Can Cracked Window Glass Be Repaired?

Generally speaking, there are not many cases where cracked window glass can be repaired. This mainly depends on the type of crack that you have. It’s generally accepted that cracks approximately longer than an inch, double-paned glass that have holes in both panes or glass that’s broken into pieces are broken beyond repair. That means that any cracked window class smaller than that might be able to be fixed yourself. However, it’s also important to remember to repair cracked window glass as soon as possible, because small cracks can become larger in a short amount of time if they’re exposed to moisture, changes in temperature, or misuse. And while there are cracks that are small enough to be repaired yourself or by a professional, it’s important to be aware that this may only be a short-term solution depending on the damage that’s been done.

Types of Residential Window Cracks

Impact Crack

 

Just from its name, this would be what most people think of when they think about a window crack.

Stress cracks↗ start small but have potential to do a lot of damage. Usually starting at the edge of a window, a stress crack can spread across the glass over time due to temperature variances between the outside and inside the window. Continual force on the cracks through slamming the door or window shut can also cause stress cracks to appear and worsen. Finding stress cracks early is important if you want a chance a repairing the glass. Waiting too long will make it nearly impossible to repair and you'll have to replace the glass or window unit instead.

Pressure Crack

The least common type of window crack among these three is a pressure crack↗. Pressure cracks occurs when there is an intense or dramatic shift in pressure. Oftentimes, the cause of that pressure is a swift change in weather, but it also can happen if the window glass was installed incorrectly. One way to recognize a pressure crack is to look at its shape. If the window glass crack in the shape of an hourglass, you’re dealing with a pressure crack.
