Foundation Leak Repair in Phoenix, AZ
The pipes that run under your home’s concrete foundation (often called a slab) are critical. When these pipes leak, it’s known as a slab leak, and it can undermine your foundation, cause severe water damage, and lead to mold growth. We specialize in the complex, careful work of foundation leak repair in Phoenix, using non-invasive techniques to locate the breach and the least disruptive methods possible to perform the necessary repair or reroute.
Leaks Under the Concrete Slab
Slab leaks are serious because they are hidden, and the escaping water can cause significant damage to the structural stability of your home. Causes typically include:
- Corrosion: Older copper pipes deteriorating over time due to mineral content in the soil.
- Shifting: Ground movement or settling that stresses and cracks the piping.
- Friction: Pipes rubbing against the concrete or rebar due to thermal expansion.
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.

Signs of a Foundation Plumbing Leak
Foundation leaks give off tell-tale warning signs that you should never ignore:
Hot Spots on the Floor: Indicates a leak in a hot water line beneath the slab.
The Sound of Running Water: When all faucets and appliances are off.
Cracks in the Foundation/Walls: Structural damage caused by expanding soil or erosion.
Unexplained Water Bills: A drastic and sudden spike in your monthly statement.
Expert Slab Leak Repair Methods
After using acoustic or thermal detection to pinpoint the exact leak location, we recommend the most practical and least destructive repair method:
- Spot Repair: Carefully breaking the slab open only at the leak location to fix the pipe section.
- Rerouting: Bypassing the faulty underground line by running a new line through the attic or walls.
