Open Cell Spray Foam
Removal Specialists
Open-cell spray foam is the most common cause of mortgage refusals in the UK. Our certified extraction process removes every trace and restores full lender compliance within days.
Why Open-Cell Foam Is the #1 Mortgage Killer
Open-cell polyurethane spray foam was widely marketed as an energy-saving insulation solution throughout the 2000s and 2010s. The reality for homeowners has been very different.
Open-cell spray foam insulation was applied to hundreds of thousands of UK roofs — often incentivised through energy efficiency schemes. It was promoted as a cost-effective way to reduce heat loss and improve EPC ratings.
However, RICS surveyors and mortgage lenders quickly identified a critical problem: the foam's moisture-absorbing properties create perfect conditions for accelerated timber decay, making it impossible to inspect the structural condition of the roof.
Today, open-cell spray foam is explicitly flagged as a non-acceptable property condition by Halifax, Nationwide, Barclays, NatWest, HSBC, Santander, and virtually every other UK mortgage lender. If you have open-cell foam, removal is the only path to mortgage eligibility.

The Four Critical Risks of Open-Cell Foam
Left untreated, open-cell spray foam creates compounding risks that affect your property value, structural integrity, and mortgage eligibility simultaneously.
Moisture Absorption
Open-cell foam readily absorbs and retains moisture from the surrounding environment, creating ideal conditions for timber decay and mould growth within your roof structure.
Timber Decay Acceleration
Trapped moisture between the foam and roof timbers accelerates wood rot by 3–5x compared to uninsulated lofts. Many cases show significant decay within 5–8 years of installation.
Structural Weakening
Progressive timber decay compromises the structural integrity of your roof over time, leading to costly repairs beyond just foam removal.
Lender Non-Compliance
Open-cell spray foam is the most commonly flagged foam type by RICS surveyors and mortgage lenders. All major UK lenders now refuse to lend against properties with open-cell spray foam.
Precision Open-Cell Removal Process
Every open-cell foam removal follows our proven 6-stage methodology — engineered to satisfy RICS surveyors and all major UK mortgage lenders.
HEPA Vacuum Extraction
Industrial-grade HEPA-filtered vacuum systems remove the bulk of open-cell foam without disturbing roof timbers or generating excessive particulate.
Rotary Cleaning
Specialist rotary brushes remove residual foam material embedded in timber grain and rough surfaces, ensuring complete extraction down to bare wood.
Moisture Assessment
Calibrated moisture meters test every timber member for elevated moisture content before and after removal, documenting conditions throughout.
Timber Inspection
Each rafter, joist, and purlin is individually inspected for signs of decay, softness, or structural compromise. All findings documented photographically.
Fungicide Treatment
Professional boron-based fungicide applied to all treated surfaces, eliminating existing fungal spores and providing long-term protection against future decay.
Certification
EBR-01 compliant certificate issued with full photographic evidence, moisture readings, and 10-year insurance-backed guarantee.
