Meet James Armstrong
Meet the Master Plumber Serving Mesquite: James Armstrong
James Armstrong started installing and repairing water heaters in Mesquite, TX in 1995. He holds a Texas Master Plumber License (M-39428) and runs James Armstrong Plumbing out of our shop at 844 Dalworth Dr., Suite 10, in Mesquite.
30+ years of installing water heaters in this metro means James has seen every common failure mode — sediment cooked onto burners, anode rods depleted to bare wire, thermostats wired wrong by the previous installer, gas line capacity too small for tankless conversions, pressure-relief valves that should have been replaced years ago. The crew trains on every system, and James personally reviews every installation quote before it goes out the door.
“If your water heater is under 8 years old and it’s a single component that failed — thermostat, element, gas valve — repair almost always makes sense. If it’s over 10 and the tank is leaking, replacement is the only answer. The hard call is the 8-to-10-year window. There I look at maintenance history, water hardness damage, and whether the repair cost is approaching half the price of a new install. We quote both options when both are viable.”

Both Repair and Replacement Quoted, When Both Make Sense

Flat-Rate Quoted on Arrival
Every quote is flat-rate, written, and confirmed before any work starts. The number on the quote is the number on the invoice. No "the install turned out worse than we thought" surprises mid-job.

The Armstrong Clean Promise
Marked trucks, floor protection on every job, and the worksite cleaner than we found it. Water heater installs can be a messy job — drained tanks, old sediment, removed venting. The crew brings drop cloths, towels, and shop vacs. We always make sure the install area is back to normal before we leave.

Traditional tank water heaters in Mesquite typically last 8 to 12 years. Tankless units last 15 to 20 years. Mesquite is part of the moderately hard water region of DFW (roughly 7-12 grains per gallon), and sediment buildup from hard water is the single biggest factor that shortens water heater life. Annual sediment flushing extends both tank and tankless lifespan significantly.
Repair is usually the right call for units under 8 years old with isolated component failures (thermostat, heating element, gas valve, pressure-relief valve). Replacement is usually the right call when the tank itself is leaking, the unit is over 10 years old, or repair cost exceeds half the price of a new unit. Master Plumber James Armstrong (Texas License M-39428) personally reviews every diagnosis and quotes both options when both are viable.
It depends on the home. Tankless makes sense for households with high hot water demand, homes with limited utility space, or owners planning to stay 10+ years (the longer lifespan recoups the higher install cost). Tank water heaters make sense for smaller households, tighter budgets, or homes where gas line capacity is the limiting factor. We assess your home's hot water demand, gas line capacity, and venting before we recommend either.
Water heater installation pricing depends on the unit type (tank vs tankless), fuel source (gas vs electric), capacity, and whether your home needs gas line, venting, or electrical upgrades. We quote flat-rate after an in-home inspection — the number on the quote is the number on the invoice, with no surprise charges mid-install. Call 214-918-6109 to schedule a free in-home quote.
Yes. We respond to tank leaks, supply line failures, pressure-relief valve discharges, and total unit failures. Most Mesquite-proper emergency calls are reached within 30 minutes from our shop at 844 Dalworth Dr., Suite 10. After-hours calls are accepted — call 214-918-6109 to confirm current availability. Owner James Armstrong (Texas Master Plumber License M-39428) personally oversees every emergency response.
We install Bradford White, Rheem, A.O. Smith, Navien (tankless), Rinnai (tankless), and other trusted brands available through our supply partners — Ferguson, Apex Plumbing Supply, and Home Depot. We recommend the brand and model based on your hot water demand, home configuration, and warranty preferences, not based on what gets us a bigger margin.
Comparison
Tank vs Tankless Water Heaters: Which Makes Sense for Your Mesquite Home?
Consideration | Tank Water Heater | Tankless Water Heater |
Upfront install cost | Lower | Higher |
Typical lifespan | 8-12 years | 15-20 years |
Energy efficiency | Lower — keeps tank hot 24/7 | Higher — heats only on demand |
Space required | Full utility closet | Wall-mounted, compact |
Hot water supply | Limited by tank size — runs out | Endless — heats as you use it |
Mesquite hard water impact | Sediment buildup shortens tank life | Scale buildup on heat exchanger — needs annual descaling |
Gas line / electrical requirements | Usually fits existing infrastructure | May require gas line upsize or electrical upgrade |
Best for | Smaller households, tighter budgets, faster install | Larger households, long-term owners, limited utility space |
Comparison
Repair or Replace? A Quick Decision Guide
Situation | Usual Recommendation |
Unit under 8 years, isolated component failure (thermostat, element, gas valve) | Repair — component swap is almost always the right call here. |
Unit 8-10 years, isolated component failure | Case by case — look at maintenance history, hard water damage, and whether repair cost is approaching half a new install. |
Unit over 10 years, any failure | Replace — repairing past 10 years usually buys 12-18 months at most before something else fails. |
Tank itself is leaking (water around tank base from the tank, not fittings) | Replace — tank corrosion is terminal regardless of age. Patching is not a real fix. |
Repair cost approaching half the price of a new install | Replace — at that cost ratio you’re better off with new equipment and full warranty. |
