Getting rid of condensation in a house

Condensation is formed when moisture comes into contact with a cold surface. It encourages the growth of mould on walls and ceilings and causes woodwork to rot. Here are some simple ways to prevent and protect your house from condensation.

Level of difficulty

Level 1: Beginner

Things you’ll need

Dehumidifier
Bleach
Rag
Extractor fan
Insulating plasterboards

The steps to follow

  1. When you’re cooking or washing, keep the kitchen or bathroom doors closed to stop the steam from entering other rooms
  2. To allow warm air to escape, open the windows in that room and close the door
  3. For better ventilation, leave the windows and doors slightly open while you’re sleeping. A person releases half a pint of water as vapour in their sleep. This vapour is another cause of condensation on windows in the mornings
  4. Clean airbricks or ventilators. Air circulation, airbricks and ventilators are vital in helping to get rid of moisture in the air. Airbricks are important in rooms that have fuel-burning appliances. Without airbricks, these appliances will burn inefficiently and toxic fumes can get trapped
  5. Wipe condensation from window sills, tiled walls and shower stalls to prevent condensation black spots. Wash any spots that do appear regularly with bleach and water to prevent mould from growing
  6. Install an extractor fan in the bathroom and kitchen window, wall, or ceiling. The extractor fan should be powerful enough to extract air and ventilate the room
  7. Less condensation will form when cold surfaces are kept warm
  8. Install double-glazing to windows to cut down condensation
  9. Cork, blown vinyl wall coverings and paper backed fabrics are better options on exterior walls than paint or ceramic tiles
  10. Try lining insulating plasterboards on exterior walls for better insulation reducing the risk of condensation
  11. Use a dehumidifier to dry and warm the air
