Thermal Imaging for Slab Leaks in Los Angeles, CA
Thermal imaging cameras allow us to see temperature differences on surfaces, which can indicate a hidden water leak. As water escapes a hot water line, it creates a clear thermal signature on the concrete slab. This technique is particularly useful for hot water line leaks and helps us narrow down the search area significantly without any physical disruption to your property in Los Angeles.

Post-Tension Slab Leak Detection in Los Angeles
Many newer homes are built on post-tension slabs that use steel cables under high tension. Cutting into one without care is dangerous and can damage the foundation. We locate the cables with scanning equipment before any repair access is opened. This lets us repair the leak without risk or recommend a reroute that avoids the slab entirely.
Hot Water Slab Leak Detection in Los Angeles
Hot water lines leak under slabs more often than cold lines because heat speeds up corrosion and causes expansion and contraction. Signs include warm spots on the floor, a water heater that runs constantly and higher gas or electric bills. Thermal imaging shows the heat pattern spreading through tile or concrete. We confirm with a pressure test and acoustic listening before flagging the spot.
Slab Leak Repair Through Direct Access in Los Angeles, CA
When a single leak is found on otherwise healthy pipe, direct access can be the most affordable repair. We cut a small opening in the floor at the marked spot, repair the pipe and pressure test it. Then we patch the concrete and leave the area ready for flooring. Accurate detection keeps that opening as small as it can be.
Video Pipe Inspection for Sewer Leaks in Los Angeles, CA
Sewer line issues under a slab can also look like slab leak symptoms. We use high-resolution video cameras to inspect the interior of your drain lines, identifying cracks, blockages or separations. This is important if the issue isn't a pressurized water line, helping us determine if a sewer line repair is needed instead for your Los Angeles home.
Pressure Testing & Isolation in Los Angeles
When a leak is suspected, we can perform pressure tests on individual water lines. By isolating sections of your plumbing system and monitoring pressure gauges, we can confirm the presence of a leak and often determine which specific line is compromised. This step-by-step approach is crucial for homes with complex plumbing layouts, giving you an accurate diagnosis before any excavation in Los Angeles, CA.
Slab Leak Reroutes in Los Angeles
Rerouting abandons the leaking line under the slab and runs new pipe through the walls or attic. It avoids breaking concrete and often costs less than direct access under finished floors. We typically use PEX for reroutes because it handles heat and resists hard-water corrosion. This option is popular when the slab is covered in tile or hardwood.

Repiping After Multiple Slab Leaks in Los Angeles, CA
If your home has had two or more slab leaks, the remaining pipe is likely corroded too. Repiping replaces all supply lines with new PEX or copper run through the walls and attic. It is a bigger project, but it ends the cycle of repeat slab leaks. We can typically complete a full repipe in two to four days.

Frequently Asked Questions About Slab Leak Detection in Los Angeles
The cost for professional slab leak detection in Los Angeles, CA usually ranges from $250 to $700, depending on the complexity of the leak and the time required for diagnosis. This initial detection fee is separate from any repair costs, which can vary a lot based on the leak's location and required pipe repair.
For significant slab leak repairs, especially those involving excavation or extensive re-piping, a plumbing permit from the local building department is often required. FKM Plumbing handles all necessary permitting processes so your repair is compliant with local codes and regulations, protecting your investment.
Most slab leak detection services can be completed within 1 to 3 hours, depending on the severity and location of the leak. Our goal is always to be as efficient and non-invasive as possible, providing a quick diagnosis so repair work can begin soon.
Most homes in Southern California sit on concrete slabs, so slab leaks often show up as warm floors, wet carpet, or an unexplained jump in the water bill. Hard water can also corrode copper pipes from the inside. Pipes can wear against concrete or gravel as they expand with hot water, and over time these factors cause pinholes and cracks.
We stand by the accuracy of our slab leak detection services. While detection itself is a diagnostic service, we make sure our findings are accurate. Any subsequent repairs performed by FKM Plumbing come with our standard labor and parts warranties, which will be clearly outlined for you.
A water line slab leak involves pressurized fresh water escaping from supply pipes, often resulting in higher water bills, warm spots or the sound of running water. A sewer line slab leak involves wastewater leaking from drain pipes, which usually causes foul odors, slow drains or visible sewage seepage, and is not usually pressurized.
Yes, FKM Plumbing stands behind our work. We offer a warranty on our slab leak detection services, standing behind the accuracy of our findings. Any subsequent repair work performed by us also comes with a comprehensive warranty on parts and labor, providing you with peace of mind.
Once the slab leak is precisely detected, our technician will provide you with a detailed report and discuss the best repair options. These options may include trenchless repair, re-routing the affected pipe or traditional slab excavation and repair. We will then provide a clear estimate for the repair work.
