Spray Foam & Mortgage Problems: What You Need to Know
If your property has spray foam insulation in the loft or roof space, you may have already been told by a mortgage lender or surveyor that they cannot proceed. This is one of the most common reasons homeowners in Cornwall contact us.
Spray foam prevents lenders and surveyors from inspecting the condition of the timber roof structure underneath. As a result:
- Most high street mortgage lenders will decline or withdraw applications on properties with spray foam
- Surveyors routinely flag spray foam as a risk, causing sales to fall through
- Remortgaging — including equity release — is often blocked until the foam is removed
- Home insurance can be affected too, as the presence of foam makes structural surveys difficult
The good news: removing the spray foam professionally resolves these issues in the vast majority of cases. Our team has helped homeowners across Cornwall get their sales back on track and mortgage applications approved.
Why Spray Foam Insulation Needs to Be Removed
Beyond mortgage issues, spray foam causes serious long-term problems for your property:
Moisture Damage & Timber Rot
Spray foam traps moisture against timber roof structures. We regularly find moisture readings of 25–30% in affected roof spaces — healthy timber should be between 9–15%. This leads to rot, structural weakening, and costly repairs if left untreated.
Loss of Breathability
Traditional Cornish homes — particularly older and heritage properties — need to breathe. Spray foam seals the roof space, preventing moisture from escaping and leading to interstitial condensation and mould.
