Q: My vehicle has a chipped windshield. Should I have it repaired or should I replace the entire windshield?

A: There are several factors that determine whether a windshield should be repaired or replaced. Every chip is different. If the chip is larger than the size of a quarter or creates a crack in the windshield that is larger than a dollar bill, the windshield should be replaced. If the chip is in the driver’s line of sight (defined as the driver-side windshield-wiper sweep area), the windshield should be replaced, regardless of the size of the chip. When you repair a chipped windshield, in some instances, you may still have a small blemish on the glass, but the repair will prevent the chip from spreading.

When choosing a company to repair or replace your windshield, make certain you choose a reputable one that specializes in automotive glass. These companies are aware of all the safety issues that govern the installation of this structural component of your vehicle, and in most cases, will help you process your claim with your insurance company. You should ask if the installers are certified by the National Glass Association (NGA) and make certain they use high quality glass that meets or exceeds manufacturer standards – not all glass is created equal. There are many auto glass companies here in Arizona, but only about 20 percent are NGA certified.

Many auto glass companies offer mobile service as well. They can repair or replace your windshield at your home or office, so that you do not have to disrupt your day. In most cases, your vehicle is safe to drive within a few hours after the installation is complete, but you need to allow 24 hours cure time before washing your vehicle. If your windshield is repaired, the vehicle is safe to drive and wash within a few minutes of the repair being completed.
