Leak Detection and Repair in Houston, TX
There's a wet spot somewhere in your Houston property you can't locate. Or Houston Water sent you a high-usage alert. These aren't coincidences — they're leak signals. Southern Eastern Texas's expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) soil puts constant stress on buried supply lines and slab foundations. We find the failure point before it becomes a structural problem.
Signs You Have a Hidden Water Leak in Houston, TX
Most Houston homeowners don't know they have a leak until Houston Water sends an alert or the bill arrives. By then it's been running for weeks. These are the early signals.
Our acoustic and thermal detection equipment finds leaks inside walls, under slabs, and underground — without opening anything first.

We specialize in leaks only — not general plumbing, not HVAC. Every service below uses specialist detection equipment before anything is opened on your property.
Slab Leak Detection — Houston
Slab leaks in Houston develop from two directions at once — expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) soil movement stresses the line from outside while hard water deposits corrode it from inside. In Southern Eastern Texas, this combination shortens the service life of copper supply lines significantly. We pinpoint the failure with acoustic detection before touching a single piece of concrete — you know exactly where the break is before we quote the repair.
Q: How do I know if I have a slab leak in my Houston home?
A: Watch for a warm or soft spot on your floor, a bill spike with no explanation, or a Houston Water usage alert. Southern Eastern Texas's expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) ground makes slab failures a known risk. Pressure testing confirms it in under an hour — we quote the repair before cutting anything.
Underground Leak Detection — Houston
Underground leaks in Houston are often the last ones homeowners suspect — because nothing inside the house is wet. The water loss happens entirely below grade, draining through expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) soil without leaving a surface trace. The only evidence is a running meter and a rising bill. We locate the failure with acoustic detection and pressure isolation before any digging happens.
Q: My Houston Water meter is running but nothing inside is wet — where is the leak?
A: A running meter with a dry house is one of the clearest underground leak signals in Houston. The water is going somewhere — just not somewhere visible. In Southern Eastern Texas's expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) conditions, it drains directly into the ground. We locate the failure point before any excavation starts.
Water Main & Service Line Repair — Houston
The service line between your Houston Water meter and your Houston home is homeowner-owned. When that line fails — from expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) soil stress, age, or seasonal ground movement — it's your repair and your bill until it's fixed. We locate the exact failure point before any digging, give you a fixed price, and complete detection and repair in one visit from one company.
Q: Who owns the water line between the Houston Water meter and my Houston home?
A: You do. Houston Water owns the meter, but the service line from the meter to your foundation is the homeowner's responsibility in Texas. A failure on that line is your repair — and every gallon lost counts against your bill until the repair is completed. We locate the failure and fix it in one visit.
Irrigation Leak Detection — Houston
An irrigation leak in Houston can run all season before anyone notices — the water drains into expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) soil immediately, leaving no surface evidence. The Houston Water bill is usually the first sign. We test each irrigation zone separately with pressure isolation, identify exactly which section is losing water, and pinpoint the failure before we open anything.
Q: How do you find an underground irrigation leak in Houston?
A: Zone-by-zone pressure isolation and acoustic detection. In Houston's expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) conditions, irrigation water drains away immediately — no puddle, no obvious wet ground. We test each zone separately, identify which section is losing pressure, then use acoustic equipment to pinpoint the failure before we start digging.
Bathroom, Kitchen & Ceiling Leak Detection — Houston
The stain on your Houston ceiling is showing you where the moisture arrived — not where the leak started. Water travels through framing and insulation before surfacing, so the visible stain and the actual failure are rarely in the same location. Thermal imaging traces the moisture path back to the source. We find it before you open the wrong wall.
Q: I have a water stain or wet area near my bathroom — what's causing it in Houston?
A: In Houston's slab construction, bathroom moisture most commonly traces to a supply line fitting failure, a cracked drain connection, or a failed shower pan. Thermal imaging locates the source before we open anything. Call before you tear out tile or drywall — the visible stain is almost never at the actual leak location.
Gas Leak Detection — Houston
Gas leaks in Houston are not a wait-and-see situation. We detect natural gas and propane leaks at the line, meter connection, and appliance fitting level using dedicated gas detection equipment. If you suspect a gas leak right now — leave the property immediately, do not touch any switches, and call 911 from outside before calling anyone else.
