Solutions for misty or foggy windows

Whether you are moving into a new home or if you are having problems with your double glazed windows or doors, you may find you have double glazing failure.

Double glazing is designed to last around 20 years, sometimes longer, but maintaining them is dependent on ensuring they were well installed and have had proper ongoing maintenance.

If you think your double glazing is starting to have problems, such as becoming misty or foggy, don't worry; you probably don't need to replace your whole double glazing. Replacing the sealed units could be a quicker and cheaper solution.

Some common signs that your double glazing units could be failing, include:

  • Misty or foggy windows
  • Condensation
  • Leaks
  • Scratches, cracks or chips
  • Draughts

How do sealed units become misty?

When mist or fog appears between the two glass panes of your double glazed window, you know you've got a problem. Any sign of condensation or misting between the two glass panes will usually require a full sealed unit replacement.

If you put it off, the window will become more misty and full of moisture; the window will not only look unsightly, but you will experience heat loss. A replacement sealed double glazed unit will keep the cold out, keep the heat in your home, and your bills down!
