Auto Glass is part of the structure of the vehicle and is also part of the safety of the vehicle in case of an accident   Your car’s frame flexes when you hit bumps and go around corners. Add in temperature changes and that crack will grow so big we will have to replace the whole piece of auto glass. In most cases we can come to you or depending on weather we can bring the car to one of our many locations across the DFW. In some cases the attempt to repair a windshield can result in the chip to become larger and we are not responsible for the damage.
