Greene Group Construction Corp — 24/7 emergency water damage restoration, fire damage restoration, mold remediation, and roofing in Hempstead, Nassau County, Long Island.
Hempstead is an incorporated village in the Town of Hempstead, Nassau County, with a population of about 58,887 as of the 2020 Census, making it the largest village in New York State by population. Settled around 1644, Hempstead was the original town spot where English and Dutch settlers first built their community.
St. George's Episcopal Church and Christ's First Presbyterian Church — the first Presbyterian church founded in the United States — are historic landmarks in the village. Hofstra University, founded in Hempstead in 1935, anchors the village's northern edge.
Hempstead's housing is dense, with many homes built in the early-to-mid 20th century across its 3.7-square-mile footprint. High housing density combined with aging plumbing and roofing in older homes makes water damage a fast-spreading risk between properties.
Hempstead sits inland in central Nassau County with no direct waterfront, so storm-surge risk is low. Water damage here is more commonly driven by aging plumbing in the village's dense, older housing stock and heavy rainfall overwhelming storm drains.

Mold is a serious health hazard that grows fast after any water event.
