PEX and PVC Foundation Leak Repair in St. Charles
Newer homes often feature PEX or PVC plumbing, which, while durable, can still develop foundation leaks due to ground movement or poor installation.

We use proper fusion and solvent welding techniques to make strong, leak-proof connections, restoring the integrity of your plumbing system beneath your St. Charles foundation.
Post-Tension Slab Leak Repair in St. Charles
Many newer homes are built on post-tension slabs with steel cables under high tension. Cutting into these slabs takes care and scanning to avoid hitting a cable. We use ground-penetrating radar or other scanning methods before opening the floor. When the risk is too great, rerouting the plumbing is usually the safer option.

Crawl Space Foundation Leak Repair in St. Charles, MO
Crawl space foundations can suffer leaks from plumbing, groundwater, or HVAC condensation. These leaks can lead to wood rot, mold, and structural damage if not addressed quickly. Our team carefully inspects the crawl space and identifies the source of water intrusion. We then put in place solutions such as pipe repair, sump pump installation, or vapor barrier replacement to dry out and protect your crawl space in St. Charles, MO from future moisture issues.

Water Line Reroute in St. Charles
Rerouting abandons the leaking line under the foundation and runs a new line through the attic or walls. This skips breaking concrete and removes the risk of future leaks under the slab. We usually use PEX for reroutes because it is flexible and resists corrosion. Drywall openings are kept small and neat for simple patching.

Frequently Asked Questions About Foundation Leak Repair in St. Charles
Leak detection typically costs $150 to $450. Direct repairs through concrete usually range from $1,500 to $4,000, and reroutes often run $1,800 to $5,000 depending on length and access. Full repipes cost more and are quoted individually.
Yes. Our repairs come with a written workmanship warranty, and materials carry manufacturer warranties. We explain coverage before starting work.
Foundation leaks can be caused by many factors, including shifting soil that stresses pipes, corrosion of older copper lines from water or soil chemistry, poor pipe installation, and even extreme temperature swings. Limestone and rocky ground in the southern part of the state can make digging for sewer lines slower and more costly. Water in much of Missouri is moderately hard to hard, so scale gradually builds in water heaters, faucets and fixtures.
Depending on the leak's location, some foundation leak repairs may require digging or breaking concrete, particularly for slab leaks or exterior drainage issues. However, we always favor non-invasive detection methods and low-impact repair techniques whenever possible, such as trenchless pipe repair or targeted slab access.
Common signs of a foundation leak include sudden increases in water bills, wet spots on floors or walls, mildew odors, visible cracks in the foundation or interior walls, and standing water around the foundation perimeter. If you notice any of these, it is important to have your foundation inspected promptly.
Direct repair works well for a single leak in otherwise good pipe. Rerouting is often better when pipe is aging, the slab is post-tensioned or the leak is in a hard-to-reach spot. We help you weigh both.
FGV Plumbing stands behind the quality of our work. We offer a comprehensive warranty on all foundation leak repairs, covering both parts and labor. Specific warranty details will be provided with your estimate, giving you peace of mind for your St. Charles home.
Simple repairs often do not require a permit, but reroutes and repipes may, depending on your city. We pull permits when required.
