Excavation & Underground Utilities in Harmony, NJ
JWSR LLC is a local, licensed and insured excavation and utility contractor working in Harmony and across Warren County. Harmony sits about 40 miles southwest of our Hamburg yard, roughly 60 minutes out, so we can get a crew and the right machine there without a long wait.
A lot of our work in Harmony is clearing and reclaiming land
Harmony is farm and open country, and plenty of land here has sat overgrown and unused for years. A good part of what we do here is land clearing, taking those lots back and turning them into something useful again, whether that is reclaiming a field for hay, opening ground for livestock to graze, or clearing a pad for a new building.
We clear, grub, grade, and haul so owners can put land that sat idle back to work. That is a big part of what we do here, but it is far from the only thing. We still handle sewer and water lines, septic, grading, driveways, and emergency digs across town.
Helpful guides: Storm damage: document before you clean up · Preventing erosion after excavation
Warren County is farm country and river valley, with long rural driveways, big lots, and a lot of grading and drainage work. Properties out here usually need real earthmoving, not just a quick patch.
As a township, Harmony has the kind of larger properties where septic systems, grading, drainage, land clearing, and long driveways come up most. Whether it is an emergency sewer or water line dig-out, a septic system, a lot that will not drain, or a new driveway, we bring our own equipment and an operator who knows the ground in this part of Warren County. We show up when we say we will, and we leave your property graded and clean.
