Dependable Excavation Plus

Dependable Excavation Plus is a locally owned, Washington State licensed excavation contractor based in Centralia, serving Lewis County and the surrounding South Sound. Owner-operator Sean Teeter has been digging, grading and building sites here since 2021 — new construction excavation, septic systems, driveways, land clearing, drainage and finish grading, handled start to finish by the same crew that shows up on day one.

"Dig holes and complete goals." It is a simple promise: show up when we say we will, work clean, and leave the property better than we found it.
