“Lifetime warranty” sounds great until you read the fine print — here is what actually matters in a Quebec window warranty.
Three Warranty Components You Need
- Frame and sash — usually 20+ years on quality UPVC
- Insulated glass seal — minimum 20 years
- Hardware (hinges, locks, cranks) — typically 5–10 years
Transferability and Resale
Transferable warranties survive if you sell your home — a real selling point. Some only cover the original buyer, which limits resale value.
Common Exclusions
Watch for exclusions like “commercial use”, “coastal exposure”, and improper installation. Always have a certified installer do the work.
Registration Matters
Most warranties require registration within 30–90 days of installation. Save the paperwork.
Frequently Asked Questions
What voids most warranties?
DIY installation, painting frames, and using harsh cleaners.
Is lifetime warranty really lifetime?
Often defined as 25 years — read the definition.
Are there pro-rated warranties?
Yes — coverage decreases over time. Look for non-pro-rated coverage on the glass seal.
