Gas Line Plumbers in Austin & San Antonio

Leave. Do not switch lights on or off, do not use the phone inside, do not light anything, and do not open windows on your way out; just go, and leave the door open. From outside, call your gas utility’s emergency line or 911. They will send someone to shut off and check the service, and they do not charge for that. Do not go back in until they say it is safe. Once the utility has secured the service, call Radiant. We locate the leak, repair it, pressure-test the system and coordinate getting the gas turned back on. A faint whiff outdoors near the meter is less urgent than a smell inside, but it still deserves a call the same day.

Yes, and it is one of the more popular projects we do. We run a buried line from the house piping or the meter out to the patio, bring it up where the grill, fire feature or outdoor cooktop will sit, and install a shutoff valve there, with a quick-connect fitting if you want to be able to unhook a grill. The important parts are sizing the line so the new appliance and everything already on the system all get enough gas at once, burying it to a proper depth, and pressure-testing before it is connected. New gas piping generally needs a permit and an inspection, which we handle. Once it is done, no more hauling propane cylinders.

With a pressure test first, then detection. Isolating the buried run and watching a gauge tells us whether it is losing pressure and roughly how fast. Then we walk the line with an electronic gas detector, probing the soil along the route, and look for the signs the ground gives us: dead grass in a strip, bubbles in wet soil, or a faint smell at the surface. That narrows the leak to a spot so we can open the ground there instead of trenching the whole run. On an old line with several suspect joints, or one that has been repaired before, we may recommend replacing the run rather than chasing it leak by leak. You get both prices and our honest recommendation.

In most cities and counties around Austin and San Antonio, yes. New gas piping and meaningful changes to existing piping generally require a plumbing permit and an inspection, and the work has to be done by a licensed plumber. That is not paperwork for its own sake: the inspection confirms the system held a pressure test and was installed to standard before it is put into service, which protects you and anyone who buys the house later. Radiant pulls the permit, schedules the inspection and meets the inspector, and the cost is included in the written price. Simply replacing an appliance on an existing, unchanged line usually does not require one, and we tell you which case yours is.

Mostly what the ground does to the pipe. In San Antonio, CPS Energy owns the gas up to the meter; everything from the meter to your appliances is yours. Across the east, south and central parts of the city, expansive clay swells and shrinks with the seasons and the slab moves with it. Buried black iron from the meter riser to the house does not, so threaded joints work loose or rust through where the pipe meets the foundation. North and west, toward Helotes and Boerne, rocky caliche backfill abrades buried lines.

Gas line repair in San Antonio usually means isolating the run with a pressure test, locating the leak, replacing the failed section or rerouting it above ground, testing again and coordinating the relight. Our San Antonio plumbers handle the permit where one applies.

Once Texas Gas Service, the utility for most of the Austin area, has secured the service, the work is ours: pressure-test the system, find the leak, repair or replace the section, test again and get the appliances relit. In pier-and-beam homes in Hyde Park, Crestview and Clarksville, original black iron runs through a damp crawl space and rusts at the threaded joints. In slab homes east of I-35 and up through Pflugerville and Round Rock, Blackland clay moves the slab and stresses the line where it enters the house. Older houses also hide live soft-copper runs to long-gone floor furnaces.

Gas line repair in Austin often turns up a trunk line sized decades ago that cannot feed a new tankless heater or range. Our Austin plumbers size and quote that upfront.
