Damp, mould and condensation

Treating condensation

Everyday activities such as cooking, showering, washing and drying clothes create moisture in the air. The following steps can help reduce condensation and mould growth.

  • keep window trickle vents open where possible
  • open windows regularly to allow fresh air to circulate
  • use extractor fans when cooking or bathing
  • keep kitchen and bathroom doors closed when cooking, bathing or showering
  • put lids on pans when cooking
  • wipe moisture from windows and other surfaces
  • leave a gap of at least 50mm between furniture and external walls where possible to allow air to circulate
  • keep your home warm where possible
  • after showering or bathing, leave the extractor fan running for at least 15 minutes

Drying clothes indoors

Drying clothes indoors can add a significant amount of moisture to the air and increase the risk of condensation and mould.

  • dry clothes outside whenever possible
  • if you use a tumble dryer, make sure the room is well ventilated
  • clean tumble dryer filters regularly
  • open a window if it is safe to do so while drying clothes indoors
  • avoid drying large amounts of washing on radiators

Signs of penetrating damp

Please report any of the following:

  • water coming through walls or ceilings
  • missing, broken or slipped roof tiles
  • blocked gutters or downpipes
  • cracks or damage to external walls
  • damp patches that do not improve with ventilation and heating
