One of the major reasons for the wet walls is the leakages. Rain water getting in between the walls is another major reason. Leakages due to improper roofing and also leakages for the pipes set within the walls have been identified as one of the major reasons.

Damp down low

If you have crumbling paint, wet patches or even powdery deposits on the wall surfaces close to the floor, rising damp may be identified as the root cause for it. This usually occurs when a damp proof course is absent in masonry walls. Sub floor ventilation and poor drainage systems have also been identified as major causes for damp on the lower surfaces. Ensure that you have proper drainage systems and anti damp measures taken on the lower surfaces of the walls to avoid this problem.


There are instances when patches start to appear on the surfaces. These patches are generally the result of water getting in between the brickwork through cracks and gaps on the outer surface. If you find any gaps, especially on the exterior walls be quick to patch them up.
