Undetected leaks can expose commercial properties in Los Angeles, Ventura County, and the San Fernando Valley to water damage, mold growth, and increased operating costs. We perform commercial leak detection and water leak repair using advanced technology that helps us locate plumbing problems quickly and limit disruptions for business owners.
Common Commercial Leak Problems
Commercial plumbing systems can be large and develop leaks in many locations.
Common commercial plumbing issues include:
- Hidden wall leaks, ceiling leaks, or leaks beneath concrete slabs
- Underground leaks in water lines that cause pressure loss or water waste
- Plumbing leaks that lead to water stains or ceiling damage
- Slow leaks that contribute to mold growth or structural damage
Signs You May Have a Hidden Leak
Commercial and industrial plumbing issues are not always immediately visible.
Watch for signs of plumbing leaks like:
- High water bills
- Damp spots
- Stains
- Bubbling paint
- Musty odors
- Mold
- Reduced water pressure
- Running water sounds when fixtures are off
Early leak detection is critical to water damage prevention and minimizes downtime.

SoCal Commercial Leak Detection Services
Non-Invasive Detection
We use specialized non-invasive detection equipment to locate hidden leaks without opening walls or flooring unnecessarily.
Slab Leak Detection
Leaks beneath concrete slabs can be difficult to pinpoint. Our slab leak detection services help identify the affected area before pipe repairs begin.
Water Line Leak Detection
We locate underground leaks and internal water line leaks so repairs can focus on the source of the problem.
System-Wide Leak Assessments
For recurring or multiple leaks, we can evaluate the commercial or industrial plumbing system to identify problem areas that require attention.
Advanced Technology for Non-Invasive Detection
Depending on the property and suspected plumbing issue, we use leak inspection tools and methods such as:
- Acoustic leak detection: Helps plumbers listen for water sounds.
- Infrared leak detection: Identifies temperature differences for moisture detection.
- Pressure testing: Confirms water loss by checking current water pressure.
- Gas tracer detection: Uses a tracer gas to help pinpoint leaks.
These water leak detection methods allow for faster commercial plumbing diagnostics with less disruption.
Commercial Plumbing Leak Repair Solutions
After leak source identification, we recommend a leak repair based on its location, severity, and pipe condition.
Plumbing solutions may include:
- Targeted pipe repairs
- Replacement of damaged pipe sections

Our goal is to provide durable pipe repair and water damage prevention with a fast turnaround.
