What Is a Slab Leak?

A slab leak happens when a water line running under your home's concrete foundation begins to leak. These leaks are often caused by pipe corrosion, pressure issues, or natural wear over time. Because the leak is hidden under the slab, it can go unnoticed until serious damage starts to appear.
OX Plumbing specializes in locating and repairing slab leaks throughout Mesa, Chandler, Gilbert, Tempe, Queen Creek, and the entire East Valley. We use advanced detection equipment to find the exact source — and fix it the same day.
Signs You May Have a Slab Leak

Slab leaks are hidden under your foundation, so they often go undetected until visible damage appears. Watch for these warning signs:
- Unexplained increase in water bill
- Warm or damp spots on floors
- Cracks in walls or flooring
- Mold, moisture, or pooling around the home
- Sound of running water when everything is off
- Water meter moving with no fixtures running
Why Slab Leaks Are Serious

Slab leaks can cause structural damage, foundation issues, and major water damage if not handled quickly. Because they occur under the home, they require specialized equipment and expertise to locate and repair properly.
The longer a slab leak goes undetected, the worse the damage gets — and the more expensive it becomes to fix. Don't wait. If you suspect a slab leak, call OX Plumbing immediately.
What's at risk:
- Foundation cracks & shifting
