How to stop condensation on windows

Are the windows in your property covered in moisture every morning? This is likely caused by excessive moist air caused by everyday activities. This then condenses on the cold glass, forming condensation.

Allowing condensation to collect on your windows can quickly lead to mould growth and damage around the window frame. Therefore it is crucial to remove excess moisture from your windows and figure out why it is collecting there in the first place.

This page will detail how to clear your damp windows with regular cleaning and ventilation techniques, enhancing insulation, improving ventilation and even upgrading your windows. We hope the expert advice below will help you address condensation on windows in your home effectively.

Usually the answer is no. If condensation is present on your windows it would suggest they are functioning correctly in terms of being energy efficient. However you have to open them or the trickle vents on them to allow air to pass through. The problem is excess moisture inside the property.

On a lot of solid surfaces like windows, mirrors or tiles, condensation can be wiped away safely, however any adjacent timber, plaster or decorative wallpaper will absorb this excess moisture leading to damp patches, mould and timber decay. This means potential damage to window frames and sills and other fixtures and fittings.

In the long term preventing the source of the condensation problem is the best course of action.

To prevent condensation on windows, ventilation is key. Any of the ventilation solutions below will prevent condensation on windows:

• Open windows whenever possible
• Run heating on a constant low setting
• Use extractor fans or dehumidifiers to reduce moisture in the air
• Improve insulation in your property to achieve warmer walls
• Check windows for damaged seals
• Consider thinner curtains or drapes
• Keep doors open at night or consider door undercut ventilation

Double glazing has many advantages over single glazing when it comes to improving the thermal properties of your home but excessive humidity can lead to condensation on double glazed windows when moist indoor air contacts the cooler glass surface.

Condensation can also occur inside the double glazing if its sealant fails, allowing warm air to enter the gap between glass panes. If you notice this you should inspect window seals for damage to prevent water ingress and avoid frame damage.

Proper ventilation is crucial in kitchens and bathrooms to prevent excess moisture accumulation. Condensation in bedrooms should not be ignored, as it may indicate window frame damage or promote mould growth on soft furnishings.
