A common issue is condensation accumulating in the gap between the two glass panes. This is a sign the window must be repaired.
1. Broken Panes
A broken double pane window is a serious issue and can expose your home to the elements. But, it's not always necessary to replace the entire window sash in order to resolve this problem. In fact, double pane windows are typically repairable with the use of a specific adhesive that is inserted into the cracks to stop the cracks from getting worse.

After this is completed and you are done, you need to take off all the glazing points and putty from the frame of your window opening. This should be done while the sash is still in place, but it can be easier to work on a flat surface, such as a table.

The window seal is an essential element of double glazing. It helps to keep your home safe and energy efficient as well as free of draft. The seal covers the entire frame's uPVC frame and creates an air-tight seal over the gas-filled space between the two panes of glass that make up the window. This is an essential element of the insulation effect the double glazing provides and any problems or failures to seals can substantially diminish this benefit.
If your seals aren't doing their job, you will see condensation between the panes. This is not only unsightly however, it could also lead to dampness and mould within the home.
