Harlem is one of Manhattan’s richest collections of historic residential architecture. The brownstone and limestone rowhouses of Strivers’ Row, Hamilton Heights, and Mount Morris Park were built largely between the 1880s and 1910s, with tall parlor-floor windows, decorative lintels, and original wood double-hungs that have weathered well over a century of New York seasons. Sugar Hill rises with stately prewar apartment buildings overlooking the valley below. Many of these homes sit within historic districts, where window replacement must respect the original profiles and proportions. Upgrading these single-pane windows preserves the architectural character Harlem is celebrated for while delivering the comfort and efficiency a modern home demands.
We specialize in window replacement that honors Harlem’s brownstone heritage. Our custom wood and aluminum-clad windows are built to replicate original profiles, divided-light patterns, and historic sightlines that satisfy landmark district review. We offer insulated low-E glass that dramatically cuts drafts and street noise without altering the look from the sidewalk. Each project is measured precisely to fit aged masonry openings, and our crews work cleanly and respectfully inside occupied homes.
We will visit your brownstone or apartment, take precise measurements, and present window options that preserve your home’s historic character while improving comfort.
