completion. The foam was dense closed cell and bonded hard to the inner leaf. → We scheduled the extraction for the void period, broke down the closed cell foam with mechanical tooling, and vacuum extracted it from both elevations in two days. The cavity was verified clear, access holes were repointed, and the documentation was emailed the same week. They moved into a property with no outstanding survey objections.
Problems we solve
Problems We Solve for Taunton Homeowners
Cavity foam causes a small number of very specific problems, and they all get worse the longer they are left. Here is what we see most often across Taunton and what it takes to put it right.
Mortgage lender refuses to lend on a foam-filled cavity
We extract the foam and issue dated photographs and a completion statement showing the cavity is clear. Your broker sends that to the underwriter, and in most cases the lender proceeds without a second survey.
Damp and condensation from trapped moisture
We remove the foam so air can move through the cavity again, then check the inner leaf with a moisture meter. The wall dries out over six to ten weeks, and we tell you what to watch for in that period.
Reduced property value and difficulty selling
Clearing the foam removes the objection. We provide the documentation pack that answers the surveyor's question before it is asked, so your asking price stands on the building rather than on a problem.
Building regulation non-compliance on retrofit work
We remove the non-compliant foam and, if you want the cavity refilled, specify a mineral wool or vapour barrier system that meets PAS 2035. The reinstatement specification is issued in writing with the completion pack.
Pricing process
What Cavity Foam Removal Costs
900 - 3,200 pounds depending on wall length, foam density and number of elevations
Number of elevations
Foam is often only in the walls that faced the weather when it was installed. One elevation starts around 900 pounds; all four on a semi can reach 3,200 pounds. We survey every wall so you only pay for foam that is actually there.
Foam density and type
Open cell foam breaks down quickly with dry ice blasting. Closed cell foam cures hard against the brickwork and needs mechanical breaking first, which adds roughly half a day and a few hundred pounds to a typical Taunton job.
Cavity width and access
Narrow 50mm cavities in older terraces slow the work down because there is less room for tooling. Wide cavities on post-war estates are quicker to clear, which brings the price down.
How much does cavity wall spray foam removal cost in Taunton?
Typical 2026 pricing in Taunton runs from 900 pounds for a single elevation to around 3,200 pounds for a full three-bed semi with foam on all four walls. Wall length, foam density and access all move the number. You get a fixed written price after the survey, and that figure does not change once work begins.
Who does cavity wall foam insulation removal in Taunton Somerset?
British Spray Foam Co does, and we have been doing it across Somerset since 2021. We hold City & Guilds insulation qualifications, are CHAS accredited and TrustMark registered, and we issue the completion documentation lenders ask for. Call 0182 329 7064 and we will book a survey, usually within a few days.
Can cavity wall spray foam removal be done same day in Taunton?
Yes for single elevations and small areas, which we can often clear in one working day. A full semi with foam on every wall takes two to three days. We confirm the schedule at survey so you can plan around it, and we keep water and power on throughout wherever possible.
Is cavity wall foam removal covered by insurance in Taunton?
Sometimes. If the foam was installed by a registered installer under a guarantee, or if it is causing damage a policy covers, your insurer may contribute. Most Taunton customers pay directly and treat it as a cost of sale. We provide itemised invoices and photographs that support any claim you make.
