Quick summary: Spray foam affecting your mortgage, remortgage, equity release or house sale? Understand the problem, what evidence may help and your complaint options.
Start with the installation record
Gather the quote, contract, invoice, guarantee, product name, installer details, photographs, any grant paperwork and any survey or ventilation information provided at the time. If a salesperson made promises about mortgage approval, energy savings or resale value, keep the wording that shows it.
Separate survey evidence from sales evidence
Mortgage problems often involve two different questions: whether the roof condition now concerns a lender, and whether the original sale or installation was explained properly. Keep the lender refusal, valuation notes and survey comments separate from the original sales material.
Build a dated timeline
A useful timeline shows the installation date, any follow-up inspections, when you tried to sell or remortgage, what the surveyor said, what the lender decided and what response you received from the installer or finance provider.
Avoid overclaiming the position
Spray foam does not always mean the same thing in every property. The issue is easier to review when the complaint explains the actual impact on your home, mortgage application, sale, valuation or removal decision.
Photo evidence can help explain the problem
Photos should not replace survey or lender documents, but they can help show what was installed and why inspection, ventilation or removal concerns were raised.
Evidence checklist
- Installation quote, contract and invoice
- Product details, guarantee and installer documents
- Before and after photographs if available
- Surveyor comments, valuation notes or lender refusal
- Messages showing what was promised before installation
- Any finance, grant or payment records linked to the work
Watch: Spray foam concerns covered in the media
Media coverage has highlighted why spray foam can create mortgage, survey and removal concerns for some homeowners. This video is included as general background only. Your own position depends on your property, documents, lender response, survey evidence and installation records.
Common questions
What if I do not have all the installer documents?
Start with what you do have: invoice, bank statement, photographs, emails, texts and any label or paperwork in the loft. Missing paperwork can itself be relevant if clear information was not provided.
Should I remove the spray foam before complaining?
Do not rush into removal just for paperwork reasons. Keep evidence of the current condition, survey comments and any professional advice before making a costly decision.
Can a lender refusal help my evidence?
Yes. A lender refusal, valuation note or survey comment can help show the practical impact, but it should be matched with installation and sales documents where possible.
Should I keep removal quotes even if I have not removed the foam?
Yes. Removal quotes can help show the practical cost and impact, but they should be kept separate from survey comments and lender decisions.
What if the installer said the product was mortgage safe?
Keep any brochure, quote, email, message or note showing that promise. It may be important when comparing the sales explanation with the later mortgage or survey problem.
