Moved into a new Wimpey house (Shenston style) last June just went up the loft at the weekend to pull down the xmas decorations and the loft was full of condensation dripping from the black underlay and mould, Beams are green with mould covering the contents of the loft. Anybody experienced this before? Got a guy coming wednesday 14th to Inspect the problem what type of questions should I be asking also what would this guy be looking to do in the way of diagnosing the problems. Any help apreciated
