Hi, I live in a 1950's block built semi-detached house and suffer from damp and condensation in all three bedroom and desperately looking for idea's on how to cure it! The house has double glazing ( no air vents), it has airbricks up in the corners of all bedrooms which have been blocked up on the inside only(the house is on a busy road so blocked to reduce noise!), there is very little loft insulation above. Also the outside of the house has been coated in a black bituman looking paint, then painted over. The house is gas centrally heated. Any idea's please!!!!!
