Spray foam removal in St Paul's Gloucestershire done right

Damp patches on upstairs ceilings

Foam that has sealed the eaves stops the roof space from breathing, so condensation forms on the underside of the felt and eventually tracks down onto the ceiling below. By the time you see the patch, the timber behind it has usually been wet for months.

A surveyor or lender flags the foam

Mortgage lenders treat spray foam under a roof covering as a risk because it hides the timber and blocks ventilation. If a valuation has been refused or put on hold, removal is usually the fastest route to getting the lending back on track.

Foam is cracking or pulling away

Older foam goes brittle and starts to separate from the rafters. Once it cracks, it stops insulating properly and can drop onto the loft floor. It is also a sign the bond has failed, which can make removal easier than expected.

A musty smell in the loft or landing

That smell is damp timber and stagnant air. In St Paul's terraces the loft hatch often sits over the landing, so the smell drifts into the house. A moisture meter reading above 20 percent at the rafters means the roof needs to dry out.

Condensation on roof felt or tiles

If you can see water beading on the felt from inside the loft, the ventilation path is blocked. Left alone, that moisture rots the battens and rafters and can eventually reach the plasterboard. It needs removing before the next cold spell.
