Selling A Home With Spray Foam Insulation
Essential guidance for homeowners trying to sell properties with spray foam
Selling a home with spray foam insulation has become increasingly challenging. Many UK homeowners discover that their spray foam—once considered an asset—is now a significant barrier to completing sales. This guide explains why and what you can do about it.
The Reality: Most Sales Fall Through
The unfortunate truth is that most property sales involving spray foam insulation fail at the mortgage stage. Here's what typically happens:
- •Property goes on the market
- •Buyer makes an offer
- •Mortgage surveyor identifies spray foam
- •Lender declines the mortgage application
- •Sale collapses
Why Lenders Reject Spray Foam Properties
Hidden Timber Damage
Spray foam prevents visual inspection of roof timbers, making it impossible to assess structural condition or detect rot.
Moisture Trapping
Improperly installed foam can trap moisture, leading to timber deterioration and expensive structural repairs.
Removal Costs
Lenders know that buyers may face £3,000-£20,000+ in removal costs, affecting long-term property value.
Lack of Standards
No consistent industry standards exist for spray foam installation, creating uncertainty about quality and safety.
