A slab leak losing a single gallon per hour moves more than 8,700 gallons of water in a year — almost all of it into the soil under your foundation. That's not a number we invented; it's straightforward arithmetic on what a pinhole-sized breach in a pressurized line actually does over time. And it's why slab leak work isn't something a general plumber should approach with a stethoscope and a guess.
Carlos Plumbing Service has handled slab leak detection in Austin homes for three generations of family ownership. We've watched the equipment improve, the methods refine, and the diagnostic precision get to a point where opening drywall on the wrong wall is no longer a tolerable mistake.
Isolates the exact sound signature of escaping water. We narrow the leak to a small working radius — often a single tile — saving you time and money on repair access.

The variance isn’t necessarily dishonesty. It’s diagnostic precision — or the lack of it.
A plumber who hasn’t precisely located the leak is pricing for an area... A plumber who has located the leak within an 18-inch radius is pricing for a known-scope repair...
The question to ask any plumber isn’t “what does it cost?” It’s “where exactly is the leak?”
