Greene Group Construction Corp — 24/7 emergency water damage restoration, fire damage restoration, mold remediation, and roofing in Sag Harbor, Suffolk County, Long Island.
Sag Harbor is an incorporated village spanning the Towns of Southampton and East Hampton, Suffolk County, with a population of about 2,772 as of the 2020 Census. First mentioned in 1707 and incorporated in 1846, the village was a major whaling port that rivaled Salem and New Bedford, Massachusetts, in importance until the 1830s.
The Old Whalers' Church, built in 1844 with its distinctive steeple, and the Sag Harbor Whaling and Historical Museum preserve the village's maritime heritage. On July 31, 1789, Sag Harbor was declared the first official U.S. port of entry, with the first customs house on Long Island.
Sag Harbor's housing includes historic 19th-century Federal and Greek Revival homes built by prosperous whaling captains and merchants, alongside more recent construction. These historic waterfront and near-harbor homes carry both age-related and flood-related vulnerability.
Sag Harbor sits along Gardiners Bay at the gateway to Peconic Bay, giving its waterfront village carries real storm-surge and tidal flood risk — the Old Whaler's Church steeple was destroyed in the 1938 hurricane, illustrating the village's storm exposure.
