If a spray foam survey has stalled your sale or remortgage, you are not alone. Thousands of homeowners across Surrey had insulation sprayed into their lofts during the green-grant years, and are now finding that lenders and RICS surveyors treat it as a problem rather than an improvement. The good news is that it is a fixable one.
We help homeowners in Farnham, Aldershot, Godalming and the surrounding villages remove spray foam properly and get the written evidence a lender needs to proceed. We are not a national franchise reading from a script — enquiries go to a selected local contractor who surveys your loft, gives you a fixed price, and does the work.
Why spray foam becomes a problem
Spray foam was sold as an energy-saving upgrade, and for a while it was grant-funded heavily. The difficulty is not always the foam itself — it is that once it is sprayed onto the underside of the roof, a surveyor can no longer see the felt and timbers underneath. Closed-cell foam in particular is rigid and can trap moisture against the rafters, and because the timbers are hidden, most lenders now assume the worst and decline to lend.
That leaves owners stuck: the sale falls through, the remortgage is refused, and even some insurers become hesitant. Removing the foam and obtaining an independent report is what unlocks the situation.
What proper removal involves
Removal is more than scraping foam off a rafter. Closed-cell foam is bonded hard to the surface and has to be taken back carefully so the timbers are not damaged, the roof stays watertight, and the waste — which is not ordinary household rubbish — is removed responsibly. Once it is clear, the timbers can be inspected, treated if needed, and signed off in a report.

Frequently asked questions
How much does spray foam removal cost in Farnham?
Most Farnham loft removals fall between £2,000 and £6,000. Closed-cell foam bonded to the felt or timber costs more than softer open-cell foam, and the size of the roof, ease of access and how the waste is handled all affect the final figure. You should always get a fixed quote after a survey rather than a phone estimate.
Why do mortgage lenders refuse homes with spray foam?
Since 2023 most UK lenders have tightened their stance because foam sprayed onto the underside of the roof can hide rot, trap moisture and stop a surveyor inspecting the timbers. Many will not lend until the foam is removed and a satisfactory report is provided, which is exactly the situation we help homeowners resolve.
Do I definitely need to remove spray foam?
Not always. If a qualified surveyor can confirm the installation was done correctly and the timbers are sound, some lenders will accept it. But in practice, for older Farnham properties with closed-cell foam, removal followed by an independent report is usually the quickest route to a sale or remortgage.
How long does removal take?
A typical semi or detached loft is cleared in one to three days depending on the type of foam and roof size. Access, waste removal and any timber treatment can add time, which the surveying contractor will confirm before starting.
