Other Problems That May Need Double Glazed Windows Repair

A common and major problem that will cause double glazed windows to need repair is what professionals refer to as “break down.” “Break down” occurs when the seal on the perimeter of the sealed window unit has begun to leak, allowing moisture to accumulate between the two window panes. This is a problem that might be difficult to notice at first, but over time, allows water to fill up the inner space, sometimes to a level of a few inches. This problem may often be difficult to spot in the early stages other than the fading or discolouration present if the glass is coloured.

Another problem that can occur and require repair, is the window panes in the double glazed units exploding. They are not actually exploding, but imploding. This occurs as a result of weak or scratched glass used in the manufacture of the window, conditions present during the manufacture of the window, or thermal stress after the window was installed.The combination of indoor heat and outdoor cold temperatures place a great deal of stress on the window. An “oily” condition, called “Brewster’s Fingers,” might also occur and cause repair of the double glazed window. Although this happens rarely, the only way to “repair” this condition is by replacing the sealed unit. It is caused by the high quality of glass sometimes used today compared to the older versions of sheet glass.
