Gas Line Installation & Repair in Alpharetta, GA
Gas leak repair, outdoor kitchen and grill hookups, gas water heater and tankless supply, stove and dryer connections, CSST flex installation, pressure testing. Permitted work, code-compliant joints, leak-tested before service.
Gas line work is the area where doing it right matters most. A bad water connection drips; a bad gas connection can kill someone. We pull permits on gas line work, pressure-test every connection before putting it into service, and only run flex appropriate for the application. If you have a gas smell, the call comes first — before any DIY troubleshooting.

Gas line work — what's in scope
New gas line installation. Adding a gas supply where there isn't one — typical jobs: running a line to an outdoor kitchen, adding a grill hookup, extending to a new gas dryer location, supplying a new tankless water heater. Sizing the line, running it on appropriate hangers, terminating with a shutoff valve, pressure testing.
Gas line repair. Fixing a leak in an existing line. Most residential leaks are at fittings — flare joints, threaded connections — rather than mid-run in the pipe. Repair typically replaces the affected fitting and pressure-tests the line.
Gas appliance hookups. Connecting gas stoves, dryers, water heaters, tankless heaters, fireplace inserts, generators, and pool heaters. Each has specific connector and shutoff valve requirements.
Gas line upgrades for tankless water heaters. Existing line supplies 40,000 BTU water heater; new tankless demands 199,000 BTU. Often requires upsizing the line from the meter to the unit — see tankless service page.
CSST (corrugated stainless steel tubing) installation. The yellow flexible gas tubing common in new construction. Requires specific fittings, proper bonding to the home's electrical ground (a critical safety requirement), and specific testing procedures.
Gas line pressure testing. Required at install and after repair. Pressurize the system above operating pressure, monitor for pressure drop, confirm tight before restoring service.
Gas leak diagnosis — what we do, what to do first
If you smell gas inside your home: get everyone out of the house first, then call from outside. Don't switch lights on or off (a switch arc can ignite gas). Don't use a phone inside the house. Don't restart any appliance that might have caused the leak.
Once safely outside, call us and call the gas utility's emergency line. The utility's first response is to shut off your gas service from the meter; our work begins after the immediate hazard is controlled.
For non-emergency suspected leaks (the slight gas smell that goes away, a slight bill increase, a hiss near a fitting): we come out and locate the leak with electronic gas detection equipment, then quote the repair. Common locations: stove flex line at the wall connection, dryer connection, water heater connection, exterior service line where it enters the house.
For repairs we always pressure-test after the work. The home isn't put back into service until the test is passed and documented.
Permits, code, and what we won't do
Gas line work in Alpharetta requires a plumbing permit and an inspection. We pull the permit and coordinate the inspection. Permit fees are passed through at cost.
What we install: schedule 40 black iron pipe for hard-piped runs, CSST for flex connections, brass shutoff valves at every appliance, flare or compression connections at flex-to-rigid transitions, drip legs where required.
What we don't do: connect a gas line to an appliance we have safety concerns about. Run flex through walls (CSST inside walls requires specific protection and bonding; we don't shortcut this). Approve or sign off on third-party gas work without our own pressure test. Continue to work in a space with an active gas smell.
For outdoor kitchen and grill hookups, the run typically starts at an interior gas tap, exits the wall through a sleeved penetration, runs underground to the grill location, and terminates with a quarter-turn shutoff. We coordinate with masonry contractors on outdoor kitchen builds so the gas penetrations line up with the planned masonry openings.
Avalon, Halcyon, and Windward — common gas line calls
Newer Alpharetta developments — Avalon, Halcyon, newer sections of Windward — generate a steady stream of gas line additions. Common requests: outdoor kitchen gas, fire pit gas, pool heater gas, secondary grill hookups on patios. CSST is standard in this newer construction; existing taps inside the wall are typically available, and the work is mostly extending from the tap to the new appliance location.
Older Alpharetta homes (Crabapple, Old Alpharetta, Old Milton) more often see gas line repair than installation. Older black iron lines develop corrosion at threaded joints over decades. Where multiple joints are affected, we sometimes recommend replacing the run rather than chasing leaks fitting by fitting.
For new construction or major renovation, we coordinate with the GC on gas line layout during framing so penetrations are placed cleanly and appliance shutoffs are in accessible locations.

Frequently asked
I smell gas. What do I do?
Get everyone out of the house first. Don't switch lights, don't use phones inside, don't restart appliances. Once outside, call the gas utility's emergency line and then call us. The utility shuts off service at the meter; we handle the repair after the hazard is controlled.
Do I need a permit for a gas line addition?
Yes — Alpharetta requires a plumbing permit for gas line installation. We pull the permit, coordinate the inspection, and pass permit fees through at cost.
Can you hook up my gas grill?
Yes — running a gas line from an existing interior tap (or from the meter if no interior tap is available) to an exterior grill location, terminating with a quarter-turn shutoff valve and a connection appropriate for your specific grill. Same scope for outdoor kitchen ranges, fire pits, and patio heaters.
Do I need to upgrade my gas line for a tankless water heater?
Maybe — depends on existing line size and length from the meter. A 199,000 BTU tankless demands much more gas volume than the 40,000 BTU water heater it's replacing. We measure existing line capacity on the quote visit and tell you honestly whether the line will support the new unit.
What's CSST and why does it need to be bonded?
CSST is the yellow flexible gas tubing common in newer construction. It must be electrically bonded to the home's grounding system because lightning strikes can cause arc-through-CSST events that ignite gas — bonding gives the energy a safer path to ground. Bonding is a code requirement; we always include it on CSST installs.
