Some windshield chips, stars, and cracks can be repaired while others will require replacement of your entire windshield. Generally, chips, stars, and cracks up to 8 inches can be repaired. The goal with windshield repair is to stop the crack from spreading to prevent the need to replace the entire windshield. This is why it is important to get them repaired immediately before they spread requiring replacement of the entire windshield. The clear resin we apply for glass repair takes 20-30 minutes to cure and then you can drive your automobile immediately. You will still be able to see the chip, star, or crack in your windshield but it will be significantly less noticeable.
