Ways to help prevent condensation and mould

Having a well-ventilated home (for example by opening your windows) and keeping the heating on are two of the best ways to prevent issues with mould.

During the winter, we know you might want try to shut the cold out by keeping your windows closed and not rely too much on central heating, but it’s important to get the balance right.

The good news is that there’s lots of practical things you can do to prevent both condensation and mould:

  • Keep your home ventilated. Change the air by opening a window for a small amount of time each day. Keep window vents open, and air vents uncovered.
  • Turn on the extractor fan in your bathroom to reduce moisture. They use less energy than a lightbulb!
  • Keep doors inside your home closed and windows open when washing and cooking.
  • When filling a bath, run the cold water before the hot water to reduce steam.
  • When cooking, keep lids on pots and pans to prevent moisture escaping.
  • Wipe off any water droplets on windows when they appear.
  • Dry clothes outdoors, or in a room with the doors closed, windows open and the extractor fan on. If you’re using a tumble dryer, make sure the ventilation pipe runs to the outside of your home.
  • Where possible, leave a gap between walls and furniture to allow air to circulate.
  • When using your heating, keep it at a constant temperature.
  • Use a fungicidal spray on areas already affected by mould.

Support with the cost of living

We know the increased cost of living is likely to make issues with damp and mould worse, as people find it harder to heat their homes during the winter months.
