Loft condensation caused by trapped moisture
Why it happens here
Spray foam seals the roof space, stopping natural ventilation. In Donnington's damp climate, moisture from the house rises and has nowhere to go. It condenses on timbers and plasterboard, leading to mould and rot.
Our approach
We remove the foam, dry the loft out, and advise on breathable insulation and ventilation. A thermal imaging camera confirms no hidden damp before we finish.
