Home windows in Illinois are subject to extreme temperature fluctuations throughout the day. This is particularly true in late fall and early spring when daytime temperatures can be much higher than the nighttime low. This can lead to a structural failure in the window pane itself, causing foggy windows, and ultimately, a foggy window pane repair.
The cause of the foggy window pane is the failure of the air-tight window seal between the double panes or triple panes of the glass window itself. While most window pane seals last for many years, the constant expansion and contraction of the window can lead to seal failure over time.
