Damp and mould

Keep your house free from damp and mould

Damp can cause mould on walls, furniture and clothing.

Damp can be caused by:

  • Leaking pipes, wastes or overflows
  • Rain seeping through the roof where a tile or slate is missing, spilling from a blocked gutter, penetrating around window frames or leaking through a cracked pipe
  • Rising damp due to a defective damp course or because there is no damp course These causes of damp often leave a ‘tidemark’

If you think your home is damp, call 0300 123 5522 and request that we visit you to check if this is the case.

Condensation

Condensation occurs mainly during cold weather, whether it is raining or dry, and it does not leave a ‘tidemark’. It appears on cold surfaces and in places where there is little movement of air.

These steps will help to reduce condensation in your home:

1. Produce less moisture

  • Try to cover pans and don’t leave kettles boiling
  • Avoid using paraffin and portable, flueless bottled gas heaters as these heaters put a lot of moisture into the air
  • Dry washing outdoors on a line or put it in the bathroom with the door closed and the window open or fan on
  • Vent any tumble dryer on the outside, unless it is the self-condensing type. DIY kits are available for this

2. Ventilate to remove moisture

  • Keep a small window ajar or a trickle ventilator open when someone is in the room
  • Ventilate kitchens and bathrooms when in use by opening the windows wider
  • Close the kitchen and bathroom doors when these rooms are in use. This will help prevent moisture reaching other rooms
  • Ventilate cupboards and wardrobes. Where possible, position wardrobes and furniture against internal walls

3. Insulate, draught proof and heat your home

Insulation and draught proofing will help keep your home warm and will also cut fuel bills. When the whole home is warmer, condensation is less likely:

  • In your loft, check that you have sufficient insulation. If you feel that the insulation is not sufficient then please call 0300 123 5522 to arrange for an insulation survey. Remember to draught proof the loft hatch but do not block the opening
  • In the winter, at night, make sure you close your curtains
  • In very cold weather, keep low background heating on all day, even when there is no one at home
  • Ensure that you know how to operate your heating effectively and ask us if you are unsure
  • Do not use your gas or electric fire as the primary heat source in your home as you need to heat all rooms with your central heating system

First steps against mould

  • First, treat any mould you may already have in your home. If you then deal with the condensation, mould should not reappear
  • To kill and remove mould, wipe down walls and window frames with a fungicidal wash that carries a Health and Safety Executive ‘approval number’. Follow the manufacturer’s instructions precisely. Disturbing mould by brushing or vacuum cleaning can increase the risk of respiratory problems
  • After treatment, redecorate using a good quality fungicidal paint to help prevent mould recurring. This paint is not effective if overlaid with ordinary paints or wallpaper
