New to the forums!
I thought I'll ask the experts here as I'm not sure what is right or wrong.
We have just put up a new garden wall (2m in height) and double bricked that we think is solely on our side of the party line (it maybe 1cm over we are not sure yet).
Our neighbours have said that we should have put a damp proof in the wall as it is touching the main house (we are in a semi and they are the other half).
Are they correct is this normal procedure?
Thanks for listening! :D
