Cause & Origin Leak Detection

Professional Mystery Water Leak Detection Without Destruction™

A wet spot on the ceiling with no pipe above it. A mildew smell in a room with no visible moisture. Water appearing after rain in a place with no obvious connection to plumbing. These are the situations that bring homeowners to American Leak Detection for cause-and-origin leak detection when a standard inspection didn't yield an answer.

As The Original Leak Specialist™, we use proprietary detection technology, including infrared imaging, ultrasonic acoustics, and a systematic process of elimination to identify where water is coming from and why. The source gets confirmed without opening walls, pulling flooring, or guessing.

See What Our Customers Say

"So rare these days to find this kind of service. We feel so fortunate to have had them recommended to us by another plumber who felt like the job was too much for him."
“We were in a desperate situation. Our main water line into our house broke underneath the concrete slab of the house and flooded the bottom floor. We had to shut off all the water into the house. These guys found the broken pipe under the floor within inches of the break. Things got much more complicated from there, but to make a very long story short, they ended up putting a whole new water line into the house. Every step of the way they were working with us to figure out the cheapest way to fix the problem. What nice guys! I would recommend them to anyone I know. So rare these days to find this kind of service. We feel so fortunate to have had them recommended to us by another plumber who felt like the job was too much for him. I hope that it is a long time before I need this kind of serious work done again, but if I do, I will call these guys again.”

"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.”

We’re There When You Can’t Find the Source of a Leak

Not every water problem traces back to a plumbing failure. Some leaks move through structural materials, collect in hidden cavities, or enter from outside the building envelope entirely. If a general inspection or a basic repair didn't resolve it, a cause-and-origin investigation is the right next step.

Common situations our leak specialists investigate:

Water appearing on walls or ceilings without a visible source above
Mildew odor in a room with no identifiable moisture
Water entering after heavy rain, ground saturation, or snowmelt
Soft spots, buckling, or discoloration on floors and walls
Staining that reappears after drying or painting

If there's a leak present, we'll find it. Our leak specialists walk you through every finding so you understand the source and your options before any repair work begins.

Call (866) 701-5306 or submit a contact form to schedule your cause-and-origin inspection.

How We Use Infrared Detection for Mystery Leaks

One of the core tools in our cause-and-origin process is infrared detection. Our leak specialists use thermal imaging cameras to identify temperature differences within walls, ceilings, and floors caused by moisture intrusion. Water changes the thermal signature of building materials, and infrared imaging makes those changes visible without opening a single surface.

Common Mystery Leak Locations

Mystery leaks tend to originate from a predictable set of locations, even when water appears somewhere unexpected.

Within Walls and Ceilings

Water travels along structural members, insulation, and vapor barriers before it surfaces. A stain on a ceiling or wall often appears several feet from the actual entry point. Infrared imaging lets our technicians follow the moisture path back to the source.

Through the Foundation

Groundwater intrusion and hydrostatic pressure can force water through foundation walls, floor-to-wall joints, and below-grade slabs. This is common after prolonged rain or in areas with high water tables, and it is frequently misidentified as a plumbing leak.

Through Windows, Doors, and Roofing

Gaps in flashing, failed seals around window frames, and compromised roofing materials allow water to enter the building envelope and collect inside wall cavities. These leaks typically show up during or after rain, which leads many homeowners to assume the source is external when the actual entry point is a specific seal or penetration failure.

Under the Slab

Water lines running beneath a concrete slab can fail without any surface indication for weeks. The water dissipates into the surrounding soil before surfacing, and the first signs are often warm spots on the floor, a running meter, or an unexplained increase in your water bill.

Underground Service Lines

Your home's main service line runs underground from the municipal meter to the structure. When it fails, water does not always surface at the failure point or at all. It follows the path of least resistance, sometimes emerging at the foundation or in unexpected areas of the yard.

Mystery Leak Signs You Should Call a Leak Specialist

A previous inspection found nothing, but the signs keep coming back
Water staining or soft spots reappeared after a repair
Recurring mildew appears without a clear moisture source
Water appears after rain, snowmelt, or saturated ground conditions
Your water bill increased without a clear explanation

In the case that your insurance claim requires documentation of the cause and origin, rest assured our leak detection company always provides a documented report of findings after every inspection.

Many of these situations could have been caught earlier with smart water monitoring. Explore the possibilities with our systems today!

Frequently Asked Questions About Cause-and-Origin Leak Detection

What is cause-and-origin leak detection?

Cause-and-origin detection is the process of identifying both the location and the source of a water leak when it is not immediately obvious. Our technicians use infrared imaging, pressure testing, acoustic detection, and visual inspection in sequence to trace water back to its point of entry. This process is built for situations where a standard plumbing inspection has not produced a clear answer.

Can infrared detection find leaks inside walls without opening them?

Yes. Infrared cameras detect temperature differences in building materials caused by moisture. Water changes how materials retain and release heat, and those differences are visible in thermal imaging. Our technicians can identify moisture within walls, ceilings, and floors without removing any surface material.

Do you provide documentation for insurance claims?

Yes. Every cause-and-origin inspection includes a detailed report of our findings, including the identified source, the evidence collected, and the methods used to confirm the origin. This documentation is accepted by insurance adjusters and supports contractor scope development.

What if a previous inspection did not find the leak?

Cause-and-origin detection is built for exactly this situation. Our technicians use proprietary equipment and a systematic elimination process designed to find leaks that standard inspections miss. If a leak is present, we will find it.

How long does a cause-and-origin inspection take?

Most inspections are completed in a few hours. The timeline depends on the size of the property and the number of systems being evaluated. Your technician will give you a clear estimate before work begins.
