Your insurance company will most likely pay to have the chip repaired, with no charge to you. Call them. They would rather pay a small fee to repair the chip vs. pay to replace a windshield. I have had 3 or 4 chips repaired in my vehicles over the last several years. The glass company came to my work place and did the repair in the parking lot, and all I did was sign the invoice so they could charge my insurance company.
