Meet James Armstrong
Meet the Master Plumber Serving Mesquite: James Armstrong
James Armstrong started working gas lines in Mesquite, TX in 1995 — as an apprentice under a Master Plumber, then as a Journeyman, and since 2003 as a Texas Master Plumber (License M-39428). He runs James Armstrong Plumbing from our shop at 844 Dalworth Dr., Suite 10, in Mesquite — the same address for 30+ years.
Gas work is the one plumbing service where the consequences of getting it wrong are catastrophic. Most plumbing mistakes leak water; gas leaks leak fire. That difference is why Texas regulates gas work under a Master Plumber license, and why every gas job at James Armstrong Plumbing is supervised under James’s M-license, pressure-tested per Texas code, and permitted through the City of Mesquite where required.
“In 30+ years of gas line work across east DFW, we’ve never had a code violation flagged on inspection. That’s not luck — it’s that gas work happens under a Master Plumber’s license for a reason, and we treat every job that way. Pressure-test, document, inspect, sign off. If a city inspector finds something we missed, we own it. They haven’t.”
James Armstrong, Master Plumber • Texas License M-39428 • Founder, James Armstrong Plumbing
30+ years of east DFW gas work means James has seen every era of residential gas infrastructure — black iron from the older Mesquite homes, the CSST (corrugated stainless steel tubing) of newer subdivisions, the polyethylene service lines into the meter from the gas main. The crew is trained on every system, and James personally reviews every gas line quote and signs off on every pressure-test result.
James Armstrong Plumbing is BBB A+ accredited since 2018 and a Mesquite Chamber of Commerce member. Family-owned, operating from the same Mesquite shop since 1995.

Gas Line Leak Detection

Leave the house immediately with everyone inside, including pets. Do not turn light switches on or off, do not unplug or plug in anything, do not start a vehicle in an attached garage, and do not use a phone inside the home. Once you are a safe distance from the property, call 911 first, then call Atmos Energy's 24-hour emergency line at 866-322-8667. After the gas company has confirmed and stabilized the situation, call James Armstrong Plumbing at 214-918-6109 for licensed inspection and repair. Owner James Armstrong (Texas Master Plumber License M-39428) personally oversees every emergency gas response.
Texas regulates gas work under the Texas State Board of Plumbing Examiners (TSBPE). State rules require a Master Plumber license — or a Journeyman Plumber with a Plumbing Inspector / Gas endorsement — to install, repair, or modify gas lines. A general plumber without the Master license is not legally authorized to perform gas work in Texas. James Armstrong holds a Texas Master Plumber License (M-39428) and personally supervises every gas line job at James Armstrong Plumbing.
The clearest signs are: a sulfur or rotten egg smell near appliances or in the yard, hissing sounds near gas connections, dead or dying vegetation in a line over a buried gas line, an unexplained increase in your gas bill, a weak or yellow flame on a gas stove or appliance that should burn blue, and physical symptoms like headache or nausea when indoors that improve when you leave. If you see any of these in your Mesquite home, leave the house and call 214-918-6109 from outside for a licensed inspection.
Yes. New gas line installations and most gas line modifications in Mesquite require a permit and inspection by the City of Mesquite. James Armstrong Plumbing pulls the permit, completes the work to Texas code, pressure-tests the line, and coordinates the city inspection on every gas installation. The line is not returned to service until the inspection passes.
Gas line repair pricing depends on the location of the leak or damage, line length affected, whether the line is buried (underground excavation adds cost), and whether code-required upgrades trigger during the repair. We diagnose first with pressure testing and electronic leak detection, then quote flat-rate before any work begins. The number on the quote is the number on the invoice — no surprise charges mid-repair. Call 214-918-6109 to schedule a licensed inspection.
Yes. We respond to suspected gas leaks, damaged lines, post-incident inspections, and emergency appliance disconnections. From our shop at 844 Dalworth Dr., Mesquite-proper calls are typically reached within 30 minutes from dispatch. After-hours, weekend, and holiday calls are accepted. For an active gas leak, the official protocol is: leave the house, call 911 first, then call Atmos Energy at 866-322-8667. Once the gas company has confirmed and stabilized the situation, call James Armstrong Plumbing at 214-918-6109 for licensed inspection and repair. Owner James Armstrong (Texas Master Plumber License M-39428) personally oversees every emergency gas response.
