I've recently bought a new house with an old early 1900's cottage (just one large room now) attached to it. It has a full DPC under the concrete floor and the stone walls were injected near the base, as well. The exterior of the walls are unrendered stone and I do not want to cover the walls with anything as it will take away from the look completely. The house has been empty and unheated for over a year and a lower level of the house was flooded on 1st November last. The water was pumped out and it has been dry since. However, relative humidity in the house is about 85% - 90%, the cold weather making this worse. The problem is that the inside walls of the cottage are quite damp and I'm unsure if this is simply due to the very high humidity together with it being winter and also that the walls affected face south west, where most rain blows from. I am getting insulated dry lining installed shortly and I don't know whether I need to build a new stud wall with an additional DPC to stop the damp penetrating....Or is it simply residual dampness in the walls from the flood and due to the time of year??? Should I wait until I get the heating up and running to dry out the house before I build a new internal wall and lose quite a bit of floor areas? Thank you
