Newport Beach Slab Leak Detection & Repair
One patch of floor warmer than the rest. A water bill that stepped up and stayed there. A meter turning with every faucet closed. Newport Beach slab leak repair starts by naming the buried run and the side it belongs to. On copper poured in the seventies, replacing that run overhead beats cutting concrete to close a single hole.

Said plainly at the start: slab and water lines are the work. Pool and spa leaks, irrigation, and natural-gas lines sit outside it. Anything inside the slab, beneath the foundation, or in a wall feeding a fixture is ours.
Three eras of foundation, and only one of them behaves like a slab leak.
Before anything else we settle what is under your floor, because in this city that genuinely varies. Census figures put 7.8 percent of the housing before 1950, most of it on the peninsula and the island, from a period before slab-on-grade was the normal way to build here. Where a house sits over a crawl space the pipe can be reached directly, and that is a different and generally cheaper afternoon than a bypass.
The middle era is the one that produces most of this work. Around the harbor the Census ZIP medians run from 1954 on Balboa Island to 1973 in West Newport, which puts that copper fifty years and more cast into concrete, with no maintenance window and no way to inspect it. A run buried that long has aged identically along its whole length, so when one section gives way the sections either side are the same age and the same wall thickness.
Then there is Newport Coast, where the Census median is 1998. Foundations of that era are more often post-tension, which carry tensioned steel cable through the concrete and must never be cut into. That happens to suit how we already work, because we do not cut conventional slabs either. Whichever of the three you have, the failed line gets capped and its replacement runs overhead.
No Callout Charge
The service call costs nothing. No trip charge and no add-on before anyone has looked at the house.
Always On Call
Nights, weekends, holidays, a slab leak does not wait. We isolate the line, cap the water, and stop the damage now.
Written Estimates
Reroute scope in writing, with the diagnostic behind it. The price lands before any drywall opens.
Slab work across two very different housing ages
Census ZIP medians from the 1950s to the 1970s on the harbor side and 1998 up on the coast means two sets of buried pipe inside one city. The older runs fail from age, the newer ones at fittings and connections. These six jobs cover both, and the diagnosis decides which applies.
Naming The Buried Run
Our locate answers one question: which line under the floor has failed, and on which side of the system. We work listening equipment along the pipe and confirm the loss with a gauge. We open nothing to reach that answer.
- Hot and cold separated at the heater
- Escape followed along the metal
- Gauge reading recorded as evidence
Overhead PEX Replacement
Our usual answer where the copper is fifty years old. We cap the buried run and abandon it where it lies, then take a PEX-A line over through the wall and the attic, leaving your flooring exactly as it was.
- Old run capped at both ends
- PEX-A carried above the ceiling
- Pressure tested and warranted
Fittings On Newer Builds
On later construction we frequently find the pipe sound and the connection not. A failed fitting under a floor still forces the same decision, but a system with decades left in it changes what we recommend around that decision.
- Failure point identified before pricing
- Remaining service life assessed honestly
- Replacement scoped to what has actually gone
Repairs You Can Reach
A valve under a cabinet, a connector at the heater, a line inside a wall: not every suspected slab leak is buried. We repair those on the visit that found them, with no concrete involved at any point.
- Spent section cut out and renewed
- Copper or PEX, the owner's choice
- Tested before the opening is closed
Whole-House Repipe
Where more than one run has gone on older copper, we put the system into PEX and end the sequence rather than interrupt it. We work overhead in stages and do not touch the slab at any point.
- Both sides renewed in PEX-A
- Two to four days, phased
- Pressure regulator verified afterward
Insurance Evidence
Slab claims are read closely and refused on paperwork as often as on facts. We prepare the cause of loss, the dated photographs and an itemized scope, and send them to the adjuster with the reasoning behind the repair we chose.
- Cause of loss recorded at the visit
- Photographs indexed and captioned
- Carrier billed direct where the policy allows
Finding it without touching the concrete.
We reach the answer with the concrete untouched. Six moves, beginning at the meter and ending on a specific conclusion: which line, which side, and whether a bypass is needed at all. None of it requires opening the floor.
We settle all of that while the floor is still intact, which is the reason these jobs finish with a patch of drywall rather than a rebuilt room. The jackhammer and the educated guess belong to somebody else's method.
Start at the meter
House closed down, every outlet off, and the meter watched. A dial that holds still means nothing is escaping. A dial that creeps means something is, and at this stage that is the only thing worth establishing.
