thanks bizzylizzy. We were advised that even though a full structural survey is more in-depth, they still don't check everything you may assume they would, and unless your property has had major alterations or is very run-down, its probably not necessary to have. That's why we thought of the homebuyers but then get additional surveys for any areas we suspect may be problematic - such as the damp and timber. Just watch out - we have friends who had a full survey on their victorian house, and now a year after moving in they have discovered extensive dry rot, which must have been there at the time of the survey, and have been through hell trying to get it eradicated. Of course they're trying to prove that the surveyor was negligent, but because the rot was under the floor and behind the plaster, these are not places the surveyor specifically looked. So check the small print in the surveyors contract !
