Find hidden leaks precisely. No guesswork. No unnecessary demolition.
Most water damage in San Marino homes doesn't come from dramatic failures. It comes from the slow leak nobody noticed for eight months — a pinhole behind a vanity, a slab leak warming a corner of the floor, an irrigation line bleeding into the lawn so quietly that only the water bill ever flagged it.
That's the work we specialize in. Rowson's water leak detection service in San Marino, CA is built around precision: finding the exact source before anything gets cut, dug, or torn out. We use the same acoustic, thermal, and pressure-based equipment leak detection specialists use across the country.
Precision tools. Honest recommendations. Minimal disruption.
A slab leak is the one homeowners dread — water escaping from a pipe buried in the concrete foundation itself. The signs are subtle: a warm patch on the floor, an unexplained spike on the water bill, the faint sound of running water when nothing is on.
Our slab leak detection near me service uses electronic amplification and thermal imaging to pinpoint the exact location, often within inches. We discuss spot repair, rerouting, or full repipe options honestly.
Get Slab Leak Detection NowCopper pipe leak repair calls usually start the same way: a brown spot on a ceiling, a slightly damp baseboard, a musty smell that wasn't there last month.
We isolate the affected section, pressure-test surrounding lines, and replace with durable material. For widespread issues, we'll discuss full repiping honestly.
Fix Pinhole Leaks TodayA leak in a buried supply line can run for months before anyone notices. Our water leak detection services near me include yard line work — locating breaks in the main supply, irrigation breaks, and outdoor faucet repair.
Locate Yard Line LeaksThe leakiest fixture in most San Marino homes is the toilet. A worn flapper or failing fill valve can waste hundreds of gallons a day silently. We also handle dripping faucet repair and washer replacement.
Stop Wasting Water NowWhen you suspect a leak but can't locate it, we run a static pressure test on the entire system. It tells us within minutes whether the home is losing water — and where.
Schedule Pressure TestA simple fitting replacement or short pipe section. Minimal cost and disruption.
Drywall repair, insulation replacement, possible mold remediation, higher insurance deductibles.
