#AnglianAnswers: Why is there condensation on my windows?

By on 20th September in #AnglianAnswers, Guides

It’s time we all accepted it – ‘tis the season for window condensation. Now that summer is well and truly coming to a close, you might start to notice condensation forming on either the inside or outside of your windows. Don’t worry just yet – it’s a pretty common problem, especially at this time of year. And depending on where the condensation sits on your windows, it could be absolutely nothing to worry about.

Here, we’ll answer all your window condensation questions, including whether or not it needs addressing, and our #AnglianAnswers question of the week: why is there condensation on my windows?

External condensation

If you’ve got condensation on the exterior of your windows, you’re in luck, relatively speaking – this is generally a sign that your windows are performing well. It means that very little heat is escaping from your home through your windows, as the outer pane of your window is cooler than the outside air.

Condensation forms on your windows when the temperature outside is different to the temperature inside. If the temperature outside is lower than the temperature inside, condensation will form on the window’s external pane.

When the moisture in the air condenses onto a cold surface, this means it has reached its dew point. This tends to happen in the spring and autumn, when the dew point is generally higher than the air temperature.

You can take measures to ensure your windows don’t have external condensation, but on the whole, it’s probably not worth the time or energy, as the condensation clears up on its own and only occurs during certain times of the year.

Internal condensation

Internal condensation

Internal condensation is a whole different matter – it results when there’s excess moisture in your home, and is especially prevalent in bathrooms. It’s an issue you want to address, as it can not only damage your windows but cause mould and moisture on the inside of your home.

A simple way to eliminate excess moisture in your home is to find some appliances that help circulate the air – fans, moisture eliminators or dehumidifiers will help, as will simply opening your windows to help release all that excess water.

Condensation between the glass

Condensation between the panes of glass is a sign that your double or triple glazing is faulty. Condensation occurs in this instance as a result of a gap or hole in the sealed unit, so it needs immediate attention by an engineer. You can arrange for an Anglian engineer to visit your home via our Live Chat feature on our website.
