Who we are

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.

What we do

Our work breaks into three connected service areas.

Septic systems

  1. Septic system installation for new builds and full replacements
  2. Septic repairs for failed components, leaks, and drainfield issues
  3. Septic engineering and design, including soil testing coordination, permit drawings, and NJDEP-compliant system specs
  4. Singulair Green advanced treatment systems for properties where a conventional system does not fit the site
  5. Septic water jetting to clear blocked lines and restore flow
  6. Excavation and site work
  7. Site excavation for foundations, additions, and full site preparation
  8. Drainage installation for yard, foundation, and runoff problems common to Sussex County terrain
  9. Driveway installation, including grading, base, and finish work
  10. Retaining walls for grade changes and erosion control
  11. Land clearing for buildable lots and lot expansion

Sewer service

  1. Sewer line work, including camera inspection for residential and commercial properties

Why septic and excavation under one roof matters in Sussex County

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.

How we work — start to finish

  1. Free site evaluation. Mike or a senior team member walks the property, looks at the existing system or the proposed site, and identifies what is actually needed.
  2. Engineering and design. For installations and replacements, we coordinate soil testing, prepare engineered drawings, and pull NJDEP and county permits.
  3. Free flat-rate estimate. You get an upfront price before work begins. No hourly surprises.
  4. Installation or repair. Our own crew and equipment perform the work, including excavation, sand layering, and grading.
  5. Final grade and cleanup. The property leaves looking finished, not torn up.

Credentials, compliance, and how we handle money

  1. Licensed and insured in the State of New Jersey (specific license and registration numbers, including NJ Septic Installer License, NJ Home Improvement Contractor registration, and applicable NJDEP credentials, available on request)
  2. NJDEP-compliant work across installation, replacement, and design
  3. Free flat-rate estimates so the price you see is the price you pay
  4. Upfront, competitive pricing with no hidden line items
  5. 203K loan compatible for FHA renovation financing on home purchases
  6. Pay-at-closing arrangements available when a failing septic system needs to be fixed before a property sale can close
  7. 4.9 star customer rating across published reviews
