Condensation

Condensation is different to penetrating damp, which is caused by water getting into the house from outside, usually through windows, doors or roofs.

Dampness of this nature is often easier to deal with than condensation as repairing the defect in the roof, doors or window can cure it.

Rising damp occurs if there is a problem with the damp proof course (the barrier built in floors and walls to stop moisture rising through the house from the ground).

The usual evidence for this is a 'tidemark' on the walls. There can also be a musty smell.
