A hidden leak is often the costliest. By the time a leak under your slab or behind a wall shows signs, it has usually run for weeks. Herndon McFarland Plumbing has pinpointed and repaired these leaks for Farmers Branch homeowners since 1995. The sooner we find the source, the less you pay to fix it.

We use pressure sensors, thermal imaging, and acoustic sensors that detect water escaping from buried or in-slab lines. Identifying the failure lets us open one small area, not the whole floor.
Lines beneath your foundation are the hardest to spot and the most damaging to ignore. We locate them precisely and explain every option from spot repair to overhead reroute.
We fix the cause, not just the puddle. Dripping faucets, failing supply lines, and leaking fixtures are diagnosed and repaired in one visit whenever parts allow.
For leaks inside a wall or under flooring, we expose only what we must and document the moisture path.
A hydrostatic test confirms whether an underground waste line holds water. When it flags a problem, static isolation testing narrows the leak to a specific section so the repair is targeted rather than guessed.
If an aging pipe is failing in several places, another patch can cost you more. We explain when a full repipe is a long-term option.
Farmers Branch grew rapidly. Developers built thousands of homes using Type M copper for interior supply lines. Type M is the thinnest-walled copper permitted under residential plumbing standards. Its wall dimensions are governed by ASTM B88, the Standard Specification for Seamless Copper Water Tube. At installation, Type M was code-compliant and adequate. Sixty to seventy years later, much of it is past its service life, and Farmers Branch is now in that window.
Thin-wall copper in continuous soil contact develops electrochemical pitting over decades. A pinhole opens, weeps slowly into the surrounding material, and shows no visible sign. Because the pipe runs under your slab, neither the drip nor the wet spot is accessible. The water bill arrives last, long after the leak has saturated the soil and changed the moisture beneath the foundation.
What makes this a Farmers Branch problem is timing. Newer subdivisions to the north and east are fifteen to thirty years behind this curve. Older inner-city neighborhoods replaced their copper decades ago. Farmers Branch is now in the actuarial window, which is why leak detection calls here mostly find pipe-wall failures rather than joint or fitting failures.
Herndon McFarland Plumbing uses electronic and acoustic equipment to locate the exact failure point before opening any concrete. For end-of-life copper, precise location is essential; it determines whether a repair stays contained or requires a full repipe evaluation.
The reviews below show what that looks like for two homeowners who needed leaks handled with care.
Indugu reached us through a referral from another company. What stood out was the diagnosis and how the home was treated during the work.
He wrote:
“The employees were very professional and on time. Explained to the customer what needed to be completed so the customer would understand. Protected my contents from dust and careful not to damage any contents.”
Protecting a home and explaining the plan in plain terms is our standard on every leak detection visit in Farmers Branch. Read Indugu’s full Google review.
A slab leak is rarely a one-person fix, and Pamela Spooner saw the depth of our bench from the first questions to the final follow-up.
She shared:
“I would highly recommend using Herndon McFarland for plumbing repairs. Each team member that I encountered exhibited professionalism and expertise. Shawn patiently answered all of my questions. Chris and Alex performed the slab leak repair, with a follow up by Carter and David.”
Coordinating crews and a follow-up visit ensures a slab leak repair holds when the leak is under your foundation. Read Pamela’s full Google review.

Watch for a water bill that climbs with no change in use, running water sounds when fixtures are off, warm spots on a slab floor, low pressure, or musty stains. Any of these is a reason to schedule a leak detection visit.
We isolate and pressurize the suspect line, then use thermal imaging and acoustic sensors to trace where water escapes. Leak detection identifies the exact failure point, so the repair opens only one small area rather than the whole floor.
Yes. The location step is non-invasive. We open concrete or drywall only after the leak is located. It keeps leak detection and repair low in cost and cleanup.
A single isolated failure usually warrants a spot repair. When the pipe is failing in several places, often from clay movement, a reroute or full repipe is more economical, and we give you the numbers for both.
Expansive North Dallas clay swells and shrinks with the seasons, stressing slab pipe until joints separate and copper cracks. That soil movement is the leading cause of recurring leaks.
Book online, and we will confirm a visit, often the same day, then diagnose and quote the repair upfront before any work starts.

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.
