Natural gas leaks present immediate risks. If you smell gas, leave immediately, call your gas utility from outside, then call us for licensed repair. Never re-enter until cleared.
Repair covers leaks, damaged sections, and pressure problems in existing gas lines. Installation covers new gas lines run to a location that doesn't currently have one — a new stove, dryer, or outdoor grill, for example. Appliance hookups cover connecting a gas appliance to an existing line, including moving a stove or dryer during a kitchen or laundry renovation. Water heaters that run on gas fall into this category too — see water heater service if that's the appliance in question.
Gas line work in NYC is regulated, and new installations or significant modifications typically require DOB permitting and inspection before the gas utility will turn service on. We handle work to code as a matter of course — ask us directly about permit requirements for your specific job, since they vary by scope and building type.
Unlike most plumbing, gas line work carries a real safety consequence if it's done wrong — an undetected leak isn't a slow drip you'll notice over weeks, it's a hazard from the moment the line is pressurized. That's why NYC requires gas work to be performed by or under the supervision of a licensed master plumber, and why we test every gas connection with calibrated equipment before signing off, not just a visual check.

Older gas lines, especially in pre-war NYC buildings, can corrode over decades as the metal degrades. Corrosion is usually caught during a routine inspection before it develops into a full leak.
Connections at appliance shut-off valves are a common leak point, particularly after an appliance is moved or reconnected without a proper fitting check by a licensed plumber.
Adding a new gas appliance to an existing line without first checking its remaining capacity can lead to pressure problems across every appliance already connected to that same line.
Renovation work, especially drilling or demolition near a wall with a concealed line, is a genuinely common cause of accidental gas line damage in older buildings.
A gas line visit starts with a pressure test of the affected line to locate any leak and check overall system pressure, not just the specific point you called about. If a leak is found, we'll explain exactly what's causing it and what repair it needs before starting work — gas line repairs aren't something to greenlight without understanding the scope first.
For new installations or appliance hookups, we size the line to the appliance's actual gas demand, not just match whatever pipe is closest. Once work is done, every connection is pressure-tested and checked with calibrated gas detection equipment before we consider the job complete — a visual check isn't sufficient for gas work, and we don't treat it as one.
Building type affects the visit too. A single-family house or apartment with its own dedicated line is usually the simpler case. A restaurant or multi-unit building with several appliances sharing a line needs more careful pressure and capacity checking across the whole system, not just the fixture in question, since one undersized section can affect pressure to everything downstream of it.
For suspected leaks: leave the building, call 311 or your gas utility to shut off supply, then call us.
Full pressure test to identify leak locations and assess the entire gas line system.
All gas work is by NYC-licensed master plumbers, meeting all utility and NYC DOB standards.
We test all connections, verify pressure, and don't leave until the system is certified safe.
