Regardless of its' location, if the chip is a lot bigger than 3 inches than most glass company firms will tell you that you need to replace it. If the chip is smaller than that, it can usually be fixed. The important thing is that you do not get talked into replacing your windshield when it is not necessary. If you suspect that a simple front window repair job would suffice, get at least 3-5 opinions before making the final call.
Some technicians might rip you off by suggesting a brand new windshield when in fact all you need is have the crack fixed, so make sure you examine the damage. A small crack of up to six inches long can definitely be repaired. Repairing the crack or chip rather than replacing the whole windshield especially when you can help it is best because it's safe and less expensive. In addition, you can maintain the factory seal of the windshield. Windshield repair can take no more than 30 minutes of labor. If it suspiciously takes longer, be careful because the technician might be tricking you.
Allow some time of about half an hour for the windshield replacement spot to dry properly under the sunlight. Then the air bubbles should be checked. If there is any sign of them, more compounds should be placed into the spot.
Check with your insurance, because it's likely your insurance will pay for some forms of windshield chip repair. They may even waive the deductible, since repairing your windshield is so much cheaper than replacing a windshield. Should you need total windshield replacement, you may have to pay a deductible with your insurance.
Be sure to get the vehicle identification number (better known as the VIN number). On most modern vehicles the VIN number is located on the drivers side dashboard and is visible by looking through the front window, drivers side. If it looks tampered with in any way then run the other direction!
