For more than 35 years, Marlboro Window has set the standard for reliability, and our promise is as transparent as our windows: if you ever have any manufacturing – related problems with any Marlboro windows, we’ll fix it or replace it – hassle free
Marlboro is proud to stand behind its products and installation with a LIFETIME warranty on vinyl, aluminum, insulated glass units and hardware. Unlike the warranties offered by many window and door manufacturers, Marlboro’s warranty is transferable from the original end-user purchaser to future owners.
Our transferable LIFETIME warranty applies to defects in materials and workmanship under normal use
We guarantee that the vinyl in your windows will not warp, blister, crack, rot, rust or pit due to defects in materials and workmanship.
We guarantee that the aluminum frames and sash members in your windows will not corrode, rot, rust, crack, warp or pit, due to defects in materials and workmanship.
We guarantee that the paint applied to your windows will not warp, blister, flake, crack, peel, rot, rust, or pit due to defects in materials and workmanship.
We will replace your insulated glass units if condensation or breakage occurs as a result of a breach of seal due to defects in materials and workmanship. This provision applies under normal use.
We guarantee that hardware on your windows, including locks, lifts, handles, closures and tracks, will be free from defects in material and workmanship.
We guarantee that your windows supplied and installed by Marlboro are free from operational defects.
Improper maintenance, unauthorized repairs or alterations, misuse, neglect and other factors can void your warranty.
This warranty is effective for windows supplied and installed by Marlboro for non-commercial use after January 2012
