I’ve dealt with the NHBC and it was a less than pleasant and helpful experience.
Dear wrightyson, “The best thing about the Nhbc warranty is that it will have been properly inspected during construction. “. Well the bloke who inspected mine was a bit shortsighted as he didn’t spot the missing lead flashing on the roof joins. Hence the conversation with the NHBC, however I can reliably inform you that a house that leaks when it rains is legally structurally sound.
Sue, have you got any building/trade/practical mates, as I’d ask them, the mortage survey will simply establish arse sorry cost covering ability (*and not spot damp, etc etc) and a full building survey will cost LOTS. (*edit – can you ask the neighbours if they’ve had any problems, I would, also can you get an ins quote and try to work out if it’s loaded – ins companies have a subsidence database – postcode risk system)
