How We Locate a Slab Leak Before Cutting Anything
Slab leak detection pinpoints the exact location of the leak beneath the concrete before any floor is opened. Corona Plumbing Pros uses two detection methods on every slab leak call: acoustic listening equipment that amplifies the sound of water escaping under pressure, and infrared thermal imaging that identifies temperature differences on the floor surface caused by a warm water leak below. Together these two methods locate the leak to within a few inches — minimizing how much concrete needs to be opened.
Acoustic Listening Equipment
An acoustic sensor placed on the floor surface picks up the sound of water escaping from a pressurized pipe beneath the slab. The technician moves the sensor across the floor until the signal peaks — that is the leak location. This method works through tile, hardwood, carpet, and bare concrete.
Infrared Thermal Imaging
A thermal camera detects temperature differences invisible to the eye. A hot water supply line leaking beneath the slab creates a warm patch on the floor above it that shows clearly on infrared. Combined with acoustic detection, thermal imaging confirms the location before we recommend cutting anything.
How Accurate Is Slab Leak Detection?
Our detection methods locate the leak to within 6 to 12 inches in most cases on a standard Corona residential slab. We open the minimum area of concrete necessary to access the pipe. The smaller the opening, the less concrete repair is needed after the plumbing work is done.

Slab Leak Repair Options in Corona, CA
There are four ways to repair a slab leak in a Corona home. We give you the cost and honest recommendation for each applicable option after detection. You decide.
Spot Repair — Open the Slab and Fix It
We saw cut the concrete directly above the leak, expose the failed section of pipe, repair or replace it, and patch the concrete. This is the right option for a single isolated leak in an otherwise sound pipe. The concrete patch is part of the job.
Best for: isolated failures in accessible locations where the surrounding pipe is in good condition.
Pipe Rerouting — Bypass the Slab
Instead of cutting the slab, we reroute the supply line through the wall, ceiling, or attic — bypassing the failed section beneath the concrete entirely. No slab is cut. The old pipe is abandoned in place and the new line runs above ground through the living structure.
Best for: leaks in difficult-to-access locations, repeated failures in the same buried line, or when the homeowner wants to avoid concrete work entirely.
Epoxy Pipe Lining
A flexible epoxy liner is applied inside the existing copper pipe, sealing pinhole leaks without any excavation. The liner cures inside the existing pipe and creates a smooth new interior surface.
Best for: early-stage pinhole failures in accessible pipe with sound overall pipe structure. Not appropriate for severely corroded pipe or collapsed sections.
Full Repipe to PEX
When detection and pressure testing reveal widespread pinhole failures across multiple sections — common in Eagle Glen and Sierra Del Oro homes approaching 50 years old — a full repipe to PEX is the right answer. We run the new PEX through walls and attic rather than through the slab, which means no future slab penetrations on the new system.
Best for: homes with multiple slab leaks, widespread copper corrosion confirmed by pressure testing, or pre-1990 homes where the full copper system is approaching failure age.

Call (951) 574-8995Types of Slab Leaks We Fix in Corona
Slab leaks in Corona occur in several different locations depending on the home's layout, pipe routing, and age. The most common is a pinhole leak in a copper hot water supply line embedded in or beneath the concrete floor — but slab leaks also occur at the slab perimeter, under driveways, and in water heater supply lines.
Interior Floor — Hot Water Supply Line
The most common slab leak in a Corona home is a pinhole failure in the copper hot water supply line embedded in or beneath the concrete floor. Hard water at 15.8 to 18 GPG corrodes copper pipe from the inside over 30 to 50 years. The first sign is often a water bill that went up $100 or more with no clear reason, followed by a warm spot on the floor, or the sound of running water with everything turned off.
Slab Perimeter and Foundation Edge
Perimeter leaks occur where a supply or drain line crosses from beneath the slab to the exterior, or where the slab meets the footing. Water from a perimeter leak can work its way toward the foundation over time. Acoustic detection locates the exact crossing point before we open anything.
Water Heater Supply Line Under the Slab
The copper lines connecting a water heater to the rest of the home's supply system sometimes run beneath the slab. These lines face the same hard water corrosion as any other buried copper in a pre-1995 Corona home. Detection and rerouting are both available for this scenario.
Under the Concrete Driveway
Slab leaks are not limited to the interior floor. Supply lines running beneath a concrete driveway or exterior slab experience the same corrosion over time and can fail. Cutting a driveway is more disruptive than an interior floor, which is exactly why we confirm the pinpoint location with acoustic detection before saw cutting begins. Concrete restoration is included in the flat-rate price.
Already Confirmed — Need Repair Options
Some callers come to us after another company confirmed the leak but did not repair it. In these cases we skip straight to repair assessment, confirm or refine the location, and give you written repair options in the same visit.
Leak That Has Forced the Main Water Shutoff
When a slab leak is bad enough that the main water supply has been closed, the home has no water at all. This is a priority call. We respond same-day including Sundays and assess whether a spot repair or immediate reroute can restore water service the same day.
Why Slab Leaks Are Common in Corona
Slab leaks in Corona are predictable for homes built between 1970 and 1995. Three factors drive the problem: hard water at 15.8 to 18 GPG that corrodes copper pipe from the inside over decades, slab-on-grade construction that embeds those copper pipes in or beneath the concrete, and ground movement near the Elsinore fault that adds mechanical stress to buried pipe joints over time.
Hard Water Corrosion — 15.8 to 18 GPG
Calcium and magnesium from Corona's water supply deposit on the inside of copper pipes with every gallon that flows through. Over 30 to 50 years, those deposits combine with the slightly acidic nature of heated water to corrode the pipe wall from the inside out. Pinhole failures develop — too small to see, too pressurized to stop on their own.
Slab Construction and Buried Copper
Most Corona homes built before 1995 are slab-on-grade with copper supply lines embedded in or beneath the concrete. When those pipes fail, water has nowhere to go except up through the slab, under flooring, or out through the perimeter. There is no crawl space to absorb the damage.
Ground Movement Near the Elsinore Fault
The Elsinore fault runs through western Riverside County near Corona. Minor seismic activity — along with clay soil expanding and contracting seasonally — shifts buried pipe joints over years. A connection that was tight when the home was built in 1982 may have moved enough by now to allow a hairline crack at the fitting.
Which Neighborhoods Are at Highest Risk
Sierra Del Oro (92882) and Eagle Glen (92883) have the highest concentration of at-risk copper plumbing — original supply systems in homes built from the late 1970s to early 1990s, now 35 to 50 years old under Corona's hard water. North Corona, California Meadows (92881), and Temescal Valley (92883) follow closely behind.
Pre-1995 home in Eagle Glen or Sierra Del Oro? Your copper is at pinhole failure age. A water bill spike is the first warning sign.

