Licensed Gas Leak Detection in NJ
If you smell gas in your NJ home, leave the building first and call your gas utility from outside. Then a licensed plumber finds and repairs the line. That order matters, and it's the part most people get wrong. Maccabi Plumbing & Heating handles gas leak detection across NJ as a licensed NJ Master Plumber (#13345), answering calls 24 hours a day Monday through Saturday. Here's what homeowners rarely hear. The utility will confirm the leak and shut gas off at the meter for free, but by law they do not repair your interior gas piping. That's a licensed plumber's job, and the line has to pass a pressure test and a municipal re-inspection before gas comes back on. We handle that whole repair path, not just the alarm.

Smell Gas? Do This First
If you smell gas right now, treat it as an emergency and get out before anything else. The correct sequence is short and worth knowing before you need it
- Leave the building immediately. Take everyone with you, and leave the door open on your way out.
- Don't touch anything electrical. No light switches, no phones, no appliances inside. A spark is the danger.
- Call the utility from outside, from a safe distance. New Jersey Natural Gas at 1-800-GAS-LEAK, or PSE&G at 1-800-880-7734. They respond around the clock.
- Then call Maccabi for the repair. Once the utility has made the area safe, a licensed plumber locates and fixes the line.
PSE&G's own guidance is blunt. If you smell gas, leave the area immediately and call the emergency line from a safe location. Natural gas is odorless on its own, and utilities add mercaptan, a sulfur compound that smells like rotten eggs, precisely so leaks get caught by smell (PSE&G / American Gas Association safety guidance). For a middle-of-the-night situation, our 24-hour emergency plumber service covers the repair side Monday through Saturday.
How Do You Detect a Gas Leak?
A plumber detects a gas leak with three tools used together. An electronic combustible-gas detector to find the general source, a soap-solution bubble test to pinpoint the exact fitting, and a manometer pressure test to confirm the whole system holds. In New Jersey, gas piping work is restricted to a licensed plumber (#13345), and the repaired line must pass inspection before gas is restored.
Each tool does a specific job. The combustible-gas detector sweeps a line or an appliance connection and picks up concentrations your nose can't localize. The soap solution goes on suspect joints, and a leak blows steady bubbles, so we know it's the fitting and not the pipe. The manometer is the honest test. We cap the system, pressurize it, and watch the gauge. If it holds, the line is tight. If it drops, there's still a leak and we keep looking. A fitting leak and a corroded-pipe leak get fixed differently, and the pressure test tells them apart. If you also suspect water intrusion, that's separate hidden water leak detection work.
A combustible-gas indicator reads in parts per million, and that sensitivity is the point. A joint can weep gas at a level too low to smell in a drafty basement but high enough to build up in a closed utility closet next to the boiler. We sweep the meter, the regulator, every threaded joint, and each appliance shut-off in turn, and the meter shows where the concentration climbs. On a suspected underground service leak we also bar-hole the soil along the run, because a buried line can leak well away from where the odor first shows up inside.

What Your Service Visit Includes
A gas leak service visit covers the full path from finding the leak to getting gas legally restored. We don't stop at "there's a leak here." A typical visit runs like this
- Locate and confirm the leak with the detector and soap test.
- Isolate the affected section and shut it down safely.
- Repair or replace the leaking section, whether it's a single fitting or a corroded run of old black-iron pipe.
- Pressure-test the repaired system with a manometer to prove it holds.
- Coordinate the municipal re-inspection and the utility's gas restoration.
That last step is the one homeowners don't expect. Utility crews shut off an active leak at the meter, but they hand the interior repair back to you. The line then needs a permit, a passed pressure test, and a town inspection before the utility turns gas back on. We manage that end to end.
Gas Line Repair & Installation
Beyond finding leaks, we repair and install the gas piping itself. In older northern-NJ homes that means a lot of corroded black-iron pipe replacement, plus new runs when someone adds an appliance. Common jobs include
- Replacing corroded or leaking black-iron gas pipe
- New gas runs for a range, dryer, gas generator, or pool heater
- CSST (flexible corrugated stainless) installation where it suits the layout
- Capping abandoned lines left from a removed appliance
- Correcting improvised or unpermitted gas runs from prior work
Gas work has its own rules that separate a code repair from a handyman patch. Threaded black-iron joints get yellow gas-rated PTFE tape or an approved thread sealant, never the white tape used on water lines. Every appliance connection needs a drip leg, the short capped nipple that lets scale and moisture drop out before they reach a burner or valve. New CSST has to be bonded to the home's grounding system, because that thin corrugated tubing is vulnerable to a nearby lightning strike. And a new run has to be sized to the appliance's BTU demand, since an undersized line starves a furnace or tankless heater and makes it short-cycle. These are the points an inspector checks.
For commercial buildings and rentals, commercial gas leak service for property managers covers the same work with the habitability and liability side handled.
Pricing, explained
Pricing & What to Expect
Gas leak service cost depends on the detection, the length of pipe replaced, and the permit and inspection. A single fitting or appliance-connection leak is a smaller job than replacing a corroded run of black-iron pipe through a finished basement. We explain the trip fee upfront and give you a clear scope before starting. One honest note. Your gas utility's leak check is free, but that's the check and the shutoff, not the repair. The interior repair is a paid, permitted, code-compliant job, and we don't blur that line.

Know the warning signs
Signs of a Gas Leak
The clearest sign of a gas leak is the rotten-egg smell from the added mercaptan, but there are others worth knowing. Any one of these is a reason to call
A rotten-egg or sulfur odor, faint or strong
Hissing near a gas line, meter, or appliance connection
A pilot light that won't stay lit, or burners that keep going out
Dead or dying vegetation in a line over the buried service pipe
A gas bill that jumps with no change in use
Physical symptoms indoors. Dizziness, headaches, nausea that ease when you step outside
Why this is an evacuate-first situation and not something to investigate calmly. Natural gas is flammable at roughly 5 to 15% concentration in air (U.S. PHMSA pipeline-safety guidance). Inside a closed house, that range is reachable, which is why the first move is always out the door.
Why it pays to do it right
Benefits of Professional Gas Leak Detection
Hiring a licensed plumber for gas work is not just safer, it is the only legal way to get gas restored in New Jersey.
It is the law here. Only a licensed plumber may perform gas piping work in NJ, and Maccabi holds Master Plumber License #13345.
Every repair gets pressure-tested with a manometer and passed at municipal re-inspection, the two steps a utility will not do before turning gas back on.
We pull the permit, so the work is on record and your gas restoration is not held up by missing paperwork.
One contractor, start to finish. Bonded and insured, we locate the leak, fix the line, and coordinate the inspection instead of handing you off.
Code details a handyman skips get done right. Yellow gas-rated sealant, a drip leg at every appliance, CSST bonded to ground, and lines sized to BTU demand.
Qualifying repairs carry the 1-year Maccabi Guarantee, and we explain the trip fee and scope before we start.
Where We Work
We work across northern NJ's Essex, Passaic, Morris, Bergen, and Union county towns, and the housing stock here drives a lot of our gas calls. Pre-1950 homes in West Orange, Montclair, and Passaic run decades-old black-iron gas piping and shut-off valves that seize with age, so a valve that won't turn is a common find. Older homes that converted to gas heat often carry improvised or unpermitted runs from earlier work, and we find and correct those during detection. The pattern is the same. Old pipe, old valves, and work that never got inspected.
