How we find a hidden water leak in San Diego

A water leak in San Diego rarely shows up where it starts. Coastal soil hydrology through Oceanside, Carlsbad, Encinitas and the western bayfront moves escaping water sideways along sandy overburden and sandstone bedding, so the stain on a baseboard can sit twenty feet from the break. Inland, expansive valley clay in Escondido, El Cajon and Santee absorbs the water entirely until pressure finally forces it up through a control joint.

The sequence

We shut the house down at the meter and watch for movement, isolate hot from cold and irrigation from domestic, then put a correlator on the failing loop. Thermal imaging picks up hot-side breaks through tile and hardwood without lifting anything. Where the leak is too slow or too quiet to hear, inert tracer gas is introduced into the drained line and surfaced with a hydrocarbon sniffer.

What you get

A marked location, photo documentation, pressure readings, and a plain statement of what failed and why. Take that to your own plumber or let us open, repair and restore. If the failure is under concrete, keep reading on our slab leak detection page, and see the cost breakdown before you commit to anything.
