Does a Cracked Window Need to Be Replaced?

Windows are not just for looking through. Though it may seem that visibility is the sole purpose of your car’s windows, they are also for structural support. Every piece of glass on your car -- the windshield, rear window, and all of the side windows -- provides stability, rigidity, prevents body roll, and supports the roof.

There isn’t a lot that can go wrong with window glass. One of the only things possible is a cracked window. Window cracks can happen from a number of sources, including:

  • Impact from a stone or rock when traveling on the highway
  • Vandalism
  • Stress crack from manufacturing defects
  • Cracking from weather changes
  • Window regulator or track malfunction

Seeing as windows are a structural support in your vehicle’s design, a cracked window needs to be replaced as soon as possible. Windows in your vehicle are made of tempered glass that is designed to shatter into tiny pieces in a collision. This prevents injuries from sharp shards of glass.

However, because windows are designed to shatter in such a way, a cracked window can experience complete failure very easily. While a cracked window can stay just that way for extended periods of time, it could also take only one more operation of the window, turning on the heat or rear window defogger to cause it to shatter.

A small crack in a windshield typically can be repaired by some automotive glass shops, though repairs aren’t guaranteed to last, and some repairs are not possible. Side windows that are cracked cannot be repaired. If you have experienced a cracked window from any source, including the ones listed, have the affected window inspected or replaced.

Jason came to my office and worked while it was freezing to help alleviate my issue of my window not closing. Then reassured me that he'll return at a later date to install parts needed. He never complained once and paid attention to details. I will use Jason again in the future.
