Leak Detection in Texas
Hidden leaks waste water and cause damage behind walls and under slabs. We use electronic leak detection equipment to pinpoint leaks without tearing up your property.
What Is Leak Detection?
Leak detection is the process of locating hidden water leaks inside walls, under concrete slab foundations, underground, or in other concealed areas without destructive exploration. Modern electronic leak detection uses acoustic sensors, thermal imaging cameras, and pressure testing to pinpoint the exact location of a leak before any digging or demolition begins.
Acoustic leak detection works by amplifying the sound of water escaping from a pipe. Even small leaks produce a distinct hiss or whoosh that trained technicians can isolate using ground microphones and contact sensors. Thermal imaging detects temperature differences caused by water saturating building materials — a wet area inside a wall or under a floor shows up as a distinct cold spot on an infrared camera.
Pressure testing involves isolating sections of the plumbing system and monitoring pressure gauges to determine which line is losing pressure and therefore leaking. This helps narrow down the leak to a specific pipe run before acoustic or thermal methods pinpoint the exact spot.
In Texas, slab leak detection is one of the most common and critical applications. The vast majority of Texas homes are built on concrete slab foundations with water lines running underneath. When these pipes develop leaks, the water has nowhere to go except into the soil beneath the slab, eventually surfacing as wet spots, foundation cracks, or unexplained spikes in the water bill. Professional leak detection saves thousands of dollars by locating the leak precisely so only a small section of slab needs to be accessed for repair.
Signs You Need Leak Detection
If you notice any of these symptoms, it's time to call a licensed plumber for professional assessment.
- ⚠Unexplained increase in your water bill — even a small hidden leak can waste thousands of gallons per month.
- ⚠Sound of running water when no fixtures are in use.
- ⚠Warm or hot spots on the floor — a hot water line leak under the slab.
- ⚠Cracks appearing in the foundation or walls — water erosion under the slab destabilizes the foundation.
- ⚠Mold or mildew smell with no visible source.
- ⚠Damp spots on walls, ceilings, or floors with no obvious cause.
- ⚠Water meter spinning when all fixtures are turned off.
Common Causes and Why This Happens
Understanding what causes the problem helps you make an informed decision about the best repair approach.
Corrosion of copper pipes from aggressive water chemistry — common in Texas hard-water areas.
Slab foundation shifting from expansive clay soils that stress pipe joints beneath concrete.
Joint failure from thermal expansion and contraction during Texas temperature extremes.
Pinhole leaks caused by water chemistry reacting with pipe material over years.
Failed connections at fittings, valves, or appliance hookups.
Root intrusion damaging underground water or sewer lines.

How Much Does Leak Detection Cost in Texas?
| Low | Average | High |
|---|---|---|
| $150 | $350 | $600+ |
Prices vary based on the specifics of each job. We provide a detailed, itemized estimate on site before any work begins — the price you approve is the price you pay.
Factors That Affect Cost
- •Type of detection needed — simple acoustic vs. full thermal and pressure testing.
- •Number of suspected leak locations.
- •Accessibility — open crawl space vs. finished basement vs. concrete slab.
- •Whether the leak is on the supply side or drain side of the system.
- •Follow-up repair scope — detection is usually billed separately from repair.
Benefits of Professional Leak Detection
Pinpoints the exact leak location without unnecessary demolition or excavation.
Saves thousands by limiting the access area needed for repair.
Identifies leaks before they cause structural damage, mold, or foundation problems.
Detects slab leaks that are invisible from inside the home but actively causing damage.
Provides documentation useful for insurance claims and home sale disclosures.
Expert Tip
Check your water meter once a month with all fixtures turned off. If the flow indicator is moving, you have a leak somewhere in your system. Catching it early through this simple check can save you from a much larger — and more expensive — problem later.
