There is always moisture in the air even if you cannot see it. It may cause mould, damage to clothes, furnishings and decorations.

When the air gets colder it cannot hold all the moisture, and tiny drops of water appear. This is called condensation. You may notice condensation when you see your breath on a cold day or when the mirror mists over when you have a shower.

Condensation happens more in rooms where there is a lot of moisture, such as bathrooms and kitchens.

Why does it happen?

There are 4 main causes of condensation:

  • excess moisture produced by everyday activities
  • inadequate ventilation.
  • insufficient heating
  • insufficient insulation.

What you should I do if I find mould in my home?

Preventing condensation is about getting the right balance by reducing excessive moisture, adequate ventilation, sufficient heating and sufficient insulation.

For further guidance, see our leaflet: All about preventing condensation.
