Leak Detection in Carrollton, TX

Non-Invasive Detection for Slab, Wall & Underground Leaks

American Leak Detection is The Original Leak Specialist™, serving Carrollton homeowners and businesses as part of our North Texas service area. Backed by 35 years of experience in North Texas and a national brand with over 50 years of history, we built our own proprietary detection technology because nothing available on the market could find leaks without tearing into walls, floors, or foundations. That commitment still defines every service call we make.

Hidden leaks in pressurized plumbing, slab lines, walls, and underground systems can run for weeks or months before visible damage appears. In Carrollton, where a large share of homes were built on slab foundations over expansive Blackland Prairie clay soil during the 1970s through 1990s, aging supply lines under concrete face real stress. Finding the leak precisely before anything is disturbed isn’t just our approach. It’s our discipline.

If you’re seeing signs of a hidden leak, don’t wait for the damage to grow. Call American Leak Detection at (866) 701-5306 or request a service call online to schedule your leak inspection in Carrollton.

Leak Detection Services We Provide in Carrollton

We locate leaks across a wide range of systems for both residential and commercial properties. Whether you’re dealing with a spike in your water bill, moisture behind a finished wall, or a buried line you can’t trace, our Leak Detection Without Destruction™ approach identifies the source before any concrete is cut or drywall removed.

Our Carrollton leak detection services cover:

Slab leak detection: Locating breaks in supply or drain lines running beneath concrete foundations without disturbing the slab
Wall leak detection: Identifying moisture sources behind finished surfaces using non-invasive methods
Underground pipe leak detection: Pinpointing breaks in buried supply or service lines before any excavation is planned
Drain leak detection: Addressing leaks in drain lines that may not register on a water meter but can cause structural damage and mold growth
Pool, spa & fountain leak detection: Non-invasive leak location for pool and spa systems
Smart Water Monitoring: Ongoing leak monitoring through our StreamLabs program
Commercial leak detection: Detection services for commercial properties and multi-unit buildings

We also offer cause and origin investigations and programs designed for property managers and insurance adjusters who need documented, claim-ready service reports.

A Detection Professional, Not a Generalist Plumber

Most plumbers treat leak detection as a step before the real work begins. For us, precise location is the work. We developed our proprietary detection technology because off-the-shelf equipment couldn’t locate leaks without causing destruction. That technology, refined over more than 50 years nationally, is what separates us from generalist plumbers operating in Carrollton.

For Carrollton homeowners navigating a homeowner’s insurance claim after a slab or hidden leak, our professional documentation of the leak location and cause can support the claims process. Our customers consistently describe our technicians as thorough, prompt, and clear about explaining what they found and why.

Schedule Leak Detection in Carrollton Today

A hidden leak doesn’t stop moving while you wait. Water migrating through or around a slab can compromise your foundation, promote mold growth, and drive up your utility bill with every passing day. The sooner the leak is located precisely, the more limited the damage may be, and the simpler the repair may be.

Call American Leak Detection at (866) 701-5306 to schedule a Carrollton service call, or request an appointment online. We can locate your leak without destroying your property to find it.

Warning Signs of a Hidden Leak in Your Carrollton Home

Slab and underground leaks rarely announce themselves with obvious flooding. The early signals tend to be subtle, and in Carrollton’s aging housing stock, they’re easy to attribute to something else. These are the indicators worth taking seriously:

Unexplained water bill increases: A pressurized slab or underground leak runs continuously, showing up as a steady or sudden spike in monthly usage
Warm spots on the floor: Hot water supply lines leaking beneath the slab can create noticeable temperature differences at floor level
Sound of running water with all fixtures off: Audible water movement when nothing is in use points to a pressurized leak somewhere in the supply system
Low pressure at multiple fixtures: Simultaneous pressure loss across the house often indicates a supply leak upstream, frequently under the slab
Moisture at baseboards or musty odors: Water migrating up through or around the slab can appear as damp baseboards, discoloration, or a persistent musty smell near floor level
Sticking doors, cracking tile, or new wall cracks: Long-running hidden leaks can saturate Carrollton’s expansive clay soil unevenly, causing foundation movement that shows up as structural symptoms throughout the home

How Non-Invasive Leak Detection Works

Leak Detection Without Destruction™ is possible because of how the search is conducted. Rather than opening walls or breaking concrete to find a suspected leak, we isolate and identify the source using precision methods before anything is disturbed.

