What is condensation?
- It starts as moisture from cooking, washing or drying clothes indoors on radiators.
- The moist air condenses on cool surfaces such as walls, mirrors, wall tiles and windows, and even some clothes.
- When the moist air is warm it rises and often ends up on ceilings and in upstairs rooms. It’s then that mould starts forming.
If mould starts:
- Wipe the mould off immediately with water. Do not use washing up liquid.
- Apply a mild bleach solution to the wall or use a recommended product available from a DIY store.
Trying to stop condensation
Condensation can start in any home. You can do things to stop it happening.
Control excess moisture:
- Close kitchen and bathroom doors to stop steam going into other colder rooms.
- Open kitchen and bathroom windows when cooking or washing to let the steam out, or use an extractor fan if you have one put in.
- Open some windows in all the rooms in your home for a while each day, this will allow for a change of air.
- Wipe down surfaces where moisture settles to stop mould forming.
- If you use a tumble drier, vent it directly to the outside.
- Use window trickle vents where these are provided.
- Do not block, take away or cover air vents.
- Do not switch off automatic kitchen or bathroom extractor fans.
- Do not use bottled gas or paraffin heaters – these produce a lot of moisture and your tenancy agreement says that you are not allowed to use these.
- Do not use your cooker to heat your home.
How to produce less moisture:
- Dry clothes outdoors whenever possible, otherwise use well ventilated rooms.
- Cover pans when cooking.
- Vent any tumble driers to the outside.
Keep your house warm:
- Take steps to stop heat loss in your home.
- Keep low background heat.
