A slab leak is a leak in a water line that runs underneath the concrete foundation of your home. Because it is hidden, the biggest risk is not the leak itself but guessing wrong about where it is and tearing up the wrong part of your floor. Accurate detection solves that. At Prescott Slab Leak Repair, we locate the leak precisely first, then open only the small area we need to fix it.
We have been detecting slab leaks across Prescott and Yavapai County since 2014. The goal on every call is the same: confirm the leak, pinpoint it, and give you a clear plan, without unnecessary demolition.
How we detect a slab leak
There is no single tool that finds every leak, so we layer several proven methods. Together they confirm that water is escaping and narrow the location to a small, specific spot.
Pressure testing
We isolate your plumbing and watch for pressure loss. A line that will not hold pressure confirms there is a leak in the system and tells us whether it is on the hot or cold side. This is the yes-or-no step that rules a slab leak in or out before we spend time pinpointing.
Acoustic leak detection
Water escaping under pressure makes a distinct sound as it hits the concrete and soil. Using sensitive ground microphones and amplifiers, we listen through the slab and follow the sound to its loudest point, which is usually directly above the leak.
Electronic line tracing and thermal imaging
We trace the path of the pipes so we know exactly where the lines run under your floor. On hot-water-line leaks, thermal imaging adds another confirmation by showing the warm trail the escaping water leaves across the slab.
Video pipe inspection
Where access allows, a small waterproof camera sent into the line lets us see corrosion, breaks and problem joints directly. It is especially useful for confirming the condition of older copper and deciding whether a spot repair or a reroute is the smarter fix.
Non-invasive by design
The entire point of professional detection is to avoid breaking concrete you do not have to. By pinpointing the leak to a small area, we protect your flooring, keep the job cleaner, and keep the cost down. If a repair does require opening the slab, it is the smallest opening possible. In many cases we can also recommend a trenchless reroute that avoids the slab altogether.
When you need slab leak detection
Call for detection when you notice the classic warning signs of a hidden leak:
- A warm spot on the floor, which often points to a hot-water-line leak.
- An unexplained jump in your water bill with no change in usage.
- The sound of running water when every fixture is turned off.
- A drop in water pressure throughout the home.
- Cracked, damp or warped flooring, or a musty smell.
- A water meter that keeps moving after you shut everything off.
If you see any of these, read more about the signs of a slab leak and call us. The sooner the leak is found, the less damage it does to your floors, slab and foundation.
Detection leads straight into repair
Detection is not a standalone report you have to act on alone. The moment we confirm and locate the leak, we walk you through the repair options that fit your pipe and your home, from a simple spot repair to a reroute, epoxy lining or a full repipe, with a written estimate before any work begins. See how detection fits into the overall cost of a slab leak repair.
Local detection you can count on
Many Prescott homes are built on slab foundations with aging copper supply lines, and the area's hard water speeds up the corrosion that causes pinhole leaks. That local experience matters: we know where these leaks tend to show up and how to find them fast. We serve Downtown Prescott, Yavapai Hills, Prescott Lakes, Hassayampa, Williamson Valley, the Granite Dells and the surrounding communities across ZIP codes 86301 through 86305 and 86313.
