An 1883 bluff-top village.

Wikipedia says Sea Cliff incorporated as a village in 1883; its library opened in 1894, and since 1968–70 the village offices and library have shared the former Sea Cliff Methodist Church and parsonage. It is part of the greater Glen Cove area. The village covers 2.0 square miles, about 45% of it water.

The Census Bureau's latest five-year survey counts about 2,000 homes, with a median year built of 1938. 17% went up in the 1950s, 57% before 1940, and 7% after 1980. 80% 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 88 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 76% of homes heat with utility gas and 16% 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 Sea Cliff 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.

Flood risk.

Laying FEMA's current flood map over the Census boundary, about 7% of Sea Cliff is in the high-risk (1% annual chance) flood zone (5.4% in zone VE, 1.5% 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.

Old houses.

The Census puts Sea Cliff's median build year at 1938, with 57% of homes built before 1940. Expect older drain lines, galvanized or mixed supply piping and past repairs layered on each other; we plan the work around what's actually in the walls.

Water: Liberty Utilities New York's Sea Cliff system.

EPA's service-area map puts essentially all residents on Liberty Utilities New York's Sea Cliff system; your bill is the final word. The main supplier's most recent 90th-percentile lead result was 0 ppb (none measured), 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.

Sea Cliff is an incorporated village, so plumbing permits go through the Village of Sea Cliff's building department, not the town.

Local reference points: Hempstead Harbor, Sea Cliff Avenue and Village Hall in the former Methodist church.
