Spray foam removal in Lansdown Gloucestershire done right

Surveyor flags spray foam in the loft

This is the most common trigger in Lansdown. A lender's surveyor sees foam against the rafters, notes the risk of trapped moisture and roof ventilation blockage, and the mortgage is held up. Acting quickly keeps a sale on track, and a proper removal report usually satisfies the lender.

Condensation or damp patches below the loft

Foam sprayed onto the underside of slates blocks roof ventilation, so warm moist air has nowhere to go. In Lansdown's period homes this shows up as condensation on bedroom ceilings or damp patches on chimney breasts. Left alone, it leads to timber rot.

Musty smell in upstairs rooms

A persistent musty smell upstairs usually means trapped moisture is feeding mould on hidden timbers. Spray foam hides the problem because water cannot pass through it. By the time you smell it, the foam has often been holding damp against the rafters for several winters.

Rafters feel soft or spongy

Press a rafter near the foam and if it gives, rot has started. This is urgent. Rot spreads along the timber and into the roof structure, and what starts as a removal job can become a structural repair. We check every rafter with a moisture meter during the survey.

Foam is cracking, shrinking or pulling away

Older spray foam can shrink and separate from the timber, leaving gaps where air and moisture move freely. It no longer insulates properly and it still blocks ventilation. In Lansdown we see this most in lofts foamed more than ten years ago, and it is a clear sign removal is due.
