Warranty Coverage

Window Force windows are backed by a warranty on materials and workmanship, with coverage of up to 25 years at 100%, plus a separate 10-year non-prorated warranty on insulated glass units. Coverage is transferable to a new homeowner if the property is sold. This page explains what's covered, what isn't, and how to file a claim.

What is Covered Under the Window Force Warranty?

Warranty coverage applies to the manufactured window product — vinyl frames, sash, hardware, and insulated glass units — and is transferable to a new homeowner. Installation labour is the responsibility of the installing dealer or contractor, not Window Force. Below is a simplified overview.

Coverage Type What is Covered
Material & Workmanship Warranty Manufacturing defects in vinyl frames, sash, and hardware, tiered by year (see schedule below)

Frequently Asked Questions

How long is the Window Force window warranty?

Window Force warrants its windows against defects in material and workmanship for up to 25 years at 100% factory coverage. Coverage then steps down to 80% factory / 20% customer responsibility from years 25 to 30, and 25% factory / 75% customer responsibility beyond 30 years. The insulated glass units carry a separate 10-year non-prorated warranty.

Is the Window Force warranty transferable to a new homeowner?

Yes. The Window Force warranty is transferable if the property is sold, which adds resale value to the home and gives the new owner continued coverage for the remainder of the warranty term.

Does the Window Force warranty cover installation labour?

No. The Window Force warranty covers manufacturing defects in materials and workmanship in the window products themselves. Installation is carried out by independent dealers and contractors, who are responsible for installation workmanship and any related labour costs.

What does the glass warranty cover?

Window Force provides a 10-year non-prorated limited glass warranty. Under normal conditions, it covers material obstruction of vision caused by film formation or dust collection between the interior glass surfaces (sealed unit failure) within 10 years of the installation date.