Slab Leak Questions Corona Homeowners Ask
How much does slab leak repair cost in Corona, CA?
Detection runs $300 to $500 using acoustic and infrared methods. Spot repair through the slab costs $800 to $2,500 with concrete patch included. Pipe rerouting runs $1,500 to $4,000. A full repipe starts at $5,000. We give you written pricing for each applicable repair option after detection and before any work begins.
How do you find a slab leak without tearing up the floor?
We use two methods: acoustic listening equipment that amplifies the sound of water escaping under pressure beneath the slab, and infrared thermal imaging that detects temperature differences on the floor surface caused by a warm water leak below. Together these locate the leak to within 6 to 12 inches before we open any concrete.
What are the signs of a slab leak in a Corona home?
The most common signs are a water bill that went up $100 or more with no clear cause, a warm or hot spot on the floor, the sound of running water when everything is turned off, new cracks in tile or hardwood, and damp or soft carpet near exterior walls. Corona homes built before 1995 on slab foundations are at the highest risk.
Can you repair a slab leak without cutting the concrete?
Yes. Pipe rerouting runs the new supply line through the wall, ceiling, or attic instead of through the slab — no concrete is cut. Epoxy lining seals pinhole leaks inside the existing pipe without any excavation. Which option applies depends on the location and condition of the pipe, which we assess after detection.
How accurate is slab leak detection — how close do you get?
Our acoustic and infrared detection locates the leak to within 6 to 12 inches in most cases on a standard Corona residential slab. We mark the floor before recommending a cut. The smaller and more accurate the opening, the less concrete restoration is needed after the plumbing repair.
Do you detect and repair in the same visit?
Yes. We detect the leak, give you a written flat-rate repair quote on the spot, and begin the repair after your approval — all in one visit. You do not need to schedule a second appointment with a different crew. One company, one visit, one invoice.
Should I repair the leak or repipe after a slab leak?
A single isolated pinhole in otherwise sound pipe is a spot repair or reroute. Pressure testing that reveals multiple weak points, or a home with a history of repeated slab leaks, is a repipe candidate. We show you the test results and explain both options with honest pricing before you decide.
Does homeowner's insurance cover slab leak repair in Corona?
Sudden and accidental damage is typically covered. Most slab leaks qualify because the homeowner could not detect the failure without professional equipment. We provide a written detection report with cause, location, and pipe condition documentation after every job — the report your adjuster needs for the claim.
What causes slab leaks in older Corona homes?
Three factors: hard water at 15.8 to 18 GPG that corrodes copper supply lines from the inside over 30 to 50 years, slab-on-grade construction that buries those copper pipes in or beneath the concrete, and minor ground movement near the Elsinore fault that stresses buried pipe joints over time. Homes built before 1995 in Eagle Glen, Sierra Del Oro, and North Corona are at the highest risk.
Can you fix a slab leak under a concrete driveway?
Yes. We have repaired slab leaks beneath concrete driveways in Corona using the same acoustic and infrared detection used for interior slabs. We confirm the exact location before saw cutting begins to minimize the area that needs to be opened and restored. Concrete restoration is included in the flat-rate price.
