If it's any help, Jo ............
1 Laminate.......... lifting because it's thin, and very cheap. Ask them to rip it up and throw it away.
2 Render.......... not good practice, but a minor point since I guess it's a cavity wall.
3 Damp on lounge wall ........... empty house at the wettest time of the year, and consistent diabolical weather......... any wall would show damp with one of those ridiculous meters. I would be very surprised if the dampcourse has failed, or was omitted. Surveyors love those meters. It's honestly a substitute for proper assessment.
4 Vents can be cleared... ask them to do it.
5 Garage .......... would have been OKed by the Building Inspector. It should be shown like that on the submitted drawings. It's down to the Inspector, that one. If he's happy, then no worries.
6 Sorry, I don't understand this one, but, Building Control will confirm if OK.
7 Shrinkage cracks most likely........... or possibly stress fractures between lintels (window/door openings.) .......... sadly not uncommon. The important thing to remember is that they rarely go through to the underlying masonry. A good look by someone sensible should determine the extent of the cracking
I've lost count of the times I've gone over a house after a survey, only to discount most, if not all of their findings. They are simply covering themselves as usual.
It's a sad thing today that responsibility is passed on by so many. Fear of litigation,of course, is why.
Take a trusted builder/surveyor of your own along for a candid, no-nonsense assessment. I think you'll be pleasantly surprised.
Good luck.
ps Your solicitor will ask them for the Building Regs Approval. They're in deep water if they try to sell without.
