Condensation can lead to mould in your home.

It is most common between October and April when it is colder outside your home than inside. You can reduce the likelihood of condensation in your home by opening windows slightly to keep air circulating. You will not lose large amounts of heat.

Causes of condensation include:

  • Cooking
  • Washing and drying clothes
  • Bathing or showering
  • Lack of ventilation

How to avoid condensation

  • Close doors when cooking, washing clothes, bathing and showering.
  • Always use extractor fans provided.
  • Open bedroom windows for 20-30 minutes each morning to allow colder, drier air from outside to replace warm, moist air.
  • Keep each room in your home adequately heated.
  • Make sure trickle vents on your windows remain open.
  • Do not dry wet clothes over radiators.
  • Make sure your tumble dryer is vented externally.


If you find mould in your home, it can be a DIY job that you should be able to carry out without any professional help.

Here is some advice:

  • Remove any badly affected materials from the area (for example, throw out any damp newspapers or magazines).
  • Wear gloves and protect your carpet/flooring.
  • Walls can be re-painted with fungicidal paint.
  • Clothes or fabrics should be dry-cleaned, and carpets shampooed. Don’t brush mould as that will make the problem worse.
