Westchester County's most trusted window installers — serving Yonkers homeowners with energy-efficient replacements, expert craftsmanship, and a lifetime warranty.
Yonkers is Westchester County's largest city — and one of its most diverse in terms of housing. From the century-old brownstones and colonials in Park Hill and Nodine Hill to the postwar ranches and split-levels in Dunwoodie and Crestwood, Yonkers homes span nearly every era of American residential construction. That variety means window replacement here requires real expertise, not just a catalog and a crew.
Mount Vernon Window & Door has been serving Yonkers homeowners throughout Westchester County. We understand the specific challenges of the local housing stock — oversized rough openings in older homes, aluminum-clad frames that have oxidized over decades, and the particular demands of Northeast winters on window seals and frames. We don't just swap glass; we assess the full opening, address any rot or structural issues, and install windows that will perform for 20 years or more.
Every Yonkers installation includes a free in-home estimate, written quote with no hidden fees, and a lifetime warranty on both the window and the installation labor. We pull all required permits, handle the inspection, and clean up completely before we leave.
From the Victorian-era colonials in Park Hill to the mid-century ranches in Crestwood, we've worked on every window style Yonkers has to offer. We know what fits, what works, and what lasts.
Yonkers winters are no joke. Our ENERGY STAR® certified windows with Low-E glass and argon fill cut heating costs by up to 30% — a real difference on your Con Edison bill.
