I have some damp is which eight feet off of the floor in the kitchen and which I think is as the result of worn-out bricks or poor pointing (although it still looks okay from the oustide and my NON-builder eyes!) which has come through a nine-inch NON-cavity wall. There is no damp coming from the room above, so that rules that one out! One builder suggested a quick fix with two coats of Thompson Waterseal (about £30) to seal the wall, although as I do not plan to move soon this may not be the best option. I feel that I have read somewhere that covering bricks with a sealant is not a good idea too? Any advice?
