Understanding the Problem: What Causes Cracks in Building Windows?
Before we dive into fixes, let’s talk about why building windows crack in the first place.
Temperature Fluctuations
Extreme changes in weather cause glass to expand and contract. Over time, this stress can result in hairline fractures or worse.
Impact Damage
Something as simple as a bird flying into the window or kids playing with a ball can cause chips or deep cracks.
Poor Installation or Age
Older windows or improperly installed panes are much more likely to suffer stress fractures, especially in high-rise buildings.

Assessing the Severity of the Crack
Before you decide on a repair method, check if the crack is superficial or structural. If it spans the whole pane or threatens the frame, it might be time to upgrade.
Temporary Fixes for Immediate Safety
Use duct tape or clear packing tape to hold the crack in place until you apply a more permanent solution. This helps avoid further spread and reduces injury risk.
