Expert Septic System Installation in Sussex County, NJ

Precision Earthworks provides septic system installation for residential and rural properties throughout Sussex County. Many homes here rely on private septic because public sewer access is limited across the county's rural townships. Sussex County properties often present real site challenges: heavy glacial till, dense clay layers, high seasonal water tables, and shallow ledge rock. These conditions affect what system type your lot can support. Our process starts with a soil and site evaluation, including percolation testing, to read your property before any design work begins. From there, we build a system sized to your home's bedroom count and actual water use. Properties in the Highlands Region, which covers much of Sussex County, may also require additional environmental review under the Highlands Water Protection and Planning Act. We coordinate that process so nothing falls through. Whether your lot calls for a conventional in-ground system or an engineered mound system, Precision Earthworks handles the installation from excavation through final grading. Call us to schedule your site evaluation.

Precision Earthworks LLC did an amazing job clearing and regrading my backyard (about ½ acre). Matt and his crew were professional, hardworking, and communicated extremely well from scheduling through completion. They worked two full days—nearly 10 hours each day—and the results speak for themselves. I couldn’t be happier and highly recommend them. A picture is worth a thousand words—see below!

Matt and his crew did an outstanding job with our land clearing project from start to finish. The crew was professional, punctual, and extremely hardworking. They cleared the property quickly while still paying attention to detail and leaving everything clean and properly graded when the job was complete. Communication was excellent throughout the entire process, and they made everything stress-free. It’s hard to find contractors who take this much pride in their work. I highly recommend Precision Earthworks LLC to anyone looking for reliable, high-quality excavation and land clearing services

What a pleasure it was to work with Matt and his crew from Precision Earthworks. Matt is a hardworking, honest, and reliable young man who clearly takes pride in what he does — and it shows in the quality of the work. His team did a fantastic job clearing a section of my property, and the entire process was smooth from start to finish. Communication was clear, concise, and always followed through with exactly what was promised. Throughout the job, Matt checked in multiple times to make sure everything they were doing met my expectations. That level of professionalism and respect for the homeowner is rare. On top of the excellent workmanship, Matt’s pricing is very reasonable — especially considering the quality, efficiency, and care he and his crew bring to the job. It’s obvious that the whole team takes great pride in their work, and the results speak for themselves. I couldn’t be happier with the job they did and highly recommend Precision Earthworks to anyone looking for land clearing done the right way.
