A slab leak rarely shows itself until damage is underway. By the time you notice a warm patch on the floor, water may have been running under your foundation for weeks. Herndon McFarland Plumbing has handled slab leak detection and repair in Farmers Branch since 1995. Our crews bring over 100 years of combined experience to detect leaks others miss.

We cover the full scope of Farmers Branch slab leak detection and repair.
We pinpoint the leak with acoustic listening gear and line tracing. This lets us open the smallest section of slab, keeping repairs contained and costs down.
By using static and hydrostatic isolation testing, we confirm whether the leak is on the pressurized supply side or the drain side. This tells us exactly which system failed.
Warm spots, unexplained moisture, and spikes in your water bill indicate leaks you cannot see. We cover slab leak detection from symptoms to source.
When we find a single isolated pinhole in a sound pipe, we open a small access point, repair that section, and restore the slab. This is the least invasive option if the rest of the line is healthy.
When a line has worn or corroded in multiple places, we abandon the failed run and reroute fresh pipe through the walls and attic. This prevents reopening the slab later.
When wear is widespread, a full repipe in modern materials ends the cycle of repeated leaks. We size and route the new system to keep it leak-free for decades.
If the existing pipe qualifies, we can line the interior to seal pinholes without full excavation, preserving the run.
Slab leaks often involve a claim, so we document our findings and work with your adjuster to keep the claim moving.
We get more slab leak calls about hot water lines than cold ones for a mechanical reason. Nearly every home in Farmers Branch sits on a slab-on-grade foundation with copper supply lines running through or beneath the concrete. Those hot lines heat and cool whenever someone showers, runs the dishwasher, or does laundry.
Copper expands as it heats and contracts as it cools. Over thousands of cycles, an unsleeved line saws against the concrete, aggregate, or rebar around it. The plumbing code anticipates this. The International Plumbing Code requires piping passing through concrete to be protected by sheathing that allows for the pipe’s expansion and contraction.
On older Farmers Branch buildings where that protection was thin or skipped, friction wears a groove into the copper until the wall is perforated. Because the line is buried in the slab, the leak is hidden. Homeowners feel a warm spot underfoot, see a water bill climb, or hear water running with every fixture shut off.
This pattern affects how we approach the job. We use isolation testing to confirm the leak is on the hot supply side and to pinpoint it with electronic, acoustic, and pressure equipment. Then we decide whether a spot repair, reroute, or repipe with a sleeved or flexible line is the lasting fix.

A slab leak gets more expensive the longer it runs under your foundation. We treat detection as urgent.

If testing shows a failing line, we will walk you through piping and repiping options or our full plumbing services. You get written pricing before any concrete is opened.
Common signs are a warm or damp spot on the floor, a sudden jump in the water bill, low water pressure, the sound of running water when all fixtures are off, and new cracks in the flooring. One sign alone can have other causes, but two or more are a strong reason to test before damage spreads.
Yes. We start with isolation testing to confirm the leak is on the pressurized side. Then we use electronic, acoustic, and pressure equipment to locate it within a small area. That focused approach helps us open inches of slab, not a whole room.
Depending on the pipe’s condition, we offer spot repair for a single pinhole, rerouting when a line has failed in several places, a whole-home repipe when wear is widespread, and epoxy lining where the pipe qualifies. We recommend the least invasive option that will last.
A single spot repair is the lowest-cost option, often costing a few hundred dollars to around $1,500. Rerouting one line usually lands in the low thousands, and a whole-home repipe commonly runs from about four thousand to over twelve thousand dollars, depending on the home’s size and pipe material. We confirm the figure in a written estimate after testing.
Two local factors stack up. Most homes here are slab-on-grade with copper running inside the concrete, and the hot lines wear out from years of expansion and contraction rubbing against the slab. That is why hot-side leaks are so frequent. Add constant foundation movement in North TX soil, and buried copper takes stress from both directions.
