How to Prevent Windshield Cracks From Spreading

by Contributor

If your vehicle's windshield is cracked, you have only two options. You either can pay to have the entire windshield replaced or have the crack repaired. Repairing windshield cracks can stop the cracks from spreading and cut out the high cost of replacing the entire windshield. Learn how to prevent windshield cracks from spreading with these steps.

Step 1

Assess the crack to determine if it can be repaired or if the entire windshield should be replaced. If the crack is older than 30 days, wider than 1/8 of an inch or longer than 12 inches, have the windshield replaced.

Step 2

Take your vehicle to a glass repair shop. A good shop services vehicles with the best glass available and can repair the crack and chipped area. The crack will remain visible but much less noticeable and the windshiled won't crack any further.

Step 3

Have the shop give you an estimate. Compare this estimate with at least one other glass repair shop's. Compare the costs of the repair with the cost of having the windshield replaced. Most windshields cost more than a repair, but comparing them lets you know the difference.

Call your insurance company to see if the repair is covered under your insurance policy. Some insurance policies pay for the repair or replacement of the windshield. Other companies don't cover either, and you must pay the deductible or go out-of-pocket for the entire repair.


  • If you notice a crack in your windshield, bring it to a repair shop as soon as possible. Often the crack cannot be fixed if it is over 30 days old.


  • Don't wash your car or park it in direct sunlight if you notice a crack. Both of these can cause the crack to expand, making it impossible to repair.
