Remove Failing Cavity Insulation and Protect Your Home

Poorly installed or waterlogged cavity wall insulation can cause serious problems. It traps moisture, leads to cold internal walls, encourages mould growth and can cause long term structural damage. Many homes across Cornwall suffer from damp issues due to failed insulation and incorrect installation.

Ridgedown provides professional cavity wall extraction to remove the insulation safely and restore the natural ventilation your walls need. Once removed, your walls can dry properly and future damp issues can be prevented.

This service is ideal for homeowners dealing with unexplained damp, cold patches, mould, survey problems or older insulation that has degraded.
