After TSB declined his remortgage, Richard's NFSA survey identified the removal scope required. His lender accepted the report — application approved the following week.

No removal needed
Avoided unnecessary £7k removal
Sarah had been quoted £7,000 to remove her loft foam. Our independent surveyor found it was a compliant closed-cell install with no moisture issues. No removal required.
Sarah, York · February 2026
Hidden damage found
Found the damp before it spread
A pre-sale survey at Ahmed's home uncovered trapped moisture and early timber decay behind an otherwise tidy-looking foam install. Remediation costs a fraction of what a structural failure would have.

Frequently Asked Questions
Quick answers to common questions about spray foam removal and our service
Why do mortgage lenders reject properties with spray foam insulation?
Mortgage lenders reject spray foam because it can trap moisture in roof timbers, leading to rot and structural damage. Many lenders now have blanket policies refusing to lend on properties with spray foam until it's professionally removed and the roof structure is certified as sound.
How much does spray foam removal cost?
Through our partner network, spray foam removal starts from just £52/m² for open cell foam and £70/m² for closed cell. This includes everything: loft access, floor protection, cleaning, lender-compliant certificate of removal, and damage report - all as standard. Most 3-bed properties cost £2,000-£4,000 total. Use our instant quote tool to get an accurate estimate.
Is your service really free?
Yes, absolutely. We don't charge homeowners for advice, specialist connections, or quote requests. There are no hidden fees or obligations. We're funded by our network of specialists who pay us for quality leads, not by homeowners.
How quickly can I get removal quotes?
Most homeowners receive contact from vetted specialists within 24-48 hours of submitting a quote request. We connect you with up to 3 local specialists who will assess your property and provide detailed, no-obligation quotes.
Will removal restore my property value?
Yes. Properties with spray foam can be devalued by 30-50% or become unmortgageable. Professional removal with proper certification typically restores full market value, making the investment worthwhile. With removal costs starting from around £2,000 for smaller properties, you're often saving tens of thousands in property value.
What happens if the survey says I don't need removal?
Then we'll tell you. NFSA is an association, not a removal company — we're not paid to recommend work that isn't needed. If your foam install is compliant and the roof is sound, your report will say so, and you'll have documented evidence for your lender, buyer, or insurer. Roughly one in six surveys we commission returns a “no action needed” outcome.
What areas do you cover?
Our specialist network covers all regions of the UK including England, Scotland, Wales, and Northern Ireland. Wherever you're located, we can connect you with local, vetted professionals who understand regional requirements and building regulations.
Not sure whether your foam needs removing?
Request a free independent survey from the NFSA advisory panel. No obligation, no pressure, no hidden fees — and if you don't need removal, your report will say so.
