A small crew that treats your ground like its own
Bellingham Septic Co. is a small, owner-operated septic outfit based in Bellingham and working across Whatcom and Skagit counties. When you reach out, you hear from the person who will actually be on your site. There is no sales layer between you and the work.
We keep the operation deliberately small: compact excavators, tight crews, and jobs we can stand behind. That is a choice, not a limitation. Small machines get into treed, sloped lots without wrecking them, and a small crew means the person who quoted your job is the one building it.
Our approach shows in the photos across this site: tidy trenches with clean sidewalls, laser-shot grades, risers stacked to finished grade, and drainfields laid out with care before the first bucket goes in.
Bellingham Septic Co. operates alongside Bellingham Excavation Co. under Strong Construction. If your project involves clearing, grading or drainage as well as a septic system, one contractor covers both sides of the work.
