# Rock Chip Repair vs Windshield Replacement: Which Do You Need?

> Repair: $50, 30 minutes, drive away immediately. Replacement: $400–900, full day, 1–24 hr adhesive cure. The line between them: chip size (≤25 mm), crack length (≤15 cm / 6 inches), edge damage, driver vision zone.

## Quick decision

| Damage | Path |
| --- | --- |
| Chip < 25 mm, single damage point | **Repair** ($50) |
| Linear crack < 15 cm (6 inches), away from edge, not in driver's vision | **Repair** ($50) |
| Crack > 15 cm | **Replacement** ($400–900) |
| Edge crack (reaches frame) | **Replacement** |
| Multiple intersecting cracks | **Replacement** |
| Damage in driver's primary line of sight | **Replacement** |
| Side or rear glass | **Replacement** |
| ADAS sensor windshield | **Replacement + recalibration** |

## Why repair when possible

- 80–95% of original glass strength restored.
- Drive away immediately (UV-cured resin).
- Alberta comprehensive insurance: $0 deductible.
- $50 vs $400–900.
- Keeps the OEM windshield (better fit, no leaks, no ADAS recalibration risk).

## When replacement is the right call

If physics says no, replacement is safer than a marginal repair:
- Edge cracks compromise structural integrity (windshield is part of the vehicle's roof crush rating).
- Driver-vision damage stays visible after repair — DOT-prohibited in many jurisdictions, including Alberta if it obstructs view.
- ADAS-equipped vehicles need calibration after replacement (additional $150–500).
