The federal regulations of the United States typically allow auto glass technicians to repair a chip with a diameter of around an inch or less, and a crack no more than three inches long. If the size of the crack is larger than that of a dollar bill, repair is not an option. This is why size and depth are so important when it comes to determining whether a repair is possible or not. Even if the windshield crack appears to be repairable, it is still worth consulting an auto glass repair and replacement company to find the best solution for your problem.
The auto glass technician will assess the situation and decide if the crack can be repaired or not. If you spot one or more small cracks in your front or rear windshield, you should take your vehicle to an auto glass repair shop or contact a mobile windshield repair service. If the crack is major, you should fix it as soon as possible with the help of an auto glass repair company. Ignoring a major crack can lead to further damage due to the pressure placed on the car's glass.
If you are unsure of the extent of the damage, an experienced auto glass expert can help you decide whether the crack is repairable or not.
