Once Greenwich and Rum Point.
Wikipedia says the hamlet was historically known as Greenwich and Rum Point and took the name Roosevelt in the first half of the 20th century; a short-lived Roosevelt Police District formed in 1920 was absorbed by the Nassau County Police Department after 1925. The CDP covers about 1.8 square miles.
The Census Bureau's latest five-year survey counts about 4,600 homes, with a median year built of 1952. 21% went up in the 1950s, 30% before 1940, and 18% after 1980. 81% are single-family detached houses, 8% are two-family, and 77% are owner-occupied.
So a typical house here has drain and water lines around 74 years old unless they've been replaced. Slow drains in several fixtures, a gurgling floor drain or rusty water from one tap are signs to have the main line and supply piping checked. With so many pre-1940 homes, some still have galvanized or older supply piping in the walls; we plan repairs around what's actually there.
Oil to gas means new gas piping.
The ACS shows 64% of homes heat with utility gas and 23% with fuel oil. Switching means properly sized gas piping to the new equipment, and often to the water heater, range and dryer. We do the gas line work. We don't sell or deliver oil.
On the sewer.
Nassau County's health department lists Roosevelt's sewers under the Nassau County Department of Public Works (516-571-6841). A backup that stops at your house is usually in your own line to the street; we clear it and repair or replace the line. If neighbors are backed up too, call the county at 516-571-6841.
Flood risk.
Laying FEMA's current flood map over the Census boundary, about 6% of Roosevelt is in the high-risk (1% annual chance) flood zone (6.3% in zone A; shares of the Census area, water included). On a sewered street, a backwater (sewer check) valve on your house sewer line can keep a street-sewer backup from coming in through basement floor drains. We install them. If your water heater or gas appliances ever sat in flood water, have them checked before relighting.
Water: Liberty Utilities New York's Lynbrook system.
EPA's service-area map puts essentially all residents, with a small edge on the Village of Freeport's system on Liberty Utilities New York's Lynbrook system; your bill is the final word. Liberty's 2026 report on 2025 water for its Lynbrook Operations District says caustic soda or lime raises the pH to cut corrosion of household plumbing and iron is filtered out at 13 of its 20 well sites; total hardness ran 4.2 to 58.6 mg/L, which is soft. Across the whole district, Liberty's state-filed inventory counts 3,700 lead service lines and 15,239 of unknown material, so if your house predates 1940 it's worth knowing what your service line is. For a leak at the curb or in the street, call your water supplier. For anything on your side of the meter, call us.
Permits.
Roosevelt is an unincorporated hamlet, so plumbing permits go through the Town of Hempstead Building Department (One Washington Street, Hempstead).
