Leak Detection Services
Prime Leak Detection offers leak detection services in Los Angeles and Orange County from two offices, one in Chatsworth and one in Irvine. We find water that’s escaping from pipes inside walls, under slabs, beneath yards and in pools. Then we mark the spot so whoever opens it knows where to start.

Leak detection is a specialty,
separate from general plumbing.
A lot of people call a plumber first, and that’s a fair place to start. Finding a hidden leak takes its own gear, though: pressure gauges, acoustic ground microphones, thermal cameras, and the time to use them properly. If a plumber couldn’t find it, this is the part of the job we handle.
Services
Our leak detection services in Los Angeles and Orange County
Residential leak detection
Stains, a musty smell or a meter that keeps moving. We trace hidden leaks in walls, under floors and behind showers.
Home leak detection
Swimming pool leak detection
Losing more water than evaporation explains? We test the shell, fittings and buried lines to find where it’s going.
Pool leak detection
Slab leak detection
Warm spots on the floor or running water you can’t place. We locate leaks in the lines under your concrete, so the repair can usually start at the mark.
Slab leak detection
Underground leak detection
A wet patch in the yard or a meter that never stops. We trace main water lines and buried pipes before anyone digs.
Underground leak detection
Thermal imaging leak detection
Infrared cameras read the temperature changes moisture leaves in drywall, tile and ceilings. A non-invasive first look.

Apartments, offices, retail and HOA properties. We plan access around tenants and test long pipe runs one section at a time.

FAQ
Leak detection services: common questions
What’s the difference between a plumber and a leak detection company?
A plumber installs and repairs pipes and fixtures. A leak detection company finds where a hidden pipe is leaking. Plumbing leak detection is our specialty, so the repair starts from a marked spot instead of a guess.
Do you serve both LA and Orange County?
Yes. Our main office at 9941 Canoga Ave in Chatsworth covers Los Angeles County, with the San Fernando Valley as its core area. The office at 18100 Von Karman Ave in Irvine covers central Orange County, from Tustin and Costa Mesa to Newport Beach. See leak detection in Irvine for the cities we reach from there.
What do I need to tell you when I book?
The address, what you’ve noticed and when it started. Tell us if the bill changed, whether the meter moves with everything off, and if there’s a pool or sprinklers. For a rental or HOA property, say who can give us access.
