What's included
What our cavity wall spray foam removal includes
Every cavity wall spray foam removal in Ashby de la Zouch is quoted as a complete job. The survey, the extraction, the clean-up and the report are all in the price. The only thing we quote separately is replacement insulation, because that depends on what you choose to fit afterwards.
Free cavity survey
We inspect the cavity with a borescope and thermal imaging camera, identify whether the foam is open cell or closed cell, and measure the cavity run. You get a fixed written price the same day, with no charge and no obligation to book.
Full foam extraction
All accessible foam is cut free and vacuumed out through sealed hoses. We work along the cavity in sections, re-opening the original injection holes rather than cutting new ones, and we check progress with the thermal imaging camera as we go.
Dust and chemical controls
Doorways are sealed, floors covered with protective sheeting, and air scrubbers run throughout. Technicians wear respirators and protective clothing, and all waste goes into sealed waste disposal bags for documented disposal.
Cavity clean and inspection
We sweep the cavity, clear residue from around wall ties, and photograph the finished result. If stubborn patches remain, we treat them with the dry ice blasting machine before signing the job off. Nothing is left for you to clear.
Written extraction report
You get dated photographs, cavity moisture readings, thermal imaging camera images and waste transfer notes in one pack. This is the document lenders, solicitors and surveyors ask for, and we provide extra detail free if your lender requests it.
Five-year workmanship warranty
The extraction itself is covered by a 5-year workmanship warranty. If foam residue or a blocked air gap causes an issue within that period, we return and put it right. Replacement insulation carries its own manufacturer warranty.
Service overview
Cavity wall spray foam removal in Ashby de la Zouch
Cavity wall spray foam removal in Ashby de la Zouch is the controlled extraction of polyurethane foam that has been injected between the inner and outer leaves of a brick or stone wall. We drill small access points at each injection hole, break the foam down with a spray foam removal saw and oscillating multi-tool, then pull the material out with an industrial vacuum. Open cell foam comes away fairly quickly; closed cell foam is denser and needs more passes, but both can be cleared without removing the outer brickwork.
Most people in Ashby de la Zouch ring us after a mortgage lender refuses to lend on a property with spray foam in the cavity, or after a surveyor flags loft condensation and roof timber rot caused by trapped moisture. Cavity wall foam extraction Ashby de la Zouch jobs are usually booked before a sale completes, so timing matters. We also handle cavity wall insulation removal Ashby de la Zouch Leicestershire homeowners need when old foam has started to crumble and block the air gap entirely.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
How our extraction process works
The process flexes to the condition, but these checkpoints keep decisions clear.
Survey and quote
We attend, inspect the cavity with a thermal imaging camera and a borescope, and confirm whether the foam is open cell or closed cell. You get a fixed written price the same day, usually within two hours of the visit. There is no charge for the survey across Ashby de la Zouch and the surrounding villages.
Protect the property
Furniture is moved clear, floors are covered with protective sheeting, and we seal doorways with zip barriers. An air scrubber runs throughout to keep dust out of living space. On a typical three-bed semi this setup takes around 45 minutes before any cutting starts.
Extract the foam
We re-open the original injection holes and work along the cavity in sections. The spray foam removal saw and oscillating multi-tool break the bond, then the industrial vacuum pulls material out through a sealed hose. A three-bed semi usually takes one to two days; larger detached homes run to three.
Clear and inspect
Every cavity is swept, checked with the thermal imaging camera and photographed. We confirm the air gap is fully open and that no foam fragments remain around wall ties. If any stubborn patches need dry ice blasting machine treatment, we do that before we pack up.
Report and handover
You receive a written extraction report with photographs, cavity readings and waste transfer notes. This is the pack lenders, solicitors and surveyors ask for. We also give you a clear recommendation on replacement insulation and a 5-year workmanship warranty on the extraction itself.
Tools & methods
Tools and methods we use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Spray foam removal saw
Cuts through cured closed cell foam and breaks the bond along the cavity without damaging the brick faces. It is the main cutting tool on denser foams.
Oscillating multi-tool
Gets into corners, around wall ties and behind lintels where the saw cannot reach. Essential for a clean cavity with no leftover fragments.
