Our house dates from 1850. A stretch of ground floor hallway wall has been damp ever since we moved in 5 years ago.
The wall is a mixture of brick and stone with no damp proof course. The area outside is a small courtyard belonging to our neighbour (not accessible from our property). Every time we get a lot of rain, water gets trapped in this area, then we notice that the walls feel damp especially at the bottom. Paint has flaked off and brass coated sockets have corroded.
A damp and timber report carried out when we moved in suggested that hanging baskets were to blame (hung on the wall by our neighbour). This does not seem likely as the damp is mainly at the bottom of the wall.
The advise given was to replaster.
So we did! Guess what.....the paint is flaking again. Any advise on what we really should have done is very welcome.
Thanks in advance.
