One glazing subcontractor for the whole building: window packages, storefront, curtain wall, entrance doors, glass railings and panels on new construction in Nassau and Suffolk counties, with shop drawings, fabrication at our shop or factory-direct supply, and installation by our own crews.
In short: Alex Glass Construction is a glazing contractor for builders and developers on Long Island. We take the window and glass scope of a new building or a custom house as one package: take-off from the architect’s set, shop drawings, fabrication of the aluminum at our shop or factory-direct supply from several manufacturers we represent, and installation by our own crews. Surfview Towers in Long Beach (every window on an oceanfront building) and the complete envelope on a new custom house in Woodmere are that package. Call 929-235-1233 or request a free quote.
Long Island work splits into two markets: custom houses and small multi-family on the South Shore and the Five Towns, where the owner and the builder want one company for the whole envelope, and mid-rise, retail and commercial buildings along the Nassau and Suffolk corridors, where the GC wants one glazing sub for windows, storefront, curtain wall, entrances and glass railings. We do both, from the same drawings and the same crews.
25 Franklin Boulevard in Long Beach replaced every window on a seven-story oceanfront building; Amherst Drive in Woodmere is the complete exterior envelope of a new custom house: stucco, black ACM panels, Pella windows, steel canopy and box dormers. Long Island windows, doors and glass covers the residential side in detail.

Call 929-235-1233 or send the drawings for a bid.
Yes. Most of our new-construction work is under a GC or directly for the developer: we bid from the set, submit shop drawings, fabricate, deliver and install, and coordinate with the framer, mason and facade trades.
Yes. Every opening is drawn, with the system sections, glass make-up and the energy and performance data the architect and the filing need, and nothing is fabricated until the drawings are approved.
Yes. Supply to the window schedule with shop drawings, delivery to the floor and a site start for your crew.
Yes. We are an authorized distributor for several manufacturers in China and order windows, doors, curtain wall and railings directly, with survey, shop drawings, submittals, customs, delivery, installation and warranty handled by us locally. Where a named European or American system is the right answer, we quote it alongside.
Order from approved shop drawings as soon as the openings are framed or the masonry is set: three to twelve weeks for stocked and fabricated lines, three to four months for factory-direct container orders and imported European systems.
Yes, and that is the point: one contractor, one set of drawings and one crew for the windows, the ground-floor storefront, the entrance and the balcony and roof railings.
Yes. Long Beach, Lido Beach, Atlantic Beach and the Five Towns are regular work for us; Surfview Towers on the Long Beach boardwalk had every window replaced with units specified for the ocean exposure.
Yes, for building packages and commercial work. Smaller residential jobs in eastern Suffolk are quoted with travel included.
