Traditional Trench Sewer Line Replacement in Hilton Head Island
For major damage or certain pipe layouts, traditional trenching may be the most effective method. This involves digging a trench to access and replace the damaged sewer line directly. Our team plans the excavation to minimize disruption to your landscape, using the right equipment for efficient, precise digging. We make sure of proper grading and backfilling to prevent future issues and restore your property.
Cast Iron Sewer Replacement in Hilton Head Island
Cast iron drains in older homes corrode from the inside, particularly along the bottom of the pipe. Over time this leaves cracks, holes and a rough surface that snags waste. Replacing the cast iron sewer outside the home is often the first step. We can also evaluate under-slab cast iron and discuss lining or rerouting choices. New PVC or HDPE will not rust or scale the same way.
Sewer Line Material Upgrades in Hilton Head Island
Many older homes in Hilton Head Island still have sewer lines made from outdated materials like clay or cast iron, which are prone to cracking, corrosion, and root invasion. We offer upgrades to newer, more durable materials such as PVC or HDPE (high-density polyethylene). These materials stand up to corrosion, roots, and shifting soil, giving your sewer system a much longer lifespan.
Sewer Pipe Lining as an Alternative in Hilton Head Island
Cured-in-place pipe lining creates a new pipe inside the old one. After cleaning, a resin-soaked liner is pulled in and cured in place. This works when the host pipe still holds its shape without major sags or collapse. Lining can be a smart option under slabs or finished areas. We tell you plainly if your line is a candidate.
Open-Trench Sewer Replacement in Hilton Head Island, SC
Traditional excavation is sometimes the best option, especially when the old line has a severe belly or the slope must be corrected. We dig along the line, remove the old pipe and set new PVC on compacted bedding at the correct grade. Rocky or hard-packed soil can slow digging, and we account for that in the estimate. Each joint is glued and checked before backfill. The inspector sees the open trench before we close it up.
Residential Sewer Line Services in Hilton Head Island, SC
KBN Plumbing focuses on residential sewer line replacement for Hilton Head Island, SC homeowners. Clay that swells when wet and shrinks in dry spells can shift buried sewer lines over time, leading to sags, separated joints and root intrusion. We address the issues we see most, such as tree root intrusion, shifting ground, and aging cast iron or clay pipes. Our work keep your home's plumbing system working properly, protecting your property from sewage backups and possible foundation damage.

Trenchless Sewer Line Repair and Replacement in Hilton Head Island, SC
Trenchless technology, such as pipe bursting or pipe lining, offers a less invasive option to traditional methods. Pipe bursting pulls a new pipe through the old one, fracturing the old pipe in place. Pipe lining inserts a new, durable resin liner inside the existing pipe. Both methods significantly reduce the need for excavation, preserving your yard and landscaping in Hilton Head Island, SC while providing a long-lasting solution.

A pipe burst at 11 pm and they actually answered. The plumber showed up within the hour, shut everything down, and had us back to normal the next morning. Could not ask for more.
