A spinning water meter, a warm spot on the floor, or a stain that keeps growing means water is going somewhere. We find it without opening up more of your home than necessary.
Hidden leaks are the most expensive kind of water damage because they run for weeks before anyone notices. By the time a ceiling stain shows up or a hardwood floor starts cupping, the water has often soaked insulation, framing and subfloor across a much bigger area than what you can see.
We use thermal imaging cameras, pin and pinless moisture meters, and acoustic listening equipment to trace water to its source. The goal is to pinpoint the leak and map exactly how far moisture has spread, so cutouts are small and targeted, not exploratory.
In Napa we find a lot of leaks in aging galvanized supply lines in pre-1960 homes, copper pinhole leaks, failed shower pans, and slab leaks in homes built on concrete foundations in south Napa and American Canyon. After the 2014 South Napa earthquake, some homes were left with stressed pipe joints that still fail today.
These steps limit damage while help is on the way.
We ask what you have noticed and check your water meter for flow with all fixtures off.
Thermal imaging and moisture meters show wet areas behind walls, under floors and above ceilings.
Acoustic tools and targeted testing isolate the exact pipe, fixture or seal that is failing.
If water has spread, we set up drying and handle the repair once the leak is fixed.

City of Napa water customers can check their meter at the street. If the low-flow indicator is spinning with every faucet and appliance off, water is leaving the system somewhere. Unusually high bills, the sound of running water at night, or a section of floor that feels warm are all signs worth a call. Napa homes built before 1960 often still have galvanized supply lines, and the 2014 South Napa earthquake stressed joints in many older houses. Slab homes in south Napa and American Canyon see under-slab leaks. Both are common sources of hidden water.
Most leaks are located the same visit. Drying of affected areas takes three to five days, then repairs are scheduled after the plumbing fix.

Yes. Homes built on concrete slabs, common in newer parts of south Napa and American Canyon, can develop leaks in pipes under the slab. We locate them so the plumber can repair or reroute with minimal disruption.
