Electronic Leak Detection Plano TX uses acoustic listening devices, thermal imaging cameras, and pressure testing kits to pinpoint hidden water line and slab leaks without tearing up your floors. We serve homeowners and property managers across Collin County, from Deerfield to Legacy West. If your water bill jumped or a warm spot appeared on the floor, we find the source the same day and tell you exactly what it takes to fix it.
Electronic Leak Detection Plano TX is a non-invasive diagnostic service that locates hidden water leaks in slab foundations, underground service lines, and interior walls using acoustic listening devices, thermal imaging cameras, and pressure testing kits. Instead of breaking concrete to hunt for a leak, we pressurize the line, listen for the escaping water, and map the temperature difference the leak creates. The result is a marked spot on your floor or yard, usually accurate to within a few inches, so repair crews cut once and cut small.
Plano homes sit on expansive clay soil that swells after heavy rain and shrinks hard in summer drought. That cycle stresses copper pipe and PEX tubing under slabs and shifts the soil around underground service lines. By the time you notice a high water bill or a warm spot on the floor, water has often been moving under the foundation for weeks. Our digital leak detection Plano TX service catches it early, before foundation moisture turns into a cracked slab or mold growth from leaks inside a wall cavity.
Every detection visit covers the full diagnostic sequence: zone isolation, pressure testing, acoustic scan, thermal scan, and a written finding with photos. Repair work is quoted separately once we know what we are dealing with. Here is what you get on the standard visit.
We isolate the hot side, cold side, and irrigation line and pressure test each one for 10 to 15 minutes. This tells us which line is losing water before we scan, and it narrows the search area by half or more.
We pressurize the suspect line and walk the slab with LeakTronics acoustic listening devices. The microphone picks up the frequency of escaping water. On a typical slab leak, the signal is clear enough to mark the spot within a few inches.
A Fluke thermal imaging camera shows the temperature difference the leak creates in the slab. Hot-side leaks show as warm bands; cold-side leaks show as cool spots. We overlay the thermal image with the acoustic reading to confirm the location.
We take moisture meter readings at the marked spot and compare them to a dry reference point nearby. This third data point confirms the leak location before we put tape on your floor, so your repair crew is not chasing a false positive.
You get a written report with the leak location, the affected line, thermal scan photos, and pressure test results. Hand it to your repair plumber or insurance adjuster. It documents the problem without anyone having to open a wall or break concrete to prove it.
You call and describe the symptoms: high water bill, warm floor spot, sound of running water with everything off. We ask for your ZIP code and the address, then schedule a prompt or next-morning visit. Most Plano calls in 75093, 75023, and 75025 get a two-hour arrival window.
On arrival, we shut off the main and isolate the hot side, cold side, and irrigation separately using pressure testing kits. Each zone holds pressure for 10 to 15 minutes. This step tells us which line is leaking before we bring in the listening gear, and it takes about 30 minutes.
We pressurize the suspect line and walk the slab with acoustic listening devices and a thermal imaging camera. The microphone picks up the hiss of escaping water; the camera shows the temperature difference. Together they triangulate the leak to a spot we mark with tape on your floor.
We confirm the location with a second method, usually a moisture meter reading at the marked spot. You get a written finding with the leak location, the line affected, and photos of the thermal scan. This is the document your repair plumber or insurance adjuster needs.
If you want us to handle the repair, we quote it on the spot. If you have your own plumber, we hand off the marked location and the written finding. Either way, you know what is wrong and where before anyone breaks concrete. Most jobs wrap in two to four hours total.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Amplifies the sound of escaping water through concrete and soil. We use it to pinpoint slab leaks and underground line breaks to within a few inches.
Maps temperature differences in the slab. Hot-side leaks show as warm bands, cold-side leaks as cool spots. We overlay the thermal image with the acoustic reading to confirm the location.
Pushes a camera through drain and sewer lines to find cracks, root intrusion, and joint failures. We use it when the leak is on the drain side rather than the supply side.
Traces buried service lines and irrigation runs before we scan. Knowing the exact path of the pipe keeps us from digging in the wrong spot.