Narrow it to the building
Closing the main separates the house from the service line. A dial that stops puts the loss inside, concrete included. One that carries on puts it out toward the street, which is a different job and not a slab leak.
Split the system at the heater
Shutting the cold inlet halves it. A signal that drops away implicates the hot run, one that persists implicates the cold. A warm spot underfoot is suggestive only, so what the listening gear says is what counts.
Listen on the metal, never the floor
Valves, the heater, any run within reach. Concrete swallows the sound and shifts where it appears to originate, so listening through it misleads. We are not marking a spot to break open. We are identifying a line to retire.
Confirm with a gauge
Gauge onto a hose bib, main shut, needle watched. A steady drop is independent proof that water is escaping right now, and the rate of the drop indicates roughly how much.
Thermal where it earns a place
A hot-side failure under a hard floor occasionally reads clearly on a thermal scan. It corroborates the acoustic finding rather than replacing it, and most jobs are settled without it.
The floor is the obstacle, not the repair.
Where the failure lies under concrete, the line is bypassed rather than dug out. Two things decide that, and both are laid out before anyone commits to a scope.
One is the condition of what is buried. Copper poured in the mid-seventies has half a century of service in it and wears evenly, so if we seal the point that gave way we leave the rest untouched and no younger. The other is the collateral cost: breaking into a floor means saws, dust, and vibration carried straight along the pipe we are trying to save.
A replacement run above the slab
We climb new PEX up the wall, across the attic and back down at the fixture. We seal the old line and leave it where it is. We take no concrete out and match no finishes afterward.
Cutting in to seal one point
Opening the floor repairs the spot that surfaced and leaves every other foot of the same run in service. The following failure usually appears on that line, and the work of reaching the first can be what starts it.
Taking the buried line out of service
For any pipe failure under the concrete, hot or coldWe stop the leak by retiring the failed run and carrying its replacement above the floor. Our reasoning is practical rather than presentational:
-
The remaining length stops being a liability We replace the run and settle the whole line, rather than the one point that announced itself.
-
We put nothing percussive near tired copper Cutting equipment transmits shock through the slab and into the pipe, which can open a second failure while we are closing the first.
-
Your finishes stay as they are That matters more here than in most places, because a good deal of the flooring in this city is stone, hardwood or tile we could not match from stock.
-
We warrant the new work PEX comes with long-term coverage on parts and labor, which we could not honestly give a patch into fifty-year-old copper.
-
Nobody can cut a post-tension slab at all The cables inside them are under load. Working above the floor sidesteps the question entirely, whichever foundation you have.
When a straightforward repair is the right call
When the leak is NOT in the slabNot every leak a homeowner calls a slab leak is one. Where the failure sits above the floor we do an ordinary repair, and our diagnostic usually establishes that quickly.
-
At a valve in the open Under a sink, behind a toilet, at the laundry connection. Old part off, new part on, done on the visit.
-
At the heater A flexible connector, a union, the inlet fitting. Visible, reachable, and we repair it without opening a thing.
-
Inside a wall cavity A pinhole on a fixture feed, well above the floor. We make a small opening, replace the section and patch the drywall.
-
Through concrete, not at any price Where our diagnostic places the failure under the slab, we bypass the line. That does not change with the quote.
Anyone offering to open a floor in order to patch one hole in copper this old is worth a second opinion before you agree to it. The arithmetic seldom favors it and the rest of the run stays exactly as it was.

What homeowners say about our slab work.
Verified Google reviews from slab leak jobs handled by the team that serves Newport Beach.
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.
A water leak under our slab was carefully fixed by Sergio and Levi. They worked for 11 hours straight so that we could have running water that evening .Estimates were reasonable, repairs were explained, areas were cleaned upon job completion…what more can one ask for? A+ all the way!
Their service is awesome! were quick and very honest people Their services professional, and super helpful.
We build the claim file. You do not touch it.
None of the claim is yours to do. We assemble it, submit it and defend it where it is queried: the event in the insurer's language, the costs broken out, and pictures of the metal that gave way.
It matters because of everything a household policy deals with, a buried failure with water damage is read the most closely. Anything absent and the claim simply stops moving.
- How the loss occurred, in writing. Which side of the system failed, the era of the build, the material, phrased for the adjuster.
- The photographic record. The readings, the opening, the spent copper, everything the water reached, dated and ordered.
