What Types of Car Window Cracks Can Be Repaired?

Types of Car Window Cracks
1. Star Break (Short Radial Cracks)
A star break is characterized by short radial cracks that extend outward from the point of impact. These cracks typically form a star-like pattern and are caused by a circular object striking the glass with significant force.
2. Bulls-Eye (Circular Damage)
A bulls-eye is a circular crack caused by a circular object hitting the glass. The damage is typically centered around the point of impact and can be repaired if it’s not too severe.
3. Partial Bulls-Eye (Half Moon)
Also known as a half moon, a partial bulls-eye is similar to a bulls-eye but the damage is not completely circular. It’s caused by a circular object striking the glass at an angle.
4. Crack Chip (Single Crack)
A crack chip is a single crack that measures approximately the size of a quarter. It’s caused by a small object hitting the glass with enough force to create a crack.
5. Ding (Same as Crack Chip)
A ding is the same as a crack chip, a single crack about the size of a quarter caused by a small object striking the glass.
6. Pit (Chipped Glass)
A pit is a small chip in the glass caused by a small object hitting the surface. While a pit may not seem like a significant problem, it can lead to further cracking if left untreated.
Repairing Car Window Cracks
Not all car window cracks can be repaired, and it’s important to understand the limitations of glass repair. In general, cracks that are less than 12 inches long and chips that are smaller than a quarter can be repaired using a resin injection method.

Resin Injection Repair

Resin injection is the most common method used by professionals to repair small cracks and chips. In this process, a special resin is injected into the damaged area, filling the crack or chip and restoring the structural integrity of the glass.

Crack Filling Techniques

For larger cracks, professionals may use a variety of crack filling techniques to mend the damage. These methods can include using traditional adhesive compounds or more advanced vacuum processes, depending on the size and location of the crack.

When Replacement is Necessary

In some cases, the damage to the car window is too severe to be repaired, and replacement is necessary. If a crack is longer than 12 inches or a chip is larger than a quarter, the window should be replaced. Additionally, if a crack or chip has been repaired before and continues to grow, or if the damage is not clean and has branching cracks, replacement is the best option.
Windshield replacement is a job best left to professionals, as it involves removing the old windshield and installing a new one. When choosing a replacement, it’s important to consider factors such as quality, fit, and compatibility, and to ensure that the new glass meets safety standards.
