Customer Reviews

Cesar came out for leak detection, found the issue, and after weighing our options, we chose to repipe. He repiped the entire house himself in just two days, taking time to explain each step, which we really appreciated. Allana handled the water damage assessment and even initiated the insurance claim, which was a big help. From Chuck on the initial call to Cesar, Allana, and Tom (financing), the service was excellent—especially Cesar. We’d recommend him anytime! Michele G

I had had higher water usage for two months and spent a weekend checking the water dial. I had a leaking water line from the street to the house. The leak detection plumber diagnosed the problem the same day that I called. They arrived the next day and worked for several hours in extreme heat. The line was replaced and there is no more leak. I am very satisfied! Mary J

Frequently Asked Questions

What are the primary types of leak detection?

The first step in leak detection is personal observation by a plumber. Sights and sounds often point an experienced professional to the source. But leaks deep within the plumbing system may require specialized equipment like acoustic leak detection (sound-based), thermal imaging (heat signature mapping), and moisture metering (measuring dampness in materials). Each method helps accurately locate leaks without invasive digging or demolition.

How to detect water leaks?

To detect water leaks, look for signs like higher water bills, damp spots, musty odors, or the sound of running water when fixtures are off. Professional leak detection services start with an inspection of the property, but may use tools like acoustic sensors, infrared cameras, and pressure testing to pinpoint hidden leaks accurately.

What to do if you have a water leak?

If it’s a local leak around a specific toilet or sink, turn off the water valve beneath the fixture. If it’s a hidden steady leak, shut off your main water supply immediately, avoid using affected areas, and contact a licensed plumber or leak detection specialist. Prompt action can prevent costly water damage and mold growth.

Who is responsible for a water leak?

Homeowners are typically responsible for leaks on their property, including inside the home and between the water meter and the house or structure. Leaks beyond the meter or in public lines are usually the utility company's responsibility.
