Leak Detection & Smart Shutoffs · Los Angeles & SoCal
Find the hidden leak — without tearing up your home.
Find hidden leaks and install automatic leak-detection devices.
A water bill that jumps, the sound of running water when everything is off, or a warm spot on the floor can all point to a hidden or slab leak. We locate it without opening walls or floors to go looking.
Then we help you stop the next one: smart shutoff valves watch your water use and close the main automatically if they detect a leak — even when you're away.

Leak Detection & Smart Shutoffs: common questions
What is a slab leak?
A leak in a water line running under your home's concrete foundation — common in older Southern California homes.
How does a smart shutoff work?
It's installed on your main water line, monitors flow, and closes the valve automatically when it detects a leak. Many send alerts to your phone.
