A tiny crack in your windshield might seem harmless—but it can turn into a major problem if left unchecked. Beyond obstructing your view, it could pose safety risks and even make your vehicle illegal to drive in some states.
To keep yourself safe and avoid costly repairs down the road, here’s your complete guide to identifying, repairing, or replacing a cracked windshield.
Understanding Windshield Crack Types
Not all cracks are created equal. Knowing which kind you have will help you decide whether repair is possible—or if replacement is the only option.
-
Bullseye: Circular damage, usually fixable if under 1 inch.
-
Star Crack: Has radiating lines; more likely to spread.
-
Combination Crack: Includes multiple types, requiring professional evaluation.
-
Edge Crack: Starts at the windshield’s edge—usually harder to repair.
-
Stress Crack: Often occurs without impact, due to temperature or pressure changes.
📌 Pro Tip: If you plan to sell your vehicle, even minor cracks should be addressed to avoid affecting its value.
DIY Repair Kits vs. Professional Help
DIY Repair Kits
These are widely available and typically include resin, applicators, and curing strips. They’re ideal for:
-
Small chips or cracks
-
Shallow surface damage
However, incorrect application can make the damage worse or cause an incomplete repair.
Professional Services
Auto glass experts—like those at Van Isle Glass—can assess the situation and repair or replace the windshield using high-grade materials and technology. A professional repair is faster, stronger, and more reliable in the long term.
When Can a Crack Be Repaired?
Several factors influence whether your windshield can be repaired:
-
Size & Depth: Cracks under 6 inches or chips smaller than a quarter are generally repairable.
-
Location: Cracks near the edges or in your direct line of sight often require replacement.
-
Age of Damage: Older cracks may contain dirt or moisture, making repair less effective.
-
Weather Exposure: Heat and cold can expand cracks rapidly.
How a Windshield Crack Is Repaired
The repair process is quick and straightforward:
-
Clean the area thoroughly to remove debris.
-
Inject resin into the crack under vacuum pressure.
-
Cure the resin with UV light to harden it.
-
Polish the surface for clarity and smoothness.
⏱️ Time needed: Under an hour.
💲 Cost: Typically $50–$150.
Even though the crack may still be faintly visible, this process restores the glass’s strength and prevents further spreading.
When Replacement Is the Only Option
Sometimes, repair just isn’t enough. You’ll likely need a full windshield replacement if:
-
The crack is over 6 inches
-
It’s located at the edge or obstructs your view
-
There are multiple chips or cracks close together
Replacement takes longer—usually a few hours—and can cost more, especially for high-tech windshields with sensors or HUDs.
Cost Breakdown & Insurance Tips
-
Repairs: $50–$150
-
Replacements: $200–$1,000+ (varies by make and model)
Check your insurance policy—many cover windshield repair or replacement with no deductible. Some auto glass shops even handle the insurance paperwork for you.
Final Thoughts
A cracked windshield isn’t just a cosmetic issue—it’s a safety concern. Whether you choose a DIY solution or turn to professionals, quick action can save you time, money, and headaches down the road.
👉 When in doubt, get it checked. It’s your safety—don’t compromise.
