Slab Leak Repair and Detection in San Diego

Are you noticing unexplained water pooling, a sudden spike in your water bill, or the sound of running water with no fixtures on? Is part of your floor unusually warm? These could all be signs of a slab leak—one of the most serious plumbing issues a homeowner can face. At California Plumbing, we provide expert slab leak repair across San Diego County, serving homeowners in San Diego, Oceanside, Chula Vista, and surrounding communities. When there are signs of a slab leak, our plumbers will bring in a leak detection specialist to identify the source of the issue and offer targeted, long-term repair solutions.

What Is a Slab Leak? (And Why It Matters)

A slab leak occurs when a water line running underneath your concrete foundation cracks, breaks, or corrodes. Because it’s buried beneath your home, a slab leak often goes unnoticed until it causes water damage, mold growth, or a noticeable change in flooring temperature. Early detection is crucial to locate the issue quickly and accurately before the damage spreads.

Getting Started with Slab Leak Detection and Long-Term Repair

Contact California Plumbing today to get started: We can walk you through the process from start to finish. A leak detection specialist can pinpoint the problem using thermal imaging, acoustic listening devices, and other advanced tools. Once the leak is marked and diagnosed, our repair team steps in to deliver precise and effective repairs tailored to your property’s layout and plumbing system.

Slab Leak Repair Options: Rerouting & Repipe Solutions

Unlike sewer lines, water lines under slabs cannot be repaired using trenchless technology. Instead, we typically recommend one of two proven methods: a repipe or a reroute. In many cases, rerouting is the most efficient and least invasive option. By abandoning the damaged line under the slab and rerouting new piping through the walls and ceiling, we eliminate the need for jackhammering through your floors. This not only reduces disruption but also makes future access and repairs easier and more cost-effective.

Frequently Asked Questions

A slab leak occurs when a water line running beneath the concrete foundation of a home develops a leak. In San Diego, older homes in neighborhoods like Clairemont, La Mesa, and Chula Vista often have aging copper pipes that corrode over time. Combine that with seismic activity, shifting soil, and the use of hard water, and slab leaks become a frequent and costly issue. At California Plumbing, we specialize in slab leak detection and repair tailored to the unique soil and foundation conditions of San Diego County homes.

Common signs of a slab leak include unexplained spikes in your water bill, warm spots on the floor, low water pressure, and the sound of running water when no fixtures are in use. In areas like Oceanside and San Diego proper, many homes with radiant heating or older plumbing systems are especially vulnerable. If you suspect a slab leak, contat California Plumbing. We can get you setup for a non-invasive slab leak detection using advanced acoustic and infrared tools.

In San Diego, slab leaks are usually caused by corrosion of copper piping, poor construction techniques, high water pressure, or abrasive soil movement under the foundation. The proximity to the coast can accelerate pipe wear due to high chloride content in the water supply. At California Plumbing, we will put together a plan to identify not just the leak but its root cause—ensuring the problem doesn’t return.

No. When you call California Plumbing we bring in slab leak experts who use advanced, non-invasive slab leak detection equipment to locate the source of the leak with pinpoint accuracy. Using electronic listening devices, thermal imaging, and pressure testing, we can often identify a slab leak without tearing up flooring or concrete. This precision saves San Diego homeowners both time and money.

Slab leak repair in San Diego can range from $1000 for basic spot repairs to well beyond $5,000+ or more for major rerouting or repiping. Factors affecting the cost include the location of the leak, accessibility, and the extent of damage. California Plumbing offers transparent, upfront pricing for all slab leak detection and repair work across San Diego County, including Chula Vista, Oceanside, and surrounding areas.

Jackhammer repair involves breaking through your concrete slab to access and repair the leaking pipe. Rerouting, on the other hand, bypasses the damaged line entirely by installing new piping through walls or ceilings. In many San Diego homes, especially those with finished flooring or tile, rerouting is less invasive and more cost-effective. California Plumbing will evaluate your plumbing system to recommend the best approach for your situation. Supply lines can be rerouted but drains rely on gravity, so the solution offered will depend upon what type of leak you have!

It depends. In many cases, homeowners insurance may cover the cost of accessing and repairing the leak, but not the plumbing repair itself. Coverage varies depending on your policy and the cause of the leak. California Plumbing works with several San Diego-area insurance providers as well as national companies like Geico, Allstate, Farmers, etc. Our team can help document your slab leak for claims support.

Yes. A persistent slab leak can erode the soil beneath your home, leading to uneven settling, cracks in the foundation, and even structural damage. This is especially true in San Diego’s coastal regions where sandy or expansive soil is common. Quick detection and repair from California Plumbing can prevent thousands of dollars in long-term structural issues.

Depending on the method, most slab leak repairs can be completed within 1–3 days. Spot repairs through jackhammering may be quicker, but full pipe reroutes or repipes might take longer, especially if your home is older or has complex plumbing. California Plumbing prioritizes fast, clean work with minimal disruption to your home or routine.

Delaying slab leak repair can lead to significant water damage, mold growth, higher utility bills, and even foundation problems. In San Diego’s climate, mold and mildew can develop quickly under damp floors. If you notice signs of a leak, it’s important to call California Plumbing immediately for fast slab leak detection and repair services before the damage worsens.

Homes in San Diego built before the 1990s often use copper piping, which is highly susceptible to pinhole leaks due to corrosion and soil movement. More recent homes may use PEX or PVC, which are generally more resistant. At California Plumbing, we assess your existing system and recommend the best materials for long-term peace of mind when performing slab leak repairs or repiping.

Yes, California Plumbing provides trenchless options such as epoxy pipe lining and pipe bursting to repair slab leaks with minimal disruption. These methods are ideal for homeowners in San Diego who want to preserve their flooring, landscaping, or hardscape. Trenchless repair also reduces repair times and restores full water service faster than traditional excavation methods. Please note that trenchless repair cannot be done on supply side pipes (the ones that bring hot and cold water to your fixtures). Trenchless methods are only useful for drain pipes which have extra room for an interior coating. Supply pipes will instead need to be replaced in the slab or re-routed through walls and ceilings if trenching the slab is not an option / not cost effective.
