Does Your Home Suffer from Condensation and Damp?

Most damp in the home is caused by condensation.

Warm air picks up water vapour from cooking, showering and drying clothes indoors.

When the air cools it cannot hold as much vapour, so water droplets appear on cold surfaces.

If this happens frequently black mould may appear, which is unsightly and can make some respiratory conditions worse.

Ways to reduce the risk of condensation include:

  • Not letting the house get too cold
  • Having adequate (but not excessive) ventilation
  • Using extractor fans when cooking and bathing/showering
  • Drying clothes outdoors when possible
  • Keeping doors closed to rooms that produce steam – such as kitchens and bathroom

Penetrating and Rising Damp:

Other causes of damp are penetrating damp and rising damp

Penetrating Damp
Penetrating Damp

Penetrating damp occurs when poorly maintained outside walls or faulty guttering allow rainwater to enter the building. This usually appears as an isolated damp patch.

Rising Damp
Rising Damp

Rising damp appears as a large, damp area rising from the floor level. It can be difficult to cure as it often occurs in older properties built without a damp-proof course.

If your home has a damp proof course, check that it has not been bridged by paths or garden landscaping.