- Costs broken out, bypass against reachable repair, each element with the reason it was necessary.
- The adjuster hears from us, not from you. Pushback is answered here and further evidence goes over from here.
- The argument for going overhead rather than through the floor, with the investigation attached to it.
What slab leak repair costs in Newport Beach.
Any figure we quoted before seeing the house would be a guess. The spread here is wider than most cities, because a single-story harbor-side house from the seventies and a two-story build from the late nineties are different jobs with different access. Below is every factor that moves the number, so the written quote reads as arithmetic.
What sets the number
How old the buried run is
Copper from the mid-seventies that has failed once is generally worn along its length, which often turns a single reroute into a whole-house conversation. Later pipe with a failed fitting usually does not.
One line or several
A single run we replace from the heater to one part of the house is the common job. Two runs, or a full repipe, scale up from there in both labor and materials.
Route and roof space
Our labor tracks how far we have to take the new line and what the space above it is like to work in. A shallow attic, a flat roof or a second story all add time to the same repair.
What has to be opened and restored
Two drywall openings covers most jobs. Awkward routes want a third. We quote the patching and texture matching with the work, and where a finish is unusual we price it before we start, not after.
Damage that was already there
Anything soaked before we arrived belongs to a separate scope and a different trade. We document it for the claim and keep it off the plumbing invoice.
Is there a slab under this house at all?
Usually, though not always. The Census puts 7.8 percent of the city’s homes before 1950, and many of those sit over a crawl space rather than poured concrete. We confirm the foundation at the start, because it changes the diagnosis and the repair alike.
Ours is a mid-seventies house near the harbor. Does that make a leak likely?
It puts the house in the group these calls come from. On the harbor side, where Census ZIP medians run from the 1950s to the 1970s, buried copper has now run for fifty years and more, and it fails from the inside without warning. Age is a reason to check, not a diagnosis.
We are up on Newport Coast. Is our situation different?
Materially, yes. At a median build year of 1998 we generally find the pipe itself sound and the failures starting at fittings and connections instead. Our repair decision is the same when it is buried, but what the rest of the system needs is not.
What am I actually looking for?
A warm area of floor, a water bill that rose and stayed up, running water you can hear with everything shut, hot water pressure that has fallen away, or a meter still turning after you close the main. One is worth a call. Two together is usually a buried line.
How quickly can somebody get out?
Within the hour where water is actively causing damage. For a suspected leak doing nothing visible, same day or next. We book the locate as its own appointment, because doing it in a hurry gives us the wrong line and you the wrong repair.
Does the repair mean lifting the floor?
Not for a buried failure. We cap the old run where it lies and take a replacement overhead through the wall and attic. That matters here, because the stone and wide-plank floors in these houses are rarely matchable once they come up.
This is the second one. How concerned should I be?
Concerned enough to look at the whole system rather than the one run. At a second failure on fifty-year-old copper, a full repipe usually costs you less across five years than a sequence of individual repairs. We put both figures in front of you and the choice stays yours.
Repair or replacement, which will it be?
Wherever the failure sits makes that decision. We repair a reachable one on the visit. A buried one we bypass overhead, because opening the floor closes a single point and leaves the rest of the line exactly as it was.
The house is on the peninsula with original finishes. How much gets disturbed?
Two drywall openings in most cases, both patched and finished. We plan the route to avoid original material wherever we can, and we discuss and price anything unusual about the finish before we begin. We take nothing original out without agreeing it with you first.
Will the insurance cover it?
Often the damage, sometimes the access, seldom the pipe. The wording of the claim does most of the work, which is why we prepare the cause of loss, the photographs and the itemized scope here and send them to the adjuster ourselves.
How do you find it without opening anything?
We listen at the pipe rather than through the floor. Acoustic equipment follows the escape along the run and a pressure gauge confirms which side has lost integrity. We use thermal imaging to support a hot-side finding, never to lead.
Whose pipe is the one under the floor?
Yours. Whichever water provider serves your address owns the main and the meter at the property line, and everything past that meter is the homeowner’s, including whatever is buried in the slab. That is the side we work on. Their responsibility stops at the meter, and ours starts at the failure.
How long will we be living with this?
Not long. We usually finish the locate on the same visit, often inside a couple of hours. A single overhead reroute is commonly a one-day job. A whole-house repipe takes a few days, phased so you are never without water. The timeline goes in writing alongside the quote.
