Windshield Crack Repair: Guide to Fixing Windshield Damage. Windshield cracks can be a hassle for any driver, impacting both the appearance and safety of a vehicle. Addressing these cracks promptly can prevent them from spreading and causing further issues. This guide will cover everything you need to know about windshield crack repair, from understanding causes and types of cracks to repair methods and tips for preventing future damage.
Understanding Windshield Cracks and Their Causes
Windshield cracks are a common issue that can result from various factors. Some common causes include:
- Temperature Fluctuations
Sudden temperature changes can cause your windshield to expand and contract, leading to stress cracks. This is especially common in extreme weather conditions. - Debris on the Road
Flying debris like rocks and gravel can hit the windshield while driving, causing chips or cracks. This is especially common in construction areas or on rural roads. - Improper Installation
If a windshield isn’t installed properly, it may be more vulnerable to cracking. Proper installation ensures the glass has the right amount of support to withstand normal stress. - Accidents or Minor Collisions
Even minor collisions can cause hairline fractures or small chips on a windshield, which may grow if left untreated.
Types of Windshield Cracks
Understanding the type of crack can help in deciding the right repair approach:
- Chip or Ding
Chips are small, circular cracks that result from debris impact. They’re generally easy to fix if caught early. - Star Break
Star breaks have a central point with small cracks radiating outwards. These can spread quickly if ignored. - Bullseye Crack
This circular crack looks similar to a bullseye target and often occurs from rounded objects impacting the windshield. - Edge Crack
Edge cracks start within two inches of the edge of the windshield and can quickly spread across the glass. - Floater Crack
These cracks appear away from the edges, often in the center. While they may not spread as fast as edge cracks, they can still grow over time. - Stress Crack
Caused by temperature or pressure changes, stress cracks lack a clear point of impact and can spread across the entire windshield.
How to Repair Windshield Cracks
1. DIY Windshield Repair Kits
DIY windshield repair kits are a popular option for minor chips and small cracks. These kits contain a resin solution that fills the crack, reducing its visibility and preventing it from spreading. Here’s how to use one:
- Clean the Area: Wipe the damaged area with glass cleaner to remove any dirt or debris.
- Apply the Resin: Using the applicator, insert resin into the crack according to the kit instructions.
- Cure the Resin: Allow the resin to dry under sunlight, or use a UV light if recommended.
2. Professional Windshield Repair
Professional repair is recommended for larger cracks or when DIY methods aren’t effective. Technicians have advanced tools and resins that ensure a stronger repair. The process typically includes:
- Vacuum Injection of Resin: The technician uses a tool to inject resin under pressure, ensuring a complete seal.
- Curing and Polishing: The resin is cured and polished to restore the windshield’s clarity.
3. Windshield Replacement
When a crack is too extensive to repair, replacement may be the only option. If the crack is longer than six inches or obstructs the driver’s view, consider replacing the windshield for safety.
