Spray foam removal in Bocking's Elm done right

A lender or surveyor has flagged the foam

This is the most common trigger on the estate. Lenders treat spray foam in a loft as a risk because it can trap moisture and hide timber defects. Once it is flagged, the mortgage usually will not complete until the foam is removed and the loft is inspected, so this is urgent.

Condensation running down the rafters

Water beading on the underside of the roof or dripping onto stored items means the foam is acting as a vapour barrier in the wrong place. Moisture from the house cannot escape, so it condenses on the cold timber. Left alone, this leads to rot.

Damp patches or staining on ceilings

Brown staining on an upstairs ceiling often points to moisture sitting against the roof structure above. On Bocking's Elm homes with foam-filled lofts, this usually means the timber is wet and the problem has been building for months. It needs checking with a moisture meter.

A musty smell in the loft or upstairs rooms

A persistent damp, earthy smell in the loft space is a sign of trapped moisture and early timber rot. Foam stops the roof breathing, so the smell gets stronger over time. By the time you notice it downstairs, the timber is often already affected.

Foam has been in place for over ten years

Foam installed more than a decade ago has had time to trap moisture and cause hidden damage. Even if you have not noticed a problem, a survey with a boroscope inspection camera will show whether the rafters are sound. It is worth checking before you sell or remortgage.
