So obviously we'd need to have a surveyor in, I'm just trying to work out whether it's worth spending the money or it's such a money pit we should run away screaming rather than pay a surveyor.

Built in 1934, stone cottage, rendered later. There are what look to me like damp patches under the window sills and on some walls, so paint has bubbled and wallpaper is peeling, but it all feels completely dry to us. Anyone have an opinion on it?

We have a mid 19th century granite house. Surveyor noticed some damp and marked it on the survey. We got an additional report from a damp person (no idea what the proper name for them is) and he was able to look at it, so far as possible, and identify that it was caused by a minor problem around our door (about £500 to replaster) and the construction of the house, which was liable to be damper than modern non-granite houses. He recommended a specific type of plasterboard when we decorated (still getting the cash together for that 2 years later and no obvious signs of damp).

So two things:
(1) old stone houses are going to have a different level of damp to modern-built brick ones (or so I'm told)
(2) you can get a specific damp report, before spending money on a full survey.
