Poor air flow is usually a big part of the problem, because it prevents damp from evaporating harmlessly away. So if any vents or airbricks are blocked, they have to be cleared.

Condensation Damp

However, the reality is that true rising damp is extremely uncommon. Wetness in decrease partitions is often as a result of different causes, such as condensation on steamy home windows working down the wall and soaking in, or raised flower-beds or paving stones permitting damp to get previous the damp-proof course.
