If you go to a dealership, you’ll most likely pay more than at either of the other types of repair shops. Windshield repair typically takes about an hour or two to accomplish. The glass usually will cost in the area of around $115. Taken together, an average cost for a car similar to a Chevy Impala of around $300 is quite normal.
