For Chicago property owners
Mystery and hidden leaks tend to happen as a result of complicated building modifications or aging infrastructure unique to this region. The high ambient moisture in the basement area confuses homeowners about the source of the water. Our inspection analyzes the whole area to distinguish between condensation and plumbing leaks.
Our technology
Advanced, non-invasive leak detection equipment
We locate the leak first, so repairs open only what needs opening. No guesswork, no unnecessary demolition.
Thermal imaging cameras
Infrared imaging reveals temperature differences behind walls and under floors caused by escaping water.
Acoustic listening
Amplified ground microphones pick up the sound of pressurized water leaking through concrete and soil.
Moisture meters and mapping
Readings in drywall, wood, and concrete trace moisture back toward its source.
Video pipe inspection
Flexible cameras inspect drain and sewer lines for breaks, offsets, and root intrusion.
FAQ
Questions about mystery / hidden leak detection
Why couldn't someone find my leak before?
+
Water always moves until it becomes visible. Mystery and hidden leaks involve the examination of multiple sources of water rather than just the closest pipe.
Is it always a plumbing leak?
+
No. Condensation, roof, window, and grading can cause moisture. The inspection helps to determine the most probable source of the leak.
What should I tell the technician?
+
Let the technician know when the problem was noticed, where the water is visible and whether it varies with weather and water usage.
Can an intermittent leak be found?
+
Yes. Testing different conditions such as the use of specific fixtures helps to determine the leak.
