Slab Leak Repair & Leak Detection in St. George
Precise answers instead of exploratory holes
Most St. George homes are built on a concrete slab with the supply lines running beneath it, so a hidden leak often means slab leak repair in St. George rather than a quick fix under a sink. Water rarely surfaces where a pipe actually broke. It runs along a joist, soaks into drywall or seeps down through the soil under the slab, and in our dry heat it can evaporate before it pools. That’s why so many homeowners first notice a leak on the water bill. Guessing at the source means cutting holes and hoping.
Our plumbers locate leaks with tools built for the job. Pressure testing isolates which line is losing water. Acoustic equipment listens through concrete and drywall for the hiss of an escaping stream, thermal imaging spots the temperature change wet materials leave behind, and moisture meters confirm the path. Once we know exactly where the problem is, you get a clear explanation and a price for the leak repair. For buried supply lines, we’ll talk through water line options.
- Acoustic Listening We hear water escaping through slab and drywall.
- Thermal Imaging Wet materials show up as cool or warm patches.
- Pressure Testing Isolates which line is losing water.

Leak detection questions in St. George
How do you find a leak without tearing out walls?
We combine several methods. Pressure testing tells us which line is leaking, acoustic sensors pick up the sound of escaping water through floors and drywall, and thermal cameras show where wet materials are hiding. Moisture meters confirm what the camera sees. Together they let us mark the spot before we cut anything.
What causes slab leaks in Washington County?
Expansive desert soil moves with heat, irrigation and the occasional heavy rain, putting stress on lines under the foundation. Very hard water thins pipe walls from the inside over time. Hot water lines are the usual culprits because heat speeds both processes. A water softener helps protect lines that are still sound.
What happens after you find the leak?
Your plumber shows you where the leak is and explains the repair options, from a spot repair to rerouting a line around the slab. You get the price for each before any work begins. If you approve, we can usually start the leak repair right away.
Can a leak make my water heater run nonstop?
Yes. If a hot water line is leaking, the heater keeps refilling and reheating cold water to replace what’s lost. You may hear it firing often or notice a higher gas or power bill. That’s one of the more reliable clues that the leak is on the hot side.
Do you offer leak detection after hours?
Yes. If water is actively showing up in your home, our plumbers respond 24/7, including nights, weekends and holidays. We’ll help you shut off the water first, then find the source. For slower leaks, we can schedule a visit at a time that suits you anywhere from St. George to Hurricane.
What does slab leak repair in St. George, UT cost?
It comes down to where the leak is and how we reach it. A leak under the slab can be fixed by opening the floor at the exact spot or by rerouting that line overhead through the attic and walls, and each route has a different price. Pipe material, the flooring that has to come up and go back, and whether the camera and pressure tests turn up one leak or several also matter. Your plumber locates the leak first, then gives you a written, upfront price for each option before any concrete is touched. The $50 off any plumbing service offer applies.
