Hidden water leaks beneath concrete foundation slabs cause catastrophic structural damage. Our plumbing leak detection services combine acoustic ground listening and FLIR thermal imaging to locate sub-slab leaks within a 1-inch radius before our licensed slab leak plumbers execute clean overhead PEX pipe reroutes. Serving homeowners and businesses across Pomona (Zip codes: 91766, 91767, 91768).
Common symptoms reported by homeowners across Pomona:
A sudden increase in your monthly DWP or water utility bill while household water usage has not changed.
Noticeably warm patches on tile, hardwood, or laminate floors caused by hot water leaking directly beneath the concrete slab.
Hearing rushing water inside walls or under floors even when every faucet and appliance is completely shut off.
The low-flow indicator triangle on your water meter continues spinning when all plumbing fixtures are turned off.
Discolored grout, warped floorboards, or musty mildew smells near baseboards and hallway floors.
Clear, code-compliant execution from licensed California plumbers:
We isolate hot and cold supply lines to confirm exactly which plumbing zone is losing pressure.
We listen to sub-slab sound frequencies and scan floor heat differentials to pinpoint the exact location.
We deliver a detailed diagnosis report and execute the cleanest permanent plumbing repair solution.
Answers to common questions from Pomona property owners:
Our mobile service trucks are staged across the the San Gabriel Valley, providing average response times of 30–40 mins to homes and businesses in Pomona.
Most standard California homeowner insurance policies cover the cost of leak detection and resulting water damage tear-out/restoration, though the physical pipe repair itself is typically homeowner responsibility. We provide detailed diagnostic documentation for your insurance adjuster.
Many Los Angeles homes built from the 1950s through 1990s have copper pipes buried in concrete. Over decades, acidic soil chemistry, hard water friction, and thermal expansion cause microscopic pinhole leaks in copper plumbing walls.
Yes! That is the core advantage of our non-invasive equipment. Acoustic listening discs and FLIR infrared thermal cameras allow our slab leak plumbers to map the leak without touching your floors.
In nearly all cases, an overhead PEX reroute through the attic is superior. It leaves your expensive flooring intact and ensures the failing copper line is retired permanently.
