A hidden water leak is one of the most expensive problems a homeowner can ignore. Water under a slab or inside a wall cavity can run for months before it shows up as warped flooring, mold, or a foundation issue — and every month it shows up on your LADWP bill.
Our leak detection service uses acoustic listening equipment, pressure testing, and thermal imaging to locate the leak point precisely. Many Los Angeles homes built from the 1950s through the 1970s have copper lines running under the concrete slab; over time, hard water and soil movement cause pinhole leaks that are impossible to find by guesswork.
Once the leak is located, you get repair options with flat-rate prices: a direct spot repair through a small access opening, rerouting the line through the attic or walls to abandon the failing section, or epoxy lining the pipe from the inside. We'll explain the trade-offs so you can choose what fits the house and your budget.
Everything we handle under leak detection & repair across Los Angeles, Orange County, the Valley, and the Westside.

Our reviews come from real emergencies — and how we handled them.
“We had a sewer backup on a Sunday night — our laundry room was completely flooded. I called Rooter Rescue at 9 PM and they had a tech at the door within 45 minutes. He cleared a major root intrusion in the main line and had everything flowing again by midnight. I couldn't believe the response time. They're the only plumber I'll ever call.”

“My water bill had been climbing for months and I couldn't figure out why. Rooter Rescue used electronic detection equipment to find a slab leak under my kitchen floor without ripping up a single tile — found it in under an hour. The repair was clean, fast, and came in exactly at the estimate. These guys are total pros.”
Mike T.

“My water heater died on a Friday morning. I called three plumbers — two couldn't get to me until next week. Rooter Rescue had a new unit installed that same afternoon. The tech explained every option clearly, gave me a fair price without any pressure, and left the work area cleaner than he found it. Five stars isn't enough.”

Straight answers to what homeowners ask us most about leak detection & repair.
A slab leak is a leak in a water line running under or inside your home's concrete foundation. In Los Angeles they're common in homes with copper supply lines poured into the slab. Hard water, soil movement, and abrasion against concrete eventually wear pinholes in the pipe.
