Like others, our house has minimal damp, mostly caused by poor sealing around the window frames (bringing Mastik with me on next visit). Ours is not for sale - not this year anyway.

damp caused by rainwater ingress is totally different to rising damp, which is caused by water in the surrounding ground being drawn up the walls by capillary action.
Damp due to badly draining balconies etc. is easily rectified by improving the drainage of the balcony or surrounding area, usually caused by the fact that most houses here seem to have their balconies tiled with the fall towards the house and not away !! so re-tiling with a fall away from the house usually cures the problem caused by rain water.
Rising damp needs some sort of physical or chemical barrier to stop the capillary action as it will continue to pull the damp all year regardless if it rains or not, hence the need for some sort of injection treatment with a suitable barrier if it is truely rising damp causing the problem.
Hope this helps to clarify the difference between the problems.
