Spray foam removal in Rettendon done right

A surveyor or valuer has flagged spray foam

This is the most common trigger in Rettendon. Mortgage lenders treat spray foam in a roof as a risk because it can trap moisture and hide rot. If your valuer has raised it, you will usually need to remove the foam before the lender will proceed.

Damp patches or condensation in the loft

Foam blocks ventilation, so moisture from the house has nowhere to go. It condenses on cold rafters and drips. In older Rettendon cottages this often shows as dark patches on the timber or mould on stored items.

A musty smell in upstairs rooms

If the roof space is damp, the smell finds its way into bedrooms and landings. It is a sign that moisture is sitting against the timber. Left alone, it leads to rot and potentially structural damage.

Soft or crumbling roof timbers

Press a screwdriver into a rafter and it should feel solid. If it sinks in or crumbles, rot has set in. This is common in Rettendon roofs where closed cell foam has been in place for years without ventilation.

Higher energy bills than expected

Spray foam is sold as insulation, but once it is wet it stops working. If your loft feels cold or your bills have crept up, the foam may be saturated. Removing it and reinstating proper ventilation often fixes the problem.
