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.”

FAQ

Frequently Asked Questions

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

It depends entirely on what is wrong, which is why we will not quote it over the phone. A cleaning runs $250 to $900. A spot repair runs $1,500 to $5,000. CIPP lining runs $80 to $250 per foot. Pipe bursting runs $100 to $300 per foot. A full open-trench replacement runs $4,000 to $15,000 or more. The camera inspection that tells us which one you need runs $150 to $400, and it is the best money you will spend on this problem.

Because we would be guessing, and guessing benefits us and not you. There is no way to know whether your line needs a $350 cleaning or a $12,000 replacement until somebody puts a camera in it. Anybody who quotes sewer work sight-unseen is either padding for the worst case or lowballing to get in your driveway and revise upward later.

If only one fixture is affected and everything else drains fine, it is that fixture. If the toilet backs up when the washing machine drains, if the tub gurgles when you flush, or if more than one fixture is backing up, the problem is in the main line. A new toilet will not fix that.

Almost certainly cast iron, which lasts 50 to 75 years. Yours is at or past the end of that window. Cast iron fails from the inside out. The bottom of the pipe corrodes away first, which you can see clearly on a camera. If that line has never been scoped, that is the single most useful thing you can do for that house.

A belly is a low spot where the pipe has settled and waste pools instead of flowing. Cleaning it will make it work for a while, and then it will do it again, because the low spot is still there. A belly has to be dug up and re-graded, or the section replaced. Anybody who tells you a liner will fix a sag is wrong. A liner takes the shape of the pipe it goes into.

It is usually less disruptive and often the right call, and we recommend it when it fits. But it is not automatically cheaper and it is not always possible. Lining will not fix a collapse, a severe belly, or badly deformed Orangeburg. Pipe bursting needs access pits and clearance from other utilities. We will show you the camera footage and tell you honestly which methods your line is a candidate for.

Sometimes, and sometimes not. Pipe bursting and CIPP lining need access points rather than a full trench. A spot repair means one excavation. A full open-trench replacement means a trench. Where the defect is, how deep it sits, and whether the line runs under your slab all determine that, and we will mark the location in the yard before anybody picks up a shovel.

Plano is slab-on-grade, so this happens. The options are tunneling in from outside, which costs more but leaves your floor intact, or breaking through the slab from inside, which costs less but puts a hole in your floor that has to be repaired afterward. This is where a sewer job goes from four figures to five, and it is also where a bad diagnosis is most expensive, which is why we locate and mark before anybody breaks anything.

Yes, and almost nobody tells you this. A standard home inspection does not include a sewer camera. If the house is over thirty years old, a $150 to $400 scope is the highest-value inspection you can buy. Either you sleep at night or you just found a five-figure negotiating position before closing.

If you do not have one, yes. Without a cleanout we may have to pull a toilet to get access to your line, which is slower and messier for you. Many older Plano homes were built without one. Installing one runs $400 to $1,200 and it pays for itself the first time your line backs up.

No. It will not clear a main line, because the water already standing in the line dilutes it before it reaches the blockage. What it will do is leave a caustic liquid sitting in your pipe for whoever opens that line next. Do not do it, and do not let anybody tell you otherwise.

Stop using water. All of it. No toilets, no laundry, no dishwasher, no showers. Everything you send down is coming back up. Then call 214-918-6109. That one is a real emergency and it does not wait for morning.

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

Comparison

What the Camera Actually Finds

FindingWhat it meansWhat fixes it
Roots at a jointRoots found a hairline gap and grew in. Very common in older Plano neighborhoods with mature trees.Root cutting and jetting buys time. A liner or a spot repair fixes it permanently.
Grease buildupKitchen line, usually. Accumulates over years.Hydro jetting. Then stop pouring grease down the sink.
Belly (sag)The pipe has settled into a low spot. Waste sits there instead of flowing.Cleaning does not fix this. It has to be dug and re-graded, or the section replaced.
Offset jointTwo pipe sections have shifted out of line. Waste catches on the lip.Spot repair or lining, depending on severity.
Channeling in cast ironThe bottom of the pipe has corroded away. You are looking at dirt through the pipe.Lining or replacement. The pipe is structurally done.
Cracks or fracturesMovement, root pressure, or age.Lining if the pipe is otherwise round. Replacement if not.
Full collapseSection has caved in.Excavation or pipe bursting. No way around it.
Deformed OrangeburgThe pipe has gone oval.Full replacement. There is no repairing Orangeburg.
Clean line, minor blockageGood news. You have a clog, not a sewer problem.Auger or jetting. A few hundred dollars and you are done.

That last row happens more often than the industry likes to admit. Sometimes a backed-up house is just a backed-up house. We will tell you that and we will charge you for a cleaning, not a replacement.

Repair Methods, Compared Honestly

MethodWhat it isCostBest whenNot when
Cleaning / jettingClear the line, no structural fix$250 to $900The pipe is sound and the problem is buildup or rootsThe pipe has a belly, a collapse, or is channeling. It is a delay, not a fix.
Spot repairExcavate and replace one bad section$1,500 to $5,000One localized defect, rest of the line healthyMultiple defects along the run
CIPP liningA resin liner cured in place inside the old pipe$80 to $250 per footCracks, roots, minor offsets, and cast iron that is still roundThe pipe has collapsed, has a severe belly, or is badly deformed. A liner follows the shape of what it lines. It cannot fix a belly.
Pipe burstingNew pipe pulled through, shattering the old one outward$100 to $300 per footFull replacement with minimal digging. Works on cast iron, clay, Orangeburg.Pipe under a slab with no access pits, or where other utilities are too close
Open trenchDig it up and replace it$4,000 to $15,000+Collapse, severe bellies, re-grading required, or when trenchless access is not possibleAnytime a trenchless method would work. It is the most disruptive and usually the most expensive.

The honest read on trenchless: it is genuinely better in most cases, and we recommend it when it fits. But it is not magic, and “trenchless” is not automatically cheaper. A liner cannot fix a belly, because a liner takes the shape of the pipe it goes into. Any contractor who tells you a liner will solve a sag is selling you a problem you will pay for twice.
