Leak detection — find the hidden leak before it finds your floors.
Undetected leaks in water, gas, or sewer lines quietly run up your bill and damage your home. We locate them precisely — without tearing your walls or slab apart — using thermal imaging, acoustic tools, and specialty gas sensors, then help you stop the next one.

Everything we do
Our leak-detection toolkit
Our non-invasive toolkit
We find leaks without tearing your home apart — acoustic listening, pressure testing, thermal imaging, moisture mapping, and smoke or gas sensors, matched to the job.
Find it — and stop the next one
Beyond finding today’s leak, we install smart automatic shut-off systems like the Moen Flo that watch your main line around the clock and shut the water off before a small leak becomes major damage — ideal for second homes, rentals, and wineries.

Leak detection questions, answered
How do you find a leak without tearing up my house?
Thermal imaging, acoustic listening, pressure testing, and gas sensors let us pinpoint the source behind walls and under slabs before any opening is made.
What’s a slab leak, and how do you find it?
A leak in a water line under the concrete foundation. We locate it with thermal and acoustic tools so the repair targets just that spot — not the whole floor.
Do you detect gas leaks too?
Yes — natural gas and propane, with specialty sensing equipment. If you smell gas right now, leave the building and call your gas utility first, then call us.
What’s a whole-home shut-off, and is it worth it?
It’s a smart valve like the Moen Flo installed on your main line. It monitors flow around the clock and shuts the water off automatically when it senses a leak. For second homes, rentals, wineries, and anyone who’s had water damage before, it’s well worth it.
