Smell gas?Get out first. Call from outside.
Gas work is licensed work for a reason. Every line we run or repair gets pressure-tested, permitted and inspected before anything is turned back on. No shortcuts, no exceptions, no handyman prices.
- Licensed for fuel gas systems
- Every repair pressure-tested
- Permits filed & inspected

If you can smell it right now, stop reading.
Don't flip a light switch. Don't unplug anything. Don't use the phone inside the house, and don't go hunting for the source. A switch is a spark. Get everyone out, leave the door open behind you, and go to the street or a neighbour's.
From outside, call your gas utility's emergency line first — that call is free and they will come out — then call us. We're licensed for fuel gas systems, and nothing gets relit until the line has passed a pressure test.
Why this one isn't a handyman job
What a licensed gas job actually involves
Running a gas line looks like plumbing and isn't. Here is what has to happen on every single one, whether it's a dryer connection or a whole-house repipe.
- Step 01
- Sized for the load Pipe diameter is calculated from the total BTU demand and the length of the run. Undersize it and every appliance on that line starves, which shows up as a lazy yellow flame and incomplete combustion rather than as an obvious fault.
- Step 02
- Permit before the work A gas modification permit runs $120–$280 depending on the township, with one or two inspections. Work done without one is unpermitted gas piping in your house, which is a problem for your insurer and a serious problem at closing.
- Step 03
- Pressure-tested The line is isolated and held under test pressure to prove it's tight before a single appliance is connected. This is the step that gets skipped by people working cheap, and it's the only one that actually proves the work.
- Step 04
- Inspected, then lit The township inspector signs it off, appliances get connected and lit, and combustion is checked at the appliance. You get the paperwork, which matters when you sell the house.
All of it is done to the NJ Uniform Construction Code by a master plumber licensed for fuel gas systems. If somebody quotes you gas work without mentioning a permit or a pressure test, that is the whole story about the quote.

What do you need doing?
Four jobs cover almost everything we're called for. Pick yours and you'll see what's involved and roughly what it costs.
Range, dryer, generator, fire pit, pool heater
An extension off the existing system to a new appliance. We size the run for the added load rather than teeing off whatever's nearest, because the second one is how you end up with three appliances that all under-fire.
Located, repaired, then proved
If you can smell it, leave the building and call the utility before you call us. If you suspect it — a faint smell that comes and goes, a bill that jumped, a pilot that keeps dropping out — we test the system, locate it, repair it and pressure-test the repair.
Old black iron, replaced properly
Older North Jersey houses run on black iron that's been extended by four different people over sixty years. A repipe puts the whole system back on a single sized design, with proper shut-offs at each appliance and a system that can actually be tested as a whole.
Gas line first, then the equipment
An oil-to-gas conversion is really three jobs: getting gas to the house and sized for the heating load, decommissioning the oil tank, and fitting the new equipment. We coordinate all of it including the soil testing if the tank was buried.
Flat rate, no bait

Questions we get a lot
What does gas line work cost?
Leak detection is $285. An extension to a new appliance runs $385–$985 depending on the length of the run and what it has to pass through. A full home repipe is $2,500–$7,500. The township permit adds $120–$280. All of it is quoted in writing before work begins.
What should I do if I smell gas?
Leave the building. Don't flip switches, unplug anything, or use a phone indoors — a switch is a spark. Leave the door open behind you. From outside, call your gas utility's emergency number, which is free and will get someone out, and then call us. Nothing gets relit until the line passes a pressure test.
Do I need a permit for gas work?
Yes, for anything beyond replacing a like-for-like appliance connector. A gas modification permit is $120–$280 depending on your township, with one or two inspections. Unpermitted gas piping is a genuine problem with insurers and it will surface during a home sale. We file it and coordinate the inspection.
Can you run a line for a generator or a pool heater?
Yes, and both are common. The important part is sizing — a generator adds a large intermittent load and the line has to carry it alongside everything else without starving the furnace. We calculate the total BTU demand rather than teeing into whatever pipe is closest.
What pipe do you use?
Black iron for most runs, and CSST where it's the right tool and properly bonded. We don't reuse questionable old fittings to save an hour, and we don't use flexible connectors as concealed piping, which is a thing we've been called out to correct more than once.
My gas bill jumped but nothing changed. Could it be a leak?
It can be, and it's worth testing. It can equally be a furnace that's over-firing, a water heater with a failing thermostat, or simply a colder month than the one before. A system test tells you definitively, and $285 is cheap against guessing at it for a winter.
