Replacement windows in Queens in thermally broken aluminum, uPVC, Pella, Andersen and Marvin clad-wood and steel: measured by us, ordered to our survey, installed by our own crews one opening at a time, with the co-op, DOB or Landmarks approvals prepared.
In short: Alex Glass Construction replaces windows in Queens: full-frame or insert replacement in thermally broken aluminum, uPVC, Pella, Andersen and Marvin clad-wood, or steel, with Low-E argon glass, laminated or acoustic glass where the street demands it. We measure every opening, order to our own survey, prepare the co-op, DOB or Landmarks package, and install one opening at a time with the room weather-tight by the end of the day. Survey and quote are free. Call 929-235-1233 or request a free quote.
Queens window replacement is co-ops and houses. The garden co-ops of Jackson Heights and Forest Hills, the towers of Rego Park, Kew Gardens, Flushing and Bayside each have a window standard and an alteration agreement, and the work is one apartment at a time to the building rules. The houses of Fresh Meadows, Bayside, Jamaica Estates, Howard Beach and the Rockaways are full-house replacements, often with a sunroom or a sliding door added; 130 Beach 120th Street in Rockaway Park is custom aluminum windows and doors on the oceanfront, and 165-19 Jamaica Avenue is aluminum double-hungs on a mixed-use building. The Jamaica Estates sunroom doors show the custom aluminum side.
Our supply and installation for new buildings in Long Island City and Astoria is on glass contractor for builders and developers in Queens; the borough overview is Queens windows, doors and glass.
Western Queens: Long Island City, Astoria, Sunnyside, Jackson Heights.

Like-for-like replacement in a house needs no DOB permit; a change to the opening does, through the architect. Jackson Heights, Sunnyside Gardens, Douglaston, Hunters Point and Ridgewood are historic districts where a street-facing window is a Landmarks Preservation Commission permit, which we check and file. Co-ops want the alteration package, insurance and a schedule. On the Rockaway peninsula the design pressure and the flood zone change the specification. Installation is one to a few openings per crew per day, each opening closed and sealed the same day.
Full-frame against insert replacement, and the four sizes of an opening, are explained on window replacement and masonry opening, rough opening, unit size; how we measure is on how we measure a window opening.
More projects are added to the portfolio as they finish.

It depends on the number and size of openings, the material and line, the glass, and the installation conditions (scaffold, landmark filing, co-op package). We quote per opening with everything named, and the survey and quote are free.
Full-frame removes the old frame and replaces the flashing; insert leaves it in place and fits a smaller unit inside it. Full-frame is right when the old frame leaks or rots; insert when it is sound and the budget or the building rules point that way.
Three to twelve weeks from the approved order by line, longer for imported systems; installation runs one to a few openings per crew per day, with each opening closed and sealed the same day.
