Electronic Slab Leak Detection in Los Angeles, CA
Hidden water leaks beneath concrete foundation slabs can cause immense structural damage and mold growth. We use high-frequency acoustic sensors and thermal imaging to find leaks with pinpoint precision before cutting into floors.
5 Subtle Signs You Have a Hidden Slab Leak
If you notice any of the following symptoms in your property, call our technicians for a clear evaluation:
Unexplained Water Bill Spikes
A sudden increase in your monthly DWP or water utility bill while household water usage has not changed.
Warm or Hot Spots on Floors
Noticeably warm patches on tile, hardwood, or laminate floors caused by hot water leaking directly beneath the concrete slab.
Sound of Running Water Constantly
Hearing rushing water inside walls or under floors even when every faucet and appliance is completely shut off.
Spinning Water Meter Indicator
The low-flow indicator triangle on your water meter continues spinning when all fixtures are turned off.
Damp Flooring, Buckled Wood, or Mold
Discolored grout, warped floorboards, or musty mildew smells near baseboards and hallway floors.
Direct Slab Jackhammering vs. Overhead PEX Reroute
Understanding your repair choices after locating a slab leak:
Overhead PEX-a Pipe Reroute
- ✓Abandons the failed underground line inside the concrete slab
- ✓Runs a new, continuous Uponor PEX pipe through attic or wall cavities
- ✓Zero destructive jackhammering of your finished tile or hardwood floors
- ✓Eliminates future leak risk on that line permanently
Direct Slab Access & Spot Repair
- ✓Jackhammers through flooring and concrete slab directly above leak
- ✓Solders or replaces a localized copper fitting under the slab
- ✓Requires floor patching and concrete remediation
- ✓Leaves remaining decades-old copper pipe buried in corrosive soil

Frequently Asked Questions About Leak Detection
Clear, direct answers to common questions from Los Angeles homeowners:
Will my homeowner’s insurance cover slab leak detection and repairs?
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.
Why do slab leaks happen so frequently in Southern California?
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 the copper pipe walls.
Can you detect a leak without tearing up my flooring?
Yes! That is the core advantage of our non-invasive equipment. Acoustic listening discs and FLIR infrared thermal cameras allow us to map the leak without touching your floors.
Is it better to repair a slab leak or reroute the pipe overhead?
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.
How long does a slab leak detection take?
A comprehensive residential leak detection typically takes between 1.5 to 3 hours to perform pressure isolation, acoustic scans, and thermal verification.
