Greene Group Construction Corp — 24/7 emergency water damage restoration, fire damage restoration, mold remediation, and roofing in Manhasset, Nassau County, Long Island.
Manhasset is an affluent hamlet on the North Shore of Long Island in the Town of North Hempstead, Nassau County, with a population of about 8,176 as of the 2020 Census. First settled by Europeans in 1643 and known historically as Little Cow Neck, the hamlet was renamed Manhasset in 1840, from an Algonquian word meaning "neighbor island."
Plandome Road anchors Manhasset's affluent downtown shopping district. The hamlet sits partially on the Cow Neck Peninsula along Manhasset Bay, and North Hempstead's Town Hall is located here, making Manhasset the town seat.
Manhasset's housing includes luxury homes built after the Long Island Rail Road's 1898 expansion drew wealthy New Yorkers to the area, alongside more typical 20th-century construction. Waterfront and near-bay homes face greater exposure to coastal moisture.
With frontage on Manhasset Bay, Manhasset carries real storm-surge and tidal flood risk for its waterfront neighborhoods, while its downtown and inland residential sections are comparatively better protected.

Greene Group Construction manages every phase under one contract.
