The window itself
Every window in our catalog comes with the manufacturer's standard warranty, which varies by brand and tier.
See the product overviewWarranty & workmanship
Understand what covers your windows.
The manufacturer's warranty covers the product. Our workmanship guarantee covers installation. Here is how the two fit together, and which details to confirm for your specific windows.
Two kinds of coverage
The installation work
Separate from the manufacturer warranty, our installation is backed by our own workmanship guarantee.

What should I confirm for my selected window?
Review the product-specific warranty terms before buying. Confirm the covered components, duration, exclusions and any transfer conditions for your exact model.
The typical descriptions above do not provide a complete set of manufacturer terms or exclusions.
Installation workmanship guarantee
Our installation coverage describes the following work:
Seal & weatherproofing
If a window leaks due to improper installation, we fix it at no cost.
Fit & operation
If a window doesn't open, close, or lock correctly due to installation, we fix it.
Cosmetic finish
Interior and exterior trim installed by our crew is covered.
Check the complete terms.
This overview does not specify the workmanship guarantee's duration or full exclusions. Confirm those details for your project before buying; do not assume the manufacturer's warranty period also applies to installation.
