Condensation, damp and mould

Is it condensation or a different damp problem?

Moisture in the air inside your home causes condensation.

A fault in the structure of the building can also cause damp. There are two basic types of damp:

  • Penetrating damp, which happens when water enters your home through an external defect (for example, a crack in a wall or a loose roof tile)
  • Rising damp, which is when there is a problem with the damp-proof course or membrane and water rises from the ground into the walls or floor

Rising damp, leaking plumbing and rain getting to the house (through the roof or around window frames) normally differ from condensation in that they usually leave a ‘tidemark’.
