Slab Leak Detection in St. Peters
We start by shutting off fixtures and watching the meter to verify a leak. Then we isolate the hot and cold lines to find out which one is leaking. Using acoustic ground microphones, we listen for the sound of escaping water through the concrete. Thermal imaging shows hot water leaks as warm areas on the floor surface.

Slab Leak Reroute in St. Peters
Rerouting is often the best long-term choice, especially with older copper lines. We abandon the leaking line under the slab and run a new PEX line through the attic and walls. Openings are small and placed where patching is easiest. Reroutes end future leaks in that section of pipe.
Slab Leak Pipe Rerouting in St. Peters
For more complex or recurring slab leaks, or when the original piping is badly deteriorated, pipe rerouting is an effective long-term solution. This method involves abandoning the leaky pipe under the slab and installing new plumbing lines through walls or the attic, bypassing the foundation entirely. This eliminates future slab leak risks from that particular line and is often preferred for older homes in St. Peters with aging copper or galvanized pipes.
Slab Leak Repair for PEX and Copper Lines in St. Peters, MO
Whether your home in St. Peters, MO has modern PEX piping or traditional copper lines, our plumbers are proficient in repairing both. Pinhole leaks are common in older copper due to corrosive soil conditions and water chemistry, while PEX can sometimes suffer from installation issues or rodent damage. We carry a full range of parts and tools for both materials, ensuring a correct and durable repair no matter your pipe type.
Advanced Leak Detection Technology in St. Peters
Our approach to effective slab leak repair includes investing in the latest diagnostic technology. We use equipment such as thermal imaging cameras to detect temperature changes caused by leaking hot water lines, and very sensitive acoustic sensors to listen for the sound of escaping water. This technology allows us to locate leaks without guesswork, even in the varied mix of buildings across St. Peters.
Pipe Rerouting and Repiping in St. Peters
For more extensive damage, multiple leaks, or pipes that are too old and corroded to repair reliably, pipe rerouting is a long-term solution. This involves abandoning the leaking line under the slab and installing a new pipe through the walls or attic. This method skips the problem area entirely, providing a fresh, durable plumbing line. It is a common solution for aging homes in St. Peters with original copper or galvanized plumbing.

Direct Slab Leak Repair in St. Peters, MO
When a slab leak is localized and accessible, direct repair is often the most efficient solution. This involves carefully jackhammering a small section of your foundation to expose the damaged pipe, then repairing or replacing the compromised section. Our technicians are skilled in precise concrete cutting and restoration, so the repair is effective and the area is properly restored. We use durable materials designed to hold up to soil movement under the slab.