Isolates the hot side, cold side, and irrigation line and holds pressure for 10 to 15 minutes per zone. This step tells us which line is leaking before we bring in the listening gear.
Confirms the leak location with a third data point. We compare the reading at the marked spot to a dry reference point nearby before we put tape on your floor.
A Deerfield homeowner had a water bill that jumped from $80 to $240 in one month. No visible water, no wet spots. Two other plumbers suggested breaking concrete in the hallway to look around. The homeowner called us instead of authorizing the dig.
We isolated the hot side, pressure tested it, and found a 12 psi drop in 15 minutes. Acoustic and thermal scans marked the leak within four inches under the hallway floor. The repair crew opened a 2-by-3 section, replaced 18 inches of copper pipe, and patched the slab. Total repair cost was $780 instead of the $2,400 exploratory dig the other plumbers quoted.
A Windhaven property had a wet patch in the yard that never dried, and the irrigation system lost pressure within 10 minutes of turning on. The homeowner had already dug two dry holes trying to find the break. The line ran 140 feet from the meter to the house.
We traced the line with a SubSurface Instruments pipe locator, then scanned with acoustic gear. The break was 62 feet from the meter, under a flower bed. We marked it with a flag, and the homeowner's landscaper made a small dig and repaired the PVC pipe in under two hours. Water pressure returned to normal the same day.
A Whiffletree homeowner felt a warm spot on the bathroom floor that grew from the size of a dinner plate to the size of a doormat over three weeks. The water heater was working fine. The home had original 1978 copper pipe under the slab.
We pressure tested the hot side and found a 15 psi drop. The thermal camera showed a clear warm band running under the bathroom tile, and the acoustic device confirmed the leak within three inches. We repaired the copper pipe through a small access cut, patched with concrete patching compound, and retiled the section. The warm spot was gone within a day.
Most Plano leak calls start with a symptom, not a visible puddle. Here are the problems we hear most often, what happens if you wait, and how we handle each one.
Ask a pro →We isolate each zone with pressure testing kits, then scan with acoustic and thermal gear to find the loss. Most hidden leaks are marked within two hours, and you get a written finding to hand to your repair plumber or insurance adjuster.
We pressure test the hot side first, then scan with a thermal imaging camera to map the warm band. The leak is marked within a few inches, and we quote the slab repair on the spot so you can decide the same day.
We shut the main, isolate the zones, and listen with acoustic devices to trace the sound to its source. If the leak is underground, we use a pipe locator to trace the run before we scan, so we dig in the right spot.
We use moisture meters to map the wet area, then scan with thermal and acoustic gear to find the source. Once we mark the leak, we can repair the line and dry the area before mold takes hold.
Most electronic leak detection jobs in Plano run $250 to $550 in 2026, depending on how many zones we isolate and whether the leak is under a slab or in a yard line. That fee covers the full scan, the pressure testing, and a written finding with photos. If you hire us for the repair, we credit the detection fee toward the work.
We isolate your hot, cold, and irrigation lines with pressure testing kits, then pressurize the suspect line and listen with acoustic devices while scanning the floor with a thermal imaging camera. Escaping water makes a sound and a temperature difference. We triangulate both signals to mark the leak within a few inches, usually in under two hours.
Yes. Combining acoustic listening with thermal imaging and a moisture meter confirmation puts us within a few inches of the leak on most slab and underground lines. We confirm with a second method before we mark the spot, so your repair crew cuts once. Accuracy drops only when a line is buried deeper than six feet or under thick rebar mesh.
We use LeakTronics acoustic listening devices, Fluke thermal imaging cameras, RIDGID SeeSnake video inspection cameras, SubSurface Instruments pipe locators, and digital moisture meters. Pressure testing kits isolate each zone first. For underground lines we add a SewerVUE camera and pipe locator to trace the run before we scan.
Slab Leak RepairOnce electronic detection marks the spot, we open the slab, repair the copper pipe or PEX tubing, and patch with concrete patching compound. Most Plano slab repairs are done in one day, and we test the line before we close it up.Explore →
