Gas Lines
Gas piping runs on one rule that outranks every other: safety first, diagnosis second. If you smell gas (the sulfur, rotten-egg odorant), leave the building, do not switch anything on or off, and call 911 and your gas utility from outside. Everything else on this page assumes the area is safe.
With safety handled, gas-line work is precise, code-governed plumbing: repairing damaged or leaking lines, running new lines for appliances, upsizing pipe for higher demand, and pressure-testing systems so the paperwork proves what the pipe holds.
Our Services
Signs You Need This Service
Signs a gas line needs professional attention (after the area is safe):
- Odorant smell. The added smell means gas where it should not be. Evacuate first, diagnose later. No exceptions.
- Hissing near gas piping. Escaping gas at fittings, valves or damaged pipe makes noise before it makes headlines.
- Appliances starving. Burners that weaken when other gas appliances run point to undersized or restricted piping.
- A failed pressure test or inspection notice. The system does not hold test pressure. The leak must be found and fixed before gas flows again.
- Utility shutoff or red tag. The utility or an inspector has flagged the system; restoration requires documented repair and retest.
- Visible damage or corrosion. Rusted, dented or unsupported exposed piping is a finding whether or not it leaks today.

Service Details & What's Included
The work this section covers:
- Gas line repair. Leaks, damaged sections and failed fittings: found, fixed and proven by retest.
- New lines and appliance connections. Runs for ranges, dryers, water heaters, fireplaces, generators and outdoor kitchens, sized for the appliance's demand, with shutoffs and flexible connectors done right. Appliance hookup itself lives under Gas Appliance Connection.
- Line sizing and upsizing. Adding load (a tankless water heater, a generator) often exceeds what the existing pipe can carry; sizing math and an upsized run come before the new appliance disappoints.
- Pressure testing and inspections. Tests for new work, remodels, real estate transactions and utility restorations, with documentation that matches local requirements.
Frequently Asked Questions
Who should I call if I smell gas?
From outside the building: 911 and your gas utility. Both are emergency responses and cost nothing. A plumber's gas work starts only after the area is declared safe; finding and repairing the leak is the second step, never the first.
Is gas-line repair different from appliance repair?
Yes. The line (piping, valves, fittings up to the appliance connection) is plumbing scope. The appliance's internals (burners, controls, ignition) belong to appliance technicians. The connection point between them is where the two scopes meet.
How is a gas problem confirmed after the area is safe?
With instruments, not noses: electronic detection sweeps, soap testing at joints, and pressure tests that prove whether the system holds. The result is a located, documented finding, not a guess.
Why can a new appliance require gas-line changes?
Because pipe is sized for total demand. A high-input appliance, commonly a tankless water heater or standby generator, can exceed the existing line's capacity, starving it and everything else. The sizing calculation decides, not optimism.
Does the utility own the gas line on my property?
Typically the utility owns up to and including the meter; everything downstream (house piping, valves, appliance runs) is the owner's responsibility. That boundary decides who repairs what and who you call first.
What is included in a gas pressure test?
The system or section is isolated, pressurized with air to the required test pressure, and watched on a calibrated gauge for the required duration. Holding means tight; dropping means a leak to find. Documentation follows local code and the reason for the test.
Gas Line Service
If you smell gas right now: leave and call 911 and the utility first. For everything else, describe the appliance, the symptom or the notice you received, and whether the utility is involved.
