Warranty We have a lifetime warranty against leaks, loose moldings, and all workmanship. Although stress cracks are rare they will be covered under your warranty up to 30 days from date of install. If you get a windshield replaced you also get a rock chip warranty. This is good for a free rock chip repair up to 6 months from date of install. We stand behind our glass. This is the best warranty on the market. There is NO warranty on used glass.
