Neptune Construction NY Inc

Construction in Midtown East demands precision—especially when the job sits above the hum of Madison Avenue. Neptune Construction NY Inc operates from 515 Madison Ave, 9th Floor Suite 8153, a building that overlooks the grid of steel and glass that defines this part of the city. The firm handles everything from structural renovations to facade restorations, often working on projects where space is tight and timelines tighter. High-rise scaffolding and sidewalk sheds become temporary landmarks here, signaling another transformation in a neighborhood where change is constant.

Those managing a build-out or repair can reach the office at (212) 597-2661. Neptune’s scope includes concrete work, waterproofing, and tenant improvements, all executed within the constraints of New York’s permitting maze. A map pinpoints their exact location for anyone navigating the elevator banks and corridor turns of a 1960s office tower: directions. The area’s mix of pre-war co-ops and modern high-rises means every project carries its own set of challenges—none of them small.
