WHAT TO LOOK FOR
Signs You May Have a Slab Leak
- An unexplained spike in your water bill with no obvious cause
- You hear running water when every fixture is off
- You feel a warm or damp spot on your floor
- Surfaces grow mold, mildew, or a musty smell with no visible source
- Floors or walls have cracks that seem to be spreading
- Water pressure is low throughout the house
Orange County, in particular, suffers from expansive, shifting soil and aging slab-on-grade constructions that rely on copper pipes run directly through or under the slab. These factors can make OC homes more at risk of slab leaks than homes in other areas.
THE SLAB LEAK DETECTION PROCESS
How We Detect a Slab Leak
A slab leak is one of the few plumbing problems you usually can’t see, so finding it is most of the job. We start simple and only bring in more advanced tools when the situation actually calls for them, so we keep your slab (and your bill) intact.
- Water meter test — This is the first thing we check, and you can even do a rough version yourself before calling: Shut off every fixture in the house, then watch your water meter. If it’s still moving, water is going somewhere. It won’t tell us where, but it confirms there’s a leak worth tracking down.
- Pressure testing — Once we know there’s a leak, we isolate sections of your plumbing system, one at a time, to narrow down which line it’s on.
- Acoustic/electronic leak detection — Water escaping under pressure makes a sound. It’s a faint sound, but our equipment is built to pick it up through concrete and flooring. We’ve already found the line — this is how we find the actual spot to dig without opening up your entire slab.
- Thermal imaging — When a hot water line is the likely culprit, thermal imaging can show a temperature difference in the slab that lines up with everything else we’ve found. It’s not our first move, but it is a confirmation tool.
An unaddressed slab leak doesn’t just waste water; it can affect soil stability and, over time, the slab itself. That’s why a slab leak isn’t a “wait and see” repair.
Our Slab Leak Detection & Repair Services
Slab leak services aren’t one-size-fits-all. Whether you need a spot repair or a whole-home repiping, we can help.
Slab Leak Detection
Before we touch anything, we find out exactly where the problem is. Using listening equipment, pressure testing, or thermal imaging, we pinpoint the leak’s location without unnecessarily cutting into the slab. You’ll know what we found and why before we talk about next steps.
Spot Repair
When the leak is isolated and the rest of your plumbing is in good shape, we access the section of pipe directly and repair it. It’s the least invasive option, which usually means it’s the most affordable, too.
Pipe Rerouting
Sometimes the smarter move isn’t repairing the pipe where it is, it’s rerouting it through a wall or attic space and bypassing the damaged section completely. This comes up when the leak is in a hard-to-access spot, or when the existing line is old and ready to be replaced.
Whole-Home Repiping
If pressure testing reveals more than one weak spot, patching each leak as it happens doesn’t solve anything; it just delays the next call. If that’s what we find, we’ll tell you and walk you through whole-house repiping as the more permanent fix. We don’t push it if you don’t need it, but we won’t pretend you don’t need it, either.

Frequently Asked Questions About Slab Leak Detection & Repair
Common signs include unexplained spikes in your water bill, warm or wet spots on your floors, low water pressure, and the sound of running water when nothing’s turned on. If you see cracks forming in your walls or flooring without a reason behind them, that’s another serious red flag. We use electronic leak detection and thermal imaging to pinpoint problems quickly and without unnecessary excavation.
Today’s tools, like electronic listening equipment and pressure testing, are non-invasive, so there’s no need to tear up your entire floor. We pressurize the lines to isolate which pipe is losing pressure, then use audio or heat sensors to find the exact source. With this method, you get a clear picture of what’s wrong and a repair plan before any work begins.
Homeowners insurance typically does not cover slab leaks if they’re caused by age or poor maintenance. In California, homes often experience settling and earthquakes. If an earthquake causes a slab leak, it usually won’t be covered unless you’ve purchased separate earthquake insurance.
