Buying a house with rising damp can be worrying, but you can permanently get rid of it. You can install a new damp-proof course, but you should factor in the cost of corrective work and any redecorations.
Alternatively, you can ask to renegotiate your offer but to do that; you will need proof that there is a damp problem on the property, which will cause extra expenses. We always recommend getting a damp and timber survey.
