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, Rowlett, Sachse, Garland, and the broader east DFW metro, with most calls dispatched and on-site within 25 minutes of the Mesquite headquarters at 844 Dalworth Dr.
“In thirty years working Rowlett, Garland, and the Lake Ray Hubbard side of the metro, the drain calls almost always come down to two things: tree roots in the older Rowlett neighborhoods near the lake, and grease and hair buildup in the newer developments off Liberty Grove and Schrade Road. 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.”

A leak sensor detects water and alerts you. An automatic shutoff valve installs on your main line, monitors flow and pressure, and closes the water when it detects a leak. The sensor tells you about damage. The valve stops it. Sensors are inexpensive and you can place them yourself. A shutoff valve cuts into the main supply line and is licensed plumbing work.
Yes. The valve installs on the main water line where it enters the house, which means cutting into the supply and making permanent connections. That is licensed plumbing work in Texas. Master Plumber James Armstrong, License M-39428, oversees every installation we do.
It can, and this is the strongest argument for one in North Texas. A supply line failure under a slab is invisible from inside the house and runs continuously, often for weeks. A shutoff system monitoring flow can identify continuous flow that should not be happening and close the valve, which shortens the exposure dramatically compared to waiting for a water bill or a warm spot on the floor.
Many carriers offer a discount for one, and some require documentation of a professional installation to qualify. Policies vary, so ask your carrier what they offer and what they need before you buy. We provide installation documentation for the claim.
The highest-value spots are beside the water heater, under kitchen and bathroom sinks, behind the washing machine, under the dishwasher, at the base of each toilet, and near the main shutoff. Those cover the failures that account for most household water damage.
