Slab Leak Detection and Repair in O'Fallon
Slab leaks are common in homes built on concrete foundations, often caused by shifting soil or corroded pipes underneath. Our technicians use low-impact methods like electronic leak detection and hydrostatic pressure testing to find these hidden leaks.

We work with many pipe materials, including copper, PEX, and PVC, providing a durable repair for your O'Fallon property.
Slab Leak Detection & Repair in O'Fallon
Slab leaks are notorious for being difficult to detect, often showing quiet signs like warm spots on the floor or a sudden jump in your water bill.

Once identified, we offer fitting repair solutions, whether it's a spot repair, re-routing, or pipe bursting, to restore your plumbing system in O'Fallon without extensive damage to your property.
Copper Pipe Leak Repair in O'Fallon, MO
Many older homes in O'Fallon, MO have copper water lines beneath their foundations, which can corrode over time due to soil conditions or water chemistry. Water in much of Missouri is moderately hard to hard, so scale gradually builds in water heaters, faucets and fixtures. When these copper pipes develop pinhole leaks or cracks, they need specialized repair. Our technicians fix or replace sections of damaged copper piping, providing a durable seal that withstands pressure and ground movement and helps prevent future leaks.

Tunneling for Foundation Leaks in O'Fallon, MO
In some cases, the most effective way to repair a foundation leak is by tunneling beneath the slab.
