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.”

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. A 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 have to reach it. We quote a flat rate once we have looked at the job, not before.
Our shop is in Mesquite, about fifteen minutes from most of Rowlett. If you call before noon on a weekday we can usually be there the same day. That is not a marketing promise, it is just how far away we are.
Usually a slab leak, which is a hot water line failing under the foundation. The clay soil under Rowlett swells and shrinks with the weather, the slab moves with it, and the copper underneath eventually 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 in North Texas.
No. We are Monday through Friday, 8:00 AM to 5:00 PM, and if you call before noon we can usually be there the same day. After hours and weekends carry a flat $199 dispatch fee, quoted on the phone before anyone gets in a truck. And if your problem can wait until morning, we will tell you that and save you the money.
Almost never. It is nearly always the flapper, the rubber disc at the bottom of the tank, and that is a $15 part and a ten minute job with no tools. Here is a free way to confirm it: put a few drops of food coloring in the tank, do not flush, and wait twenty minutes. If color shows up in the bowl, the flapper is leaking. A running toilet wastes over 200 gallons a day, so if yours has been going six months you have already paid for that part many times over on your water bill.
Yes, and there is something worth doing this week. Check that there is a drain pan under the tank, check that the pan has a drain line that actually runs to the outside of the house rather than just ending in the attic, and put a $15 battery water alarm in the pan. A 50 gallon tank failing in a garage is a wet floor. The same tank failing in an attic sends fifty gallons through your ceiling.
Run the meter test. Turn off every faucet, appliance, ice maker, and irrigation zone, then go look at your water meter and find the small triangle or dial that spins when water is moving. If it is moving with nothing running, water is going somewhere. One caveat: a leaking toilet will trip this test, so 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 rather than a slab leak.
If one sink or tub is slow and everything else works fine, 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 your main line. If it is the main line, stop running water anywhere in the house, because everything you send down is coming back up.
Either in the garage where the water line comes into the house, or in a rectangular box in the ground near the curb marked WATER. Go find it today, turn it off, and turn it back on. You learn where it is, and you find out whether it still works, because old valves seize and a valve that will not close is how a small leak becomes a flooded house. A meter key for the street box is about $15.
Almost always a garden hose left connected over the winter. The hose traps water inside the valve, it freezes, and it splits the valve body. You often do not find out until spring, when you turn it on and the water comes out inside your wall instead of the yard. It is a $250 to $500 repair, and disconnecting your hoses in November prevents it entirely.
Most of Rowlett went up between the 1980s and 2000s, so the pipe is generally copper and PVC rather than the cast iron and galvanized found in older cities. But a 1990s house is thirty years old now, 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, and original shutoff valves that have seized and will not close.
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.
Leave the building. Do not flip a switch, unplug anything, or use your phone inside, because any spark can ignite it. Get everyone and any 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.

|---|---|---|
| Warm spot on the floor | Slab leak. A hot line under the foundation. | $1,500 to $15,000 |
| Water bill jumped and nothing changed | Slab leak, or a running toilet. Check the toilets first. | $15 to $15,000 |
| You hear water running with everything off | A leak somewhere. Possibly under the slab. | Locate first |
| New cracks in the slab or drywall | Possible slab leak. Worth looking. | Locate first |
| Low pressure at one faucet | The aerator. Unscrew it and rinse it. | Free |
| Low pressure everywhere | Pressure regulator, or the supply line. | $350 and up |
| Toilet running constantly | The flapper. A $15 part. | $15 to $250 |
| One drain slow, everything else fine | That fixture. | $150 to $350 |
| Multiple drains backing up | Main line. Stop using water in the house. | $250 to $600+ |

| Gas smell | Leave the house. Call 911 and Atmos, 866-322-8667. | Utility first, free |
The first row is the one to pay attention to. In North Texas, a warm patch on the floor is the most commonly overlooked serious plumbing symptom there is. People walk across it for a year. The clay soil under Rowlett swells and shrinks with the weather, the slab moves with it, and eventually a copper hot line running underneath rubs through. If you have one, it is worth a phone call.
