Preventing damp, mould and condensation in your home

Damp, mould and condensation have a big impact on your home and your health.

Below you’ll find out about condensation and how this can lead to damp and mould, but most importantly how to prevent this in your home.

What is condensation?

There’s always moisture in the air, even if you can’t see it. Some of this moisture can be created by day-to-day activities such as cooking, washing, and even breathing. If humid air meets a cool surface, like a window or wall, condensation will form.

How does condensation lead to mould?

When condensation regularly forms on a surface, mould can grow. This most commonly occurs in bathrooms, kitchens, behind furniture and around window frames. This can not only be very bad for your home, but also your health, particularly if you have asthma or other health issues.


What can we do to help prevent damp and mould forming in our home?

Heat your home efficiently

- Condensation occurs more often during winter. Try and make sure all your rooms have suitable heating*

- In cold weather it’s better to keep the heating on at a constant low level**, rather than putting it on in short, high bursts. Try not to let the temperature drop below 14 degrees

- Don’t try to warm an unheated room by leaving the door open to a heated room – the warm air will enter the cold room and condense on cool surfaces.

**Keeping your home at a constant temperature might sound expensive but takes less energy than warming it once from a cold temperature. Compare it to boiling a kettle – to boil from cold takes a few minutes but it’s quicker to boil again when still warm, so uses less energy.

Reduce moisture in the air

-When cooking, open a window or use an extractor fan, and keep the kitchen door closed. Keep lids on saucepans when you cook

-When taking a bath or shower, open a window or use an extractor fan, and close the bathroom door. Keep the door closed afterwards to stop moist air spreading

-When running a bath, put cold water in first then add hot – it reduces steam by almost 90%

-Dry clothing outside where possible. If you can’t do that, use a room with the window open and door closed – and don’t put clothes on radiators to dry

-If you use a tumble dryer, make sure it has a ventilation pipe leading outside

-If you see condensation forming, don’t worry – simply wipe it away with a clean dry cloth and open the window

Increase air flow

-Open windows to let the air circulate

-Avoid putting too many things in cupboards, as this limits air circulation

-Leave about two inches of space between furniture and external walls, so air can circulate
