In short: Alex Glass Construction supplies and installs Pella windows and doors across Manhattan. On landmarked townhouses on the Upper East Side, Upper West Side and in the Village it is Pella Reserve or Architect Series matched to the approved divided-lite profile, with the Landmarks Preservation Commission filing prepared by us; in pre-war co-ops and condos it is Architect Series or Lifestyle double-hungs to the building standard, with the board package, insurance and scheduling handled. The Upper West Side landmark replacement in Pella Reserve is our proof. Call 929-235-1233 or request a free quote.
Manhattan window work is governed by two bodies before it is governed by the window: the Landmarks Preservation Commission, on the townhouse blocks of the Upper East Side, Upper West Side, Greenwich Village, Chelsea and Harlem, and the co-op or condo board, on nearly every apartment building. The LPC wants the replacement to match the historic window in profile, material appearance, divided-lite pattern and color; the board wants every window in the building to match the standard it has adopted, installed by an insured contractor on the building’s schedule. Pella fits both. Reserve reproduces putty-profile divided lites closely enough for a landmark approval, and Architect Series and Lifestyle double-hungs are on the approved standard of many pre-war buildings.
The Upper West Side landmark replacement is the townhouse case: Pella Reserve matched to the divided-lite profile the LPC approved, installed from inside with the facade protected. Our East 71st Street and Upper East Side townhouse work shows the same process with other lines.
Uptown: Upper East Side, Lenox Hill, Carnegie Hill, Yorkville, Upper West Side, Morningside Heights, Harlem, Hamilton Heights, Washington Heights, Inwood.
Midtown and downtown: Greenwich Village, West Village, East Village, SoHo, Tribeca, Chelsea, Gramercy, Murray Hill, Kips Bay, Turtle Bay, Hudson Square, Lower East Side.

Pella Reserve and Architect Series are approved regularly when the divided-lite pattern, profile and color match the historic window or the block standard; the Upper West Side replacement on this site is a Reserve approval. We prepare the filing.
If they meet the building’s window standard. Many pre-war co-ops list Architect Series or Lifestyle double-hungs as approved; we check the standard, prepare the alteration package and the insurance, and install on the building’s schedule.
