Just buying a house at the moment that has had years of neglect. One of the problems is a broken guttering pipe (in fact it is just loose, but has been loose for about 15 years). This has led to water getting through the brickwork on both levels and causing really severe penetrating damp. One wall (upstairs) has been replastered in the last few years and the plaster is totally gone in the corner. The downstairs is not as bad but could still do with replastering.
The mortgage valuer has mentioned that the plaster needs to be removed and the penetrating damp treated "by a company that can offer guarantees for such work". What kind of treatment can you do to this? Is it a matter of knocking off the plaster to the brick wall, repointing outside and waiting a sufficient lenght of time for it to dry out before replastering?
Or can we just repoint, knock off and replaster with waterproofer added to the plaster mix?
Any help given gratefully received!
Not too worried about a guarantee for the work but need to know if we are missing anything here!!!
