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.”

Frequently Asked Questions

Most repairs run $150 to $600. A toilet or faucet repair is $150 to $400. A drain clearing is $150 to $350, and a main line clearing is $250 to $600. Water heater replacement is $1,200 to $3,500. A slab leak is $1,500 to $15,000 depending on where it is and how we reach it. We quote a flat rate once we have looked at the job, not before.
Usually a slab leak, which is a hot water line failing under the foundation. North Texas clay swells and shrinks with the weather, the slab moves, and the copper underneath moves with it until something rubs through. Other signs are a water bill that jumped and stayed up, the sound of running water when everything is off, and new cracks in the slab or drywall. It is the most commonly overlooked serious plumbing symptom around here.
No. We are Monday through Friday, 8:00 AM to 5:00 PM, and if you call before noon we can usually get out the same day. After hours and weekends carry a flat $199 dispatch fee, quoted on the phone before anyone gets in a truck. If what you have can wait until morning, we will tell you so and save you the money.
Run the meter test. Turn off every faucet, appliance, ice maker, and irrigation zone, then look at the water meter and find the small triangle or dial that spins when water moves. If it is moving with nothing running, water is going somewhere. One caveat: a leaking toilet trips this test. Put food coloring in each tank, wait twenty minutes without flushing, and if color appears in a bowl, that is your answer and it is a $15 flapper.
If one sink or tub is slow and everything else works, it is that fixture. If the toilet backs up when the washing machine drains, if the tub gurgles when you flush, or if more than one fixture is backing up, the problem is in the main line. If it is the main line, stop running water anywhere in the house, because everything you send down is coming back up.
More than most people realize. A 50 gallon tank failing in a garage is a wet floor. The same tank failing in an attic sends fifty gallons through the ceiling. Go up and check that there is a drain pan under it, that the pan has a drain line that actually runs to the outside of the house rather than just ending in the attic, and drop a $15 battery water alarm in the pan. It is the best fifteen dollars in home ownership.
Much of Plano went up in the 1980s and 1990s, so the pipe is generally copper and PVC rather than the cast iron and galvanized found in older cities. But that housing stock is now 30 to 40 years old, and a few things come due at that age: slab leaks from the clay soil moving, water heaters at the end of their 8 to 12 year run, original shutoff valves that have seized, and in some houses polybutylene supply pipe.
Gray or blue plastic supply pipe used in a lot of houses built roughly between 1978 and 1995. Chlorine in municipal water degrades it from the inside and it tends to fail without warning. The part most homeowners do not know is that many insurance carriers will not write a policy on a house that still has it, or will write it with a water damage exclusion. It usually shows up near the water heater or under sinks.
Yes. Cities require permits and inspections for water heaters, gas work, repiping, and sewer repair. A lot of the market skips it because a permit means an inspector shows up and looks at the work. It becomes a problem later, when you sell the house and the buyer's inspector finds it. We pull them, itemize them separately, and do not mark them up.
Yes. Single-family homes, condos, townhomes, HOA-managed properties, and light commercial including offices, retail, clinics, restaurants, and multi-unit residential. Condo and HOA work has its own wrinkles around access windows, shared stacks, and who is responsible for which side of the wall, and we are glad to talk through that.
We are in Mesquite, about 25 miles from Plano, and we would rather say that plainly than pretend otherwise. We are happy to make the drive. If a pipe has burst and your house is filling with water, call whoever can get there fastest.
Leave the building. Do not flip a switch, unplug anything, or use your phone inside, because any spark can ignite it. Get people and pets out and leave the door open behind you. From a safe distance outside, call 911 and Atmos Energy at 866-322-8667. Atmos runs a 24 hour line and will come shut the gas off at no charge. Call us afterward at 214-918-6109 for the repair.
