Careful work. Honest options.
About this service
What Underground Leak Detection Plano TX Really Involves
Underground Leak Detection Plano TX is a diagnostic service that locates water escaping from buried or under-slab pipes without tearing up your property to find it. We pressurize the line with a pressure testing kit, then walk the run with acoustic listening devices and a pipe locator to hear and map the break. Thermal imaging cameras confirm the wet zone, and a moisture meter verifies what the readings say. The result is a marked, measured location you can hand to any repair crew.
Plano sits on expansive clay soil that swells and shrinks with every wet and dry cycle, and that movement stresses copper pipe and PVC pipe buried under slabs and lawns. Add the freeze events North Texas gets most winters, and you have ideal conditions for a water line break you cannot see. When a homeowner searches for subsurface leak detection Plano TX near me after a spike in the water bill, this is the call that answers it.

What's included
What Our Detection Service Includes
Every detection visit covers the diagnostic work needed to find and mark the leak. Repair is quoted separately once we know what we are dealing with, and you get that number before any repair work begins.
✓
Full System Isolation
We separate domestic supply, irrigation, and pool lines and pressure-test each zone. This rules out false alarms and tells us which system is actually losing water before we spend time chasing the wrong pipe.
✓
Acoustic and Thermal Sweep
Acoustic listening devices and thermal imaging cameras sweep the suspect run. We cross-check the readings so the mark holds up when the repair crew opens the ground or the slab.
✓
Marked Location and Photos
We paint the spot on the slab or ground, photograph the readings, and note the depth estimate. You keep the photos for your records and for any insurance conversation.
✓
Written Findings Walkthrough
We walk you through what we found in plain language: which line, how deep, and what the repair involves. No jargon dump, no pressure to book the repair on the spot.
✓
Post-Repair Pressure Test
If we handle the repair, we pressure-test the line before we leave. A dry line that holds pressure is the only proof that matters, and we do not call a job done without it.
How it works
How Our Detection Process Works
01
Phone Triage
We ask about your water bill, the meter test, warm spots on the floor, and where you hear running water. That five-minute call tells us whether this is a slab leak, an irrigation line, or a supply line in the yard, and we book a prompt window.
02
System Isolation
On arrival we shut off fixtures and isolate the domestic supply from irrigation and the pool line. A pressure testing kit confirms which system is losing pressure. This step alone rules out half the false alarms and takes about 20 minutes.
03
Acoustic Sweep
We pressurize the isolated line and walk it with acoustic listening devices, headphones on, listening for the hiss of escaping water. A pipe locator traces the run so we know exactly where the pipe sits under the slab or lawn.
04
Thermal and Moisture Confirmation
Thermal imaging cameras show the temperature difference a leak creates, and a moisture meter confirms the reading. Two independent tools agreeing on one spot is how we get accuracy you can build a repair around.
05
Mark and Report
We mark the location on the slab or ground, photograph the readings, and walk you through what we found. You get the marked spot, the depth estimate, and a clear picture of what the repair involves before anyone cuts.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Acoustic listening devices
Headphones and a ground microphone pick up the hiss of pressurized water escaping a buried pipe. This is the primary tool for pinpointing the break on a supply or slab line.
Thermal imaging cameras
Infrared cameras show the temperature difference a leak creates under a slab or in a wall. We use them to confirm what the acoustic sweep heard and to find hot-line leaks fast.
Pressure testing kits
We pressurize each isolated zone and watch the gauge. A zone that will not hold pressure is the one with the leak, which saves hours of chasing the wrong pipe.
Pipe locators
A pipe locator traces the buried run so we know exactly where the pipe sits under the slab, lawn, or driveway. It keeps the mark on the pipe, not just near it.
Moisture meters
A moisture meter confirms the wet zone and gives us a reading to compare before and after. It is how we prove the leak is fixed and the area is drying.
RIDGID SeeSnake video inspection cameras
When a drain or line is suspect, the SeeSnake lets us look inside the pipe and see cracks, offsets, or root intrusion instead of guessing from the surface.
Real results
Before and after.
High Water Bill Traced to Yard Line
Before
A West Plano homeowner saw the water bill triple in one cycle. The meter spun with every fixture off, and two other companies had guessed at the slab without confirming. The yard was already torn up in two spots.
After
We isolated the irrigation zone, pressure-tested it, and found a split lateral under the lawn within 90 minutes. The mark was within a foot of the break. The repair crew dug one hole, fixed the line, and the next bill dropped back to normal.
Warm Spot Confirmed as Hot-Line Slab Leak
Before
A Willow Bend family felt a warm patch on the hallway tile and smelled damp near the baseboard. They feared a full floor tear-out and had already gotten a quote for replacing half the hallway flooring.
After
Thermal imaging found the hot-line break within 20 minutes, and a moisture meter confirmed the wet zone. We marked a spot under two square feet. The repair crew opened one section, fixed the copper pipe, and patched with concrete patching compound. The flooring replacement was cancelled.
Meter Spinning After Freeze Event
Before
After a hard freeze, a homeowner in Old Shepard Place heard water running but could not find it. The meter spun constantly, and the yard near the foundation was soggy. The house had original copper service lines.
After
We pressure-tested the domestic line, isolated a split section, and marked it with acoustic listening devices. The break was under the driveway edge. One cut, one repair, and a pressure test before we left. The meter stopped spinning and the yard dried out over the next week.
Problems we solve
Underground Leak Problems We Solve in Plano
Most underground leaks announce themselves through the water bill or the meter, not through a visible puddle. Here are the situations we get called for most, and what happens if they sit.

Meter spins with every fixture shut off
This is the classic slab leak signal. We pressure-test the domestic line, sweep it with acoustic listening devices, and confirm with thermal imaging. You get a marked spot and a repair plan the same day.
Warm spots on the floor or damp carpet
Thermal imaging cameras pick up the temperature difference fast. We confirm with a moisture meter, mark the break, and hand you a repair scope that limits how much flooring has to come out.
Water pooling in the yard or near the foundation
We trace the buried line with a pipe locator, listen for the break, and mark the trench line. Repair crews then dig once at the mark instead of probing across the yard.

Most residential detection jobs in Plano run $250 to $550 in 2026, depending on how many systems we have to isolate and how deep the line sits. A single slab supply line is on the low end; multiple zones, pool lines, or irrigation crossovers push it higher. You get the number before we start, and the detection fee is separate from the repair.
We isolate the suspect line, pressurize it, and listen for escaping water with acoustic listening devices while a pipe locator maps the run. Thermal imaging cameras and a moisture meter confirm the wet zone. Two tools agreeing on one spot is what separates a real detection from a guess, and it usually takes two to four hours.
Yes. Detection is non-invasive by design. We never break concrete or dig to find the leak; we mark the spot from the surface using acoustic and thermal equipment. The only digging happens later, during the repair, and it is limited to the marked area, which is usually under two square feet.
