About this service
Sewer Line Leak Detection in Houston: What It Is and Why It Matters
Sewer Line Leak Detection in Houston is the process of finding exactly where a buried sewer pipe is losing wastewater, using acoustic listening devices, pipe inspection cameras, and pressure testing gauges. We don't guess. We locate the break, measure the loss, and show you the evidence before anyone digs. That means less excavation, fewer repairs, and a fix that holds.
Houston's clay soil shifts with every wet-dry cycle, and that movement cracks older PVC pipe and pulls apart pipe fittings. Tree roots from live oaks and pecans find those cracks and make them worse. If you've noticed a sewer line backup, a high water bill, or a soggy patch in the yard, you need Houston sewer line Leak Detection before the problem spreads under your foundation. We handle emergency sewer leak repair Houston Texas calls 24/7.

What's included
What's Included in Our Sewer Line Leak Detection
Every Sewer Line Leak Detection in Houston job includes the full diagnostic package. We don't charge extra for camera inspection or pressure testing. You get the complete picture before you decide on a repair.
✓
Acoustic Listening Survey
We use an acoustic listening device to hear water escaping the line. This works best in quiet conditions and can narrow the leak to a 12-inch section of pipe.
✓
Pipe Inspection Camera
A RIDGID camera travels the line and sends back video of cracks, root intrusion, and corroded pipes. You watch the footage with us and see exactly what's wrong.
✓
Pressure Testing
We isolate the suspect section and pressurize it with a hydrostatic test pump. If the gauge drops, we know the line is leaking and how fast. This confirms the diagnosis before we dig.
✓
Thermal Imaging Scan
A FLIR thermal imaging camera shows temperature differences caused by escaping water. We use it to scan slabs and yards for moisture that isn't visible to the eye.
✓
Written Findings and Quote
You get a written summary of what we found, where the leak is, and what it costs to fix. No vague estimates. The price we quote is the price you pay.
How it works
What to Expect When You Call Us
01
Call and Schedule
Call 832-839-4984 and tell us what you're seeing: slow drains, gurgling toilets, a wet spot in the yard. We ask a few questions to narrow it down, then schedule a same-day or next-morning visit. Emergency calls get priority, including nights and weekends.
02
On-Site Inspection
A licensed technician arrives with an acoustic listening device, moisture meter, and thermal imaging camera. We walk the property, check the cleanouts, and listen for the telltale sound of escaping water. This takes 30 to 45 minutes for most homes.
03
Camera and Pressure Testing
We run a pipe inspection camera through the line to look for root intrusion, corroded pipes, and cracked joints. Then we isolate the section and use a hydrostatic test pump or pressure testing gauge to confirm the leak and measure how much water is escaping.
04
Locate and Mark
Once we've confirmed the leak, we mark the exact spot on the ground with paint or flags. You see the camera footage and the pressure readings. We explain what's broken, what it takes to fix it, and hand you a written price before we start.
05
Repair and Verify
We repair the line using code-approved pipe fittings, PVC pipe, or PEX tubing depending on what's already there. After the repair, we re-test the section with the hydrostatic pump to confirm zero loss. You get a clean line and a written warranty on the work.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
RIDGID Pipe Inspection Camera
Travels inside the sewer line and sends back video of cracks, root intrusion, and corroded pipes. We record the footage and share it with you.
Fluke Acoustic Listening Device
Amplifies the sound of water escaping the pipe. We use it to pinpoint the leak within inches before we dig.
FLIR Thermal Imaging Camera
Shows temperature differences caused by escaping water. We use it to scan slabs and yards for moisture that isn't visible.
Sewerin Tracer Gas Detector
Detects tracer gas introduced into the sewer line when acoustic methods can't isolate the leak. Works in noisy or deep-line conditions.
Hydrostatic Test Pump
Pressurizes the isolated sewer section to confirm the leak and measure water loss. We also use it after the repair to verify the fix.
General Tools Moisture Meter
Measures moisture content in soil, drywall, and concrete. We use it to confirm the leak's path and check for secondary damage.
Real results
Before and after.
Soggy Yard in The Heights
Before
A homeowner in The Heights had a wet spot in the yard that never dried. The water bill was up $90. A general plumber told them they needed to replace the whole line.
After
We ran a camera and found one cracked pipe fitting. We repaired it with a new PVC coupling and tested the line with a hydrostatic pump. The total repair took three hours and cost $420.
Sewage Backup in Third Ward
Before
A duplex in Third Ward had sewage backing up into both units. The property manager called us at 11 p.m. Tenants were ready to move out.
After
We located root intrusion 18 feet from the cleanout using an acoustic device. We cut out the roots, repaired the cracked section, and tested the line. The whole job was done by 2 a.m.
High Water Bill in Bellaire
Before
A Bellaire homeowner's water bill jumped from $180 to $340 in one month. No visible leaks inside or outside the house. They suspected a slab leak.
After
We pressure tested the sewer line and found a pinhole leak in a corroded section of pipe. We replaced the section with PEX tubing and re-tested. The next bill was $175.

01Line depth and access
Sewer lines buried deeper than 4 feet take longer to access and require more excavation. Lines under slabs add complexity because we have to locate the leak without breaking concrete.
02Length of the damaged section
A single cracked fitting is a quick repair. A 20-foot section of collapsed pipe needs more materials and labor. We measure the damaged section on camera and quote accordingly.
03Type of pipe
PVC pipe and PEX tubing are straightforward to repair. Older clay or cast iron pipe may need a transition coupling, which adds time and materials.
04Root intrusion severity
Light roots can be cut out. Heavy root intrusion that has cracked the pipe requires section replacement. We show you the camera footage so you see the difference.

“We had sewage backing up in a duplex and two tenants calling. These guys answered at 11 p.m., were on-site in 45 minutes, and located the root intrusion with an acoustic device. They repaired the line and tested it before they left. Saved us from a much bigger mess.”

“I was worried they'd have to dig up my whole yard. They used a thermal camera and a listening device, marked one spot, and dug a hole the size of a trash can lid. The repair was done in three hours. My yard looks fine and the line holds pressure.”
