Frequently Asked Questions
What is a Windshield Crack Repair?
A windshield crack repair is a process of filling and sealing a damaged area on your windshield, typically caused by a rock chip, bullseye, or small crack. The goal of repair is to prevent the damage from spreading and maintain the structural integrity of the windshield. The process involves cleaning the area, applying a specialized resin, and then curing it with a UV light or air pressure.
How Does a Windshield Crack Repair Work?
A windshield crack repair works by injecting a clear resin into the damaged area, filling the crack or chip. The resin is then cured using a UV light or air pressure, which helps to seal the area and prevent further damage. The resin is designed to match the color and clarity of the surrounding windshield glass, making it nearly invisible. The repair process typically takes 30 minutes to an hour, depending on the size and location of the damage.
Why Should I Repair a Windshield Crack Instead of Replacing the Entire Windshield?
Repairing a windshield crack is often a more cost-effective and convenient option than replacing the entire windshield. A windshield replacement can cost anywhere from $300 to $1,500 or more, depending on the type of vehicle and the complexity of the repair. In contrast, a windshield crack repair typically costs between $50 to $200, making it a more budget-friendly option. Additionally, repairing a crack can help to prevent further damage and extend the life of the windshield.
How Do I Start a Windshield Crack Repair?
To start a windshield crack repair, you’ll need to purchase a windshield crack repair kit, which typically includes the necessary resin, tools, and instructions.

What if the Windshield Crack is Too Large or Complex to Repair?
Not all windshield cracks can be repaired. If the crack is too large, complex, or located in a critical area of the windshield, it may be necessary to replace the entire windshield. A professional auto glass repair technician can assess the damage and determine the best course of action. In some cases, a windshield crack repair may not be possible, and a replacement may be the only option.
Which is Better: Windshield Crack Repair or Replacement?
The choice between windshield crack repair and replacement depends on the size and location of the damage, as well as your personal preferences and budget. If the crack is small and located in a non-critical area of the windshield, repair may be the best option. However, if the crack is large or complex, or if you’re looking for a more permanent solution, replacement may be the better choice. It’s always recommended to consult with a professional auto glass repair technician to determine the best course of action.
How Much Does a Windshield Crack Repair Cost?
The cost of a windshield crack repair can vary depending on the size and location of the damage, as well as the type of vehicle. On average, a windshield crack repair can cost between $50 to $200.
