A Story from the Field
A couple of years ago, we got a call from a family living in the Harbor Boulevard area near the South Coast Metro. The homeowner noticed their water bill had doubled over three months, but couldn’t find any visible leaks anywhere in their house. They had already called two other companies who couldn’t locate the problem and suggested tearing up their entire living room floor. When our team arrived with our advanced sonic detection equipment, we pinpointed the leak within 30 minutes – it was running under their kitchen island, not the living room. We were able to access the leak through a small opening in their garage wall, saving them thousands in unnecessary floor replacement. The whole repair took just one day, and their water bill went back to normal the next month.
Understanding Slab Leak Detection Technology

Slab leak detection has come a long way from the old days of guessing and digging. Today’s high-tech equipment lets us find leaks without breaking your floors or walls. Our process starts with electronic listening devices that can hear water moving through pipes buried in concrete. These sensitive instruments pick up the sound of water escaping from pipes, even when it’s several feet underground.
Next, we use thermal imaging cameras that show temperature differences on your floors. Since leaked water creates cooler spots where it pools under the slab, these cameras create a heat map of your home that shows exactly where water is collecting. The latest technology also includes ground-penetrating radar that creates pictures of what’s happening beneath your foundation.
After we locate the general area, we use pressure testing to confirm the leak and measure how much water you’re losing. This step helps us determine if the leak needs immediate repair or if we can schedule it at your convenience. The whole detection process usually takes 2-3 hours, and you’ll know exactly where your leak is and what it will cost to fix before we start any repair work.
Common DIY Detection Mistakes
Many Costa Mesa homeowners try to save money by attempting their own leak detection, but this often leads to bigger problems. One major mistake is using a regular stethoscope or basic listening device from the hardware store. These tools can’t distinguish between normal pipe sounds and actual leaks, leading people to dig in the wrong spots and damage their floors unnecessarily.
Another costly error is assuming that wet spots on floors automatically mean the leak is directly underneath. Water can travel several feet through soil and sand before it surfaces, especially in Costa Mesa’s sandy ground conditions. We’ve seen homeowners tear up bathroom tiles only to discover the leak was actually under their kitchen, 15 feet away from where the water appeared.
