Greene Group Construction Corp — 24/7 emergency water damage restoration, fire damage restoration, mold remediation, and roofing in Sayville, Suffolk County, Long Island.
Sayville is a hamlet on the South Shore of Long Island in the Town of Islip, Suffolk County, with a population of about 16,569 as of the 2020 Census. Founded by John Edwards in 1761, Sayville was once the center of the South Shore's oyster industry and became a bustling summer resort after rail service arrived in 1868.
The Long Island Maritime Museum in neighboring West Sayville showcases the historic oyster sloop Priscilla, a National Historic Landmark. Sayville also serves as a major embarkation point for ferries to Fire Island communities like Cherry Grove and Fire Island Pines.
Sayville's housing includes well-preserved Victorian and early 20th-century homes near the historic downtown, alongside more typical suburban construction. Waterfront and near-marina properties face greater exposure to tidal flooding than the hamlet's interior.
With Great South Bay frontage and status as a Fire Island ferry hub, Sayville carries real storm-surge and tidal flood risk for its waterfront and marina-adjacent neighborhoods.
