Pipe Leak Repair and Re-piping in Plano, TX

A pipe leak is two problems in one. There is the water you can see, and there is the question you cannot answer alone: is this one bad spot, or is the whole system telling you something? James Armstrong Plumbing answers both. We find the leak, fix it right, and give you a straight read on whether your Plano home’s pipes have years left or are quietly reaching the end.

We work Plano from our shop in Mesquite. A licensed Master Plumber leads the company, we have repaired and replaced North Texas pipe since 1995, and we hold a BBB A+ rating with 4.8 stars on Google. Leak calls move fast: call 214-918-6109 before noon and same-day service is often possible. Repipes are planned projects, quoted firm and scheduled around your life.

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.”

Single-spot repairs typically run $250 to $1,200 in the Dallas-Fort Worth area depending on access and location. Slab leaks and repipes run higher, and every job gets a firm written price before work begins. The ranges in the table above frame the decision.

When leaks become a pattern rather than an event. A second or third leak in a couple of years, rusty water, fading pressure, or any polybutylene in the house all point to repiping. One isolated leak in an otherwise healthy system is just a repair, and we will tell you which one you have.

Yes. Slow leaks feed mold, rot framing, stain ceilings, and quietly inflate your water bill. The EPA puts the average household's leak waste near 10,000 gallons a year. Early detection is always the cheap option.

Look for gray plastic pipe at the water heater, under sinks, or where lines enter the wall, often stamped PB2110. Homes built from the late 1970s through the mid 1990s are the risk window, which covers a large share of Plano. We confirm it during a standard evaluation and give you a straight answer on urgency.

Yes. During business hours, emergency calls run at standard rates and same-day response is often possible when you call before noon. After hours, a flat $199 emergency fee applies, quoted before we dispatch. We are honest that we are not a 24/7 call center. You reach real people who show up.

Two to four working days for most single-family homes, faster on smaller layouts. Water is typically restored each evening, and families routinely stay home through the job.

Far less than people fear. We plan access before cutting, route through the attic and existing chases where possible, and show you every planned opening in advance. PEX needs notably fewer openings than copper.

PEX wins on cost, speed, and freeze resilience for most Plano repipes. Copper remains a fine choice for exposed runs or personal preference. We quote both on request and explain the tradeoffs for your specific house.

Warm floor spots, wet carpet edges, and water bills climbing with no visible drip point under the slab. Damp cabinets, stained ceilings, and drips point to lines in walls and ceilings. Detection tells us for certain before anyone cuts anything.

Yes. Whole-home repiping is permitted and inspected work, and we handle both as part of the job.

Increasingly, yes. Some carriers surcharge or decline homes with polybutylene, and documented repiping can help at renewal time. We provide the documentation, though your agent is the final word on your policy.

Yes. James Armstrong holds Texas Master Plumber license M-39428 with a gas endorsement, and we carry full insurance on every job.

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

Comparison

PEX or Copper for a Plano Repipe

Leak Detection. Acoustic and pressure-based detection pinpoints hidden leaks in walls, ceilings, and under slabs before anyone opens anything. You see the evidence first.

Pipe Leak Repair. Pinholes, failed joints, frozen splits, and corroded sections repaired with quality materials and tested under pressure before we leave.

Slab Leak Response. Warm floors, wet carpet edges, and mystery bills. We locate under-slab leaks precisely and walk you through reroute versus direct repair with real numbers. Deeper detail on our slab leak detection and repair page.

Whole-Home Repiping. New PEX or copper supply lines throughout the house: planned access openings, water back on each evening in most cases, City of Plano permit and inspection handled, and every fixture flow-tested at the end.

Polybutylene Replacement. Full replacement of gray poly systems, documented so your insurer sees exactly what changed.

FactorPEXCopper
CostLowerOften 30 to 50 percent more
Wall openingsFewer, flexible routingMore access points
Freeze behaviorForgiving, flexes slightlyCan split when frozen
Track recordDecades, now the DFW standardHalf a century plus
Best useMost whole-home repipesExposed runs, personal preference

After the hard freezes North Texas keeps living through, PEX has earned its place as the default recommendation for most repipes here. We install both and will quote both when you want the comparison.
