Skilled Slab Leak Repair Services in Florissant, MO
FGV Plumbing finds and repairs leaks in water lines running beneath concrete slab floors. Hot water slab leaks are particularly common because heat, mineral content and expansion wear copper faster where it touches concrete and gravel. Water in much of Missouri is moderately hard to hard, so scale gradually builds in water heaters, faucets and fixtures. We find the leak, then repair it through the floor or reroute the line overhead.
Our expertise includes:
- Foundation-safe repair methods
- Acoustic and thermal pinpointing to limit concrete cutting
- Hot and cold line reroutes through attics in PEX-A

PEX Repiping for Slab Leaks in Florissant, MO
If multiple slab leaks point to a systemic issue with your home's original plumbing, a full PEX repipe might be the most cost-effective and durable solution. PEX tubing is flexible, corrosion-resistant, and less prone to leaks caused by foundation shifts, making it a good choice for many homes. We can replace all the water supply lines in your Florissant home, providing a brand-new, leak-free plumbing system that will last for decades.

Spot Repair Through the Slab in Florissant, MO
When the leak is isolated and the rest of the pipe is in good shape, a spot repair through the slab is a sensible option. We cut a small opening, excavate to the pipe and replace the damaged section. The trench is compacted and the concrete is patched. Flooring is then restored by your preferred contractor.
Direct Slab Leak Repair in Florissant, 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 careful concrete cutting and restoration, so the repair is effective and the area is professionally restored. We use durable materials designed to hold up to soil movement under the slab.
Slab Leak Repair Cost Comparison in Florissant, MO
Spot repairs usually have a lower upfront cost but involve breaking concrete and repairing flooring. Reroutes cost somewhat more but avoid concrete work and future leaks in that line. Whole-house repipes are the best choice when you have had multiple slab leaks or old copper throughout. We give you clear prices for each option.
Slab Leak Pipe Rerouting in Florissant
For more complex or recurring slab leaks, or when the original piping is severely 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 Florissant with aging copper or galvanized pipes.
Slab Leak Repair for PEX and Copper Lines in Florissant, MO
Whether your home in Florissant, MO has modern PEX piping or traditional copper lines, our plumbers are skilled 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.
Tunneling Slab Leak Repair in Florissant, MO
In some cases, especially when the leak is under a load-bearing wall or in a hard-to-reach area, tunneling beneath the foundation is the preferred method. This allows our plumbers to reach the damaged pipe from outside your home, avoiding disruption to your interior floors and finishes. Tunneling spares the interior but calls for skilled excavation and shoring to protect structural integrity throughout the repair process in Florissant, MO.
