James Armstrong Plumbing repipes McKinney homes running failing polybutylene, galvanized steel, or worn-out copper supply lines.

We pull the McKinney permit as part of the job.
We run out of our shop at 844 Dalworth Dr in Mesquite, about 40 minutes from McKinney. A repipe is planned work with a scheduled start date, which is exactly the kind of job that distance does not hurt. If what you have is one small active drip, call a plumber closer to you. We would rather tell you that than have you wait.

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.
“When somebody calls me about their third leak in a year, that is not three plumbing problems. That is one plumbing system telling you it is finished. Out here I see a lot of gray poly in the houses that went up in the eighties and early nineties, and that pipe was never going to make it to fifty years sitting in treated water. The right answer is to walk the whole system, tell the homeowner honestly whether they have a bad spot or a bad system, and quote the real number before anybody opens a wall.”

Frequently Asked Questions

Yes. Repiping is scheduled work with a set start date, which is exactly the kind of job we take in McKinney from our Mesquite shop about 40 minutes away. What we do not take in McKinney is emergency dispatch on a small active leak. For that, call a plumber based closer to you rather than waiting on a truck coming up 75.
Polybutylene was installed between 1978 and 1995 and is almost always gray flexible plastic in DFW homes. Check at the water heater, under sinks, and near the water meter. Do not confuse it with PEX, which is a modern approved material and usually red, blue, or white. A licensed plumber can confirm the material in a short visit.
Polybutylene degrades from the inside when exposed to chlorine-based disinfectants in treated water. McKinney is supplied by the North Texas Municipal Water District, which uses chloramine most of the year and converts the whole system to free chlorine for about a month each spring as routine maintenance. That annual conversion is safe and normal for drinking water, but it means McKinney polybutylene has been exposed to that chemistry every year since installation.
One leak in one location with sound pipe elsewhere is a repair. Leaks in two or more separate areas within a year, falling pressure across the whole house, or confirmed polybutylene anywhere in the system point to a repipe. Partial polybutylene replacement usually turns into a full repipe within a few years, because every original run is on the same timeline.
Yes. Repiping removes, replaces, and relocates piping, so it requires a residential stand-alone plumbing permit through the City of McKinney Citizen Self-Service portal, with inspection before walls are closed. We pull the permit as part of the job. Confirm current requirements with City of McKinney Building Inspections at 469-617-4800 for your specific project.
PEX for most residential repipes. It handles North Texas temperature swings, runs cleanly through an attic, and uses far fewer joints than copper, which means fewer future failure points. PEX is standard in new DFW construction.
Most single-family repipes run a few days depending on size and layout, plus drywall patching after inspection. Water is shut off in sections during working hours and turned back on at the end of each day, so you stay in the house.
Comparison
Repair or Repipe
The honest split is about whether you have a part problem or a system problem.
| Situation | What it usually means |
|---|---|
| One leak, one location, sound pipe elsewhere | Repair it. A repipe is not warranted |
| Leaks in two or more separate areas in the same year | System problem. Fixing one while the next forms costs more over time |
| Confirmed polybutylene anywhere in the house | Every run is on the same chemistry timeline. Partial replacement usually turns into a full repipe within a few years |
| Galvanized steel, any condition | Corrosion is internal and progressive. Plan the replacement rather than react to it |
| Pressure dropping across the whole house, not one fixture | System problem |
| Discolored or metallic-tasting water at multiple fixtures | System problem |
| One failing line under the slab | Different job. See our slab leak repair in McKinney page |
We tell you which one you have after walking the system, and we quote it flat before we start.
