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.”

we see.
We ask for a photo or short video when you schedule, arrive on time, protect
your floors, and explain each step before starting. You get clear updates,
upkeep tips, and a final flow test before we leave.

line, or root intrusion. We camera-inspect, walk you through what we find, and
fix the actual cause, not just the surface clog.

Hydro-jetting is quoted after inspection. Every job gets a written flat-rate
quote before we start.
Comparison
Hydro-Jetting vs. Snaking
| Factor | Snaking | Hydro-Jetting |
|---|---|---|
| Best for | Single-fixture clogs (kitchen sink, shower drain, single toilet) | Main-line buildup, grease, root intrusion, recurring backups |
| Method | Flexible cable with cutting head punches through the blockage | 3,500+ PSI pressurized water scours the full interior of the pipe |
| Typical time | 30–60 minutes | 90 minutes to 3 hours |
| Typical Rowlett cost | $150–$275 | $400–$800 |
| Our recommendation | Camera-inspect first. Snake when the inspection shows a localized blockage. | Camera-inspect first. Hydro-jet when the inspection shows full-pipe buildup or roots. |
