About this service
What Underground Leak Detection in Houston Actually Involves
Underground Leak Detection in Houston is the process of locating water leaks in pipes buried beneath your slab, yard, or driveway without tearing up concrete to find them. We start with a pressure testing gauge on your main line to confirm there is a leak, then use an acoustic listening device to hear the water escaping underground. A thermal imaging camera shows temperature differences where water is pooling, and a pipe inspection camera lets us see inside the line when needed. Once we know exactly where the break is, we mark the spot and give you a repair plan.
Houston homeowners call us for underground leak repair Houston TX because our soil shifts, our pipes age, and our water pressure runs high. Clay soil expands and contracts with every wet and dry spell, which cracks copper pipe and pulls apart PVC pipe fittings. If you have noticed a spike in your water bill, a warm spot on the floor, or the sound of running water when nothing is on, you need a pro who knows how to find underground water leaks Houston TX without destroying your yard. We handle slab leaks, water main breaks, and irrigation line failures across Harris County every week.

What's included
What Our Underground Leak Detection Includes
Every job includes the full detection process and a written price to repair. We do not charge extra for the pressure test or the thermal scan.
✓
Pressure Test
We isolate your main line and pressurize it with a hydrostatic test pump. If pressure drops, we confirm there is a leak underground. This takes about 20 minutes.
✓
Acoustic Listening
We use an acoustic listening device to hear the sound of water escaping. This narrows the leak location to a small area, usually within 6-12 inches.
✓
Thermal Imaging Scan
A FLIR thermal imaging camera shows temperature differences where water is pooling underground. We use it to confirm the acoustic findings.
✓
Pipe Inspection Camera
If needed, we run a RIDGID pipe inspection camera through the line to see cracks, root intrusion, or separated joints. You see the video too.
✓
Written Repair Quote
We mark the leak location and give you a written price to fix it. No obligation. If you want a second opinion, you are free to get one.
How it works
How Our Underground Leak Detection Process Works
01
Phone Triage
You call 832-839-4984 and tell us what you are seeing: high water bill, warm floor, sound of running water. We ask a few questions to narrow down whether it is a slab leak, a yard line, or a fixture. We schedule a same-day or next-morning visit, usually within a 2-hour window.
02
On-Site Pressure Test
Our licensed tech hooks a pressure testing gauge to your main line and isolates the system. If the gauge drops, we know there is a leak underground. This takes 15-20 minutes and confirms the problem before we start hunting.
03
Acoustic and Thermal Scan
We walk the property with an acoustic listening device and a thermal imaging camera. The acoustic device picks up the sound of water escaping under pressure; the thermal camera shows temperature changes where water is pooling. Together they narrow the leak to a small area, usually within 6-12 inches.
04
Mark and Confirm
We mark the spot with paint or flags and show you exactly where the break is. If you want, we can also run a pipe inspection camera through the line to see the damage. You get a clear explanation and a written price to repair.
05
Repair and Retest
Once you approve the price, we repair the line. That might mean a spot repair, a pipe reroute, or a full section replacement depending on the damage. After the repair, we pressure test again to confirm zero leaks, then clean up and haul off debris.
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 Device
Picks up the sound of water escaping under pressure. We use it to narrow the leak location to within inches.
Thermal Imaging Camera (FLIR)
Shows temperature differences caused by water underground. Confirms the leak location and helps us avoid digging in the wrong spot.
Pressure Testing Gauge
Confirms there is a leak by measuring pressure drop in an isolated line. The first step in every detection job.
Pipe Inspection Camera (RIDGID)
Lets us see inside the pipe to find cracks, root intrusion, or separated joints. You see the video too.
Tracer Gas Detector (Sewerin)
For hard-to-find leaks, we introduce a tracer gas and use a detector to find where it escapes. Works great for small pinhole leaks.
Moisture Meter (General Tools)
Measures moisture levels in walls and floors to confirm hidden leaks.
Hydrostatic Test Pump
Pressurizes a section of pipe to test for leaks. We use it to isolate the problem area.
Real results
Before and after.
Slab Leak in Meyerland
Before
Homeowner had a $220 water bill and a warm spot on the kitchen floor. They suspected a slab leak but did not want to tear up the floor.

Yard Line Leak in The Heights
Before
Soggy spot in the yard that never dried. Homeowner was worried about foundation damage.
After
We pressure tested the main line and found a cracked PVC pipe under the lawn. Repaired it in 3 hours. Yard dried out within a week.
Water Main Leak in Clear Lake
Before
Water bill jumped from $90 to $300. Homeowner heard water running at night but could not find the source.

We used acoustic correlation to find the leak under the driveway. Repaired the line with a spot repair. Bill dropped back to $95.
Problems we solve
Underground Leak Problems We Solve in Houston
If you have a hidden leak, we can find it. Here are the most common problems we see.
Ask a pro →↗
Warm spots on the floor
We use thermal imaging to confirm the leak and acoustic listening to pinpoint it. Then we repair the line and restore the slab.
Sound of running water when everything is off
We locate the leak with acoustic equipment and fix it. Usually same-day.
Cracks in drywall or sticking doors
We find the leak, stop the water, and give you a report you can use for insurance. We also recommend a foundation specialist if needed.
Transparent pricing
Underground Leak Detection Pricing
$250 - $1,800 depending on scope
We keep our pricing straight. Detection starts at $250 and goes up to $600 depending on the size of your property and how complex the leak is. If you need the repair too, expect $450-$1,800. We give you a written price before we start. No hidden fees. We are the affordable underground Leak Detection Houston TX option because we do not pad the bill.
Finding the leak fast saves you money on your water bill and prevents foundation damage. A $500 detection job can save you $10,000 in foundation repair. That is value you can measure.
01Property size
Larger homes and yards take longer to scan. A 1,500 sq ft home is faster than a 4,000 sq ft home with a large yard.
02Leak location
A leak under a slab is harder to access than a leak in the yard. We have to use more tools and take more time.
03Pipe material
Copper, PEX, and PVC all behave differently. Copper leaks are often pinhole leaks; PVC leaks are usually cracks at joints.
04Access
If the leak is under a driveway or patio, we may need to cut concrete. That adds time and cost.

The most common signs are a water bill that jumps 20% or more with no change in usage, a warm spot on your floor, the sound of running water when everything is off, or cracks appearing in your drywall. If you see any of these, call us. We can confirm with a pressure test in about 20 minutes.
