Slab Leak Detection in Mission Viejo
We start by shutting off fixtures and watching the meter to confirm a leak. Then we isolate the hot and cold lines to find out which one is leaking. Using acoustic ground microphones, we listen for the sound of escaping water through the concrete. Thermal imaging shows hot water leaks as warm areas on the floor surface.

Hot Water Slab Leak Repair in Mission Viejo, CA
Hot water lines leak under slabs more often than cold lines because heat expands and contracts the pipe against concrete and gravel. Mineral scale and constant recirculation can wear the pipe wall faster. We repair the leak or reroute the hot line, and we can adjust recirculation pumps to reduce wear. Warm floors and higher gas or electric bills are common signs.
Slab Leak Repair Cost Comparison in Mission Viejo, CA
Spot repairs usually have a lower upfront cost but involve breaking concrete and repairing flooring. Reroutes cost a bit more but avoid concrete work and future leaks in that line. Whole-house repipes are the best choice when you have had multiple slab leaks or old copper throughout. We give you written prices for each option.
Electronic Slab Leak Detection in Mission Viejo
Locating a hidden slab leak requires specialized tools. Our plumbers use advanced electronic listening devices and thermal imaging cameras to pinpoint the exact location of the leak under your concrete foundation. This precise detection minimizes the need for extensive concrete removal, saving you time and money. We can detect leaks in both hot and cold water lines, as well as sewer lines, for a thorough diagnosis of your Mission Viejo home.
Slab Leak Reroute in Mission Viejo
Rerouting is often the best long-term choice, especially with older copper lines. We abandon the leaking line under the slab and run a new PEX line through the attic and walls. Openings are small and placed where patching is easiest. Reroutes end future leaks in that section of pipe.
Direct Slab Leak Repair in Mission Viejo, CA
When a slab leak is localized and accessible, direct repair is often the most practical solution. This involves carefully jackhammering a small section of your foundation to expose the damaged pipe, then repairing or replacing the damaged section. Our technicians are skilled in precise concrete cutting and restoration, so the repair is effective and the area is professionally restored. We use durable materials designed to hold up to soil movement under the slab.
Tunneling Slab Leak Repair in Mission Viejo, CA
In some cases, especially when the leak is under a load-bearing wall or in a hard-to-reach area, tunneling beneath the foundation is the preferred method. This lets our plumbers reach the damaged pipe from outside your home, avoiding disruption to your interior floors and finishes. Tunneling spares the interior but requires skilled excavation and shoring to protect structural integrity throughout the repair process in Mission Viejo, CA.

Spot Repair Through the Slab in Mission Viejo, CA
When the leak is isolated and the rest of the pipe is in good shape, a spot repair through the slab is a practical option. We cut a small opening, excavate to the pipe and replace the damaged section. The trench is compacted and the concrete is patched. Flooring is then restored by your preferred contractor.

Postwar tract homes are common in Southern California, and many still have original galvanized or copper supply lines and cast iron drains under the slab. When water lines run under the concrete, water chemistry, heat and shifting soil can make slab leaks one of the more common plumbing repairs in Mission Viejo, CA.

Frequently Asked Questions About Slab Leak Repair in Mission Viejo
The cost of slab leak repair in Mission Viejo, CA can vary widely, typically ranging from $1,000 to $5,000 or more, depending on the leak's location, severity, and chosen repair method. Simple direct access repairs might be on the lower end, while extensive rerouting or tunneling will be higher. We provide a clear, upfront estimate after a thorough inspection.
Depending on the extent of the repair, especially if it involves major structural work, pipe rerouting, or changes to the main water line, a plumbing permit may be required by local authorities. FKM Plumbing will handle all necessary permit applications so your slab leak repair is fully compliant with local building codes.
Slab leaks can be caused by several factors, including shifting soil that puts stress on pipes, corrosive water chemistry leading to pinhole leaks in copper, poor pipe installation, and general aging of plumbing materials. 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. Around Mission Viejo, flushing the water heater yearly and cleaning aerators keeps mineral buildup from cutting flow and efficiency.
A simple direct slab leak repair can often be completed in a single day. More complex repairs involving pipe rerouting or extensive repiping might take 2 to 5 days, depending on the scope of work and the size of your Mission Viejo property. We always aim for efficient service with minimal disruption.
Warm spots on the floor, damp carpet, cracks in tile, mildew odors, the sound of running water and a water meter that moves with fixtures off are common signs. A sudden jump in your water bill is also a clue.
Detection usually takes one to three hours. Spot repairs and reroutes usually take one to two days.
Yes. Water seeping into flooring, carpet padding and wall bottoms can lead to mold growth. Repairing the leak promptly and drying the area helps prevent it.
Many homeowner policies cover access to the leak and resulting water damage but not the pipe itself. We provide detailed reports to help with your claim.
