Car windshields today have been built for safety more than ever before. A typical windshield is made of two glass panels with a layer of plastic laminated in between. They are largely impact-proof, except in the most severe collisions. This does not mean, however, that they can last forever. A windshield that has seen some wear and tear could crack from even a tiny impact, such as when a small rock hits it. When this happens, you can get your windshield either repaired or replaced.
If the crack is less than 12 inches in length, or in the case of a chip, if it is just the size of a quarter or smaller, the windshield may be repaired. Anything bigger might require a replacement. A Redmond auto glass repair and replacement company can help you determine what to do, so you should call one immediately.
