Symptoms and Warning Signs
- A water bill climbing month over month with no change in how you use water
- The sound of water running when every fixture in the house is off
- A warm patch underfoot, often a sign of a hot-water line leaking under the slab
- A floor spot that stays damp, soft, or discolored
- Musty odors, creeping stains, or paint bubbling on a wall
- A water meter dial that keeps ticking over with all fixtures closed
- Weaker pressure showing up alongside moisture you cannot explain
- Cracked or lifting flooring over a slab with no obvious cause
Common Causes
- Pinhole corrosion working through aging copper or galvanized supply lines
- A failed fitting hidden inside a wall or ceiling cavity
- A slab leak in a supply line run beneath the foundation
- Deteriorated seals at connections buried out of sight
- Sustained high pressure stressing older, thinner-walled pipe
- Ground movement in the region's expansive clay soil stressing under-slab lines
- An earlier repair that treated the symptom but never found the source
What to have ready when you contact us
Our Inspection & Diagnostic Process
- 1Review the symptoms, recent water bills, and how the meter is behaving
- 2Confirm a leak is actually present with a meter and pressure check
- 3Isolate the system in zones to narrow where the leak is hiding
- 4Use acoustic listening and moisture and thermal tracing to pinpoint the source
- 5Mark the exact spot so any access opening stays small
- 6Recommend the repair path and confirm the leak is fully accounted for

Why Professional Help Matters
Guessing where a hidden leak lives means opening walls or slab you never needed to touch, and every wrong cut is time, mess, and repair on top of the leak itself. Proper detection narrows the source to a small area before a single cut is made, so the repair is targeted and the patch-and-paint afterward is minimal. The tools matter: a pressurized line makes a continuous high-frequency sound that an acoustic sensor can isolate even through soil and concrete, while a hot-water slab leak leaves a temperature signature a thermal camera can read, and the two together place a leak that neither would find alone. Detection also settles whether the moisture is a supply leak, a drain leak, or plain condensation, and each of those calls for a completely different fix, which is why finding the source first is what keeps you from paying to solve the wrong problem.

Sacramento's mix of slab-on-grade tract homes and older raised-foundation houses means leaks hide in very different places from one block to the next, from under poured concrete to deep in a crawlspace. Aging copper and galvanized supply lines in the city's older neighborhoods are especially prone to the pinhole corrosion that makes a slow, hidden leak, and the region's expansive clay soil shifts with the wet and dry seasons in a way that stresses the lines running beneath a foundation. All that slab construction is exactly why accurate slab-leak location earns its keep here: opening concrete in the wrong spot is costly and slow to put back, so pinpointing the leak with acoustic and thermal tools before anyone takes a saw to the floor protects both the foundation and the budget.

Frequently Asked Questions
The common tells are a water bill that keeps rising, the sound of water running with everything shut off, damp or oddly warm spots on the floor, and a meter dial that will not sit still with all fixtures closed. Any one of those is worth investigating before it turns into rot or a mold problem.
We start by confirming a leak exists with a meter and pressure test, then isolate the plumbing in zones to narrow the area. From there, acoustic listening picks up the high-frequency sound of water escaping a pressurized line, even through concrete, and thermal imaging reads the warmth of a hot-water leak. Together they mark a small, precise spot rather than a general area.
That is the whole point of the service. Using pressure testing, acoustic listening, and thermal and moisture tracing, we locate the source and mark a small area so the eventual repair opening is as targeted as it can be, rather than exploratory holes across a wall or floor.
It is a leak in a water line running beneath the concrete foundation, common in Sacramento's slab-built homes. Because you cannot see it, we locate it from the surface with acoustic sensors and, for hot-water lines, thermal imaging, then mark the exact point so any concrete that has to be opened is opened once and in the right place.
Not always. It can be condensation, a roof or window issue, or a drain leak rather than a pressurized supply leak. Detection tells us which one you actually have, so you spend money fixing the right problem instead of repairing a pipe that was never the cause.
It varies with the size of the home and how much acoustic and thermal work the leak takes to pin down, and a straightforward location costs less than a stubborn slab leak that needs several methods. We give you the scope upfront, and because the goal is a small, accurate repair opening, good detection usually saves more than it costs in avoided demolition.
We show you exactly where it is and lay out the repair path, whether that means a pipe repair, a fitting replacement, or slab-leak work, so you can decide with the full picture in front of you rather than committing blind.
