Gas Line Plumbing in McKinney, TX
James Armstrong Plumbing installs, replaces, and tests gas lines in McKinney, TX. Master Plumber James Armstrong holds Texas License M-39428 with a gas endorsement, which not every master plumber carries.
Gas piping in Texas has to be installed by a licensed plumber under Texas Occupations Code Chapter 1301 and built to NFPA 54, the National Fuel Gas Code. We pull the McKinney permit, pressure test the system, and stay for the inspection.
We run out of our shop at 844 Dalworth Dr in Mesquite, about 40 minutes from McKinney. Gas line work is planned, permitted, scheduled work, so the distance costs you nothing.
We do not take emergency gas leak calls in McKinney.

Meet James Armstrong
Meet the Master Plumber Serving DFW: James Armstrong
James Armstrong has been a Mesquite-resident Master Plumber since 1995. What began as helping neighbors fix leaky faucets turned into a career — and eventually a family business, built on one simple rule: treat people right, do the job with integrity, and always stand behind your work. Today, James and his crew serve Mesquite, McKinney, Sachse, Garland, and the broader DFW metro from the Mesquite headquarters at 844 Dalworth Dr.
“In thirty years of plumbing across the DFW metro, including McKinney, the drain calls almost always come down to two things: tree roots in the older neighborhoods, and grease and hair buildup in the newer developments. We camera-inspect first, then choose hydro-jetting or snaking based on what we actually see — not on what gets you to the highest invoice.”

Leave the building immediately with everyone and every pet. Do not touch light switches, appliances, or any phone inside, and do not start a vehicle in the garage. Do not open or close any gas valve. From a safe distance outside, call 911, then call your gas utility. Most of McKinney is served by Atmos Energy at 866-322-8667, and parts of Collin County are served by CoServ Gas at 844-330-0763. Check your gas bill if you are unsure. Do not go back inside until the utility or the fire department says it is safe, and call a plumber only after that.
Yes, for planned and permitted work. New gas line runs, gas line replacement, appliance additions, pressure testing, and inspection-report items are all scheduled jobs we take in McKinney from our Mesquite shop about 40 minutes away. We do not take emergency gas leak calls in McKinney. Your gas utility can shut the gas at the meter far faster than we can get there, and that is the right call.
Gas piping must be installed by a licensed plumber under Texas Occupations Code Chapter 1301, and not every master plumber carries the gas endorsement. James Armstrong holds Texas License M-39428 with the gas endorsement, and gas piping is installed to NFPA 54, the National Fuel Gas Code. Ask any contractor for their license number and check it before gas work starts.
CSST is the flexible yellow gas tubing common in homes built after about 2000. Its walls are thin enough that a nearby lightning strike can arc through and perforate them if the gas piping system is not properly bonded to the electrical grounding system. The fuel gas codes have required bonding since the 2009 editions, using a jumper no smaller than 6 AWG copper connected to metal, not to the plastic jacket. It is the most commonly flagged gas item on DFW inspection reports.
Yes. Gas line work in McKinney requires a permit through the Citizen Self-Service portal, and the system is pressure tested and inspected before it goes into service. We pull the permit as part of the job. Confirm current requirements with City of McKinney Building Inspections at 469-617-4800.
Usually, but the question is load rather than the line by itself. Every gas appliance draws from the same service, so before adding anything we check whether the existing piping and the meter can carry the total with everything running. Sometimes that means a larger line, a dedicated run, or a meter upgrade request to the utility.
Yes. Texas law requires calling 811 at least two business days before any digging so utility-owned lines get located and marked. The call is free, and failure to call is the leading cause of pipeline damage in the state. We handle this on jobs we run.
It depends on what your house needs. The gas piping side is plumbing work. The bonding conductor terminates on the electrical service grounding electrode system, so part of the correction may belong to a licensed electrician. We assess it and tell you which parts are ours and which are not, in writing, before anything starts.
