Condensation and mould

What is condensation? 

Condensation starts as moisture in the air, usually from cooking, washing, or drying clothes on radiators. When it hits cool surfaces such as walls, mirrors, wall tiles and windows it condenses to form water droplets. Moist air rises when it’s warm and often ends up on ceilings and in upstairs rooms where it forms mould.

Why is it a problem? 

If condensation isn’t treated, it can cause mould growth on walls, ceilings, furniture and clothes in cupboards and drawers. It can also affect wall plaster and rot woodwork.

Condensation is arguably the most common form of dampness found in properties and can eventually lead to the growth of black mould.

How do you spot it?

  • Streaming windows and walls
  • Damp areas can appear on walls, especially behind furniture and in corners
  • Wallpaper can start to peel
  • Blackened window frames
  • Mould growth, usually black mould, starts to appear
  • Furniture and fabrics become prone to mould and mildew
