Dispatch & scheduling
(619) 923 - 0033Leaks that can't take a building offline
In a commercial San Diego property the cost of a leak is rarely the water. It's the closed floor, the displaced tenants, the health inspection and the claim. Our commercial work is structured to minimize all four: isolate by riser and zone at night, locate electronically, hand you a marked, documented finding before doors open.
Property types we work
Apartment and condo associations, hotels and short-term rentals, restaurants and commercial kitchens, medical and dental offices, retail centers, warehouses and light industrial. Multi-unit buildings get sub-metering and unit-by-unit isolation so responsibility is established with data rather than argument.
San Diego structural realities
Coastal commercial slabs near the bay and along the North County corridor sit in chloride-bearing fill that corrodes under-slab copper and buried steel gas line alike. Inland business parks on expansive valley clay move seasonally, shearing rigid supply and fire-loop plumbing at joints. Both call for the same discipline used on our slab leak detection and gas leak detection work, scaled to a building.
Documentation
Written findings, thermal and photo evidence, pressure logs, and a scaled sketch of the located failure. Combine with underground utility locating when excavation is on the table.
What we locate
Leak detection services in San Diego
Every call starts with electronic locating — acoustic, thermal, tracer gas and pressure isolation — so the repair in San Diego is surgical instead of exploratory.

Water Leak Detection
Acoustic correlation, thermal imaging and tracer gas to pinpoint pressurized water line failures inside San Diego walls, ceilings and service laterals — no exploratory demolition.

Pool Leak Detection
Dye testing, pressure isolation and hydrophone listening on pools, spas and plumbing loops losing water to dry Southern California evaporation-plus-leak conditions.
Learn more
Slab Leak Detection
Tracking hidden line failures beneath San Diego foundations — hot-side pinholes, copper corrosion and post-tension slab breaches located to the square foot before a single cut is made.
