Washington Heights is defined by its grand prewar apartment buildings, built across the hills of Upper Manhattan largely between the 1910s and 1940s. Six-story Art Deco and Tudor-influenced buildings line streets like Fort Washington Avenue and Cabrini Boulevard, many with handsome lobbies, courtyards, and rows of original wood double-hung windows. Perched on Manhattan’s high ground near the Hudson and Fort Tryon Park, these homes enjoy sweeping views and strong exposure to wind and weather. Most still have their original single-pane windows — beautiful but drafty and inefficient. Many buildings are now co-ops with their own appearance standards. Premium replacements deliver real warmth, lower energy bills, and a quieter home without losing the prewar character.
We bring modern efficiency to Upper Manhattan’s prewar apartment buildings. Our custom wood and aluminum-clad windows match co-op appearance standards and original profiles, paired with insulated low-E glass that cuts drafts, noise, and heating costs through Washington Heights’ exposed winters. We address cold-glass discomfort in steam-heated units and size every replacement to fit generous prewar openings. Each installation is coordinated around building access, and our crews work cleanly and respectfully inside occupied homes.
We will visit your apartment or co-op, take precise measurements, and present window options that cut drafts and improve efficiency.
