Preventing Cracks in a Windshield

How to prevent cracks in a windshield from spreading. If your vehicle’s windshield is cracked, you only have two options. You can pay to change your whole windshield or repair the cracks. Repairing cracks in a windshield can prevent cracks from spreading and decrease the high cost of replacing the entire windshield. Learn how to prevent cracks in a windshield from spreading with these steps.


  1. Examine the cracks to determine if it can be repaired or if the entire windshield should be changed. If cracks are older than 30 days, wider than 1/8 of an inch or longer than 12 inches, the entire windshield changes.
  2. Take your vehicle to a glass repair shop. A good shop will arrange vehicles with the best glass available and can repair the cracked or chopped area. The crack will remain visible but much less noticeable and the windshield will not crack anymore.
  3. Make the store give you a quote. Compare this quote with that of at least one more glassware. Compare repair costs with the cost of replacing the entire windshield. Most windshields cost more than a repair but comparing them will let you know the difference.
  4. Call your insurance company to see if the repair is covered in your insurance policy. Some insurance policies pay for the repair or replacement of the windshield. Other companies do not cover any, and you must pay the deductible or pay out of pocket for all repair.

Tips & Warnings

  • If you notice a crack in your windshield, take it to a glass shop as soon as possible. Often cracks cannot be fixed without being greater than 30 days.
  • Do not wash your car or stations in direct sunlight if you notice a crack. Both things cause the crack to expand, making it impossible to repair.
