Your windshield is an important part of your car, and a cracked windshield can be a serious safety issue. If you have a crack in your windshield, you may be wondering if you should repair or replace it. Here are some things to consider from an auto glass repair specialist when making your decision.

The Size of the Windshield Crack or Chip

When your windshield is damaged, you have to decide whether to have it repaired or replaced. The size of the damage will help you make that decision.

If the crack or chip in your windshield is less than three inches long, you can have it repaired. The repair will fill the crack or chip with a resin that will prevent it from spreading.

If the crack or chip in your windshield is more than three inches long, you will need to have it replaced. A crack that is more than three inches long is too big to be repaired and if it is not replaced, it will continue to spread.

The Depth of Windshield Crack or Chip

This is closely related to the size of the damage, but also to how far into the windshield the damage extends. An exterior layer of glass, a plastic interlayer, and an interior layer of glass make up a windshield, which is referred to as sandwich glass. The damage is too severe to be repaired with a windshield if it extends through both the outer and inner layers of glass.

The Location of the Windshield Crack or Chip

If you have a small crack or chip in your windshield, it may be possible to have it repaired rather than replaced. However, the location of the crack or chip can play a role in whether it can be repaired or not. 

If the crack or chip is in the driver’s field of view, it will likely need to be replaced. This is because even a small crack or chip can obstruct the driver’s view and be a safety hazard. Otherwise, it can usually be repaired. This is because the repair will not obstruct the driver’s view and will not be a safety hazard.

Windshield Repair vs. Replacement

Windshield replacement is often the best option when the windshield is cracked, chipped, or shattered. However, there are times when windshield repair may be a better option. Here are some pros and cons of each option to help you decide what is best for your situation.
