Preventing damp, mould and condensation
Damp, mould and condensation can affect any home, especially during the colder months.
As temperatures drop, it's common to see more moisture on windows and other cold surfaces. This often happens in autumn and winter when we spend more time indoors, use the heating more and open windows less often.
Understanding what causes condensation and making a few simple changes can help keep your home warm, dry and comfortable throughout the winter.
What’s the difference between damp, mould and condensation?
Condensation is the most common cause of damp and mould in the home.
It happens when warm, moist air comes into contact with a cold surface, like a window or a wall. You may notice water droplets on windows, windowsills or walls, especially during colder weather.
Condensation can create damp conditions where mould can grow. Mould often appears as black or green spots on walls, ceilings, around windows or behind furniture.
Simple ways to reduce condensation:
Everyday activities like cooking, showering, drying clothes indoors and even breathing add moisture to the air.
A few small changes can help make a big difference:
- Open windows for a few minutes each day to let fresh air in
- Switch extractor fans on while cooking or bathing, if you have them
- Keep lids on pots and pans while cooking to reduce steam
- Keep kitchen and bathroom doors closed while cooking or showering to prevent moisture from spreading through your home
- Wipe away condensation from windows and windowsills when you see it
Keeping your home warm
We understand that many households are trying to keep energy bills down. However, very cold homes are more likely to experience condensation, damp and mould. You can find our top tips for getting the most out of your heating here!
Drying clothes indoors
Drying clothes indoors can add a lot of moisture to the air.
Where possible, dry clothes outside. Even during colder weather, a crisp, dry day can be ideal for drying laundry!
If you need to dry clothes indoors:
- Choose a room with a window slightly open or an extractor fan running
- Keep the door closed to stop moisture spreading into other rooms
- Avoid putting clothes on radiators to dry
Don’t forget ventilation!
It can be tempting to cover vents to keep warm air inside, but good ventilation is important for removing moisture from your home.
Check that any air vents, air bricks and trickle vents in windows are open and clear.
Give furniture some space
Large pieces of furniture placed against external walls can trap moisture and restrict airflow. Where possible, leave a small gap behind wardrobes, sofas and cupboards to help air circulate.
