Spray Foam Insulation Problems | FAQs for Homeowners
Get straight answers to the most common questions UK homeowners have about spray foam insulation problems, removals, mortgages and surveys.
Will spray foam affect my house sale?
It can. Many buyers’ solicitors and surveyors will flag spray foam during the conveyancing process. Some buyers’ lenders will refuse to lend on the property, which can cause the sale to collapse. Acting quickly and getting the right advice early gives you the best chance of saving the sale.
Is spray foam removal covered by insurance?
In most cases, no. Spray foam removal is generally not covered by standard home insurance policies. Some homeowners have successfully pursued claims against companies that mis-sold spray foam insulation, but this is complex and not guaranteed.
How do I know if I have open-cell or closed-cell spray foam?
Open-cell foam is soft, spongy and yellowish or white in colour. Closed-cell foam is rigid, dense and typically cream or yellow. A specialist can confirm the type during an assessment. The type of foam affects both the removal approach and the cost.
Can I sell my house with spray foam insulation?
You can market a property with spray foam, but you must disclose it. Depending on the buyer’s lender, the sale may fall through at the mortgage application stage. Getting the foam removed before marketing — with the right documentation — puts you in a much stronger position.
My surveyor said spray foam has voided my roof warranty — what does this mean?
Many roofing products carry manufacturer warranties that are voided if spray foam is applied over them. This does not necessarily mean the roof is structurally damaged, but it is a concern lenders and insurers take seriously. An independent assessment will clarify the position.
