Complete UK Resource
This comprehensive guide covers everything UK homeowners need to know about spray foam removal: why it's necessary, how it's done, what it costs, and how to choose the right specialist.
Why Spray Foam Must Be Removed
Mortgage Restrictions
70-80% of UK lenders refuse mortgages on properties with spray foam insulation.
Affected lenders: Nationwide, Halifax, HSBC, Santander, most building societies
Insurance Refusal
Home insurers increasingly refuse coverage or charge 300-500% higher premiums.
Impact: Property becomes uninsurable or prohibitively expensive
Property Devaluation
Spray foam reduces property value by £20,000-£50,000+ or makes homes completely unsellable.
Reason: Limited to cash buyers only, eliminating most market
Hidden Timber Damage
Foam prevents inspection and can trap moisture, causing rot and structural deterioration.
Risk: Damage discovered too late, costly repairs needed
