Non-Invasive Leak Detection for Katy Homes, Businesses & Municipal Properties

American Leak Detection of Houston is The Original Leak Specialist™, with more than 50 years as the national company that originated non-invasive leak detection. We built our own proprietary detection technology because nothing commercially available could locate hidden leaks without tearing into the property. That principle, Leak Detection Without Destruction™, guides every service call we make in Katy and across the greater Houston area.

Hidden water leaks can run for weeks or months beneath slabs, inside walls, and underground before a single surface sign appears. By the time something is visible, damage may already be extensive. We find the leak precisely and leave your property intact.

Suspected a leak in your Katy home or business? Call us at (281) 941-2489 or request a service call online. Our leak specialists can confirm the source before any repair work begins.

Why American Leak Detection of Houston Is Different from a General Plumber

Most plumbing companies offer leak detection as a secondary service, using off-the-shelf equipment that wasn’t designed for the job. We built our own tools specifically because that equipment couldn’t locate leaks without causing destruction. Our leak specialists complete a rigorous training program and focus exclusively on detection, not repair, so their entire effort goes toward finding the precise leak location.

Our technicians arrive on time, finish within the stated timeframe, and leave the property clean. Before any work begins, you receive honest, upfront pricing through our Know Before You Go approach. No surprises, no pressure.

Leak Types We Locate in Katy

We locate leaks across every major hidden leak category: pressurized plumbing, slab leaks, walls, and underground systems. Whether the source is a supply line beneath your concrete foundation, an in-wall fitting failure, or a break in the water main between the meter and your structure, our non-invasive methods apply. No speculative wall openings, no unnecessary excavation, no slab cutting until the leak location is confirmed.

Drain and sewer line breaches require different diagnostic methods than pressurized water line detection. Our leak specialists are trained across both categories, so we can identify which system is the source before any physical access is attempted. We serve residential, commercial, and municipal properties throughout the Katy area.

Katy’s Soil & Infrastructure Conditions

Katy’s expansive clay soil shrinks during dry periods and swells when saturated, creating cyclical stress on buried pipes, slab penetrations, and underground water mains. That repeated movement accelerates wear and increases the likelihood of cracks or joint failures over time. Most communities outside the incorporated city limits are served by Municipal Utility Districts rather than a single utility provider, so infrastructure age, pipe material, and maintenance standards vary across Harris County and Fort Bend County. Katy is also undergoing a regional transition from groundwater to surface water delivery through a new pump station on Fry Road, a change that may affect corrosion rates in older plumbing systems.

Schedule Leak Detection Service in Katy

A suspected leak doesn’t get smaller on its own. Hidden water damage can compound with every passing day, and the longer a leak runs, the broader the repair may become. Call American Leak Detection of Houston at (281) 941-2489 to speak with a leak specialist and schedule service in Katy.

Warning Signs of a Hidden Water or Sewer Leak

Catching these indicators early can limit damage before it spreads. These are the most common signs that a hidden leak may be active in your home:

Unexplained water bill increases: A spike in your monthly bill with no change in usage is one of the most reliable early signals of a hidden water leak.
Warm or damp floor spots: Warm patches on tile or concrete, particularly in slab-foundation homes, can indicate a hot-water supply line leaking beneath the foundation.
Drywall staining or soft spots: Discoloration or soft areas near floor level or on ceilings suggest a slow in-wall leak that has saturated surrounding material.
Sound of running water: If you hear water moving when every fixture and appliance is off, or if your meter dial continues moving after everything is closed, active water loss may be occurring somewhere in the system.
Musty or sewer-like odors: Indoor odors without an obvious source may indicate a drain or sewer line breach rather than a supply line issue.
Soggy or unusually green yard patches: Saturated or lush areas unrelated to irrigation can indicate an underground water main leak between the meter and the structure.

The Four Hidden Leak Categories

Each leak category behaves differently and requires a different diagnostic approach. Understanding where leaks occur helps explain why professional detection matters.

Slab Leaks

Slab leaks occur when a supply or drain line beneath a concrete foundation develops a breach. Symptoms can include warm floor patches, the sound of running water, gradual foundation movement, and elevated water bills. Because the pipe is beneath concrete, accessing it without prior confirmation can mean significant unnecessary destruction.

In-Wall Supply Line Leaks

In-wall leaks typically stem from fitting failures at plumbing rough-ins or valve connections. A slow drip into the wall cavity may not produce visible surface staining for weeks, allowing moisture to accumulate in framing and insulation long before the problem is apparent.

Underground Water Main Leaks

A break in the water main between the meter and the structure causes yard saturation, pressure drops at every fixture, and continuous meter movement even with everything shut off. Confirming the breach location before digging can help prevent unnecessary excavation across the yard.

