Customer Success Story · Statewide

The Alvarez Family in Downtown LA, Los Angeles noticed a water bill that had crept up for two billing cycles with no clear reason and wasn't sure how serious it was. Because the diagnostic came first, nothing got opened up on a guess. The leak was marked in that same visit, and the repair crew only had to open a small section instead of the whole area.

What California homeowners are saying

★★★★★

“The floor in our hallway had a warm spot for weeks. They found the slab leak in under an hour with the listening equipment and marked a tiny area instead of tearing up the whole hallway. Huge relief.”

MTMarcus T. · Los Angeles, CA
★★★★★

“Our water bill jumped for two months straight and we couldn't find why. Turned out it was a slow leak behind the water heater. Professional, on time, and explained everything on the spot.”

PRPriya R. · Los Angeles, CA
★★★★★

“Salt air had corroded a fitting outside near the meter box. They traced it with the acoustic equipment without digging up my whole side yard first. Appreciated the straightforward report.”

DKDaniel K. · San Diego, CA
★★★★☆

“Good experience overall, technician was knowledgeable and thorough. Took a little longer than expected but they were clearly being careful about pinpointing the exact spot before marking it.”

AMAngela M. · San Diego, CA
★★★★★

“Old Victorian with plaster walls everywhere, so I was dreading this. They used thermal imaging and found the leak behind one wall panel instead of opening up the whole room. Saved us a big repair bill.”

CBChris B. · San Francisco, CA
★★★★★

“Ground near our garage had been soft for a while. Turned out to be the main line. They marked the exact dig spot and our plumber only had to open a two-foot section instead of the whole path.”

WLWei L. · San Francisco, CA
★★★★★

“We had slow drains for weeks and figured it was just old pipes. Camera inspection showed root intrusion about 30 feet out. Clear video, clear explanation, no surprises.”

SOSamantha O. · San Jose, CA
★★★★☆

“Solid, professional service. Arrived within the scheduled window and walked me through the sewer camera footage on the spot so I understood exactly what was going on.”

Frequently asked questions

How do I know if I have a hidden water leak?Toggle answer
Common warning signs include a water bill that rises without a change in usage, a water meter that keeps moving with every fixture off, warm spots on flooring, musty odors, or unexplained cracks in walls or slab. If you notice any of these, a professional leak detection inspection can confirm whether a leak exists and where it's located.
Is leak detection non-invasive? Will you need to cut into my walls or slab?Toggle answer
Our standard approach uses acoustic listening equipment, thermal imaging, tracer gas, and camera inspection to locate a leak before any cutting or digging happens. In most cases we can narrow the leak to a small, specific area, which keeps any necessary access work limited and targeted.
How long does a leak detection appointment take?Toggle answer
Most residential inspections take between 45 minutes and two hours depending on the size of the property and the type of leak suspected. Larger commercial properties or multiple suspected leak points may take longer.
Do you offer same-day or emergency leak detection in California?Toggle answer
Yes, we offer same-day appointments across our California service area for active leaks, and prioritize urgent calls such as active water intrusion or suspected gas leaks.
What equipment do you use to find leaks?Toggle answer
Depending on the leak type, our technicians use acoustic listening discs and ground microphones, infrared thermal imaging cameras, tracer gas equipment, static pressure testing, and push or drain camera inspection systems.
Does homeowners insurance cover leak detection?Toggle answer
Coverage varies by carrier and policy, and often depends on whether the leak is considered sudden and accidental versus a long-term, gradual issue. We provide a written diagnostic report that you can submit with a claim, and recommend confirming specifics directly with your insurance provider.
