Acoustic Slab Leak Detection in Norwalk
Our technicians rely on highly sensitive acoustic listening devices to pinpoint the exact location of a leak under your slab. This method involves listening for the subtle sound of escaping water, even through concrete. It's particularly effective for pressurized water lines, allowing us to find leaks without unnecessary excavation and minimizing disruption to your Norwalk home.

Video Pipe Inspection for Sewer Leaks in Norwalk, 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 Norwalk home.
Post-Tension Slab Leak Detection in Norwalk
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 safely or recommend a reroute that avoids the slab entirely.
Slab Leak Detection and Repair Cost Comparison in Norwalk, CA
Slab leak detection usually costs $150 to $450. Direct access repairs usually run $1,000 to $3,000, including concrete patching but not flooring replacement. Reroutes generally cost $800 to $3,500 depending on distance and access. Full repipes cost more, often $4,000 to $15,000, but end the problem permanently.
Thermal Imaging for Slab Leaks in Norwalk, CA
Thermal imaging cameras allow us to visualize 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 quickly without any physical disruption to your property in Norwalk.
Water and Sewer Line Slab Leaks in Norwalk, CA
Slab leaks can affect both freshwater supply lines and sewer drain pipes. Our detection services are set up to identify both types of leaks, which present different challenges. Sewer line leaks often involve foul odors and slow drainage, while water line leaks can appear as wet spots or high water bills in your Norwalk, CA home. We have specific methods for each.
Emergency Slab Leak Response in Norwalk
A slab leak that is flooding floors or causing water to bubble up through tile needs fast attention. We respond quickly, help you shut off the water and isolate the leaking side if possible. That often lets you keep partial water service until the repair. Then we locate and fix the leak.

Frequently Asked Questions About Slab Leak Detection in Norwalk
The cost for professional slab leak detection in Norwalk, 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.
Common pipe materials prone to slab leaks include older copper pipes susceptible to corrosion from hard water or soil acidity, and sometimes PEX or CPVC if they were improperly installed or exposed to extreme temperatures. Galvanized steel pipes, though less common under slabs today, can also corrode and leak.
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 fast diagnosis so repair work can begin soon.
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.
While the detection process itself usually doesn't require a permit, any subsequent repair work involving the excavation of the slab or significant plumbing alterations will likely require a plumbing permit from the local building department. FKM Plumbing handles all necessary permits for repair work.
Yes. Our slab leak repairs and reroutes carry a written workmanship warranty, and PEX systems from brands like Uponor include long manufacturer warranties. We explain the coverage before you approve the work. That gives you peace of mind on the job.
Yes. Water leaking under the slab can cause expansive soil to swell or wash away supporting soil. Over time this can lead to cracks and sinking. Fixing leaks quickly protects the foundation.
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.
