Steamed up windows are where condensation forms in between your double-glazing windows. If you can’t clean off your window then the condensation will be in between the glass.

How they steam up?

Windows steam up by warm, moist air coming into contact with the cold surface of your windows, when they come into contact it creates condensation. Now, for the most part, this is perfectly normal when it can be wiped away however, the issue arises when it’s inside of your window. If the condensation is inside your glass then it means you have a broken seal around the panes of glass which needs to be replaced.

Effects of steamed up windows

Steamed up windows aren’t to be treat lightly as they can have detrimental effects on your glass. The glass inside your window could potentially crack or shatter which could cost you more money to repair. It is important that you get your windows inspected as soon as possible. At National Glass we offer a free, no obligation quote so if you’re ever unsure be sure to fill one out. We also offer free home visits so we can get a good look at what the issue is.


If you catch a broken seal early on it is possible for us to repair the seal without having to actually replace the glass. However, if your windows have already begun to steam up then we’ll have to replace the glass as there’s already moisture in-between the panes of glass. What most people don’t realise is that we don’t have to replace the entire window just the glass that’s inside of it which saves you £100s.
