The Three Points and the Gold Coast.
Wikipedia says the village is named for the Sands family, who settled on Cow Neck in colonial times. It incorporated in 1910 and in 1912 absorbed the villages of Barker's Point and Mott's Point; in 1932 it annexed Harbor Acres. Daniel Guggenheim bought Hempstead House (formerly Castle Gould) in 1917, and Harry Guggenheim built Falaise nearby in 1923; both are now in Nassau County's Sands Point Preserve. In the 1960s many homes were built on one-acre lots. The village covers 5.6 square miles, about a quarter of it water.
The Census Bureau's latest five-year survey counts about 900 homes, with a median year built of 1963. 26% went up in the 1950s, 12% before 1940, and 24% after 1980. 99% are single-family detached houses, and 97% are owner-occupied.
So a typical house here has drain and water lines around 63 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 58% of homes heat with utility gas and 38% 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.
Water heaters in Sands Point.
The Census Bureau's survey puts the average owner household at 3.26 people; 99% of homes have three or more bedrooms and 86% have four or more. A tank sized for a smaller household, or one full of sediment, is what runs out first when several people shower back to back. When a heater fails, we size the replacement to the household and the number of bathrooms, not just to the label on the old tank. With this much oil heat, many houses make hot water from the boiler (a coil or an indirect tank), so an oil-to-gas switch usually means a new water heater and gas piping too; we do both.
Cesspools and septic, mostly.
Nassau County's health department list of sewer collection districts shows Sands Point as not publicly sewered, and Wikipedia says the village depends on cesspools and septic systems. 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.
Flood risk.
Laying FEMA's current flood map over the Census boundary, about 32% of Sands Point is in the high-risk (1% annual chance) flood zone (27.3% in zone VE, 5.2% in zone AE; shares of the Census area, water included). If your water heater or gas appliances ever sat in flood water, have them checked before relighting.
Water: Village of Sands Point's water system.
EPA's service-area map puts about 66% of residents on the Village of Sands Point's water system, with about 34% on the Port Washington Water District; your bill is the final word. The main supplier's most recent 90th-percentile lead result was 2.1 ppb, under the 15 ppb action level; lead usually comes from a home's own pipes and fixtures, so results vary house to house. The main supplier wasn't part of EPA's 2023–2025 UCMR 5 PFAS testing, so its annual water quality report is the place to look before choosing a filter. 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.
Sands Point is an incorporated village, so plumbing permits go through the Village of Sands Point's building department, not the town.
Local reference points: the Sands Point Preserve (Hempstead House and Falaise), the Sands Point Light and the John Philip Sousa House.

Questions
Sands Point plumbing FAQ
Do you cover all of Sands Point?
Yes, all of Sands Point (ZIP 11050), plus the neighboring communities listed below.
Is Sands Point on a sewer or a cesspool?
Most homes here use a cesspool or septic system; a sewer district charge on your tax bill means you're connected. We clear the house drain line, but cesspool pumping or replacement is for a cesspool or septic contractor.
Who supplies my water?
EPA's service-area map puts about 66% of residents on the Village of Sands Point's water system, with about 34% on the Port Washington Water District. Your bill says which. For leaks at the curb or meter, call the supplier; inside the house, call us.
What size water heater does a Sands Point house need?
It depends on the people and bathrooms, not the house's age. Sands Point's average owner household is 3.26 people and 99% of homes have three or more bedrooms, so we size the tank to your household and fixtures, and check the gas line or wiring, flue and relief valve when we install it.
Can you handle the gas piping when I switch from oil to gas?
Yes, we install and repair gas lines for heating equipment and appliances.
When can I reach you in Sands Point?
We answer calls 24/7. We're open Monday through Saturday and closed on Sunday. Call (631) 644-2084.
