Spray foam removal in Churchdown Gloucestershire done right

Damp patches on loft boards or ceilings

Foam over the eaves blocks ventilation, so moisture condenses on the cold side of the roof and drips down. It usually shows first on the boards or the ceiling below. Treat it early before the timber starts to rot.

Foam cracking or pulling away from rafters

Older foam shrinks and cracks as it ages, which breaks the seal and lets warm air reach the cold roof surface. Once it cracks, it stops insulating properly and starts trapping moisture instead.

Musty smell in the loft or upstairs rooms

A damp, earthy smell usually means trapped moisture and early mould growth on the timbers. It gets worse in winter and will not clear on its own once the ventilation path is blocked.

Mortgage lender or surveyor flags the foam

Many lenders refuse to lend on properties with spray foam in the roof because of ventilation and timber risk. If your buyer's surveyor has raised it, removal with a written report is usually the fastest way to unblock the sale.

Condensation on roof felt or windows

Water beading on the underside of the roof felt means warm moist air is reaching a cold surface. Foam often causes this by sealing the loft too tightly. A moisture meter reading confirms whether the timbers are affected.
