Cast Iron Sewer Replacement in Bellingham
Cast iron drains in older homes corrode from the inside, especially 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.

Traditional Trench Sewer Line Replacement in Bellingham
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 carefully 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.
Trenchless Sewer Line Replacement in Bellingham, WA
To minimize disruption, trenchless sewer line replacement replaces pipes without extensive digging. We offer pipe bursting, where a new pipe is pulled through the old one, fracturing the old pipe outward. This is ideal when protecting landscaping or driveways is a priority. The method works well for many homes in Bellingham and can often be completed faster than traditional methods, using high-density polyethylene (HDPE) pipe known for its long life.

Sewer line replacement is a significant project that requires following local plumbing codes and often needs permits from Bellingham authorities.
