How To Stop A Windshield Crack From Spreading

A windshield crack can spread quickly if you don't take action. Temperature changes, road vibrations, and even slamming your car door can cause a small crack to grow into a much larger problem. Here are several ways to slow down or stop a windshield crack from spreading until you can get it professionally repaired.

1. Apply Clear Tape Or A Windshield Repair Kit

The simplest temporary fix is to apply a piece of clear packing tape over the crack on the outside of the windshield. This keeps moisture, dirt, and debris out of the crack, which can slow its growth. You can also purchase a windshield repair kit from an auto parts store. These kits include a clear resin that you can inject into the crack to stabilize it temporarily.

Keep in mind that both of these are temporary fixes. They can slow a windshield crack from spreading, but they are not a substitute for professional windshield crack repair.

2. Avoid Extreme Temperature Changes

Temperature changes are one of the biggest reasons windshield cracks spread. When glass heats up, it expands. When it cools down, it contracts. This expansion and contraction puts stress on the crack and causes it to grow. To slow a windshield crack from spreading:

Don't blast your defroster on high when it's cold
Don't pour hot water on a frozen windshield
Park in a garage or shaded area when possible
Avoid parking in direct sunlight for extended periods

3. Avoid Rough Roads

Vibrations from rough roads, speed bumps, and potholes can cause a windshield crack to spread. If your windshield has a crack, try to drive on smooth roads when possible. Avoid slamming your car doors, and drive gently over bumps and uneven surfaces.

4. Don't Use Your Car Wash

The high-pressure water from a car wash can force water into the crack and cause it to spread. Avoid going through automatic car washes until your windshield crack has been repaired. If you need to clean your car, use a gentle hand wash and avoid spraying water directly on the crack.

5. Get It Repaired As Soon As Possible

The best way to stop a windshield crack from spreading is to get it repaired by a professional. The longer you wait, the more likely the crack is to grow, and a larger crack may require a full windshield replacement instead of a simple repair.
