Spray foam removal in High Green done right

Surveyor flags spray foam in the loft

This is the most common trigger in High Green. Lenders treat spray foam as a risk because it can trap moisture and hide timber defects. Once it is flagged, the sale or remortgage usually stalls until the foam is removed and the roof is inspected.

Damp patches on upstairs ceilings

Foam that blocks ventilation traps condensation, which eventually shows as damp patches or staining. If you see this in a High Green property, the foam is likely the cause. It will not dry out on its own and usually gets worse through winter.

Foam shrinking away from rafters

Spray foam shrinks as it ages, leaving gaps between the foam and the timber. Those gaps let warm air reach the cold roof surface, where it condenses. Shrinkage is a clear sign the foam has failed and is no longer doing its job.

Cold loft and higher heating bills

If your loft feels cold and your energy bills keep climbing, the foam may be blocking ventilation rather than insulating. In older High Green homes, this often means the roof cannot breathe, which causes damp and reduces the insulation's effectiveness.

Pest activity in the insulation

Rodents and insects nest in spray foam and loose insulation, especially where there are gaps and moisture. If you hear scratching in the loft or find droppings, get an assessment. Removing the foam lets us clear the infestation and seal entry points.
