Locating the leak precisely first means the repair opens one small area instead of searching.
Slab Leak Detection
Warm spots on your floor, the sound of running water when everything is off, unexplained water bill spikes. These are all signs of a slab leak. Electronic acoustic equipment is used to pinpoint the exact location without tearing up your floor first.
Wet spots, staining, or mold on walls and ceilings point to a leak inside the structure. The source is located before opening anything so the repair is minimal and targeted.
Once located, the leak is repaired using the method best suited to your home's plumbing, direct access repair, pipe rerouting, or epoxy lining, and restore everything to a sound, working condition.
Finding a hidden leak is detective work, and the goal is always the same: locate the exact spot before anyone opens a wall or breaks concrete. A plumber who guesses costs you twice, once for the wrong repair and again for the right one. Here is how a proper leak call goes from your first phone call to a finished repair.
1. Isolate the Source
The plumber shuts off fixtures and watches your water meter. If it keeps moving with everything off, water is escaping somewhere in the system. Pressure testing narrows it down to the hot line, the cold line, or the irrigation loop.
2. Pinpoint the Location
Acoustic listening equipment picks up the sound of water escaping a pressurized pipe, even through concrete. Thermal imaging finds the temperature difference a hot water slab leak creates. Together they narrow the location to within inches.
3. Review Options With You
Sometimes direct access repair makes sense, cutting a small opening at the leak. Other times rerouting the line overhead or epoxy pipe lining costs less than breaking the slab. You get the options, the prices, and the tradeoffs before anything starts.
4. Repair and Verify
After the repair the system is pressurized again and the meter is rechecked to confirm the leak is gone. Concrete and drywall are patched, and you get a clear explanation of what failed and why.
Because the leak is located before demolition begins, most repairs need one small opening instead of an exploratory search. If the leak turns out to be in your sewer or drain line rather than a pressurized water line, see sewer and mainline service instead. Typical costs are listed on our pricing page.
Warning Signs
Signs You Have a Hidden Water Leak
Pressurized water lines leak continuously, twenty-four hours a day, whether or not anyone is home. That is what makes them so expensive to ignore. A pinhole leak under a slab can release hundreds of gallons a week into the soil beneath your foundation before anything visible appears upstairs.
Riverside County homes face two conditions that make leaks more likely than average. Hard water leaves mineral deposits that corrode copper from the inside out, and expansive soil shifts with seasonal moisture, putting stress on rigid pipe joints. Homes built between the 1960s and the 1990s with copper run under the slab are the most common candidates.
A warm or unusually hot spot on a tile or concrete floor, which points to a hot water line leaking beneath it
The sound of running water when every faucet, toilet, and appliance in the house is off
A water bill that jumps significantly with no change in household usage
Cracks appearing in flooring, baseboards, or drywall as soil beneath the foundation shifts
A musty or mildew smell in a room with no visible water source
Low water pressure at fixtures that used to run fine
Damp carpet, discolored flooring, or paint that bubbles near the base of a wall
Any one of these justifies a call. Water damage compounds, and mold can establish inside a wall cavity within about forty-eight hours of sustained moisture. Catching a leak early is almost always the difference between a targeted repair and a restoration project.

A slab leak is a water leak in the supply lines that run underneath the concrete foundation of your home. They're common in older homes with copper pipes that have corroded. Warning signs include warm spots on your floor, running water sounds when nothing is on, unexplained water bill spikes, and cracking or buckling flooring.
Electronic leak detection equipment is used that listens for the acoustic signature of pressurized water escaping through a crack or pinhole. This lets us pinpoint the exact location, often within inches, without tearing open walls or floors first. After locating the leak, the most minimally invasive repair is planned.
Slab leaks get worse over time. Even a slow leak can erode the soil under your foundation, damage flooring and subfloor, promote mold growth in walls and under flooring, and dramatically increase your water bills. Early detection and repair is almost always cheaper than dealing with the secondary damage.
Electronic leak detection typically runs $150 to $500 depending on how much of the system has to be tested and how difficult access is. Repair costs depend on what is found and where it sits. An accessible pipe leak generally falls between $250 and $800, while a slab leak repair or reroute runs higher. See the full price estimate list for details, and you always approve the exact price before work begins.
Not always. Once the leak is pinpointed, there are usually several ways to fix it. Rerouting the affected line through the attic or walls avoids the slab entirely and often costs less than concrete work. Epoxy pipe lining can restore a pipe from the inside. Direct access through the slab is one option among several, and you decide which approach to take after seeing the prices.
Policies vary widely. Many California policies cover the resulting water damage and the cost of accessing the pipe but not the pipe repair itself, and coverage often depends on whether the leak was sudden or developed gradually. Document everything with photos, report it promptly, and ask your carrier directly. We can provide documentation of what was found and what was repaired.
Detection itself usually takes one to three hours. An accessible repair is often finished the same day. Slab leak reroutes and larger repairs can take one to two days depending on the length of pipe involved and how much patching is needed afterward.
