What each maker’s warranty covers
From each maker’s own document: Gentek’s window warranty (2019) and glass breakage warranty (2021), ProVia’s 2026 Endure brochure, Andersen’s 100 Series warranty (revised May 2019) and James Hardie’s HZ10 siding warranty (February 2024).
- The product, not the install
- A maker’s warranty covers what it made. Gentek’s window warranty does not cover installation, Andersen leaves out corrections for improper installation, and James Hardie leaves out siding not installed to its instructions.
- “Lifetime” has a meaning
- In Gentek’s and ProVia’s warranties, lifetime means for as long as the original buyer owns and lives in the home, not forever and not for every later owner. Finishes have shorter terms of their own.
