double glazing window repairs
If you have double-glazed windows that appears misty or cloudy and cannot be cleaned it's probably "blown". This happens when the gap between the panes of glass is widened due to the degrading of the window seals.
Replacing the gasket seals on your windows can fix this and it is far cheaper than replacing the whole double-glazed unit.
Seals
The window seal (also called the window gasket) is responsible for sealing the air between the two panes of your double-glazed windows. This stops cold drafts from entering your home, as well as stopping condensation and moisture from accumulating in the gap between the glass panes.
Over time, this seal will deteriorate because of the frequent temperature fluctuations throughout the year, which causes it to shrink and eventually pull away from the frame. Replacing the window seals is a cheap and efficient method to repair your double-glazing units.

Condensation between the two panes in windows with double glazing is a common sign of a damaged window seal. This is due to the build up of humidity in the home - this excess moisture can't escape through the glass as it cools down and condense on the surface of the window pane. This could cause windows to mist and obscure your view out of your window.
