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.”

FAQ

Frequently Asked Questions

Have questions? We’ve got answers. Can’t find what you’re looking for? Give us a call anytime.

Our friendly team is available 24/7 to help you.

A tank replacement runs $1,200 to $3,500 depending on size, fuel type, and access. A tankless installation runs $2,500 to $6,500, and if the gas line needs upsizing, add $500 to $1,500. Attic installs cost more than garage installs because of the labor to get the old unit down and the new one up. We quote the number in writing before we start, access surcharge included.

Eight to twelve years for a tank. Fifteen to twenty for a tankless that gets descaled annually. North Texas water is hard enough that skipping maintenance shortens both numbers.

Usually not. That is sediment on the bottom of the tank, and water is boiling underneath it. A flush often fixes it. If the noise persists after a flush, or if the unit is already past ten years, the sediment has been cooking the tank bottom for a while and it is closer to the end than the beginning.

It depends on where it is coming from. If it is coming from a fitting, a valve, or the T&P discharge pipe, that is a repair and it can usually wait until business hours. If it is coming from the tank body itself, the tank has failed and it will get worse. If the unit is in your attic, treat that as an emergency, shut the cold water supply valve on top of the unit, and call us.

If it is in a garage and it is healthy, no rush. If it is in an attic and it is over eight years old, seriously consider it. A planned replacement costs $1,200 to $3,500. An attic tank that fails on its own costs that plus a ceiling, and the ceiling is usually the bigger number.

It depends on how long you are staying. Tankless costs roughly twice as much up front and lasts roughly twice as long, so the math only works if you are keeping the house. ENERGY STAR puts the energy savings at up to about 34 percent. If you are selling in three years, put a tank in and keep the difference. If you are staying fifteen years and you have gas capacity, tankless is worth a real conversation.

Once a year for a tank, once a year for a tankless descale. North Texas water leaves scale, and on a tankless unit the scale collects directly on the heat exchanger, which is the expensive part. Annual descaling is not upselling. It is the difference between a unit that lasts eighteen years and one that lasts eight.

Usually a spent anode rod. The anode is a sacrificial metal rod inside the tank that corrodes so the tank does not. When it is used up, the tank starts corroding instead. If we catch it in time, replacing the rod buys you years. If the tank is already rusting through, it is too late for the rod.

Most often a failing thermocouple, which is a cheap part. But if the pilot outage comes with soot around the unit, a burnt smell, or a yellow flame instead of blue, stop. That is a combustion or venting problem, not a pilot problem, and a gas appliance that is not venting correctly puts carbon monoxide in your house. Call us and get a CO detector in the meantime.

Yes. Water heater replacement is permitted work in Plano and in every surrounding city. We pull it. An unpermitted install can cause you problems at resale and it can void the manufacturer warranty. If a contractor offers to skip the permit to save you money, that is a contractor telling you something about himself.

If you call before noon on a weekday, usually yes. We are not a 24-hour company. After-hours and weekend calls carry a flat $199 dispatch fee, quoted before we come.

No. The federal 25C energy efficiency tax credit ended December 31, 2025. Any contractor still quoting you a federal credit on a 2026 install is working from outdated information. Check with your utility about local rebates, which are separate and may still exist.

Our friendly team is available 24/7 to help you.

Comparison

Repair or Replace: How We Actually Decide

We do not sell tanks for a living. We fix things. Here is the honest framework.

SituationOur recommendationWhy
Unit under 8 years, no hot waterRepairUsually a thermocouple, heating element, or thermostat. A few hundred dollars on a unit with years left.
Unit under 8 years, pilot will not stay litRepairThermocouple or gas valve. Not a tank problem.
Rumbling or popping noise, unit otherwise fineFlush first, then decideThat is sediment boiling under the burner. A flush often fixes it.
Rusty or brown hot waterCheck the anode rodIf the anode is spent but the tank is still sound, replacing the rod can add years. If the tank is already rusting through, it is done.
Water leaking from the tank body itselfReplace. Immediately.A tank leaking from the body is failing. There is no repair. It will get worse, not better.
Water leaking from a fitting or valveRepairThat is a connection, not the tank.
Unit over 12 years, needing a second repairReplaceYou are throwing money at a unit that is already past its expected life.
Unit over 8 years in an atticLean replaceThe downside risk of a failure is your ceiling. The math is different up there.
Pilot outage plus a burnt smell or sootStop. Call us.That is a combustion problem, not a hot water problem. See the safety section below.
Not enough hot water, unit healthyResize, do not replaceYou may have outgrown the tank. That is a sizing conversation, not a repair.

If a $250 part will get you five more good years, we will tell you to buy the part.

Tank or Tankless: The Honest Comparison

Tankless is not automatically better. It is better for some houses and a waste of money in others.

 TankTankless
Install cost$1,200 to $3,500$2,500 to $6,500
Expected life8 to 12 years15 to 20 years
Hot water supplyLimited to tank capacityContinuous
RecoveryRuns out, then refills slowlyNo recovery period
Energy useStandby loss (it heats water all day whether you use it or not)Heats only on demand. ENERGY STAR puts savings at up to about 34 percent.
SpaceTakes a closet or an attic footprintWall-mounted, compact
Gas lineUsually fine as-isOften needs upsizing. $500 to $1,500.
VentingStandard flueUsually needs new stainless or PVC venting
MaintenanceAnnual flushAnnual descale, and it is not optional in North Texas
Failure modeCan dump its whole volumeNo stored volume to dump
Best forSteady predictable demand, budget-first replacement, garage installsHigh simultaneous demand, long-term ownership, attic installs where stored volume is a liability

The honest read: if you are replacing a failed unit tomorrow and you plan to sell the house in three years, put a tank in. If you are staying fifteen years, have gas capacity, and the unit is in the attic, tankless is worth the conversation.

We will not push you toward the more expensive one. We install both.
