Can You Repair a 10 Inch Crack in Your Windshield?

Whether it's two inches or ten inches long, a crack in your windshield can be a major cause for concern. Fortunately, many cracks can be repaired with a special resin. If you're unsure of the extent of the damage, an experienced auto glass expert can help you decide whether the crack is repairable or not. Advanced Auto Glass has years of experience installing and repairing windshields for customers in Fort Worth, Texas and the surrounding area.

Your insurance company may have certain restrictions on what damages they will pay for, but the National Windshield Repair Association has published a commercial repair standard that identifies what types of damage can be safely repaired. If you're looking to repair your windshield yourself, you can start by buying a bridge-type windshield repair kit from an auto parts store. However, it's always best to consult an auto glass professional if you're unsure about the extent of the damage. Here are some guidelines to help you determine whether you need to replace your entire windshield or just repair it.

Assessing the Damage

The first step is to assess the damage.

If the crack is shorter than three inches, it's likely that it can be repaired. However, if the crack is longer than three inches, it may be too severe for a repair and require a full replacement. Additionally, if the crack is located in the driver's line of sight, it will need to be replaced.

Repairing Your Windshield

If your windshield is repairable, you'll need to clean the area around the crack with glass cleaner and a lint-free cloth. Then, use a suction cup tool to pull out any air bubbles from the crack.

Next, inject a special resin into the crack and use a curing strip to hold it in place while it dries. Finally, use a razor blade to scrape away any excess resin.

Replacing Your Windshield

If your windshield needs to be replaced, you'll need to remove any molding or trim around the edges of the glass. Then, use a special tool to remove any remaining adhesive from the frame of your car. Finally, install your new windshield and secure it with adhesive.


Cracks in your windshield can range from minor to severe.

If you have a major crack in your front or rear windshield, consulting an auto glass professional is always recommended. With their help, you can determine whether you need to replace your entire windshield or just repair it.
