Working on the Upper East Side
Glass work inside co-ops, condos and townhouses
Most of our work here happens inside occupied prewar co-ops, postwar condo towers and townhouses, and that shapes how we plan every job. Before anything is cut we confirm the building alteration rules, send a certificate of insurance to the managing agent and book the service elevator for delivery and installation.
Prewar bathrooms often have walls that are out of plumb and floors that slope toward the drain, so we measure on site with laser tools and fabricate to the real opening, not to the drawing. Townhouse renovations bring other questions, such as long stair runs that suit glass railings or garden-level rooms that need more light. Our showroom at 1400 York Avenue is close by, so you can see glass samples, hardware finishes and edge options before you decide.

What we install in Upper East Side homes
Frameless Shower Enclosures
Fixed panels, hinged doors and sliding enclosures cut to the actual opening.
Glass Factory NYC has been measuring, fabricating and installing custom glass for Upper East Side homes for years. We work in prewar co-ops along Park and Fifth Avenue, postwar condo towers near York Avenue and townhouses on the side streets between Lexington and Madison. Every project starts with an on-site measurement, because older buildings rarely have perfectly square walls or level floors.
Our showroom at 1400 York Avenue is a short walk for most clients in the neighborhood, so you can see frameless shower doors, mirror edges and hardware finishes in person before you decide.

FAQ
Questions from Upper East Side homeowners
