Spray foam removal in Little Clacton done right, first time

A surveyor has flagged spray foam

This is the most common trigger. Lenders treat foam in lofts and cavities as a risk because it can hide rot and block ventilation. If your mortgage or a buyer's mortgage has been refused, the foam usually has to come out before anyone will lend on the property.

Damp patches on inner walls

Injected cavity foam can bridge the gap between the two leaves of the wall, letting damp travel across. You will see it as a patch on an inside wall, often low down or near a corner. It gets worse over winter and will not dry out while the foam is in place.

Condensation and damp in the loft

Foam sprayed tight against rafters stops the roof space breathing. Moisture builds up, you get condensation on cold surfaces, and over time the timber darkens and softens. A moisture meter reading above 20 percent on a rafter is a warning sign.

A musty smell upstairs

Trapped moisture and early timber rot give off a damp, musty smell. If a spare room or landing smells worse in the morning, the loft above it may be the source. It is worth a boroscope inspection before the rot spreads.

Visible dark staining on rafters

Dark streaks or black patches on roof timbers mean water has been sitting there. Foam often hides the worst of it, so what you can see is usually only part of the picture. The sooner it is removed and the timber treated, the less structural work is needed.
