Marvin Signature Ultimate, Modern, Elevate and Essential windows and doors for custom houses, renovations and waterfront homes across Nassau and Suffolk, surveyed, supplied and installed by Alex Glass Construction.
In short: Alex Glass Construction supplies and installs Marvin windows and doors across Long Island: Signature Ultimate and Elevate casements, double-hungs and French doors on custom houses in the Five Towns and on the North Shore, Signature Modern where an architect has drawn large glass, and Elevate or Essential fiberglass with laminated glass on the South Shore and the barrier islands, where salt air and wind pressure decide the specification. We survey, quote per opening, file the town permit and install with our own crews. Call 929-235-1233 or request a free quote.
Long Island Marvin work is mostly houses: new custom houses and gut renovations in the Five Towns, Great Neck, Manhasset and the North Shore, where the owner or the architect has specified a wood-interior window with divided lites and a black or bronze exterior, and the choice is between Marvin Signature Ultimate, Pella and Andersen. Marvin wins where the sizes or shapes are custom, where the interior wood species and finish matter, or where the architect wants the narrow frames and large fixed glass of Signature Modern. The custom house on Amherst Drive in Woodmere shows the kind of complete envelope we deliver in the Five Towns, there with Pella; the same package is quoted in Marvin on request.
On the South Shore and the barrier islands, Long Beach, Lido Beach, Atlantic Beach, the Hamptons, the ocean sets the specification: design pressure, laminated or impact-rated glass where the code or the insurer requires it, stainless hardware, and a frame that does not mind salt air. Marvin Elevate and Essential, with Ultrex fiberglass to the weather, are built for that, and Signature Ultimate’s aluminum cladding takes a marine-grade finish. Our coastal specification is on Long Island windows, doors and glass.
South Shore and the Five Towns: Woodmere, Cedarhurst, Lawrence, Hewlett, Long Beach, Lido Beach, Atlantic Beach, Oceanside, Rockville Centre, Merrick, Bellmore, Wantagh, Massapequa.
North Shore and central Nassau: Great Neck, Manhasset, Port Washington, Roslyn, Sands Point, Old Westbury, Garden City, Jericho, Syosset, Oyster Bay, Locust Valley, Glen Cove.

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.
Elevate or Essential with Ultrex fiberglass to the weather, laminated or impact-rated glass where the design pressure or the insurer requires it, and stainless hardware; Signature Ultimate with a marine-grade clad finish where the wood interior is wanted.
