Leak Detection in Santa Cruz, CA

Leak detection typically runs $200–$400 depending on the complexity of the investigation and the type of leak suspected. Slab leak location — which requires acoustic and thermal equipment — is toward the higher end. We quote before starting and the detection fee is separate from any repair work, which we quote once we've found the source.

Not during detection. We use non-invasive acoustic listening equipment and thermal methods to pinpoint the leak location before recommending any access. Once we've identified the exact location, we discuss the least invasive repair option — which for many leaks means a small, targeted access point rather than opening a full wall or cutting a large section of slab.

First, do the meter test: turn off every fixture, appliance, and irrigation valve in the house, then check whether the water meter dial is still moving. If it is, you have an active leak somewhere. Common causes in Santa Cruz homes include a running toilet (flapper leak — often silent), a dripping irrigation zone, an underground supply line leak, or a slab leak. Call us and we'll systematically find it.

A slab leak is a leak in a pressurized pipe (either hot or cold water supply) that runs under your concrete slab foundation. They're serious for two reasons: the water escaping underneath erodes soil and can crack or heave the slab over time, and the constant moisture creates conditions for mold growth in the subfloor materials above. Detected early, slab leaks can be repaired with a targeted cut through the slab. Left long enough, they can require foundation remediation.

Most ceiling wet spots are either a plumbing leak from above (a supply line, drain, or toilet connection in the floor above) or a roof leak. If the stain is directly below a bathroom or kitchen, plumbing is the likely cause. If it's below an exterior roof line or appears after rain, roofing may be the issue. We investigate plumbing-related ceiling leaks — if we determine it's a roofing issue, we'll tell you and point you to a roofer.

Yes — and in Santa Cruz's coastal climate, mold grows fast in the presence of persistent moisture. A hidden wall leak that drips slowly for months will almost certainly produce mold in the insulation and framing behind the drywall before it becomes visible. This is one of the primary reasons we strongly encourage not ignoring the warning signs. Early detection and repair prevents mold remediation — which is far more expensive and disruptive than fixing the pipe.
