California Plumbing Service specializes in exactly that. We confirm the leak, pinpoint it with acoustic listening and thermal imaging, and repair it — either with a targeted spot fix or a full reroute of new piping overhead. Every option comes with upfront pricing and 24/7 emergency service, and we serve every corner of Costa Mesa.
The Mesa Water Factor
Here's something most Costa Mesa homeowners don't know: Mesa Water District is the only water district in Orange County that meets 100 percent of its customers' demand with locally sourced groundwater. That water comes from a deep aquifer — some of it 12,000 years old, tinted amber by ancient redwood remnants before treatment removes the color. It's a remarkable supply story, and it means Costa Mesa's water chemistry is consistent year-round.
Consistent doesn't mean gentle on old copper, though. Decades of water flow, thermal expansion, and the occasional aggressive soil condition still thin buried lines. In Mesa Verde's ranch homes, Eastside cottages, and Westside bungalows alike, the failure pattern is the same: a pinhole leak that runs silently for weeks before symptoms surface.
Spotting a Slab Leak Before It Spreads
The earliest sign is often financial — a water bill that climbs with no change in habits. Then come the physical clues: a warm patch on the floor, the sound of water running behind walls, damp carpet at the edges, or tile that suddenly feels loose. Outside, a mysteriously green strip of lawn can mark where water is surfacing.
Don't wait for confirmation. A pressurized leak erodes the soil under your slab around the clock, and moisture wicking upward ruins flooring, baseboards, and drywall. We serve Mesa Verde, Eastside Costa Mesa, the Westside, South Coast Metro, and College Park, and we treat every suspected slab leak as urgent — because the damage never pauses.
When a Reroute Beats a Spot Repair
A single pinhole in otherwise solid copper is a straightforward spot repair: open a small section of slab, replace the bad segment, restore the concrete. But when our inspection reveals widespread green corrosion or thin walls along the line, we recommend a reroute — abandoning the buried pipe and running new PEX or copper through walls and attic.
Reroutes cost more upfront and save far more over time. No more jackhammering the next time a weak spot gives way, and the new line runs where future repairs take minutes instead of days. For Costa Mesa's aging tract plumbing, it's often the last pipe job the house will ever need.

Frequently Asked Questions
How do I know the leak is under the slab and not somewhere else?
We prove it before opening anything. By shutting off fixture groups and watching the water meter, we isolate the leak to the buried lines. Acoustic sensors then confirm the location underground. If the meter holds steady, the problem is elsewhere — and we'll tell you that honestly rather than selling a slab repair you don't need.
Is a reroute really better than fixing the leak?
When the pipe is broadly deteriorated, yes. A spot repair fixes one hole; a reroute replaces the entire failing run with new pipe in an accessible location. For 50-plus-year-old copper showing corrosion in multiple places, rerouting ends the cycle of repeat leaks and repeat concrete work.
Will you have to tear up my flooring?
Only a small area for a spot repair, and we restore the concrete afterward — though matching existing flooring is your flooring contractor's job, and we'll be straight about that. A reroute avoids the slab entirely, running new lines through walls and attic with minimal drywall patches.
Does homeowner's insurance cover slab leaks?
Often the resulting water damage is covered while the pipe repair itself isn't, but policies differ. We document everything — meter readings, photos, thermal images, and a written diagnosis — to support your claim. Review your policy's plumbing and water-damage sections before assuming either way.
