How Leak Detection Works
Our equipment locates the precise source of a leak, even through hard surfaces like concrete or slab foundations, using the same trenchless approach we apply across every service we offer, so we can pinpoint the problem without digging up your yard to search for it. Once we've found it, we assess how serious it is and address it at the source, whether that's a targeted repair or a larger fix like repiping.
Slab Leak Detection
A slab leak happens when a water or sewer line running underneath your home's concrete foundation starts to leak, usually from pipe corrosion, ground shift, or wear at a joint. Because the line is buried under the slab, you won't see it directly. You'll notice it instead through a warm spot on the floor if it's a hot water line, a sudden jump in your water bill, or the sound of running water when nothing's turned on.
We use acoustic and electronic listening equipment to trace the sound of the leak through the slab and pinpoint its exact location, without breaking up the whole floor to search for it. From there, the fix depends on what we find. Sometimes it's a direct point repair, and sometimes the line has deteriorated enough that trenchless pipe bursting makes more sense than patching the same failure twice.
What an Undetected Leak Actually Costs You
The EPA estimates the average household leak wastes more than 10,000 gallons of water a year. That's enough to run 270 loads of laundry. In about 10% of homes, leaks are bad enough to waste roughly 90 gallons a day. None of that shows up as a puddle in your yard. It shows up on your water bill.
Signs You May Have a Hidden Leak
A water bill that jumps with no obvious explanation is usually the first clue. Others include the sound of running water when every fixture is off, damp or unusually green patches in the yard, and a musty smell that doesn't trace back to anything visible. Any one of these is worth a call before the leak gets worse.
Why Choose US Trenchless
"After water started backing up into our toilet and bathtub, Abraham and the crew came to check it out that same day. They provided immediate action and a depth diagnostic. They later came back out to fix the outdoor pipes that had been damaged by tree roots and aging. They worked efficiently and a great price. Honest reliable work. Highly recommended!" — Gem R., Leak Location customer in Citrus Heights, CA
That kind of continuity isn't a one-off. Reviews spanning several years and dozens of jobs keep naming the same technicians by name, from leak detection calls to full sewer line replacements. That's the kind of team you're actually getting, not whoever happens to be available that week.
US Trenchless also holds California's highest-tier contractor license, the "A" General Engineering classification, rather than the more limited C-36 plumbing license most leak detection companies operate under. That license is what lets us take a job from the initial detection through the actual repair or replacement, without handing you off to a second contractor. We've held BBB A+ accreditation since 2017.

Leak Detection FAQs in Sacramento, CA
How much water can an undetected leak actually waste?
The EPA puts the average household leak at over 10,000 gallons a year, with the worst 10% of homes losing about 90 gallons a day. Most of that never shows up as visible water damage before it shows up on your bill.
How long does slab leak detection and repair take from start to finish?
Detection itself is usually quick since our equipment traces the leak's location without exploratory digging. The repair timeline depends on what we find: a direct point repair can often be done same-day, while a line that's deteriorated enough to need trenchless pipe bursting takes longer, though still without a full excavation.
If you find a leak in an old or damaged pipe, can you fix it the same visit?
Often, yes. Depending on what we find, that can mean a straightforward pipe repair, or if the pipe itself has deteriorated, trenchless pipe bursting to replace it without digging up your property.
