Condensation is one of the main causes of damp and mould. It happens when warm, moist air meets a cold surface and turns into water.

This can happen all year round – whether in summer when the air is humid, or in winter when we heat our homes and keep windows closed. Everyday activities like cooking, washing, and drying clothes indoors add extra moisture to the air.

The good news is there are simple steps you can take to manage condensation and keep your home healthy, no matter the season.

 

Keep moisture down

Use lids when cooking and keep kitchen doors closed to stop steam spreading.

Avoid leaving the kettle or pans boiling for too long.

When bathing or showering, keep the door closed and open a window or use an extractor fan.

Dry clothes outside, when possible, but if it’s too cold or wet, use a drying rack near an open window instead of radiators.

 

Ventilate your home

Let fresh air in, especially in rooms where you create more moisture like kitchens and bathrooms to stop it from turning into condensation.

Open several windows at the same time to help air flow through your home.

Try opening windows and doors for a short time each day.

In colder months, open windows for a few minutes a day while heating your home to remove moisture.

 

Wipe away condensation

Mould grows on wet surfaces, so:

  • wipe down windows, windowsills, tiles, shower screens, and walls regularly with a cloth
  • make sure the area is dry after wiping

Leave space for air to move

Mould can grow behind furniture where air can’t circulate, so:

  • keep large furniture slightly away from walls
  • avoid storing lots of items against the walls

Keep rooms warm (especially in winter)

Very cold rooms can create the perfect conditions for mould. Try to keep your home above 14°C.

The ideal temperatures are:

  • living rooms: 20°C
  • bathrooms and children’s rooms: 23°C
  • bedrooms and kitchens: 16°C
