EZ Plumbing provides leak detection services for residential and commercial properties when a water leak needs a clearer diagnosis before repair work begins. We focus on practical troubleshooting, clear communication, and recommendations based on the actual source of the leak.
Depending on what is found, the next step may involve slab leak repair, repipe work, water heater repair, or another plumbing repair path.
When Leak Detection Is Recommended
Leak detection is often recommended when there is unexplained water, a sudden increase in the water bill, the sound of running water, damp drywall, staining on a ceiling, moisture inside a wall, or signs that a slab leak may be present below the floor.
Finding the source first helps avoid guesswork and makes it easier to recommend the right repair instead of opening walls or floors unnecessarily.
Hidden Leak Detection
Hidden leak detection is used when the leak is not immediately visible but there are signs that water is escaping somewhere in the system. This can include warm spots on floors, damp cabinets, musty odors, bubbling paint, warped materials, or isolated moisture that does not have a clear source.
In many cases, locating the leak accurately is the most important first step because it determines whether the issue is isolated or part of a larger pipe problem.
Slab, Wall, and Ceiling Leak Detection
Leak detection may involve tracking a slab leak below the foundation, a wall leak inside the building envelope, or a ceiling leak coming from a pipe above. These problems can show up differently, but all of them benefit from a careful diagnostic process before repairs begin.
If the issue points to a damaged line under the slab, we may recommend slab leak repair. If the piping is aging or failing in multiple locations, repipe work may be part of the longer-term solution.
Residential Leak Detection
For homes, leak detection is often needed when the plumbing system is leaking behind walls, below floors, or in ceilings where the source is not immediately visible. A clear diagnosis helps homeowners understand whether the problem is isolated, structural, or part of a larger piping condition.
Commercial Leak Detection
Commercial leak detection is often helpful in offices, retail spaces, restaurants, multifamily properties, and other occupied buildings where hidden water damage can affect operations, tenants, or interior finishes before the source has been confirmed.
We can also coordinate leak detection with broader commercial plumbing service when a property needs both immediate troubleshooting and a practical repair plan.

Leak Detection FAQs
How do you find a leak without tearing open walls?
Electronic and acoustic detection — we trace the sound and signal of escaping water to a precise location before anything is opened. The repair opening ends up inches wide instead of a demolition project.
What are the signs of a hidden water leak?
An unexplained jump in your water bill, the sound of running water with every fixture off, warm spots on floors, musty smells, or a water meter that spins when nothing is on. Any one of those is worth a call.
Can you detect leaks under concrete slabs?
Yes — slab leaks are a specialty. We locate them electronically and usually repair by re-routing the line overhead rather than jackhammering the slab. See our slab leak repair service for the full approach.
Do you find pool and irrigation leaks?
Yes — pool plumbing, spa lines, irrigation systems, and yard supply lines. Outdoor leaks waste enormous water volumes and often show up first as a soggy patch or a bill spike.
How much does leak detection cost?
It is a flat-rate diagnostic service, and the fee is applied to the repair if you proceed with us. You get the precise location and a written repair price before deciding anything.
Is a hidden leak really an emergency?
An active one, yes — water damage compounds daily, and mold follows moisture. Shut off the main if you can and call (818) 908-2710; we answer 24/7.
