Polo fields and Gold Coast estates.
Wikipedia says that after the Civil War wealthy New Yorkers came here to raise horses, hunt and play polo at the Meadow Brook Polo Club (founded 1881), and built estates such as John Shaffer Phipps' Westbury House, now Old Westbury Gardens. The village split off from Westbury and incorporated in May 1924, with about 500 residents; its pull was strong enough that Robert Moses moved the Northern State Parkway about five miles south. It covers 8.6 square miles, all land.
The Census Bureau's latest five-year survey counts about 1,100 homes, with a median year built of 1969. 19% went up in the 1950s, 15% before 1940, and 38% after 1980. 95% are single-family detached houses, and 93% are owner-occupied.
So a typical house here has drain and water lines around 57 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.
Oil to gas means new gas piping.
The ACS shows 50% of homes heat with utility gas and 33% 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.
Cesspools and septic, mostly.
Nassau County's health department list of sewer collection districts shows Old Westbury as not publicly sewered, so expect a cesspool or septic system. We clear the line from the house, but a full or failing cesspool is a job for a cesspool or septic contractor; we don't do cesspool work, and we don't install septic systems.
Little mapped flood risk.
FEMA's current flood map puts none of Old Westbury in the high-risk flood zone.
Big lots, long runs.
Large lots mean long water service lines and long drain lines out to the cesspool or septic system. A third of homes still heat with oil (Census), so an oil-to-gas switch usually means new gas piping to the boiler and water heater.
Water: Village of Old Westbury's water system.
EPA's service-area map puts about 97% of residents on the Village of Old Westbury's water system, with about 2% on the Jericho Water District; your bill is the final word. The main supplier's most recent 90th-percentile lead result was 5.4 ppb, under the 15 ppb action level; lead usually comes from a home's own pipes and fixtures, so results vary house to house. In EPA's UCMR 5 testing, the main supplier reported no PFOA or PFOS. 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.
Old Westbury is an incorporated village, so plumbing permits go through the Village of Old Westbury's building department, not the town.
