Water Leak Detection in Woodland Hills, CA
A water leak you can see is the easy kind. A water leak you cannot see can run for weeks under a slab, behind a wall, or above a ceiling before anyone notices, and by that point the damage usually costs more than the leak repair itself. Bryco Plumbing finds hidden leaks across Woodland Hills, the San Fernando Valley, Los Angeles, and Ventura County using electronic acoustic detection, thermal imaging, and pressure testing. License #708581. 30+ years of pinpointing leaks before the floor has to come up.

Signs You May Have a Hidden Water Leak
Most hidden leaks announce themselves indirectly. The trick is recognizing the pattern early.
- Unexplained higher water bill with no change in your usage habits. A consistent bill increase of 20 percent or more is a red flag.
- Sound of running water when no fixtures are in use. Stand still in the house at night, no appliances running. If you hear a faint hiss or trickle, something is leaking.
- Warm or hot spots on the floor. Most often indicates a slab leak in a hot water supply line under the foundation.
- Damp, musty, or mildew smell from inside walls, cabinets, or in a particular area of the house.
- Visible discoloration, bubbling, or staining on walls or ceilings without an obvious source.
- Soft, warped, or buckled flooring especially over a slab foundation.
- Patches of unusually lush, green grass or wet soil over the path where your water service line runs from the meter to the house.
- Lower water pressure at multiple fixtures simultaneously.
Caught early, most leaks are a small, targeted repair. Left alone they turn into water damage. If you spot any of these signs, call 818-349-9000.

How We Find Leaks That Other Plumbers Cannot
The right tools matter. Three decades of experience using them matters more.
Electronic Acoustic Leak Detection
Specialized equipment that listens for the high-frequency sound of pressurized water escaping a supply line. The technology can pinpoint a leak under a concrete slab to within a few inches, which is the difference between cutting a 12-inch access hole and a 4-foot trench.
Thermal Imaging
Infrared cameras detect temperature differentials. A hot water leak under a slab heats the concrete above it, which shows up clearly on thermal imaging. A cold water leak causes cooling that also shows up. Thermal imaging works through drywall, flooring, and concrete.
Pressure Testing
The diagnostic that proves whether a leak exists in the first place. We isolate sections of the supply system and pressure-test each one. The section that fails to hold pressure has the leak. From there, the acoustic and thermal tools narrow down the exact location.
Video Camera Inspection
For sewer and drain lines, we use sewer video inspection to find leaks, cracks, root intrusion, and partial collapses without excavation.
Common Hidden Leaks We Find in Valley Homes
From slab leaks to pinhole failures, here are the hidden leaks we locate and repair most often across Woodland Hills, the San Fernando Valley, and Ventura County.
Slab Leaks
Slab leaks in copper supply lines under foundation slabs, especially in homes built 1950-1985. The Valley's housing stock has thousands of these.
Pinhole Leaks
Pinhole leaks in copper supply lines behind walls. Often a pattern, not a one-off.
Main Service Line Leaks
Main water service line leaks between the meter and the house, often in the front yard.
Shower Pan Leaks
Leaking shower pan causing damage in the room or unit below.
Failed Toilet Wax Ring
Failed wax ring under a toilet slowly leaking into the subfloor and the ceiling below.
Appliance Water Line Leaks
Failed dishwasher or refrigerator water line leaking under cabinets.
Irrigation Line Leaks
Outdoor irrigation line leaks from broken sprinkler manifold connections or aged drip system fittings.
What Happens After We Find the Leak
Detection is half the job. The repair is the other half, and we do both. Depending on the location and severity of the leak, the repair may involve:
- Spot repair of an isolated leak in an accessible line.
- Section repipe of a problem area (often the smarter call than chasing pinhole leaks one by one).
- Full home repipe in copper or PEX for systems with chronic issues.
- Slab leak repair, either by rerouting the affected line above the slab or by accessing the line through the slab.
- Coordination with restoration services if water damage has occurred.
The Cost of Waiting
A small supply line leak can drop several gallons per day. Multiply that by weeks or months and the water damage compounds. A slab leak that runs unaddressed for six months can require:
- Flooring replacement (laminate, hardwood, or carpet)
- Subfloor remediation if the moisture reached the wood
- Drywall replacement for any wicking up walls
- Mold remediation if the wet area stayed damp long enough
- Repair of cabinets, baseboards, and trim affected by the damage
- The original leak repair itself, which is usually the smallest cost in the whole chain

Frequently Asked Questions About Water Leak Detection
Leak detection cost varies based on the type of leak suspected, the equipment needed, and access. A straightforward acoustic detection visit is much less than the cost of a leak running for another month. We give a written estimate before the visit. In most cases the cost of detection is a small fraction of the repair savings from finding the leak precisely instead of guessing.
Yes, in most cases. The whole point of electronic and thermal leak detection is to locate the leak before anything gets cut open. Once we know exactly where the leak is, the access cut is small and targeted. The alternative (cutting open walls or slab without precise location) costs far more and creates more repair work afterward.
A slab leak is a leak in a water supply line running under the concrete foundation of the home. Most Valley homes built between 1950 and 1985 sit on slab foundations with copper supply lines running through them. Slab leaks are serious because they are out of sight, run continuously, and damage the structure and finishes of the home. They are also relatively common in older Valley housing stock, and they are absolutely fixable.
Sooner is always cheaper. A leak that has been running for a few days is much easier to repair than one that has been running for a few months. If you notice any of the warning signs, especially an unexplained water bill increase or a warm spot on the floor, call within the same week. Same-day appointments are typically available.
