How to stop your windows steaming up in the morning to prevent mould

Brits are being advised on how to eliminate condensation on windows to prevent mould outbreaks in their homes.

The glass specialists at are offering tips on how to prevent windows from steaming up on cold Autumn mornings.

In the colder months of the year, indoor air tends to be warmer and more humid which results in more moisture in the air compared to outside.

When the warmer indoor air meets the cold windows, it can cause condensation to form on the glass.

A heavy amount of condensation can lead to dampness which can then spiral into mould growth on blinds, walls and ceilings.

Keeping the windows open and wiping them down with paper towels can stop a build-up of condensation to help prevent mould growth.

John Cutts, glass expert at 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.”

Here are eight ways to reduce window condensation and prevent mould from growing:

  1. Wipe down with paper towels

Before the moisture gets soaked into the walls, wipe off the condensation with paper towels and dab it across the window sill. It’s also worth wiping across blinds to stop mould from forming.

Having the windows open will allow more ventilation in the room and will reduce indoor humidity levels. It also works on helping to prevent mould growth as it reduces the amount of moisture in the air.

  1. Use a dehumidifier

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.

  1. Keep blinds and curtains away from the glass

If the blinds or curtains are touching the glass it can block the airflow and contribute to condensation getting worse.

  1. Turn the heating on in the morning

Putting the heating on for around 20 minutes in the morning can help control the humidity in the room. Open the windows first to get a healthy airflow going, then put the heating on to stop the windows from steaming up.

  1. Houseplants

It’s always worth getting houseplants like spider plants and orchids which are known to help reduce moisture in the air to make condensation more manageable. For the best results, have them placed on the windowsill.

  1. Look for window cracks

Tiny cracks in corners can be the reason for condensation being worse. If you notice any window cracks make sure to get them filled in before the cold weather kicks in.

  1. Call in the professionals

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.
