Leak Detection in Arlington, VA

The Original Leak Specialist Serving Arlington, VA & Northern Virginia

American Leak Detection serves Arlington property owners as part of our DC and Northern Virginia territory. As The Original Leak Specialist, we locate leaks in pressurized plumbing, slab lines, walls, and underground systems using proprietary detection technology developed over more than 50 years because commercially available tools weren’t capable of doing this job without causing destruction. We find the leak first. Then we tell you exactly where it is.

A hidden water leak can sit undetected for weeks or months, quietly damaging walls, flooring, and structural elements the entire time. Waiting on a suspected leak doesn’t make the problem smaller. Our Leak Detection Without Destruction approach means we diagnose without demolition, helping protect your property throughout the process.

Leak Detection Services Available to Arlington Properties

We provide leak detection services for residential, commercial, and municipal clients. Each service category draws on the same proprietary detection technology and non-invasive methods.

Residential Services
We cover plumbing systems, pools, spas and fountains, and cause-and-origin investigations for homes in Arlington. If you’ve ruled out the obvious and still can’t find where a leak is coming from, a mystery leak investigation is the next step.

Commercial Services
Business properties face the same hidden leak risks as homes, often with greater consequences for operations and liability. Our commercial leak detection covers plumbing systems, pools, spas and fountains, and cause-and-origin investigations.

Municipal Services
We work with water distribution systems for municipal clients, applying the same non-invasive detection methods used across our residential and commercial services.

Smart Water Monitoring
Through our StreamLabs partnership, 24/7 smart water monitoring is available for property owners who want continuous visibility into their water systems between inspections.

Detection-focused service matters here. When the leak source is precisely located, repair contractors can address the confirmed problem area rather than conducting exploratory demolition followed by a repair.

Why Arlington Property Owners Choose American Leak Detection

General plumbers typically diagnose leak location by opening walls or excavating. Our technicians use acoustic, thermal, and pressure-based methods to pinpoint the source before any access point is made. That distinction isn’t incidental. It’s the entire service.

Our technicians complete a rigorous training program and work with proprietary detection technology we continue to research and develop. Non-invasive detection helps protect property values by avoiding unnecessary damage during the diagnostic process, and it can limit the scope of any repair work that follows.

Our Know Before You Go pricing approach means you receive honest, upfront pricing before work begins, with no unexpected charges. Technicians arrive on time, complete inspections within the given time frame, and leave your property clean.

Warning Signs You May Need a Leak Inspection in Arlington

Leaks in walls, slabs, and underground lines rarely announce themselves directly. These are the signals that warrant a professional inspection.

Unexplained water bill increase: A spike in usage costs without any change in habits is one of the most common early indicators of a hidden leak.
Water stains, damp flooring, or soft spots: Discoloration on ceilings, walls, or baseboards and warped or soft flooring point to moisture where it shouldn’t be.
Musty or moldy odors: Persistent odors that don’t resolve often mean moisture is accumulating in a concealed area.
Sound of running water with all fixtures off: Audible water movement when nothing is in use can indicate a pressurized line leaking inside a wall or slab.
Drop in water pressure: A noticeable drop across multiple fixtures can accompany a line leak somewhere in the system.
Unexplained pool or spa water loss: Water level drops that exceed normal evaporation rates suggest a leak in the shell, plumbing, or equipment.

What to Expect from a Leak Detection Service Call

Our process is built around finding the leak without creating new damage in the process. Here’s how that works in practice.

How We Locate the Leak

Our technicians arrive on time and use proprietary detection technology to investigate the suspected area. Depending on the situation, that may involve acoustic listening equipment, pressure testing, or thermal methods. Each approach is suited to a different leak type: pressurized plumbing, slab lines, walls, and underground systems each require a different technique, and our technicians carry the full range.

What Happens After the Leak Is Found

We don’t open walls or excavate to find a leak. The detection equipment locates the source first. Once the leak is confirmed and mapped, you receive a clear explanation of the findings before any repair work begins. That information goes to you and, if needed, to your repair contractor, who can then make a targeted access point rather than opening large sections of wall, slab, or yard. We complete the inspection within the given time frame and leave your property clean.

"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.”
