We are in the process of looking for a new house and have seen one we like so had a look at the survey on it. The only thing flagged up that we weren't aware of is that there is evidence of woodworm in the attic timbers. I've had a look at a couple of exterminator's websites and they are a bit vague about the costs involved, has anyone had their attic treated for woodworm and was it reasonably cheap?
