3. Ventilation of the home

You can help reduce condensation that has built up overnight by “cross-ventilating” your home. You can do this by opening a small window upstairs and a small window downstairs, ideally on opposite sides of your house or diagonally opposite if you live in a flat.

At the same time, open up the interior room doors – this will allow drier air to circulate throughout your home. You should try to do this for about 30 minutes each day.

If you have trickle vents in your windows (they are usually either above or in your window frames), keep them open.

Note that you should be careful not to over-ventilate your home when it is cold as it will cause the temperature inside to drop and increase the chance of condensation occurring.
