Spray Foam Mortgage Crisis
Expert Resolution Letters for Trapped Moisture, Mold, and Unmortgageable Homes
⚠️ Is Your Spray Foam Making Your Home Unmortgageable?
We specialize in resolution letters that address lender requirements and hold contractors accountable for moisture traps and mold growth.
The Spray Foam Crisis Explained
Spray foam insulation was marketed as an energy-saving solution, but thousands of UK homeowners are now discovering it's making their homes unmortgageable. The problem isn't the foam itself—it's how it was installed and the devastating consequences for your property value.
The Three Critical Problems
1. Trapped Moisture
Spray foam creates an airtight seal that traps moisture in your roof space. Without proper ventilation, this moisture has nowhere to go, leading to condensation and structural damage.
2. Mold Growth
Trapped moisture creates the perfect environment for mold and rot. This isn't just unsightly—it's a serious health hazard that can cause respiratory problems and allergic reactions.
3. Mortgage Refusal
Lenders are now refusing mortgages on properties with spray foam insulation. This means you can't sell, can't remortgage, and your property value has plummeted.

Real Consequences for Real People
This isn't just about insulation—it's about your home, your health, and your financial future:

- Unable to Remortgage: You're stuck with your current lender, often at higher rates
- Property Devaluation: Your home is worth significantly less, or worthless, with spray foam
- Removal Costs: Professional removal can cost £10,000-£30,000+
- Health Impacts: Mold exposure can cause serious respiratory problems
- Structural Damage: Trapped moisture can rot timber and damage your roof structure
You're Not Alone—And It's Not Your Fault
Thousands of UK homeowners are in the same situation. The contractors who installed spray foam didn't warn you about these risks. They didn't ensure proper ventilation. They didn't tell you it would make your home unmortgageable.
That's why they're accountable.

Spray Foam Insulation — FAQs
Why does spray foam make a home hard to mortgage?
Most high-street lenders and building societies will not lend against a property where spray foam has been applied to the roof rafters or underside of the roof deck. Their concern is twofold: the foam can conceal the condition of the underlying timber (making a surveyor's assessment unreliable), and it can trap moisture against the wood, accelerating rot and structural deterioration. Until an independent structural survey confirms the timber is sound — or the foam is professionally removed — many lenders simply decline the application. This can prevent you from selling, remortgaging, or releasing equity.
Can I claim if spray foam was mis-sold to me?
Potentially, yes. If the installer or salesperson made representations that were inaccurate or misleading — for example, that the foam would have no impact on your property's saleability, that it was a fully approved insulation method, or that it would deliver specific energy savings — you may have grounds for a mis-selling complaint. Similarly, if the installation caused measurable harm such as moisture damage, structural deterioration, or a reduction in your property's market value, you may be able to seek compensation or remediation. Every case is different, and this is general information rather than legal advice.
Who do I claim against?
Your primary target is usually the installer or the company that sold and fitted the foam. If they are still trading you can raise a formal complaint directly; if they are a member of a trade body (such as the Cavity Insulation Guarantee Agency or a Which? Trusted Trader scheme) you may also be able to escalate to that body. If you financed the installation on a credit card or through a linked credit agreement, Section 75 of the Consumer Credit Act 1974 may make your lender jointly liable for the installer's misrepresentation or breach of contract. We can help you draft the relevant letters for either route.
Do I have to remove the foam before I can make a claim?
No. You do not need to remove the foam before pursuing a mis-selling or compensation complaint. You can seek redress for the financial harm caused — including property devaluation, surveyor fees, and the cost of any remedial works — without first incurring the significant expense of removal. In fact, removing the foam before your claim is settled could reduce the evidence available to you. If you do decide to proceed with removal, keep all invoices, reports, and photographs as supporting documentation.
What evidence helps my case?
The stronger your paper trail, the more compelling your complaint. Useful evidence includes: the original contract or sales agreement; any written or email correspondence with the installer; the sales literature, brochures, or online quotes you received; a surveyor's or mortgage valuer's report citing the foam as a problem; photographs of the installation and any visible moisture damage or rot; and records of any costs you have incurred or mortgage applications that have been refused. Even partial documentation is worth submitting — we will work with what you have.
