Managing condensation & mould: a guide for residents

During the cold winter months, you may notice condensation on your walls and ceilings. Although condensation is normal, if it is not cleared it will lead to damp and mould. In this article, we explain what condensation is, what to do if you see mould in your property and tips on how to prevent it.

What is condensation?

Condensation is formed when there is excess moisture in the air. There is always some moisture, but as the air gets colder during winter, and windows are opened less, tiny drops of water appear on cold surfaces and walls. If condensation appears on windows or other surfaces, it is important to wipe it away every day. If the condensation doesn’t evaporate or is not cleared, then mould may start to grow.

How to prevent condensation in your home?

There are some simple things that you can do to reduce condensation in your home and avoid mould growing:

  • If condensation appears on windows or other surfaces, wipe it away every day.
  • Keep bathroom and kitchen doors closed during and after cooking, bathing or showering, open a window and use the extractor fan to ventilate the room.
  • Place lids on boiling saucepans.
  • Keep the property ventilated as much as possible by opening a window in each room for a short period of time each day. If you have trickle vents on your windows, keep these open as much as possible.
  • Dry clothes outside if you can. If you can’t, dry them on an airer in a room with the door closed and a window open. Avoid putting wet clothes directly on the radiators. Using a dehumidifier when drying clothes can also help.
  • Leave a space between the back of your furniture and the wall to allow air to circulate.
