🔒 Our Lifetime Warranty
At Glass Masters Auto Glass, we back every repair and replacement with a comprehensive lifetime warranty. From chips to calibration, you’re protected — because peace of mind is part of our promise.
🛠️ Windshield Repair Warranty
We use advanced resin-injection techniques to fill chips and small cracks (under 3") immediately, restoring structural integrity and optical clarity. If any repaired area expands or re-cracks during your ownership of the vehicle, we will credit the full cost of that repair toward a complete windshield replacement.
⚠️ Repair Disclaimer
Windshield repair is designed to halt damage propagation, not to erase its appearance. You acknowledge that:
- The glass was already broken; further cracking may occur before, during, or after repair.
- Repaired areas may remain visible under direct sunlight or interior lighting.
- Vibration, temperature shifts, or impacts may exacerbate existing damage at any time.
🪟 Windshield Replacement Warranty
All glass replaced by Glass Masters is OE-quality, laminated to factory specifications, and installed using premium urethane. Your windshield is warranted against defects in materials, stress cracks, seal failure, and manufacturing errors.
📄 Parts Warranty Disclaimer
This warranty excludes damage from subsequent rock chips, road debris, vandalism, or any external impact occurring after installation is complete.
🔧 Labor Warranty
Our technicians are AGSC-certified and follow strict installation protocols. We guarantee our workmanship for the life of your vehicle. Should any aspect of our installation fail due to labor, we will remediate it promptly at no charge.
📄 Labor Warranty Disclaimer
Covers defects arising directly from labor performed by Glass Masters technicians. Does not cover damage from misuse, collisions, unauthorized alterations, or subsequent impacts. Upon valid claim, we will inspect and correct the issue at no cost.
💧 Leak Warranty
Should you discover any water infiltration after glass replacement, contact us immediately. We will perform a comprehensive leak-detection test—inspecting seals, sunroofs, antennas, and racks—to pinpoint the source, reseal the glass (successful in 90% of cases), or, if necessary, remove and reinstall with new urethane at no charge.
💧 Leak Warranty Disclaimer
Excludes leaks caused by customer alterations, accidents, or external damage. If you are ever dissatisfied with our work or service, notify us promptly so we may address and resolve the issue—your satisfaction is our highest priority.
📡 LDWS Calibration Warranty
Our calibration process uses the Opti-Aim laser-guided system and manufacturer's software to restore ADAS features—Forward Collision Alert and Lane Departure Warning—to factory tolerances. We guarantee proper operation post-calibration.
📄 Calibration Disclaimer
Valid only if calibration is performed by Glass Masters after windshield installation. Void if the customer declines calibration, fails to remit payment, or if the invoice is unsigned by the insured policyholder. Ensuring proper ADAS function is critical to your safety.
