Slab Leak Detection & Repair

A slab leak is a leak in a water line that runs under or through your home's concrete foundation. Because the water soaks into the soil and slab, it can run for weeks before you see it. Many Inland Empire homes are built on slabs, so these leaks are common here. Warning signs include a rising water bill, warm spots on the floor, and the sound of running water.

Plumbers find slab leaks with pressure testing, acoustic listening equipment, and electronic and thermal tools, so no demolition is needed to locate the leak. Pressure testing shows whether the hot or cold side is leaking. Acoustic gear picks up the sound of escaping water through the concrete, and thermal tools spot heat from hot water leaks. Then we mark the spot so any opening stays small.

Yes, a water meter test is a good first check. Turn off every faucet, toilet, appliance, and sprinkler, then look at your meter's leak indicator and write down the reading. Wait two hours without using any water and check again. If the reading changed, water is leaking somewhere. Rule out a running toilet first, then see our slab leak signs guide.

A warm spot on a tile or concrete floor often means a hot water line is leaking under the slab. The escaping hot water heats the floor above it, and you may also hear your water heater running more than usual. Get it checked soon, because the leak wastes water and energy and can soak the slab and flooring over time.

A reroute is often better when the leak sits under expensive flooring or a hard-to-reach area, or when the pipe under the slab is aging. It caps the old line and runs a new one through the walls or attic, so no concrete is broken. A spot repair can cost less for a single leak in pipe that is otherwise in good shape. After repeat leaks, a repipe may make more sense. We quote each option up front.
