The repair process involves the injection of special adhesives into the damaged part of the glass. The degree of success of each repair is a function of several variables. The best results are obtained when the damage is recent, the point of impact is small, the cracks around the damaged area are small, and there is no moisture or other foreign matter in the damaged area.
In some cases, the attempt to repair the windshield can result in the chip or crack becoming larger, and Auto Glass Heroes is not responsible for such damage. Auto Glass Heroes will credit half the cost of the repair towards a replacement if the repair was not successful.
