Preventing damp and mould

Condensation is caused when moisture carried by warm air reaches a cold surface

Keeping your home warm and dry, by following the advice below, will help to reduce damp caused by cold surfaces in your home. 

Create less moisture and remove it with better ventilation

  • Do not use paraffin or portable gas heaters as they produce moisture when they burn their fuel.
  • Vent tumble dryers properly to the outside. Dry clothes outside whenever possible.
  • If you have a low energy extractor fan in your kitchen or bathroom, turn it on when you are cooking or washing.
  • After a bath or shower, close the bathroom door and open a window to let the moisture out.
  • When cooking, keep lids on saucepans, close the kitchen door and open a window if possible.
  • If you have 'trickle vents' in your windows, leave them open. They are specially designed to improve ventilation without creating a draught.
  • Open windows to get more fresh air.
  • Leave a gap between furniture and walls so that air will be able to circulate.
  • Keep air bricks unblocked.

Insulate your building or heat your home a little more:

  • When at home, the ideal temperature is between 18 to 21 degrees in the living rooms, and 16 to 20 degrees Celsius in the bedrooms.
  • When away from home, the temperature in the rooms should not drop under 15 degrees to avoid condensation forming on the walls.
  • Do not heat up cold bedrooms in the evening by opening the door to heated rooms. The warm and humid air will condensate on the cold walls of the bedroom.
  • Good insulation of the building helps preventing mould growth due to higher temperature of the walls. Note that airtight windows and buildings require more active ventilation.

Take advantage of available insulation grants:

If you still get condensation, you will need to remove the mould growth with a fungicidal cleaning product.
