The rebuilt townhouse on East 71st Street and the penthouse at 205 East 69th Street are our Marvin work. Call 929-235-1233 or request a free quote.
Most Marvin work in Manhattan is a townhouse, and most townhouses on the Upper East Side, the Upper West Side and in the Village are landmarked. The Landmarks Preservation Commission looks at the window from the street: the profile, the meeting rail, the divided-lite pattern and the color. Marvin Signature Ultimate is built to order in wood with aluminum cladding, with simulated or authentic divided lites in any pattern, which is why it is approved regularly on these blocks. East 71st Street is the example: Marvin Ultimate wood double-hungs on the street rooms of a rebuilt townhouse, Low-E3 argon glass at a U-factor of 0.28, with black aluminum door walls on the terraces at the rear where nobody from the street can see them.
The second market is the pre-war co-op, where the building has a window standard and an alteration agreement and the board wants drawings, insurance and a schedule. Ultimate or Elevate double-hungs in the building’s color, installed one apartment at a time. The third is the penthouse or the rear extension: Marvin terrace doors and French doors, as at 205 East 69th Street, where a Marvin outswing door was flashed into the brick beside custom steel windows.
Upper Manhattan: Upper East Side, Lenox Hill, Carnegie Hill, Yorkville, Upper West Side, Morningside Heights, Harlem, Hamilton Heights.
Midtown and downtown: Greenwich Village, West Village, East Village, Chelsea, Gramercy, Murray Hill, Turtle Bay, SoHo, Tribeca.
Townhouse fronts usually need a sidewalk shed or a pipe scaffold, which we arrange; co-ops are scheduled to the building’s rules. For the rest of what we do in the borough see Manhattan windows, doors and glass and Upper East Side townhouse windows.
More projects are added to the portfolio as they finish.
Alex Glass Construction supplies and installs Marvin windows and doors across Manhattan: survey, quote per opening, drawings for the board or the permit, and installation by our own crews. Call 929-235-1233 or send photos of the openings.
Signature Ultimate where the facade is landmarked or the detailing has to be right, Signature Modern for large contemporary glass, Elevate for a wood interior with a maintenance-free fiberglass exterior, Essential for rear, side and utility openings or volume work. We quote two lines side by side when the choice is close.
Typically six to twelve weeks from the approved order, depending on the line, finish and shape; custom colors and shapes take the longest. Installation on a house usually runs one floor per day.
It depends on the line, size, divided lites, finish, glass and the installation conditions. We quote per opening with everything named so you can compare against any other Marvin dealer, and the quote is free.
Usually, when the line, the divided-lite pattern and the profile match what the designation or the block standard requires; Signature Ultimate is accepted regularly. We prepare the filing with elevations and sections.
Yes. We work to the building’s window standard and alteration agreement, supply the insurance and drawings the board requires, and schedule around the building’s rules.
