Key Takeaways for Homeowners
- Manufacturer product warranties and contractor workmanship warranties are two separate legal protections.
- Look for non-prorated glass seal failure coverage lasting at least 20 to 25 years.
- Ensure installation covers perimeter flashing, air-seal foam, and water infiltration for at least 5 to 10 years.
- Transferable warranties add tangible value when selling your home to prospective buyers.
## Navigating Fenestration Warranty Terms
Window marketing often touts "Lifetime Warranties," but the legal definition of "lifetime" varies dramatically between manufacturers. Understanding warranty terms protects you from unexpected out-of-pocket repair bills.
### Key Warranty Components to Check:
1. **Insulated Glass Seal Failure:** Covers cloudy condensation or fogging between panes. Ensure it is non-prorated (does not decrease in value over time).
2. **Vinyl Frame Warping & Color Retention:** Covers cracking, peeling, chalking, or distortion under normal solar exposure.
3. **Operating Hardware:** Covers locks, balances, tilt latches, and casement crank operators.
4. **Accidental Glass Breakage:** Premium warranties include complimentary glass replacement if a lawnmower stone or ball cracks a pane.
5. **Contractor Workmanship Warranty:** Installation and workmanship terms are agreed directly with the independent contractor and should appear in the written contract.
