Excavation & Underground Utilities in Greenwich, NJ
JWSR LLC is a local, licensed and insured excavation and utility contractor working in Greenwich and across Warren County. Greenwich sits about 43 miles southwest of our Hamburg yard, roughly 65 minutes out, so we can get a crew and the right machine there without a long wait.
In Greenwich, a lot of our work is drainage and grading
Greenwich has stretches of low ground and a high water table, so drainage problems and seasonal flooding come up again and again here. That is why a good chunk of what we do here is drainage and grading.
When a yard will not drain, a basement keeps taking water, or a lot floods every spring, that is our wheelhouse: French drains, regrading, swales, and moving water away from the house for good. 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.

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, Greenwich 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.
