Rock Chip Repair vs. Full Windshield Replacement: How to Decide

You can usually repair a rock chip if it is smaller than a quarter, not in the driver's direct line of sight, and not touching the edge of the windshield. If the damage is a crack longer than 6 inches or deep enough to penetrate both layers of glass, a full windshield replacement is required.

When Rock Chip Repair is the Best Option

Rock chip repair is a fast, cost-effective process that takes about 30 minutes. A technician injects a specialized structural resin into the chip under a vacuum seal, then cures it with UV light. You should opt for a repair if:

• The chip is smaller than a US quarter (about 1 inch in diameter).
• There are three or fewer chips on the entire windshield.
• The damage is not in the driver's primary viewing area (which could cause a slight distortion even after repair).
• The damage is not at the very edge of the windshield.

Urgency is key: In the Texas heat, the extreme temperature difference between the hot outside air and your cold A/C inside causes thermal stress. A small, repairable chip can easily spider-web into a massive crack in a single afternoon.

When You Need a Full Windshield Replacement

Repair resin can only do so much. The structural integrity of your windshield is vital to your safety in a rollover accident. You must get a full replacement if:

• The crack is longer than a dollar bill (about 6 inches).
• The crack reaches the outer edge of the glass (this compromises the structural seal).
• The damage is deep enough that you can feel it on the inside of the windshield.
• The damage is directly in front of the driver's steering wheel.

The Cost Difference

Rock chip repair is incredibly affordable and is often 100% covered by insurance with no deductible—meaning it costs you $0. Full replacements are also covered by comprehensive insurance, but you will have to pay your deductible if you have one.
