Damp and condensation

The vast majority of damp in homes is caused by condensation. Condensation occurs when there is an excessive build up of moisture in the air. People create additional moisture in their homes by:

  • Cooking or boiling water
  • Taking baths or showers
  • Drying clothes indoors
  • Using paraffin or bottle gas heaters

Warm moist air condenses and forms water when it cools, for example, when it touches a cool surface. In your home these are outside walls, mirrors, windows, wall tiles and even on clothes. If this condensation cannot dry out it will cause mould to form on walls, in cupboards and on window sills, and will cause mildew to form on clothes especially leather goods.

Your responsibilities as a tenant

  • Produce less moisture by covering pans and turning down the heat when boiling water.
  • Switch off boiling kettles.
  • Dry your clothes outside or in a well ventilated room.
  • Do not use paraffin or bottled gas heaters.
  • Close your bathroom door when bathing to prevent the moist air travelling through to other rooms.
  • Ventilate to let the moisture out, by opening a bathroom or kitchen window for a while to let the steam escape. Use an extractor fan or open the window for a while each day to change the air in your home. Use window vents that may be fitted in your home.
  • Keep your home warm by at least keeping a low background heat, this need not result in significantly increased heating costs.
