Rock chip repair is not a cosmetic repair; you may still see where the chip is located once the repair is complete. The sole purpose of a professional windshield repair is to restore the structural integrity of the glass and prevent it from spreading. Since we are working with glass that is already broken, during the repair, there is always a possibility that as the technician is pushing the resin (glue) into the chip that the chip could spread. If that should happen, we will not charge you or your insurance for the attempt but we cannot guarantee the windshield before and after the repair (NO WARRANTY). Price will be 75$ for the first one and 35$ for any additional chip.
