Find the Leak Before It Finds Your Foundation

Not every leak announces itself. Many hide behind walls, under concrete slabs, or underground — slowly driving up your water bill, feeding mold, and threatening your foundation long before you see a drop. The sooner a hidden leak is found, the less damage it does.

ASI’s licensed plumbers use electronic and acoustic leak-detection equipment to locate the exact source without tearing your home apart. Since 1952, San Diego homeowners have trusted The White Glove Guys to find the problem precisely and fix it right — including slab leaks, our specialty. And we never charge extra for nights or weekends.

Warning Signs

Signs You Have a Hidden Leak

Noticing any of these? Call us before the damage spreads.

Unexplained High Water Bills

A water bill that jumps without a change in usage is one of the clearest signs of a hidden leak somewhere in your system.

Running Water You Can Hear

If you hear water running when every fixture is off, water is escaping somewhere it shouldn't.

Warm Spots on the Floor

A warm area on a slab floor often signals a hot-water slab leak beneath the foundation.

Mold, Mildew, or Musty Smells

Persistent moisture from a hidden leak breeds mold and leaves a musty odor, even when nothing looks wet.

Low Water Pressure

A drop in pressure can mean water is leaking out of the line before it reaches your fixtures.

Cracks in Walls or Foundation

Water undermining the soil beneath your home can cause new cracks in walls, floors, or the foundation itself.

I recently had maintenance done on my AC and furnace by ASI, and I wanted to highlight the great experience I had—especially with the technician, Jesus. From start to finish, Jesus was extremely professional, thorough, and clearly very knowledgeable about his work. He took the time to carefully service and clean both the AC and furnace, making sure everything was running properly and efficiently. What really stood out to me was his attention to detail—he didn’t rush the job and even went the extra mile by cleaning the outside of the unit, which I truly appreciated. On top of that, his customer service was outstanding. He was friendly, respectful, and took the time to explain what he was doing, which gave me a lot of confidence in the work being performed. Overall, I’m very satisfied with the service and the level of care provided. I will definitely be using ASI again in the future and would highly recommend requesting Jesus if you want the job done right.

After 21 years of faithful service our heater finally gave out. ASI came to the house and we went over a few options as to repair or replace. We elected the latter, and the very next morning ASI was on site with the new heater. Within 6 hours, Sebastian Garcia and his helper had the new heater installed. Sebastian spent some time explaining how to use the new thermostat, which is so much easier to use than the previous one. By the time they left the garage was clean and all the old stuff was carted away. A great job by an outstanding company. This morning I checked my old paperwork and found that the new heater and thermostat were only a couple of hundred dollars more than the ones I had purchased 21 years ago. ASI really offers good prices and great equipment. A special thanks to the service manager Joe Gondak for keeping in touch with the crew to insure there were no problems during the installation
FAQ

Leak Detection Questions, Answered

We use non-invasive electronic and acoustic equipment to pinpoint a leak’s exact location, so we only open the one spot that needs repair — not your whole wall or floor.

Aging or corroded pipes, shifting soil, high water pressure, and slab movement are common culprits in San Diego homes. We identify the cause, not just the symptom.

Yes — slab leak detection and repair is one of our specialties. We locate leaks beneath the foundation and recommend the least-invasive repair.

It depends on the situation, but we always give you upfront pricing before any work begins — no surprises.

Absolutely. A slow, hidden leak can rot framing, ruin flooring, feed mold, and undermine a foundation over time. Early detection saves money.

Coverage varies by policy. Insurers often cover sudden water damage but not gradual leaks — finding and documenting the source early helps your claim.