Industrial vacuum
Pulls foam debris and dust out through a sealed hose. Keeps the work zone contained and stops dust migrating into living space.
Thermal imaging camera
Maps cold spots and moisture patterns before and after extraction. The images go into your report as evidence for lenders and solicitors.
Dry ice blasting machine
Uses dry ice pellets to freeze and shatter stubborn foam residue on wall ties and engineering brick. Leaves a genuinely clean surface.
Air scrubber
Runs continuously during cutting to filter airborne dust. Standard kit on every internal job, particularly where the loft hatch opens into a landing.
Respirators and protective clothing
Required under COSHH for foam dust and isocyanate residue. Every technician wears full protection for the duration of the cutting work.
Use cases
When to book cavity wall spray foam removal
These examples show how the service framework adapts rather than forcing every call through one repair.
Detached property, Packington
Foam had been injected into both the cavity and the loft during a 2010 retrofit. The owner was getting condensation on the landing ceiling and had noticed dark staining on two rafters. Two other firms had quoted for the cavity only and refused the loft. → We cleared the cavity and the loft in a single three-day booking, running air scrubbers throughout. Early rot on two rafters was caught and repaired by a joiner for a few hundred pounds rather than a full roof section. Ventilation was restored at the eaves.
Rental terrace, Moira
A landlord was dealing with recurring mould complaints from a tenant. The cavity was full of crumbling open cell foam that had started to block the air gap, and the bathroom extractor was venting into the loft rather than outside. → The cavity was cleared in a single day and the extractor duct was rerouted through the roof. Moisture readings on the affected wall fell from 18 percent to 11 percent over six weeks. The tenant reported no further mould growth through the following winter.
Problems we solve
Problems cavity wall foam extraction in Ashby de la Zouch solves
Spray foam in a cavity rarely causes one problem on its own. It traps moisture, blocks ventilation and puts a hold on your mortgage. Here are the issues we deal with most often in Ashby de la Zouch and how we clear them.
Spray foam causing mortgage refusal
We extract the foam, document the cleared cavity with photographs and thermal imaging camera readings, and issue a report in the format lenders accept. Most Ashby de la Zouch sales we unblock complete within four to six weeks of extraction.
Loft condensation and damp patches
Extraction restores the air gap so the wall can dry out. We take moisture readings before and after, and where the loft is also affected we clear that foam in the same visit. Most walls drop back to normal readings within four to six weeks.
Roof timber rot from trapped moisture
We remove the foam, inspect the timbers and flag any rot for a joiner. Clearing the ventilation path stops the rot spreading. On Ashby de la Zouch jobs we have caught early rot that needed a two-rafter repair rather than a full roof section.
Difficult removal due to adhesion
We use the spray foam removal saw, oscillating multi-tool and dry ice blasting machine to break the bond without damaging brickwork. Wall ties are cleaned individually, and the cavity is checked with a thermal imaging camera before we sign off.
Pricing process
What cavity wall spray foam removal costs
1,800 - 4,500 pounds depending on property size, foam type and access
Cavity length and elevation count
A semi with two elevations costs less than a detached property with four. We measure the actual cavity run during the survey rather than estimating from floor area, which is why our quotes hold up.
Open cell or closed cell foam
Closed cell foam is denser and bonds harder to brick, so it takes longer to cut and vacuum. Expect closed cell work to run 30 to 40 percent higher than open cell on the same property.
Access and scaffolding
Most cavity work is done from ground level or a small tower. If a wall is only reachable from a neighbouring garden or over a conservatory, access costs are added to the quote upfront rather than as a surprise.
How much does cavity wall spray foam removal cost in Ashby de la Zouch?
Most Ashby de la Zouch cavity wall spray foam removal jobs run between 1,800 and 3,200 pounds for a three-bed semi in 2026. Detached homes with long cavity runs can reach 4,500 pounds. The price depends on cavity length, whether the foam is open cell or closed cell, and how accessible the walls are. The survey and written quote are free.

Yes. We extract both open cell and closed cell spray foam from cavity walls across Ashby de la Zouch and the whole of Leicestershire.

A three-bed semi takes one to two days, and you get a written report for your lender or solicitor at the end.
