Spray foam insulation failing building regulations
Why it happens here
Many Brent lofts had spray foam installed years ago without proper ventilation or building control sign-off. Under Building Regulations Part L, that foam can fail the energy performance assessment, which is why lenders flag it during a sale.
Our approach
We remove the foam, check the roof structure and leave the loft in a state that can be reassessed. We also provide a written summary of the work and the condition of the timbers, which is what a surveyor needs to sign it off.
