Spray foam removal in St Mark's Gloucestershire, done properly

Damp or dark patches on upstairs ceilings

This usually means moisture is trapped in the roof void and has nowhere to go. Spray foam seals the roof, so condensation forms on the timbers and eventually soaks through the plasterboard. If you see a brown ring spreading, get it checked before the plaster fails.

A musty or damp smell in the loft

That smell is mould and damp timber. It is common in St Mark's terraces where foam has blocked the eaves and stopped air moving. The longer it stays, the more likely you are to find timber rot when the foam comes out.

Mortgage valuer has flagged spray foam

Lenders are increasingly refusing mortgages on properties with spray foam in the roof. If your valuer has raised it, you usually need the foam removed and a report provided before the lender will proceed. This is one of the most common reasons people call us.

Visible condensation on roof timbers or felt

If you can see water droplets on the underside of the roof felt or on the rafters, the void is not breathing. Spray foam is often the cause because it blocks the ventilation path. Left alone, wet timbers rot and the roof structure weakens.

Foam is cracking, peeling or falling away

Older foam can become brittle and start to delaminate from the timber. When it peels, it leaves gaps that let warm air through, so the insulation stops working. It also makes the remaining foam harder to remove cleanly, so it is better to deal with it early.
