Hi, I've recently bought a corner terrace that's on the bottom of a hill and the side that faces the slope suffers from a few different types of damp as far as I can tell. I bought my house about six months ago knowing that it had a damp problem, but that was reflected in the price. So the first thing I did was to spend some money to get the problem wall re-rendered up to a metre high with a water retardent. At the same time I had an internal and external damp proof course installed - belt and braces such is my desperation. The first type of damp seems to occur where the external path is higher than the internal floor which happens for about a third of the way until the slope eventually peters out. The damp seems to be contained in the vertical distance between the internal and external damp proof courses. As far as I can tell the council should be responsible for this as it's their mud resting against my property, even if the path was laid a generation ago! Am I right? What can I practically do?? The second type of damp occurs in the old plaster above the metre high rendering and I've been told it can't be rising damp that high. But what can it be? Another theory I've heard is that the soot particles from the old chimney breasts (removed a long time ago) are somehow holding onto water. But shouldn't they dry out eventually? The plaster is again dry for the final third nearest the ceiling so I get this damp middle stripe running from left to right. I'm at my wits end, any suggestion will be welcome.
