The post-war house, times 13,000.
Hicksville started as a railroad stop. Valentine Hicks bought the land in 1834, and the LIRR stopped there by 1837. It stayed farm country, known for cucumbers and later potatoes, until the post-World War II building boom. The Census Bureau's latest five-year survey shows the result: about 13,600 homes, 93% single-family detached, with a median year built of 1955. 58% were built in the 1950s alone, 82% before 1960, and only 9% after 1980. 86% are owner-occupied.
Some national franchise pages describe Hicksville as "pre-war buildings and row houses." The Census data says otherwise. This is a neighborhood of detached 1950s houses. Many still have original drain and supply piping that's now about 70 years old. The most common big job in a house like that is the main drain line to the street: roots, cracks, sags, and backups that come back after a snaking.
Four in ten homes still heat with oil.
That's the highest oil share of the five areas in this series. The ACS shows 50% of Hicksville homes heat with utility gas and 40% with fuel oil. Every conversion needs gas piping run and sized for the new equipment, and often for a gas water heater, range or dryer. We do gas line work. We don't sell or deliver oil.
Your water district has invested heavily in treatment.
Hicksville's public water comes from the Hicksville Water District, not a private company. New York set a maximum contaminant level of 1.0 part per billion for 1,4-dioxane in 2020. The district says its first Advanced Oxidation Process (AOP) system, at Plant No. 4, is operational. It is building AOP plus granular activated carbon treatment at other plants and estimates capital costs above $70 million. The district also says wells affected by emerging contaminants were taken offline so customers get water that meets the standards. If you want home filtration on top of that, it's a personal choice. We'll size a system to your goals and the district's latest Annual Water Quality Report, not to scare tactics.

My main drain backs up every few months. Why does snaking only help for a while?
In 1950s houses, recurring backups usually mean roots or a damaged section in the main line, not just a clog. Snaking clears it temporarily.
I'm switching from oil to gas. Can you run the gas line?
Yes. We install and repair gas piping for appliances.
Is Hicksville water safe? Do I need a filter?
The Hicksville Water District reports that it treats for 1,4-dioxane and takes affected wells offline to meet state standards. A filter is optional. If you want one, we'll match it to the district's water report.
There's water in the street outside my house. Who do I call?
The Hicksville Water District at (516) 931-0184 (24 hours). If it's on your side of the meter, call us.
Do you install septic systems?
No. We clear the line from the house to an existing septic tank, but we don't install septic systems, and we don't do cesspool work.
