How to prevent condensation and mould

Reduce mould and condensation in your home with these simple steps.

What is condensation?

Condensation is when moisture or water in the air collects on a cooler surface. Most people have a little bit of condensation, like the droplets you see on your windows after a shower.

While it’s usually nothing to worry about, condensation can lead to damp and mould if left for too long. Mould looks like little black dots in the corners of the windows or anywhere water collects. Mould can be bad for your health, so it's important you take action if you spot signs of mould in your home.

Sometimes, damp and mould is due to an issue with your property. If you have tried our tips but it's not making a difference, please let us know. It could be that we need to carry out some maintenance. If this sounds like you, then please report your damp or mould online.

Preventing condensation and mould

If your windows are getting steamy or your window ledges are wet then there’s too much moisture in the air. Here are some tips to help you prevent condensation and mould in your home:

Condensation step 1

Step one

Set your heating to come on for a longer period but at a lower temperature; spikes in temperature from very warm to very cold create the perfect conditions for condensation to form.

Condensation step 2

Step two

Make sure you always have your extractor fans on when you’re in the shower or bath, or when you’re cooking, and keep the kitchen or bathroom doors closed too.

Condensation step 3

Step three

Wipe water away from windows to avoid mould.

Condensation step 4

Step four

Open windows when you can to let fresh air in and moist air out - especially first thing in the morning.

Condensation step 5

Step five

Dry your clothes outside, if you can - if that’s not an option then think about drying them in the bathroom or kitchen, keep the extractor on, a window open and the doors closed.

Condensation step 6

Step six

Make sure your furniture is away from radiators and external walls as this stops air moving around your home.

Condensation step 7

Step seven

Keep lids on your pans when you’re cooking to stop steam escaping.

Condensation step 8

Step eight

If you have a tumble dryer, make sure it’s ventilated outside.

Condensation step 9

Step nine

If you do get mould, use a mould cleaning product to remove it.
