My first time posting on these forums and I'm looking forward to expert input.
Two or three years ago we had our house re-roughcast. When the guys were finishing they covered what had been brick painted with something that looked like tar with a render to match the base coat of the msin roughcast. Since then I've sometimes had the feeling that an internal cupboard has been very cold and slightly musty smelling. Just recently though, after the heavy wind and rain there is a dicolouration and a damp feel on the internal wall and a definite staining on the outside wall.
My main question is, as the lower render bridges the damp course, is water being drawn up from the soaking wet grounnd and then into the house.
Any opinion or advice will be gratefully received.
