Why Remove Spray Foam?
Mortgage Issues
Most UK lenders now refuse mortgages on properties with spray foam, making selling or remortgaging impossible.
Insurance Refusal
Insurers increasingly decline coverage due to hidden damage risks and reduced property value.
Property Devaluation
Spray foam can reduce value by £20,000-£50,000+ due to lender restrictions and buyer concerns.
Structural Damage
Foam can trap moisture, prevent ventilation, and hide timber rot until extensive damage occurs.
