Finding a Richardson plumber is easy. Finding one who has worked in the same suburb long enough to know what is buried under it is harder. We at Herndon McFarland Plumbing have served Richardson since 1995, and our team brings over 150 years of combined experience to homes now old enough to show their age underground.

Richardson homes present everything from dripping faucets to failed sewer mains, so we kept our service list broad rather than specializing. Whatever you have found is on this list.
Every one of these is handled by our licensed technicians rather than subcontracted. This is why we guarantee labor.
Richardson did not grow gradually. It exploded, and every house from that surge is reaching the same milestone at once. The City of Richardson’s history records that forty percent of its homes were built between 1970 and 1979, after Collins Radio arrived in 1958 and turned a town of roughly 1,300 people into a city of about 56,000 by 1972.
Those homes were plumbed with the materials of their day: cast-iron drain lines under the slab and supply piping that has spent half a century carrying mineral-rich North Texas water. Cast iron does not fail politely. It scales inward, then cracks along the bottom of the pipe where it has sat in waste for fifty years. The first symptom is usually a slow drain or a damp patch on a hallway floor.
That is the specific problem this suburb presents to plumbers, and it is why we invested in crews and equipment to tunnel under a slab rather than jackhammer through your flooring. Knowing which decade a street was built tells us what we are likely to find before we open anything.
Most of what we get called out for gives warning first. These are the ones worth acting on before they turn into a tunnel under your slab.
Drains that Slow Down Across the House
One slow sink is a clog. Two or three at once usually means the problem is farther down the main line, which, in a 1970s Richardson home, often means cast iron.
A Water Bill That Climbed Without Explanation
If nothing about your usage changed, water is going somewhere. Under a slab, it can run for months without ever showing on the surface.
Warm Patches on the Floor
A hot water line leaking beneath the slab heats the concrete above it. Barefoot in the morning is how most people notice.
Running Water You Cannot Account For
With every fixture off, the sound of water moving in a wall or beneath the floor indicates a leak on a pressurized line.
Rust, Smell, or Gurgling from the Drains
Gurgling means air is being pulled through a partial blockage or a failing vent. An indoor sewer smell means gas is escaping where it should not.
Water Pressure that Drops Off Over Time
Gradual loss throughout the house usually points to scale and corrosion narrowing the supply piping rather than to a single fixture problem.
If you are seeing any of these, a diagnosis costs far less than what ignoring them would.
L Good was referred to us by a structural engineer during major home repairs and has since had us out twice. Shawn was the point of contact throughout.
“Shawn was our point of contact, and he is a person of integrity and has managed our projects with the highest level of customer service. I highly recommend this plumbing company. The service is stellar!!”
Referrals from structural engineers matter more than most, because they see the aftermath of bad slab work for a living. Read L Good’s full Google review.
Brian Hiatt needed a 21-foot tunnel dug and a drain line replaced. An ice storm stopped the crew from reaching him, so the office staff took his details home and called from a personal phone to reschedule.
“When they could not make it out due to the ice storm, the office actually took our info home and called from their personal cell phone to reschedule. They could have taken the day off, but chose to serve us.”
That tunnel is exactly the work Richardson’s 1970s slab housing generates, and it is why we keep excavation crews on staff. Read Brian’s full Google review.

Slab leaks are a significant issue in older Richardson homes because many were built decades ago and have aging water lines beneath the concrete foundation. Richardson’s expansive North Texas clay soil moves as moisture levels change, stressing underground plumbing connections and lines. Corrosion, pipe deterioration, shifting soil, and long-term wear contribute to leaks beneath the slab. Since the plumbing is beneath concrete, early detection is important to prevent moisture in the foundation, flooring damage, and water waste.
A sudden increase in your water bill, the sound of water running when all fixtures are off, warm or damp floor areas, unexplained moisture, low water pressure, or persistent cracks around flooring can indicate a slab leak. Some leaks are hidden and show few symptoms until causing significant water loss. Our Richardson plumbing team uses professional leak detection to locate the problem beneath the foundation and determine if the leak is on a hot- or cold-water line before recommending the least disruptive repair.
Not necessarily. Depending on the location, depth, pipe condition, and accessibility of the leaking line, a slab leak may be repaired through access inside the home, tunneling beneath the foundation, or another targeted method. Tunneling allows plumbers to reach some under-slab lines from outside without removing large sections of flooring, cabinets, or finished surfaces. We inspect the plumbing and determine the appropriate repair method for your Richardson property, rather than assuming every slab leak requires the same approach.
A sewer line does not automatically need replacement due to a blockage or a damaged section. We recommend a sewer camera inspection to assess the pipe’s condition, including root intrusion, cracks, joint separations, corrosion, collapsed sections, or recurring blockages. A localized problem may be repairable, while extensive deterioration or repeated failures may make replacement more practical. For Richardson properties with aging underground sewer lines, we use inspection findings to explain your repair and replacement options before work begins.
The timeline depends on the sewer line’s length and depth, the condition of the existing pipe, access to the line, and whether excavation or trenchless methods are appropriate. A straightforward replacement may take a few days, while more complicated lines require additional time. We inspect the sewer line and evaluate the property to provide a realistic project timeline instead of promising a fixed completion time before seeing the problem.
Permit requirements depend on the type and scope of plumbing work. Routine repairs may not require the same permits as sewer replacements, repiping, new installations, or major plumbing alterations. When a permit is required, the work must comply with City of Richardson requirements and pass all inspections. We can help determine what is needed for your project and coordinate the permitting process when part of the job.
From slab leaks under the foundation to sewer line repipes, every job is diagnosed, documented, and done right. A look at recent work across North Dallas.
Excellent customer service, very friendly staff from the person taking the call to the staff fixing the repairs. Very trustworthy company. Shaun explained the step-by-step process and provided very fair prices.
Their positive, upbeat, anxious-to-please attitude made the whole process the very best it could be! All of the employees were a pleasure to work with. I highly recommend Herndon McFarland.
Trent and Reggie were the most professional associates entering our home. They treated our home with respect as if it were theirs. We will use this company again because of them and our experience.
