Meet James Armstrong

Meet the Master Plumber Serving Dallas: James Armstrong

James Armstrong started in plumbing in Mesquite, TX in 1995 as an apprentice, then as a Journeyman, and since the early 2000s as a Texas Master Plumber. He runs James Armstrong Plumbing from our shop at 844 Dalworth Dr., Suite 10 in Mesquite. Same shop, same address, since 1995.

“The Dallas fixture calls that go sideways for other plumbers are the ones where somebody quoted a full valve replacement when a cartridge swap would have held for another 10 years. Or the opposite: cartridge rebuild on a valve body that was already corroded, so the customer called back three months later for the same drip. In a 1930s Munger Place home with original galvanized supply, real diagnosis means looking at the whole system, not just the fixture. The quote after honest evaluation is the number that shows up on the invoice.”

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

Fixture-level plumbing repair and installation in Dallas: faucets, sinks, shower and tub valves, shut-off valves (angle stops), pressure reducing valves, short supply line runs, garbage disposals, and hose bibs. For toilets, we have a dedicated Dallas toilet page. For water heaters, a dedicated Dallas water heater page. For sewer line and drain cleaning, dedicated Dallas pages for each. For full re-piping, a dedicated pipe leak repair and re-piping page. Call 214-918-6109 if you're unsure which service applies.

Fixture and valve repair pricing depends on the specific fixture (faucet cartridge repair versus full faucet replacement versus valve body swap), accessibility (some shower valve replacements in historic East Dallas homes require plaster or drywall access), and whether related components (supply lines, angle stops) need replacement while we're already in the wall. We diagnose on-site and quote flat-rate before any work begins. The number on the quote is the number on the invoice.

Repair if the faucet is under 10 years old, the finish is intact, the cartridge type is still manufactured, and the fixture matches your kitchen or bath design. Replace if the faucet is 15+ years old (typical Dallas Water Utilities hard water lifespan), the finish is pitted or discolored, the cartridge type has been discontinued (common on older Delta, Moen, and Kohler models), or the fixture doesn't match your current design. On-site diagnosis gives a specific answer for your fixture. We bring the cartridge type reference and can tell you within a few minutes whether repair parts are still available.

Pre-1960 East Dallas homes were commonly built with galvanized steel supply lines. Galvanized corrodes from the inside out over decades. The corrosion affects the shut-off valves connected to those supply lines: rust and scale seize the valves so they will not close when you need them, and mineral debris flakes into faucet cartridges and PRV bodies downstream. Once one angle stop fails in a galvanized-supply home, the others are usually not far behind. We replace corroded angle stops with quarter-turn ball valves that seal reliably on the first use and will last decades.

Yes. Hose bib replacement is one of the most common repair calls we get after winter cold snaps. Standard hose bibs freeze and split at the valve seat when temperatures drop below 20°F, especially in Dallas homes with uninsulated outdoor plumbing. When we replace a frozen hose bib, we usually recommend upgrading to a frost-free hose bib. The valve body sits inside the house wall where it stays above freezing, dramatically reducing repeat freeze failures. Frost-free installation is more involved (requires access to the interior side) but the once-and-done nature saves repeat calls.

Our shop is at 844 Dalworth Dr., Suite 10 in Mesquite. Most East Dallas calls are reached within 25 to 40 minutes from dispatch during business hours, longer overnight and on weekends. Active plumbing emergencies (burst pipes, active leaks) are prioritized and typically dispatched same-day when reported before noon Monday through Friday. After-hours, weekend, and holiday calls accepted. Call 214-918-6109 to confirm current availability.

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

Comparison

Repair or Replace? Fixture Decision Matrix

Both options quoted flat-rate before any work begins. If a repair will hold for reasonable service life, we quote the repair. If the fixture has aged past reliable repair, we say so honestly.

FixtureRepairReplace
Faucet (under 10 yrs, cartridge available)Yes, cartridge repair or rebuild. Same-day, minimal disruption.Only if finish is worn or you’re changing kitchen/bath design
Faucet (15+ yrs or cartridge discontinued)Not recommended, parts unavailable, wear on other componentsYes, full faucet replacement is cheaper than sourcing discontinued parts
Shut-off valve (angle stop)NEVER repair. Compression valves don’t have serviceable parts.Always replace with quarter-turn ball valve. Reliable seal for decades.
Shower/tub cartridge (valve body sound)Yes, cartridge swap. Verify cartridge is still manufactured.Only if cartridge is discontinued or valve body shows corrosion
Shower/tub valve body (corroded or discontinued cartridge)Not recommended, false economy given re-work riskYes, full valve body replacement. Requires drywall or plaster access.
PRV (Pressure Reducing Valve)Sometimes, diaphragm rebuild for late-model units. Older units: replace.Yes when 15+ yrs old, corroded body, or pressure won’t stabilize after repair
Braided supply line (visible corrosion or age 8+ yrs)Never repair braided lines, replace the whole lineAlways replace. New braided supply is $5-15 in parts, minutes to install.
Garbage disposal (motor works, jam only)Yes, clear jam, replace splash guard if wornOnly if motor has failed or unit is 10+ yrs old
Garbage disposal (motor failed or mounting corroded)Motor repair almost never cost-effectiveYes, full replacement. Standard 1/3 to 3/4 HP install.
Standard hose bib (winter freeze damage)Sometimes, vacuum breaker only if the valve seat is intactYes, replace with frost-free hose bib to prevent recurring freeze failures
