Condensation and what to do about it

Condensation

Condensation occurs when warm air that contains water vapour comes into contact with cold surfaces. The water vapour then cools down and releases the water which turns into liquid droplets.

 Causes of Condensation

Everyday activities at home can cause condensation. These activities include:

  • Cooking
  • Showering
  • Drying laundry indoors
  • Changes of temperature when using central heating
  • Breathing

 How to Recognise

  • Water droplets windows, wall and ceiling surfaces
  • Small puddles of water on window sills

You will find condensation particularly in kitchens and bathrooms. If left unnoticed or ignored, it can lead to issues such as mould growth, paint peeling, wet rot and plaster damage

What to Do

  • Use a dehumidifier
  • Use a moisture eliminator
  • Open the windows and/or use extractor fans
  • Wipe away condensation and dry the surfaces

 How to Prevent Condensation

  • Install and use extractor fans in kitchens and bathrooms – keep them maintained
  • Dry laundry outside if possible
  • Do not dry wet clothes over radiators
  • Do not have furniture up against the walls
  • During winter, keep the heating on at a constant low heat, rather than frequently switching it on and off
  • Use a hygrometer to measure humidity of the air – It should be below 50%
  • Install a whole house condensation unit
