‘I’m a window expert – here’s how to completely prevent window condensation in the winter’

John Cutts, glass expert at MeandMyGlass.co.uk said: “It’s common for people to find their windows have steamed up overnight which often results in a damp windowsill.

“While condensation may not seem like an issue, it can become a serious problem once mould growth starts to happen which can easily spread across the room.

“We recommend taking time in the morning to wipe condensation off windows, opening them up to allow for more ventilation and sealing any window cracks which could be making the issue worse.”

1. Houseplants

Houseplants including spider plants and orchids are known to help reduce moisture in the air, which can prevent condensation.

For best results, the expert recommended placing them on windowsills, close to windows which get condensation.

2. Use a dehumidifier

The expert explained: “Mould develops when there is excess moisture in the air which is why investing in a dehumidifier can help eliminate the problem.

“Having them placed on a windowsill can effectively absorb the moisture and prevent the spread from escalating.”

3. Keep windows open

While it may be hard to keep windows open all night, ventilation throughout the day can reduce indoor humidity levels.

Keeping windows open also works helping to prevent mould growth so make sure to do this as much as possible throughout the winter months.

4. Turn the heating on in the morning

Putting the heating on for around 20 minutes in the morning can help to control the humidity in the room, according to the expert.

The pro added: “Open the windows first to get a healthy airflow going, then put the heating on to stop the windows from steaming up.

“If the condensation has resulted in serious mould growth on walls and ceilings, you may need to call in professionals as it could be due to external issues in the building making it worse.”

5. Keep blinds and curtains away from the glass

If blinds and curtains are touching the glass, it can block the airflow, contributing to condensation throughout the night.

Make sure they are kept a good distance away from any windows or doors to help prevent water from building up.
