Leak Detection Services in Phoenix, AZ
Hidden leaks—the ones behind a wall, under a cabinet, or beneath your foundation—can go unnoticed for months, slowly causing devastating water damage and mold growth. As your trusted Phoenix plumbers, we provide comprehensive leak detection services for all parts of your plumbing system. We use advanced technology to pinpoint the source of the leak accurately, allowing for targeted, minimally invasive repair.
Why You Need Leak Detection
If you see a sudden spike in your water bill or hear the faint sound of running water, you have a leak. Relying on guesswork and tearing up walls and floors to find the problem is costly and destructive. Professional leak detection ensures:
- Accuracy: We find the exact location of the pipe breach.
- Minimal Destruction: Repair requires minimal removal of drywall or concrete.
- Speed: We find the leak faster, reducing water waste and damage time.
Leaks We Find and Fix
Not every leak is obvious. A high water bill, warm floor, or musty smell is often the first sign — we use professional detection equipment to find the source without tearing up your home.
Slab Leaks
Pinhole leaks under the foundation are a Phoenix specialty. We locate them with electronic detection and repair, re-route, or repipe based on your line condition.
Hidden Wall and Ceiling Leaks
Soft drywall, paint bubbles, and water stains all point to a leak you can't see. We find it without unnecessary demolition.
Outdoor and Irrigation Leaks
Soggy patches, unexplained water bills, and pressure drops in the yard. We trace the line and repair the break.
Pinhole Copper Leaks
Hard water and Phoenix soil chemistry chew through copper. We patch the immediate leak and tell you honestly whether it's a one-off or a repipe conversation.
Toilet, Faucet, and Fixture Leaks
The leaks that drive your water bill up without making a sound. We test every fixture and shut-off in the home if you'd like.
Mainline and Water Meter Leaks
Between the meter and your home is your responsibility. We locate the leak, get the right easement clearances, and repair or replace the line.
No matter your industry, our commercial plumbers provide service you can rely on.
Advanced Technology for Leaks
We invest in the best diagnostic equipment to service your home efficiently. Our leak detection tools are non-destructive and highly effective:
Sensitive Listening Equipment: To locate the subtle sound of water escaping a pressurized pipe.
Non-Invasive Meters: To measure moisture behind walls and in flooring to track the water path.
Pressurization Testing: To confirm a pipe is leaking and to isolate the specific line affected.

Precise Leak Mapping and Finding
Once we confirm a leak exists, we create a precise map of the leak’s location, whether it’s 10 feet into the main line or 3 feet under the slab. This transparency is our promise to you: we will find your leak, and we will do it in a way that protects your property from unnecessary damage.