Drain & Sewer Line Breaches

Sewer line failures often present as slow drains, recurring clogs, sewer odors, or ground settling above the buried line rather than as visible water. Detection methods for drain and sewer lines differ substantially from those used for pressurized supply lines, which is why training across both categories matters.

How Non-Invasive Leak Detection Works

Our proprietary detection technology was developed over more than 50 years specifically because off-the-shelf equipment couldn’t locate leaks without causing property destruction. Nothing is opened, cut, or excavated until the leak location is confirmed. That’s what separates professional non-invasive detection from speculative exploratory access.

The methods we use include acoustic listening devices that amplify the sound signature of pressurized water escaping from pipes, thermal imaging to identify temperature differentials caused by water movement behind walls or under slabs, electronic line tracing to map buried pipe routes, and pressure isolation testing to confirm and localize a leak to a specific pipe segment.

Residential, Commercial & Municipal Service

We serve the full range of property types throughout the Katy area. For residential properties, non-invasive detection protects the home from unnecessary damage during the process. Commercial properties and multi-unit buildings face compounded exposure from hidden leaks: a single undetected source can affect multiple tenant spaces, damage inventory or equipment, and go unnoticed longer in lower-traffic areas. Municipal and institutional properties benefit from non-invasive methods because access restrictions and business continuity requirements make exploratory digging or wall access impractical.

The Cost of Waiting on a Suspected Leak

A hidden water leak can cause structural damage to framing, subfloor, and foundation well before any surface sign appears, and the longer it runs, the broader the repair scope may become. Mold growth may begin within 24 to 48 hours of sustained moisture exposure in a wall cavity or under flooring, potentially adding remediation cost on top of the original repair. Water waste from a continuous hidden leak also accumulates on utility bills over weeks or months. Early detection can limit the financial exposure on both sides.

What to Expect During a Service Call

When you contact us, you’ll receive upfront pricing through our Know Before You Go approach before any detection work begins. Your leak specialist arrives on time, conducts a thorough non-invasive assessment using the appropriate detection methods for your situation, and confirms the exact leak location. The project is completed within the stated timeframe, and the property is left clean. You’ll also receive clear documentation of the confirmed leak location, which can support an insurance claim if your policy covers detection or repair costs. Coverage and terms vary by policy, so confirm the details with your insurer.

See What Our Customers Say

"The only plumber you should call..."
“Rick and his team provided EXCELLENT service and performed great work in what would have otherwise been a very challenging, stressful situation. There was a leak under our foundation, but with one call to American Leak Detection an incredibly professional team arrived, located the leak, and started repairs. Rick provided updates throughout the process so we knew what needed to happen and why. The pricing was fair and transparent and the work was completed on time (the weather didn't co-operate, but Rick and his team found a way). Major plumbing repairs can be incredibly stressful for any homeowner but ALD made the process a whole lot better. Based on the work and care American Leak Detection took with my home, this is the only plumbing company I would ever call.”

"I won't hesitate to call or recommend American Leak Detection.....what a great crew"
“WOW, just when you think that the problem with your leaking Spa is going to be a nightmare, along comes American Leak Detection. My Pool and connecting Spa is about 40 years old. The Spa when in operation began to leak. Looked up leak vendors, American Leak quoted a fair price to locate the leak and was able to come out quickly. Shawn, American Leak technician showed up on the time agreed to. Very professional and at the same time friendly explaining in detail what he had found, what had to be done and reduced the agreed price because he identified the issues quickly...…..really, I intended on paying the full amount. He also quoted a price for the necessary repairs again, explaining in detail how and what has to be done by the repair crew. He left the proposal with me without any pressure to move forward and that all I needed to do if I decided to move forward was to schedule the repair with the main office....so far a very pleasant ordeal. I did indeed call the main office the next morning and scheduled the repair. Again on time Casey and a helper arrived for the repair. Casey kept me informed through the entire process. He actually found that all three of my "Jets" were broken/leaking. Both Casey and his helper were a pleasure to interface with. They made the repairs in an expeditious manner. The repairs required Casey to completely penetrate the Spa gunite wall for all three Jets making a hole about 8" square for each. Additionally it required two 8" square holes through my cool deck. That being said I was extremely worried about matching the color of the plaster in the Spa as well as the grey cool deck color. Casey assure me that he would be able to do so pretty good......I was skeptical...….I was wrong to be......Casey was right...………….What an outstanding job and a pleasant experience for me...….my worries were all for nothing...……..I won't hesitate to call or recommend American Leak Detection.....what a great crew...….but wait it didn't end there.....I still had to pay the invoice that was left after Casey and his helper were done...….so I called to pay the invoice and Talked to Heather Riley.........….What can I say just another breath of fresh air....."cudos" to the entire American Leak Detection team...….”
