WHAT A SLAB LEAK ACTUALLY IS
Pinpointing and repairing pressurized water line failures beneath your concrete foundation — without unnecessary demolition.

PRESSURIZED SUPPLY FAILURE UNDER CONCRETE
Most homes across Corona, Riverside and the wider Inland Empire are built slab-on-grade: a single poured concrete pad, with the water supply lines run underneath it or cast into it. A slab leak is a failure in one of those buried lines. The water has nowhere to go but into the soil beneath your floor, or up through the concrete.
A slab leak is a pressurized supply line failure, not a drain problem. A blocked drain stops when you stop using the fixture. A slab leak runs continuously at mains pressure, 24 hours a day, until somebody shuts the water off.
Two lines can fail: the cold side or the hot side. Hot-side leaks are considerably more common because hot water accelerates corrosion and the pipe expands and contracts against the concrete with every draw. If you feel a warm patch on the floor, it is almost certainly the hot line.
Quick answer: Rooter King locates and repairs slab leaks — water lines leaking under the concrete slab — for homeowners across Corona and Riverside County, using electronic leak detection to find the leak before any concrete is opened. Rooter King is California-licensed under CSLB #1090875 and available 24/7.

COMPARE THE ACCESS AND RESTORATION SCOPE
Ask what the leak assessment establishes and why the proposed repair route is suitable. Compare pipe work, access openings and restoration separately. Confirm whether flooring, walls, concrete or other finishes are included in the same estimate. A written scope should identify the affected line and the completion checks, while any separate damage or insurance question is handled through the appropriate provider.
Non-Destructive Diagnostics
HOW WE FIND IT WITHOUT OPENING YOUR FLOOR
The old approach to slab leaks was to break concrete until you found water. That is not how this is done anymore, and you should not accept it. Locating comes first, and it is non-destructive.
Locating is a service in its own right — if you are not yet sure what you have, start with electronic leak detection and camera inspection. A confirmed location turns a vague, frightening problem into a defined job with a defined flat-rate price.

STEP 01
ISOLATE & PRESSURE TEST
We confirm the leak is under the slab and establish whether it is on the hot or cold side before touching any floor.
STEP 02
ACOUSTIC LISTENING
Ground microphones and amplified sensors pick up the acoustic signature of pressurized water escaping beneath concrete.
STEP 03
THERMAL IMAGING
Infrared cameras reveal invisible heat plumes through tile, laminate, or carpet to pinpoint hot-water manifold leaks fast.
STEP 04
LINE TRACING & SCOPE
Electronic pipe tracing maps the exact run geometry so we can compare spot repair vs. overhead rerouting accurately.
Diagnostics · What To Watch For
SEVEN SIGNS OF A SLAB LEAK
Slab leaks announce themselves indirectly. Any one of these on its own might be something else; two or more together is a strong signal.
- ⚠ 1. Warm Spot on the Floor
Tile or laminate noticeably warmer than surrounding flooring means hot water is escaping below. - ⚠ 2. Sound of Running Water
A faint continuous hiss near the floor or manifold when every fixture in the house is shut off. - ⚠ 3. Unexplained Water Bill Spike
A pressurized under-slab supply leak is metered water running 24/7 into the soil. - ⚠ 4. House-Wide Pressure Drop
Showers and faucets lose force across the house because water is escaping upstream. - ⚠ 5. Lifting or Cracked Flooring
Cupping wood, failing grout lines, or damp carpet where moisture wicks up through concrete. - ⚠ 6. Spinning Meter Indicator
If the low-flow triangle on your street meter turns with all fixtures off, water is escaping.

Repair Methods · Side by Side
FOUR WAYS TO REPAIR A SLAB LEAK — AND HOW TO CHOOSE
Once the leak is located, the right fix depends on pipe age, previous leaks, and where the failure sits. See our repiping and pipe repair and replacement guides for full system options.

1. Spot Repair
Open the slab at the exact located point, replace the damaged section, and patch the concrete.
Best when: First-time leak in newer, otherwise sound copper pipe.

2. Line Reroute
Cap and abandon the leaking under-slab manifold loop and route a new PEX-A or copper line through walls/attic.
Best when: You want that entire line out from under concrete permanently with zero jackhammering.

3. Whole-Home Repipe
Replace the aging under-slab supply system entirely with new overhead PEX-A or Type-L copper piping.
Best when: Repeat slab leaks or corroded pipes throughout the home.
4. Epoxy Pipe Lining
Line the existing pipe in place with a cured resin barrier where access is genuinely difficult.
Best when: Intact pipe geometry where wall or floor access is restricted.

LOCAL CONDITIONS · INLAND EMPIRE
WHY INLAND EMPIRE SLABS LEAK — AND WHY WAITING COSTS MORE
Western Riverside County combines four factors that drive under-slab failures: slab-on-grade tract construction, mineral-heavy hard water (which causes internal pinhole corrosion — solvable long-term with a water softener), expansive clay soils that shift seasonally, and hot-line thermal cycling against concrete sleeves.
- The water never stops: Pressurized lines run continuously until shut off at the main valve.
- Soil bearing loss & upward wicking: Saturated fill undermines slab support while moisture ruins tile, wood, baseboards, and drywall above.
- Contained fix vs. major restoration: Shutting the main valve and locating the leak early keeps a small pipe repair from turning into a flooring and mold remediation project.

FREQUENTLY ASKED QUESTIONS
How do I know it is a slab leak and not something simpler?
Run the meter test. Shut off every fixture and appliance in the house, then look at your water meter’s leak indicator. If it is still moving with the house completely off, water is escaping from the pressurised supply system somewhere. That does not prove it is under the slab, but it does prove you have a supply leak, and it is the single most useful piece of information you can give us before we arrive.
Do you have to break up my floor to find it?
No. Locating is non-destructive — acoustic listening, thermal imaging, pressure isolation and line tracing. Concrete only gets opened once we know precisely where the failure is and only if the chosen repair route calls for it. A reroute, for instance, involves no slab work on the new line at all.
Should I repair the one leak or repipe the whole house?
It depends on how old the pipe is and whether this is the first failure. A single leak in reasonably young, otherwise sound pipe is a spot repair, and it would be wrong to sell you a repipe for it. But if you have had two or three leaks in the same system, the pipe is telling you that it is failing generally rather than at one point, and continuing to chase individual leaks becomes the more expensive path. We will tell you honestly which situation you are in.
Is a slab leak covered by homeowners insurance?
That is genuinely between you and your insurer, and we will not tell you what your policy says. What we can say is that policies commonly treat the resulting water damage differently from the plumbing repair itself, and that documentation matters. We provide our findings and the location data in writing so you have something concrete to submit.
Can I shut the water off and just use it when I need it?
As a stopgap for a night, yes — shutting the main stops the loss and stops the damage clock. As a strategy it does not work, because every time you turn the water back on you are re-pressurising the failed line and putting more water under your floor. Treat it as a way to buy hours, not weeks.
Why do slab leaks so often turn up on the hot water line?
Three reasons stacking on top of each other. Heat accelerates the corrosion chemistry. The pipe expands and contracts with every hot water draw, abrading wherever it contacts concrete or a sleeve. And in homes with a recirculation loop, that line is moving hot water continuously rather than only when someone opens a tap. The cold line experiences none of that.
Will fixing the leak stop it happening again?
A spot repair fixes that spot. Whether the rest of the line follows depends on why it failed — a single mechanical fault is unlikely to repeat, whereas general corrosion through the whole system means the other sections are on the same trajectory. That is exactly what we assess while we are there, and it is the honest basis for choosing between a spot repair, a reroute and a repipe.
