Expert Guide to Spray Foam Insulation Removal in London
Are you worried about the impact of spray foam insulation on your property’s value or mortgage eligibility? You’re not alone. Thousands of UK homeowners are discovering that spray foam, once seen as a modern upgrade, can create unexpected headaches—especially when it comes to selling, remortgaging, or complying with building standards. If you’re in London and facing the challenge of spray foam removal, this guide is for you.
Why Spray Foam Insulation Removal Is Becoming Essential
Spray foam insulation, while effective for thermal performance, has become a major concern in the UK housing market. Recent RICS (Royal Institution of Chartered Surveyors) guidance warns that spray foam can conceal roof issues, affect breathability, and even void mortgages. In fact, a 2023 RICS survey found that one in five UK lenders now refuse mortgages on homes with spray foam insulation unless it’s professionally removed.
When Should You Consider Spray Foam Removal?
You should consider spray foam insulation removal if:
- You are struggling to sell or remortgage your property
- Your loft or roof space shows signs of damp, mould, or timber decay
- You need to comply with the latest UK Building Regulations and RICS guidance
- You want to restore your property’s value and eligibility for financial products
