Slab Leak Detection & Repair

Slab Leak Detection & Repair in Glendale, AZ

We find slab leaks fast and repair them with as little disruption to your home as possible — and we’re based right here in Glendale.

A slab leak is a leak in the water lines that run beneath your home’s concrete foundation. In Glendale, we see this most in the older, established neighborhoods near the city center, where original copper supply lines have had decades to corrode. Left undetected, a slab leak can cause serious structural damage and mold.

100% Plumbing’s office is in Glendale, and we’ve handled hundreds of slab leaks across the city and the greater Northwest Valley.

What’s Included

What We Do

Watch For This

Signs You Need This Service

Glendale’s older housing stock, especially homes built before the 1990s, still runs original copper supply lines. Combined with Arizona’s hard water and the soil movement common in the Valley, those lines take extra stress underground. If you’re seeing any of the warning signs above, don’t wait — slab leaks get more expensive the longer they go undetected.

Why 100% Plumbing

Why Glendale Homeowners Call Us

Our office is in Glendale, so when you call about a suspected slab leak, we’re not driving in from across the Valley. We locate the leak precisely before recommending any repair option, and we walk you through every option — including rerouting, which avoids breaking your slab entirely — before any work begins.

Common Questions

Straight Answers, No Runaround

How do you find a slab leak without tearing up my floor?

We use electronic leak detection equipment that listens for the sound of water escaping the pipe and pinpoints the location from above. In most cases we can locate the leak without any demolition at all.

Do you have to break up my foundation to fix it?

Not always. Depending on the location and severity, rerouting the pipe through the walls is often a better option than breaking through the slab. We’ll explain both options and the pros and cons of each.

How quickly can you get to a Glendale home?

Since our office is in Glendale, we can usually get someone out the same day for a suspected slab leak.
