Warranty

A highly respected window and door manufacturer for more than 30 years, Marlboro is proud to stand behind its products with a lifetime warranty on vinyl, aluminum, insulated glass units and hardware. And compared to the warranties offered by many window and door manufacturers, our warranty is transferable from the original end-use purchaser to future owners.

Our transferable lifetime warranty applies to defects in materials and workmanship under normal use. Because improper installation and maintenance, unauthorized repairs or alterations, misuse, neglect and other factors can void your warranty, be sure to read our maintenance instructions and warranty exclusions.

Vinyl Transferable Lifetime Warranty

We guarantee that the vinyl in your windows and doors will not warp, blister, flake, crack, peel, rot, rust, pit or discolour, due to defects in materials and workmanship. Read more.

Insulated Glass Unit Transferable Lifetime Warranty

We will replace your insulated glass unit (two panes of glass in a hermetically sealed unit) if condensation occurs as a result of a breach of the seal due to defects in materials and workmanship. This provision applies under normal use. Installation is not included. Read more.

Hardware Transferable Lifetime Warranty

We guarantee that hardware on your windows and doors, including locks, lifts, handles, closures and tracks, will be free from defects in material and workmanship. Read more.

Aluminum Transferable Lifetime Limited Warranty

We guarantee that the aluminum frames and sash members in your windows and doors will not corrode, rot, rust, crack, warp or pit, due to defects in materials and workmanship, for 10 years from the date of manufacture. We also guarantee they won’t blister, peel, check, craze or crack, due to paint defects, for six months. Read more.
