Water Line Reroute in Charleston
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 typically use PEX for reroutes because it is flexible and resists corrosion. Drywall openings are kept small and neat for simple patching.
Tunneling for Foundation Leaks in Charleston, SC
In some cases, the most effective way to repair a foundation leak is by tunneling beneath the slab. This method allows our plumbers to reach the damaged pipe directly without breaking through your home's interior flooring. KBN Plumbing is experienced in safe and efficient tunneling, minimizing disruption to your Charleston, SC home and ensuring a complete repair of the damaged pipe section.

Crawl Space Foundation Leak Repair in Charleston, SC
Crawl space foundations can develop leaks from plumbing, groundwater, or HVAC condensation. These leaks can lead to wood rot, mold, and structural damage if not addressed quickly. Our team thoroughly 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 Charleston, SC from future moisture issues.

Post-Tension Slab Leak Repair in Charleston
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.
