Many homeowners don't realise that the problem may be hidden inside their cavity walls.
Old cavity wall insulation can become ineffective. Even worse, cavity walls often contain debris, dust, mortar droppings and other materials that trap moisture. Combined with poor ventilation, this creates the perfect conditions for damp, condensation and mould growth inside your home.
Removing failed cavity wall insulation and clearing the cavity can help your walls dry out and restore your home's thermal performance.
