Laguna Beach Slab Leak Detection & Repair
About six in ten Laguna Beach homes went up before 1970, and more than a quarter before 1950. Copper that old wears thin, and a leak under the concrete often shows up first as a warm spot on the tile. Laguna Beach slab leak detection pins down the failed line with no digging. Free leak detection when you proceed with us for the repair, and a technician can be at your door within 60 minutes.

Before you call: we handle the water lines that feed your home, whether they run in the slab, under the foundation or inside a wall. Pool and spa leaks, irrigation lines and natural-gas lines are outside what we do.
Older homes, older copper under Laguna Beach floors
Laguna Beach climbs fast. The land rises from the shoreline into the hills and canyons of the San Joaquin Hills, and Temple Hill, in the Top of the World neighborhood, reaches 1,007 feet. A slab leak is a leak in a water line buried in the concrete floor. Whether your home sits near the sand or up a canyon, the signs are the same: a warm patch of floor, a meter that turns with everything off, or a bill that keeps climbing.
The houses are old, too. The typical home in 92651 was built in 1964, about six in ten went up before 1970, and more than a quarter date from before 1950. The local water district notes that copper pipes were often used from the 1930s through the 1980s, so many of these lines may have been in service for over fifty years. That is where pinholes and worn joints turn up. The water adds scale along the way: the imported water in the district’s 2025 report averaged 236 parts per million of hardness, about 14 grains per gallon, and that builds up in water heaters and valves.

Three kinds of leak calls we answer in Laguna Beach
Most calls fit one of these. Each one starts with testing, so nothing gets opened on a guess.
Slab Leak Detection & Repair
When a pipe inside the concrete fails, we pin down which one. Then we replace its job with new PEX (flexible plastic water pipe) routed through the attic or walls. The slab itself stays as it is.
- Hot side or cold side confirmed
- Listening done on the pipe itself
- Concrete and tile left in place
Hidden Water Leak Detection
Hidden water leak detection in Laguna Beach covers the leaks you can't see: behind a wall, above a ceiling, or inside a cabinet. We trace the wet spot back to the pipe that caused it and repair it through a small opening.
- Walls, ceilings and cabinets
- Pressure test to prove the leak
- One small access point where possible
Emergency Leak Response
A pipe has let go and water is on the move. We shut it off and contain it first, then work out where it started.
- At your door within 60 minutes
- Main closed and water contained
- Source traced once it's under control
How does a Laguna Beach leak test work, start to finish?
It runs in a fixed order, and no wall, floor or ceiling gets cut until the results line up.
Read the dial
Every faucet and appliance goes off first. If the dial on your meter still turns, you're losing water somewhere. Then the house valve closes. A dial that stops points indoors; one that keeps turning points to the underground run from the curb.
Rule a side in or out
Shutting the water heater's inlet removes the hot lines from the picture. If the loss slows, blame the hot side; if not, look to the cold. Warmth underfoot hints at hot water, though we prove it rather than assume.
Hear it, then prove it
Sensors sit against the pipework (valves, heater fittings, any open length), never against the floor, because a slab muffles sound. A gauge threaded onto a hose spigot then shows pressure falling, a check that stands alone. Thermal imaging plays a supporting role only.
Choose the repair
A failed line in the concrete gets bypassed: new PEX goes up and over through the attic, and the old pipe stays put. A drip at a valve, the heater or inside a wall usually needs only that section replaced. The written plan and price come first.

Verified Google reviews from Cali's Choice leak jobs.
I've recently suffered a slab leak and then an unrelated leak. I used Cali's Choice for the first problem and they were great. Sergio was the lead, and was very upfront, courteous and did very good work…attention to detail. That experience was great so I called Sergio again for our last problem. Our experience was the same - great. I would recommend Sergio and Cali's Choice to anyone.
Sergio and Levi were the plumbers sent out to my house after I suspected having a slab leak. Sure enough they confirmed it. They did an amazing job re-piping my entire house and finished much faster than expected. Very professional and courteous. I will only use them for my future plumbing needs from now on.
I heard a leak in my wall and within 2 hrs they had someone to my house! Sergio was awesome!
Filing an insurance claim for a leak? We'll help you prove it.
A carrier pays on evidence. We gather it while we work and talk to your adjuster directly, so you aren't left explaining plumbing.
- A written cause of loss naming the failed pipe, its material and how it broke.
- Dated, labeled photos of the tests and any opening we make.
- An itemized repair scope, with the reason when rerouting beats a spot fix.
- Calls and follow-up with your adjuster whenever they need more.
- Wet flooring or drywall is a separate restoration scope from our plumbing work. We record it for your claim.
What does slab leak repair in Laguna Beach cost?
No web page can price your job, because the number depends on what the tests turn up. These are the things that move it, so your written quote reads clearly.
What sets the price
How many lines have failed
The simplest job is rerouting one line. When several are going, a bigger reroute or a full repipe can be the better value.
How old the pipe is
In a house from the 1950s or 1960s, one pinhole can mean the rest of that run is thin too. We'll tell you if that changes our advice.
How we reach the pipe
An open attic keeps things quick. A cramped attic or a second story adds labor.
Water damage
Soaked floors or walls are dried and restored as a separate scope, not on our bill. We document it for your insurer.
Our Top of the World house sits high in the hills. Can a technician still reach us within 60 minutes?
Yes. Top of the World sits near Temple Hill, the city’s high point at 1,007 feet, and it is inside our 60-minute window like every Laguna Beach street. Call any time, day or night. The technician tests for the leak first and puts the repair price in writing before anything is opened.
Bluebird Canyon had a landslide in 1978. Can moving ground crack a water line?
Shifting ground can strain buried pipe. That 1978 slide, in the western part of the canyon, destroyed 24 homes. We can’t tell from a phone call whether your ground has moved, but we can tell you if a line is leaking and where. A meter check and listening on the pipe come before anything is opened.
Our South Laguna home gets water from South Coast Water District. Does that change anything?
Not for finding the leak. A small part of South Laguna is served by South Coast Water District, while most of the city is on Laguna Beach County Water District. Either way, the meter at your property shows whether water is escaping, and the testing from there is the same. A rising bill is often the first clue.
Our Arch Beach cottage was built before 1940. What should we expect?
About one in six Laguna Beach homes dates from 1939 or earlier. After that long, a house may have original pipe in one area and newer pipe in another from past repairs. We test before guessing, find the section that is failing, and quote the repair in writing. Detection is free when we do the fix.
We're buying a 1960s house in Laguna Beach. How can we check for a hidden leak?
More Laguna Beach homes standing today date from the 1960s than from any other decade. With every faucet off, look at the meter: a moving dial means water is leaving. Also watch for warm spots on the floor, the sound of running water or a bill that keeps climbing. If anything looks off, call and we’ll test it.
Warm floor or a Laguna Beach water bill that won't settle? A technician can be there in 60 minutes.
A local technician finds the leak first and gives you a written quote before anything is opened. If it isn't our kind of job, we'll say so.
