Leak Detection in Katy, TX
A water bill that jumped for no clear reason, a warm spot on the floor, or the sound of running water with every fixture off are the three most common reasons Katy homeowners call about a leak they can't see. Electronic leak detection finds the source without tearing out flooring or walls to go looking for it.
Water Bill Suddenly Higher, No Obvious Leak?
If nothing in the house looks or sounds wrong but the meter still shows water moving when everything is off, the leak is almost always underground or inside a slab, and it needs equipment to locate rather than a visual inspection.
Why This Happens in Katy
Katy sits on Gulf Coast clay soil that expands and contracts with wet and dry cycles, and that movement stresses slab plumbing over time, especially in older homes where the original lines have shifted along with the foundation. Newer homes in Cane Island and similar communities aren't immune either. A hidden leak behind a finished wall can go unnoticed for months in a home of any age.
Signs You Need Leak Detection
Unexplained High Water Bill
The meter shows usage even when every fixture in the house is off.
A Warm Spot on the Floor
Often a sign of a hot water line leaking under a slab.
Sound of Running Water
Audible even with all fixtures closed, usually inside a wall or under the slab.
Damp Baseboards or Carpet
Moisture showing up with no obvious source nearby.

How We Find It
A plumber isolates sections of the plumbing system by shutting off zones one at a time to narrow down where the leak is, then uses acoustic listening equipment to pinpoint the exact location by sound. Pressure testing confirms the finding before any flooring or drywall gets opened up.

Repair the Leak or Reroute the Line?
A Direct Repair Usually Makes Sense When
- This is the first leak found in the system
- The pipe material is otherwise in good condition
- Access to the leak point is straightforward
Rerouting Makes Sense When
- This is a second or third leak in an aging system
- The existing pipe material is failing broadly, not just at one point
- Repeated slab penetrations aren't practical
What Leak Detection Costs
Leak detection service typically runs $150 to $500. Slab leak repair itself runs $500 to $4,000+ depending on whether the repair is a direct slab penetration or a reroute above the slab.
Sudden, accidental water damage from a leak is sometimes covered by homeowners insurance. Gradual leaks and the underlying repair typically aren't. Check your policy's specifics. Want your real number? Call (281) 626-9205.
Scope, Honestly
We locate and repair leaks in residential plumbing systems, including under-slab lines. We don't perform foundation structural repair itself. If a leak has caused foundation movement, that's a separate scope we'll flag rather than take on.
What Governs the Repair
Slab and under-floor leak repairs follow the Uniform Plumbing Code (UPC) as adopted in Texas, which sets the standard for pipe materials, joint methods, and access requirements a repair has to meet, not just what gets the leak stopped fastest.
What to Check or Shut Off
If you can locate your home's main water shutoff, turning it off stops the leak from getting worse while you wait.
Avoid walking on a warm or damp spot on the floor repeatedly. It can be a sign of a hot water line under pressure.
Take a photo of the water meter reading before and after a period with everything off. It helps confirm the leak on the phone.
Don't cut into drywall or flooring yourself trying to find it. That risks cutting a line you can't see.
Common Questions
Acoustic listening equipment and pressure testing narrow the location without guessing, so nothing gets opened up until the source is confirmed.
Sometimes the resulting water damage is. The detection service and the underlying repair usually aren't. Check your specific policy.
Often yes for a straightforward, accessible leak. A slab penetration or reroute may need to be scheduled separately once the scope is confirmed.
It's worth ruling out. A plumber checks both the home's plumbing and, where relevant, the irrigation system before pinpointing the source, since the two are easy to confuse from the water bill alone.
Often Booked Together
A leak that turns out to be coming from the tank itself is a water heater issue rather than a hidden pipe, and a leak under a sink is often simpler, worth ruling out with faucet and sink repair first.
