Charleston sits on the West Shore near the Arthur Kill, crossed by Arthur Kill Road and the West Shore Expressway. In the 1800s it was known as Kreischerville, after the brick works that dug the local clay, and the Kreischer Mansion still stands on its hill. Today the area mixes newer townhouse and detached home developments, large retail along Veterans Road West and industrial sites, with Clay Pit Ponds State Park Preserve nearby.

That mix makes Charleston more commercial than most South Shore neighborhoods. Businesses here need annual backflow tests, restaurant drain maintenance, gas piping and fast response when a restroom or water heater fails during business hours. Homeowners in the newer developments call us for water heaters, drains and pumps. We provide COIs, written estimates and 24/7 dispatch for both, and the same licensed crew handles plumbing, gas and sewer work.

Common plumbing issues in Charleston
Annual backflow tests for businesses
Commercial water services usually have a backflow preventer that must be tested every year by a certified tester and the results filed. A device that fails needs repair and a retest. Missing the deadline can bring violations. We test, repair and file, and we can keep your locations on a schedule so the deadline does not sneak up on you.
Restaurant drains in the shopping areas
Food service in the shopping centers sends grease and food waste down the line every day. Even with a grease trap, the downstream pipe slowly coats and narrows. Jetting on a regular schedule, timed around service hours, keeps the kitchen from closing for a backup. We also repair and replace sinks, faucets and floor drains in commercial kitchens.
Clay soil and wet basements
Charleston's ground was valuable for brickmaking because of its clay, and clay holds water. After heavy rain, water can sit against foundations and work into basements. A sump pump in a properly built pit, with a discharge that carries water well away from the house, solves most of it. We add battery backup for storms.
Newer townhouses and their first repairs
Homes built in the last few decades are reaching the age where water heaters, fill valves, shower cartridges and supply lines start to wear out. These are straightforward repairs, and we handle them with written estimates and a 1-year labor warranty. Catching a worn shower cartridge or a weeping supply line early also keeps water out of the ceiling below.

Plumbing in Charleston: FAQ
How often does my business need a backflow test?
In New York City, backflow preventers on commercial services are generally tested every year, with results filed with the city. We perform the test, make any repairs needed to pass and handle the filing, and we can remind you before the next one is due.
Can you jet our restaurant line overnight?
Yes. We schedule hydro jetting before opening or after close when possible. Jetting comes with a 45-day guarantee, and we can set up recurring visits so the line is cleaned before it closes up.
Do you handle both homes and businesses in Charleston?
Yes. We work on townhouses and detached homes in the newer developments as well as retail and industrial properties. The same licensed crew handles plumbing, sewer, gas and heating, and every job starts with a written estimate.
