I have cavity wall insulation in my ex authority house. It is wet, i believe, it is why i have mould issues indoors. Does anyone know what i can do/have done to remedy the wet insulation ? The insulation was put in by the authority approx 10 yrs ago, approx a year before i purchased it. The wet insulation was found when an area of outer wall was removed to enable builders to install a damp tray for my disabled daughters ground floor bedroom & bathroom. any suggestions/advice would be great, Thanks in advance.
