About James Armstrong Plumbing
Meet the Master Plumber Serving DFW: James Armstrong
James Armstrong is a Texas Master Plumber, License M-39428, with a gas endorsement. He has worked plumbing in east Dallas County since 1995, and he still runs the jobs.
Master Plumber is the highest plumbing credential the State of Texas issues. It requires years of documented field experience under a licensed plumber, passing the state examination, and maintaining the license in good standing with the Texas State Board of Plumbing Examiners. Certain work, including all gas line work, legally requires it. You can verify any Texas plumbing license for free on the state board’s website, and we would encourage you to.
The gas endorsement is separate and additional. It is what allows us to install, repair, and test gas piping rather than referring that work out.
