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. Surprise has a wide range of housing ages, and while newer construction is less prone to it, hard water and soil movement can still cause slab leaks even in homes built in the last decade or two.
Left undetected, a slab leak can cause serious structural damage and mold. 100% Plumbing has handled slab leaks across Surprise 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 regardless of a home’s age. If you’re seeing any of the warning signs above, don’t wait — slab leaks get more expensive the longer they go undetected.
We’ve repaired slab leaks throughout Surprise, from Marley Park to the communities along Grand Avenue. 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.
Detection typically takes 1–2 hours. A direct repair through the slab can be done in a day, while rerouting may take 1–2 days. We’ll give you a specific timeline before we start.