Pressure isolation testing: Identifies which branch of the supply system is losing pressure, narrowing the search area to the affected line before any surface work begins
Acoustic detection: Sensitive equipment detects the sound signature of water escaping under pressure through concrete or soil, pinpointing the break without disturbing the surface above
Thermal imaging: Identifies temperature differentials at floor or wall surfaces caused by leaking water below, adding a second data point for hot-water line breaks

Knowing the exact location before any repair decision is made means the method chosen matches the actual failure point, protecting your slab, flooring, and walls from unnecessary work.

Why Carrollton Homes Face Elevated Leak Risk

Carrollton’s growth from the 1970s through the 1990s left the city with a large share of homes on concrete slab foundations over Blackland Prairie clay soil. That clay expands with rainfall and contracts during dry periods, placing cyclical stress on buried plumbing connections year after year. Copper and galvanized supply lines installed during that era are now at the age when pinhole failures and joint separations become more common.

A significant portion of Carrollton homes were built on post-tension slab foundations reinforced with high-strength steel cables embedded in the concrete. Locating any break without disturbing the cable grid is essential in these homes. Cutting into a post-tension slab without precise location first can compromise structural integrity, which is exactly the scenario our non-invasive approach is designed to prevent.

Carrollton also spans Dallas, Denton, and Collin counties, where permit requirements can vary depending on which county a property sits in. Knowing precisely where the leak is before any repair work begins keeps that process straightforward from the start.

"They showed up on time and gave good advice with a fair price."
“This is a fair and honest company. They showed up on time and gave good advice with a fair price. They can be trusted to give accurate information.”

- Alda F.
"They came in, investigated with smoke, and fixed the problem. For the first time in two months, my house doesn't smell like a restaurant toilet."
“I had an awful rotten egg smell as soon as I bought our house. After calling two plumbers (who charged me a fee to tell me nothing was wrong), the Gas Company (no gas leak), and the Public Works Department, I finally called American Leak Detection. They came in, investigated with smoke, and fixed the problem. For the first time in two months, my house doesn't smell like a restaurant toilet. Highly recommend them!”

- Sandi T.
"I can't say enough good things about their service!"
“I can't say enough good things about their service! We had a slab leak that flooded the master bedroom and they came as quickly as they could and then rearranged their work schedule so the repair could be made and we could once again have water turned on. The workmen were professional and efficient. I hope I never have to use that kind of service again but if so, they are he best.”

- Carolyn R.
"After 30 years in this house, we have had many service people come to do work. No one has ever delivered better than Daniel."
“Tree roots had cracked my filter pipes and I was losing water badly. I was referred to American Leak Detection and set up an appointment. Daniel came out and did his best to diagnose the problem. He got very strange results and it was hard to determine the exact pipe(s) that were cracked but since I'd had a similar repair done 6 years ago and we could see evidence of the tree root damage from above, I felt confident we knew were the issue was and I contracted for the work. I was pleasantly surprised to see Daniel return to perform the work. I arranged to be home that day so I could see what he found. I supposed I hovered, taking pictures of the process, asking questions as he went along. He never got annoyed and answered every question with a smile. I don't think i ever saw anyone work harder. It was obvious from that start he had a lot of experience and knew what he was doing. Digging out the area had to be done mostly by hand which he did efficiently without complaints. He found multiple pipes cracked which explained the odd results during diagnosis. The job took longer than expected because it was difficult work and he ran out of daylight but on the job until he it wasn't possible anymore that day. Even though he was fully booked for the following day, his company rearranged his schedule so he could return the following afternoon. I returned home early from work and was able to see him complete the job. He even patched the deck with new concrete like an artisan, taking every care to make it as smooth and neat as possible. After 30 years in this house, we have had many service people come to do work. No one has ever delivered better than Daniel. He was competent, diligent, and pleasant. The cost wasn't cheap but it was fair. I don't mind at all paying for quality service.”
