Damp and mould

No one wants to live in a damp home. Damp can cause mould on walls and furniture and cause wooden window frames to rot. It's also unhealthy.


Some damp is caused by condensation. This can lead to a growth in mould that appears as a cloud of little black dots. For other kinds of damp, see below.


Condensation occurs when moist air comes into contact with a colder surface like a wall, window, mirror etc. The air can’t hold the moisture and tiny drops of water appear. It also occurs in places the air is still, like the corners of rooms, behind furniture or inside wardrobes.


An easy to read guide for dealing with damp and mould in your home is available online on the Centre for Sustainability website.

Helpful tips

  1. During winter months and cold snaps keep a constant temperature of above 18 degrees in your home
  2. Treat existing areas of mould growth with fungicidal washes - Mould does not grow on dry surfaces so it is really important that you wipe off any condensation from your windows or surfaces every morning to stop mould growing.
  3. Keep doors closed while cooking or taking a bath/shower - After taking a bath or shower there will be excess moisture in the air. To stop condensation forming, keep the bathroom windows open and extractor fans turned on.
  4. Reduce moisture in your home by avoiding drying clothes inside - Dry clothes outside if you can. If you can’t, put them in a closed room and keep the window open.
  5. If you use a tumble dryer make sure that the ventilation pipe runs to the outside your home
  6. Air your home by using extractor fans and trickle vents if your home has them - Keep your home well ventilated by opening windows every day to ensure regular air changes. You should also make sure that trickle vents in your windows are open to allow additional airflow. If you have condensation on your window it is likely that it will be elsewhere in your property.
