When properly installed, windows are durable and protect your home from drafts. However, there are some instances when you may require window repairs to address cracks on the glass. This type of damage comes in many forms, and understanding these may help you avoid them. Here’s more information to help you keep your fixtures in top shape.

What Are the Types of Glass Damage?

1. Stress Cracks

A stress crack starts out on the edge of the window and expands across the glass. This can happen when there are temperature fluctuations within the glass, which is common during fires. You might also face this if you close the window too hard.

Fire prevention will help you avoid these cracks. To stay safe, always keep an extinguisher around the house. You should also avoid slamming the window or letting it fall down on its own. 

2. Impact Breaks

Impact breaks are caused by an object hitting the glass. This projectile could be a bird, ball, or hail, for example. These cracks radiate from where the object hit, expanding outward.

You generally can’t get a window repair to fix these and will need a replacement. You can avoid this issue by making sure your children play several dozen feet away from the house.

3. Pressure Cracks

This is a more uncommon type of damage. It occurs in dual-pane windows or insulated glass, and tends to curve in an hourglass shape. It’s caused by a weather-related sudden pressure change or improper installation. Since insulated windows can’t be repaired, a pressure crack generally requires a full replacement.

To avoid this issue, always hire professionals to install your fixtures.
