About Us

Trevor Mohney Excavating started the way a lot of good local outfits do, with one guy, one machine, and a reputation to earn. Today we’re a family-run septic and excavation company based in Washington, PA, but not much has changed about how we treat people. We still answer our own phone, we still show up when we say we will, and we still take pride in leaving a job better than we found it.

Septic work is the heart of what we do. New systems, repairs, replacements, drain fields, you name it. And because we own and run our own excavation equipment, we handle every part of the job ourselves instead of handing it off. That means one crew, one point of contact, and no fingers getting pointed when something needs sorting out.

Most of our work comes from word of mouth, neighbors telling neighbors, and that’s exactly how we like it. When your name is on the truck, you do the job right.
