The size of the crack will determine the windshield repair cost. Generally speaking, the repair of small chips and cracks will cost somewhere between $20 and $60. If the size of the crack is up to a foot in length then it will cost around $50 to $60 to repair. On the other hand, if the damage is a lot worse, it will require a full replacement. Typically, a windshield replacement costs around $100-$400 but at Windshield Repair El Paso Pros we will always go for a windshield repair first and only replace the windshield when necessary.
