Your windshield damage may require a full replacement or may be fixed by a simple repair.
If the windshield damage is more severe than a minor chip or crack, or if the crack is in the driver's line of vision, then most likely your windshield will require replacement. Cracks or holes that go all the way through the glass and cracks that are longer than a credit card usually indicate a replacement is warranted.
Windshield repair is a convenient, cost effective way to fix minor chips and cracks in your car's front windshield. If your windshield damage is not directly in the driver's line of vision, chances are good that your auto glass can be repaired. Another good way for you to assess the damage is to see if the crack is NOT longer than your credit card, then it can usually be repaired.
