Westchester County's most trusted window installers — serving Tarrytown homeowners with energy-efficient replacements, expert craftsmanship, and a lifetime warranty.
Tarrytown sits along the Hudson River in southern Westchester County, with a housing stock that reflects its history as one of the region's oldest villages. Victorian-era homes line the streets near the waterfront, while mid-century colonials and split-levels fill the neighborhoods further inland. That variety demands real expertise — not just a catalog and a crew.
Mount Vernon Window & Door serves Tarrytown homeowners throughout Westchester County. We understand the specific challenges of the local housing stock — oversized rough openings in older homes, moisture exposure from Hudson River proximity, and the demands of Northeast winters on window seals and frames. We assess the full opening, address any rot or structural issues, and install windows built to perform for 20 years or more.
Every Tarrytown 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.
Tarrytown's housing stock ranges from Victorian-era homes near the Hudson to mid-century colonials inland. We understand the unique framing and window styles of each era and install accordingly.
