I need some advice from anyone who has first hand experience of damp problems and fixing them. I've just had a habitation check done on a prospective purchase and it was found that a vent (blanked off from a previous heater installation) had been leaking. The damp meter identified a small area about 12 inches wide by 4 to 5 inches high at the base of the wall around this vent (circular blanking plate - see picture). The vent was removed and resealed. The examiner said that it would dry out gradually and not to worry about it. This was at a local motorhome dealer. I could feel a small area, maybe 6 inches by 1/2 and inch which was a little soft right at the base of the wall directly under the vent. His explaination seemed plausible given the evidence. The rest of the van was ok. Would this be a deal breaker? Do things dry out as I have been told (given that there is no more water ingress). This is a private purchase and it is a good clean van, the best I have seen so far. It is a 2006 Autocruise Starfire. No doubt people have damp problems and they get fixed. But just how concerned should I be?
