We find slab leaks fast and repair them with as little disruption to your home as possible.
A slab leak is a leak in the water lines that run beneath your home’s concrete foundation. The Deer Valley and Happy Valley corridors, along with the neighborhoods bordering Peoria and Glendale, are part of our regular coverage — and slab leaks are a call we run there often.
Left undetected, a slab leak can cause serious structural damage and mold. 100% Plumbing has handled slab leaks throughout northwest Phoenix and the Northwest Valley.

Arizona’s hard water accelerates corrosion in copper pipes, and the soil movement common across the Valley puts extra stress on underground lines. If you’re seeing any of the warning signs above, don’t wait — slab leaks get more expensive the longer they go undetected.
We work this part of Phoenix regularly, so 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.
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.
Not always. 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.
Yes. That corridor, along with the neighborhoods bordering Peoria and Glendale, falls squarely in our regular service area.
