Excavating New Jersey LLC is a Wantage-based contractor operating throughout Sussex County and parts of Morris County. The business is owned and run by Mike [LastName], who oversees septic and excavation work directly, from initial site evaluation through final grading.
We are one of the few contractors in Northern New Jersey that handles both septic and excavation in-house, end to end. Most septic companies in the region subcontract excavation. Most excavators subcontract septic. We do both, with our own crews and our own equipment.
For homeowners, that means one company, one quote, one schedule, and one point of accountability on jobs that usually require two trades stitched together.
Our work breaks into three connected service areas.
Septic systems
Sewer service
A septic project in Sussex County is rarely just a septic project. The region sits on shallow bedrock, glacial till, and pockets of clay-heavy soil, and the topography runs steep and rocky in towns like Vernon, Hopatcong, and Wantage. We've written about how this geology works against septic systems and when trenchless methods do not work on steep, rocky terrain.
The practical result: most installations and replacements here require real excavation work. Cutting through bedrock, regrading slopes, building up sand layers, managing surface drainage, and reshaping the site so the new system performs for decades. When the septic installer and the excavator are two separate companies, that handoff is where projects stall, costs creep, and accountability gets blurry.
By handling both in-house, we control the timeline, the equipment scheduling, the soil management, and the final grade. The septic system gets installed by the same team that shaped the ground it sits in.
