Slab Leak Detection & Repair in Murrieta, CA
Call Now (951) 387-4879Slab leaks are one of the most common — and most stressful — plumbing problems in Murrieta right now, and there is a very specific reason why. The 2000-2008 construction boom that built Greer Ranch, Spencer's Crossing, The Oaks, California Oaks, and Bear Creek used copper supply lines routed underneath post-tension concrete slabs. Those copper lines have been exposed to EMWD's extremely hard water at 15-25 grains per gallon for 18-26 years. That hard water corrodes copper from the inside out, gradually thinning the pipe walls until pinhole leaks develop. The result is pressurized water escaping under your foundation 24 hours a day, saturating the soil, wicking up through the concrete, and damaging your flooring, baseboards, and subfloor.
The signs homeowners notice first are often subtle: an unexplained spike in your water bill, the faint sound of running water when every fixture is turned off, a warm or hot spot on the floor (especially on the hot water side), damp carpet or warped laminate flooring, or small cracks appearing in walls near the foundation. If you are noticing any of these in your Murrieta home, call us at (951) 387-4879 immediately. Slab leak damage compounds every day the leak runs — what starts as a damp spot can become a mold problem, a flooring replacement, or foundation damage if left unaddressed.
There is a critical detail about most Murrieta homes that affects how we repair slab leaks: post-tension slabs. The majority of homes built during the 2000s boom in Murrieta used post-tension concrete foundations, which contain high-tension steel cables running through the slab. You cannot safely jackhammer into a post-tension slab to access a leaking pipe — cutting one of those cables can cause catastrophic structural failure. This means the standard direct-access repair (cutting through the slab to reach the pipe) is not an option for most Murrieta homes. Instead, the safe and permanent repair is a line reroute — we abandon the leaking under-slab pipe and run a new supply line through the walls or attic to bypass the slab entirely. If you have had multiple slab leaks or the under-slab copper is showing widespread corrosion, a full water line reroute through the attic eliminates the problem permanently by taking all supply lines out of the slab.
We detect slab leaks using electronic amplification equipment and thermal imaging cameras that pinpoint the leak location through the concrete without any demolition. In most cases, we can identify the leak within a few feet and determine whether it is on the hot or cold supply line before we discuss repair options. If your slab leak is actively flooding, call our 24/7 emergency line immediately.

Our Slab Leak Detection & Repair Process
Non-Invasive Leak Detection
We use electronic amplification equipment and thermal imaging cameras to locate the leak through the slab without tearing up your floor. We listen for the sound of pressurized water escaping the pipe and use thermal imaging to identify hot spots that indicate a hot-side leak. In most cases, we can pinpoint the leak within a few feet.
Pressure Isolation Test
We isolate the hot and cold supply lines and perform separate pressure tests on each to confirm which line is leaking and verify the leak location. This step confirms our detection findings and tells us whether we are dealing with a single leak or multiple failure points — which affects the repair recommendation.
Repair Options and Upfront Pricing
We explain your repair options with firm pricing for each. For most Murrieta homes on post-tension slabs, the only safe option is a line reroute through the walls or attic. For homes on conventional slabs, direct access repair may also be an option. If we detect multiple leaks or widespread pipe corrosion, we discuss a full water line reroute that permanently eliminates the problem.
Complete the Repair and Pressure Test
We perform the repair — running new supply lines through walls and attic space to bypass the leaking under-slab section, or accessing the leak directly on conventional slabs. After the repair, we perform a final pressure test on the entire system to verify the fix holds under full water pressure. We confirm there are no secondary leaks.
Cleanup and Insurance Documentation
We clean up the work area and restore access panels. We provide complete documentation with photographs of the detection process, leak location, damage, and completed repair for your insurance claim. Most homeowners insurance policies cover the resulting water damage (flooring, drywall, mold remediation) even though the plumbing repair itself is typically out of pocket.
Frequently Asked Questions
The most common signs are: an unexplained increase in your water bill (even $20-$30 more than usual can indicate a leak), the sound of running water when all fixtures are turned off (put your ear to the floor in a quiet room), warm or hot spots on the floor (indicating a hot-side leak), damp or discolored carpet, warped laminate or hardwood flooring, small cracks in walls near the foundation, or a musty mold smell in areas near the slab. If you notice any of these, call us immediately — slab leak damage gets worse every day the leak runs, and what starts as a minor moisture issue can become major flooring damage, mold growth, or foundation problems.
