Leak Detection in Los Alamitos, CA

Leak detection in Los Alamitos pinpoints hidden water leaks in slabs, walls, ceilings and buried lines, using pressure tests, listening equipment and thermal imaging, so only the necessary section has to be opened. A meter that moves with every tap off is the clearest sign of a hidden leak. Call (708) 350-9399 and ask whether your Los Alamitos address is covered.

Where do hidden leaks happen in Los Alamitos homes?

Los Alamitos is a small Orange County city where the Joint Forces Training Base takes up roughly half the land. The civilian side is mostly 1950s and 1960s single-family homes plus apartments and townhomes. Supply lines in or under concrete slabs, pinholes in aging copper, corroded galvanized pipe in walls, and buried service lines between the meter and the house are the usual suspects. Irrigation lines and toilet flappers cause many high bills, too.

How can you check for a leak yourself?

Turn off every faucet, appliance and irrigation zone, then watch the meter's leak indicator for 15 to 30 minutes. If it moves, water is escaping somewhere. Close the house shutoff. If the meter still moves, the leak is probably underground between the meter and the house. Use a few drops of food coloring in each toilet tank to check flappers. See our high water bill guide.

What happens during professional leak detection?

Providers typically isolate hot and cold lines, pressure-test them, then use acoustic listening gear and sometimes thermal cameras to narrow the location. Once it's found, the choice is between a spot repair, rerouting the line through the attic or walls, or a partial or full repipe if the pipe is failing in several places.

Who handles leaks at the meter?

Water in Los Alamitos comes from Golden State Water Company's West Orange County system, which blends local groundwater with imported water, per the Golden State Water Los Alamitos system. Leaks at or before the meter, or in the street, are the water provider's responsibility, so contact them first. Leaks on the house side of the meter are a private plumbing repair.

What's different about leak detection in Los Alamitos?

Los Alamitos is in Orange County, so permits go through the City of Los Alamitos rather than an LA County office. Golden State Water also runs local PFAS treatment projects, which is useful context if you are considering home water filtration. Whether you live near Little Cottonwood Park or Laurel Park, the call works the same way: describe the problem, give your address or cross streets, and ask whether your address is covered.

What should you have ready when you call?

The result of the meter test with everything off
Where you've seen signs: warm floors, damp spots, stains or a wet yard
Your recent water bills, if usage has jumped
Whether the home is on a slab, and whether it's been partly repiped
Your Los Alamitos address or nearest cross streets, so coverage can be checked

The more specific you can be, the easier it is for the provider to tell you on the call whether the job is a fit and what a visit would involve.

What does leak detection cost?

Leak Detection questions in Los Alamitos

What are the signs of a slab leak?

Common signs include the sound of running water when nothing is on, a warm spot on the floor (for hot-water lines), damp or cracked flooring, mildew smells, a water heater that runs more than usual, and a meter that moves with everything off. A sudden jump in your water bill is often the first clue. If you notice these, do the meter test, then call for leak detection. Finding the exact location means less of the floor has to be opened, which usually saves more than the cost of detection.

How much does leak detection cost?

Angi's 2026 slab leak guide puts slab leak detection at about $150 to $400, with an average of around $280. Repair costs vary far more, depending on whether the leak is spot-repaired, rerouted or addressed with a repipe, and what flooring has to be opened. In Los Alamitos, the leak's location and your home's construction drive the price. Treat national figures as a planning guide. Check whether your homeowners policy covers access and resulting damage, and keep the detection report.

Will my insurance cover a hidden leak?

It depends on your policy. Many homeowners policies cover sudden water damage and the cost of accessing the leak, such as opening a floor or wall, but don't cover repairing the pipe itself or damage from a long-term leak. Read your policy, photograph the damage and keep the leak detection report and invoices. Ask your insurer before major work if you can. A provider can usually document the leak location and the pipe's condition, which helps with any claim.
