The Upper West Side is one of Manhattan’s most architecturally distinguished neighborhoods. Grand pre-war apartment buildings like the Ansonia, the Apthorp, and the Beresford define the avenues with their ornamental facades, deep window reveals, and elaborate cornices. Side streets between Central Park West and Riverside Drive are lined with brownstones and limestone rowhouses from the 1880s through 1910s. Many of these buildings retain their original windows — tall double-hung sashes with wavy glass and intricate mullion patterns that predate modern insulation by half a century. The result is a neighborhood full of beautiful, drafty apartments.
We specialize in pre-war buildings where architectural integrity is non-negotiable. Our team prepares co-op board applications, LPC submissions, and mock-up samples that demonstrate exact profile matches to existing windows. We offer wood-interior windows with slim sightlines that replicate the elegance of original millwork while delivering modern insulated glass units. Our installation process is clean, contained, and respectful of pre-war plaster walls and original woodwork.
We will visit your apartment or brownstone, assess your current windows, and navigate the co-op or landmark approval process with you.