Q: What should I do if I suspect a gas leak in my Houston home?
A: Leave immediately without touching any switches or appliances. Call 911 from outside your property. Once the gas utility has shut off supply and cleared the address, call Leak Detection Pros to locate the exact failure point — at the line, fitting, or appliance connection — before service is restored to your Houston home.
Commercial Leak Detection — Houston
Houston commercial and multifamily properties face the same leak risks as residential — expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) soil movement, 1970s–2000s copper and CPVC infrastructure aging — but at scale. A slab or underground leak under a commercial property can go undetected longer because no single tenant tracks the meter. We provide full property surveys, pressure testing, and written reports for management or insurers.
Q: Do you handle commercial leak detection in Houston, TX?
A: Yes. We serve apartment buildings, retail centers, and HOAs across Houston and Harris. Commercial inspections include full property surveys, pressurized line testing, and written reports for management or insurance. We schedule around your tenants to minimize disruption to residents and operations.
Emergency Leak Detection — 24-Hour Response in Houston
A main line break in Houston loses hundreds of gallons before the water gets shut off. An active slab breach under a slab foundation can saturate the substructure within hours. We respond 24 hours, 7 days a week — emergencies in Houston are dispatched immediately, not scheduled for the next available slot.
Q: Do you offer 24-hour emergency leak detection in Houston?
A: Yes. We respond 24 hours for emergency situations — active flooding, main line failures, or sudden water loss in Houston. Call our main line and tell us it's an emergency. We serve Houston and surrounding Harris and dispatch same day, any day including weekends and holidays.
How We Find Leaks Without Tearing Up Your Houston Property
Four methods. We choose the right one based on the leak type, location, and Houston's specific soil and construction conditions — not a one-size-fits-all process.
Acoustic Leak Detection
Ground microphones amplify the sound of pressurized water escaping through expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) soil, concrete slab, and wall cavities. We hear the leak before we touch anything on your Houston property.
Thermal Imaging
Infrared cameras detect temperature differences caused by moisture behind slab walls and under floors. No cutting, no guessing — we see where the water is concentrated before opening anything.
Pressure Testing
We isolate sections of your supply line or irrigation zones and test for pressure drop. This confirms a leak exists and narrows its location before any excavation happens in Houston's expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) ground.
Tracer Gas Detection
For deep underground supply lines, we introduce non-toxic tracer gas into the pipe. It escapes at the failure point, rises through expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) soil, and our detector pinpoints the exact location — accurate to within inches.
Non-invasive detection — we find it before we open anything. Detection fee quoted upfront.

Why Houston Has Higher Leak Risk Than Most Markets
Most national plumbing companies apply the same approach everywhere. We don't. Houston's expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin) ground, slab construction, and 1970s–2000s copper and CPVC pipe infrastructure require a specific detection strategy. Here's why.
🌍 Southern Eastern Texas Soil: Expansive black clay (Houston) / caliche (San Antonio) / limestone (Austin)
Texas has some of the most expansive clay soils in the country — Houston's black clay and the Blackland Prairie move dramatically with wet-dry cycles, causing constant slab stress. Slab leaks are the dominant call type throughout most of Texas. February 2021 proved that Texas homes have no freeze protection — even a single hard freeze causes catastrophic pipe failures statewide.
🏗 Construction Type: Slab
Houston is a major metro with predominantly slab construction. In this construction type, supply line failures hide without visible surface signs until located with acoustic or thermal equipment.
🔧 Pipe Era: 1970s–2000s copper and CPVC
Homes built in the 1970s–2000s copper and CPVC period — common throughout Houston — have supply lines at or approaching end of designed service life. These lines corrode from the inside and fail silently before any surface sign appears at the wall or ceiling.
❄ Seasonal Risk in Southern Eastern Texas
Texas homes are built for heat, not cold — a hard winter freeze like February 2021 causes widespread pipe failures because exterior lines, attic lines, and slabs have no freeze insulation. Understanding this seasonal pattern is what separates a technician who knows Houston from one who's never worked in Southern Eastern Texas before.
