While windows crack or break if they’re exposed to sudden force, they can also crack for other, more subtle reasons. Known as stress cracks, these fractures are usually long and thin, running along the window. The guide below explains why these stress cracks form and how you can prevent them.

3 Causes of Stress Cracks in Your Windows

1. Inferior Installation

If you’re trying to save money, you may be tempted to choose the cheapest materials and the contractor with the lowest bid. However, these decisions can harm the long-term lifespan of your windows. If they are poorly fitted to the frame, they could receive more stress, increasing the risk of cracks and breakage.

2. Temperature Fluctuation

If you have trees outside, the shade they cast on your windows may cause issues. That’s because partial shade can create drastic temperature differentiation between sections of the window. If you’ve ever poured hot water into a cold glass, you may have experienced this effect. The sudden expansion of the glass from the heat causes cracking. In a window, these cracks will usually form along the outer edges and spread their way inwards.

3. Unexpected Impact

If any of your windows are near doors, flinging the door open could cause the doorknob to strike the window, exposing it to localized stress. Slamming them shut can create impact that leads to cracking as well. Lower them gently and add door stoppers to any doors near windows to limit the risks of stress cracking.
