About Mount Vernon
Window & Door
Westchester County's trusted window and door replacement specialists since 2009.
Westchester's Window & Door Experts
Mount Vernon Window & Door was founded with a simple mission: provide Westchester County homeowners with the highest quality window and door replacements at fair, transparent prices. Since 2009, we've completed over 2,500 installations throughout Mount Vernon, Yonkers, New Rochelle, White Plains, and surrounding communities.
Our team of certified installers brings decades of combined experience to every project. We're factory-trained by the manufacturers whose products we install — Andersen, Pella, Marvin, and more — ensuring every installation meets the highest standards.
We believe in doing things right the first time. That means thorough measurements before ordering, careful preparation before installation, and a detailed walkthrough after completion. We don't consider a job done until you're completely satisfied.
