Condensation and mould

Why do I get condensation?

Everyone's home gets condensation from time to time, usually when cooking, bathing or if air is not able to circulate freely. Moisture and steam is produced and when this damp air comes into contact with a cold surface such as walls, ceilings, mirrors or windows it condenses back to water. Too much condensation in your home encourages mould and mildew to build up and grow. This can leave unsightly black stains on your walls and corners of rooms. The presence of condensation and mould growth doesn't mean there is anything wrong with the building. Did you know an average family produce about 105 litres of moisture every week just from their normal activities? That's nearly two baths full of water!

Things you can do to reduce condensation:

  • cover pots and pan when cooking
  • keep air vents and extractor fans clear
  • dry clothes outside if possible
  • if you have to dry clothes inside ensure it's in a well ventilated room or if you use a tumble dryer ensure it's vented outside
  • ventilate to reduce moisture - use extractor fans when bathing and cooking, or open a window when finished until the windows are clear
  • allow space for air to circulate around furniture, especially against outside walls
  • don't block radiators with furniture or curtains.
