Were You Mis-Sold Spray Foam Insulation?
Many homeowners were told spray foam would save energy, add value, or cause no problems with mortgages — and only discovered the reality when they came to sell or remortgage. If that sounds like your experience, talk to us.
Common Experiences
What Counts As A Red Flag?
If any of these sound familiar, it is worth having a conversation with one of our advisors.
You were told the foam would not affect your mortgage, valuation or ability to sell.
Promised energy savings, grants or funding that never materialised.
Cold calling, doorstep sales, or no proper roof survey before installation.
No warranty, product specification or installation documentation left with you.
