Why Washington County Property Owners Call Us First

Choosing a leak detection company in Washington, PA means more than hiring someone with the right equipment. Our technicians arrive on time, complete the inspection within the scheduled window, and leave the property clean. We treat every home and commercial space with the same care we’d expect for our own.

Our rigorous training program keeps our technicians among the most skilled in the industry. We continuously research and develop new detection methods, so the tools and techniques we use today are more precise than those available even a few years ago. Non-invasive leak detection services aren’t a workaround. They’re the standard we set.

The Systems We Inspect in Washington, Pennsylvania

Our proprietary detection technology locates leaks in pressurized plumbing, slab lines, walls, and underground systems without cutting into concrete or opening finished surfaces. Each system presents its own challenges.

Slab lines and underground pipes: Leaks here rarely announce themselves clearly. A slowly rising water bill or unexplained dampness near a foundation may be the only visible sign while water erodes soil or undermines a slab from below.
Wall leaks: Moisture trapped inside walls can go undetected for months, creating conditions for mold growth and structural damage long before discoloration appears on the surface.
Pressurized plumbing lines: These leaks may show up as reduced water pressure or unusually high usage, but pinpointing the exact location without our equipment typically means cutting into the system.
Sewer lines: Hidden sewer leaks carry health and environmental risks that make early, accurate detection essential.

Because we diagnose before any repair work begins, Washington County property owners receive a precise location report. That means a plumber knows exactly where to work, with no one opening walls or jackhammering concrete on a guess.

Get an Accurate Diagnosis Before Any Repair Work Begins

Our “Know Before You Go” approach means you receive honest, upfront pricing before we begin. No surprises, no pressure to authorize work beyond the inspection. Accurate leak detection helps prevent the unnecessary costs that come from missed diagnoses or exploratory demolition.

Call American Leak Detection of Pittsburgh at (412) 859-6000 to schedule leak detection service in Washington, PA. We can locate the problem precisely so you can move forward with confidence.

Signs You May Have a Hidden Leak

Some leaks make themselves obvious. Many don’t. Knowing what to watch for can mean the difference between catching a problem early and facing significant damage months down the line.

Unexplained water bill increases: A bill that climbs without a change in household habits often points to water leaving the system somewhere it shouldn’t.
Damp spots, warped flooring, or wall discoloration: These surface signs frequently indicate moisture that has been building behind finished materials for some time.
Running water sounds with no fixtures in use: Audible water movement when everything is turned off suggests flow somewhere in the plumbing system.
Musty odors or visible mold: Persistent moisture from a slow hidden leak creates conditions where mold can establish itself quickly.

If any of these signs are present at your Washington County property, a professional inspection is the fastest way to confirm whether a leak is the cause and where it’s located.

What Happens During a Leak Detection Appointment

When our technician arrives, they assess the property and plumbing system before selecting the appropriate detection method. We use acoustic and electronic detection equipment alongside our proprietary detection technology to isolate the leak’s exact location without opening walls, floors, or excavating landscaping.

Once the leak is pinpointed, we walk you through the findings clearly so you understand what was found, where it is, and what repair access will be needed. That information goes directly to your plumber or repair contractor, giving them a precise target rather than a general area to investigate.

See What Our Customers Say

"I highly recommend American Leak Detection!"
“We have a 30,000 gallon in-ground pool and have been loosing roughly 1/2" of water per day since we opened the pool this year. When I figured out how much water this really was, I freaked and called American Leak Detection asap. They showed up on-time, got to work and found a small fracture in the base of one of the return jets, and a small leak in the liner in the shallow end. Both repairs were explained in-detail how they be fixed and what I should look for and do in the future to make sure that the leaks would not return. The repairs were made, and now the water level is stable and no need for me to add any additional water. The guys were timely, professional, thorough, and communicated every step in the process. I highly recommend American Leak Detection!”

"Excellent Service"
“American Leak Detection Service arrived on a time. Jason was very professional and friendly, finding the leak very quickly. He did a very good job by checking intake and return lines, checking pool liner for leaks. He also gave great insight on how the problem could be fixed and offered to give an estimate on what it would take to fix the problem. Highly recommended!!”
