Excavation & Utility Contractor for Morris County, NJ
JWSR LLC is a licensed and insured excavation and underground utility contractor covering every municipality in Morris County, from our base in Hamburg, NJ. Morris County runs from busy suburban neighborhoods to wooded hillsides, and the work follows suit, from tight utility repairs to regrading sloped lots that will not drain.
From the Matrix Logistics Park corridor to rocky hillside lots
Morris County runs the full range for us. In the Mount Olive corridor, projects like the $93 million Matrix Logistics Park mean serious site work: pads, roads, utilities, and stormwater. In the wooded townships the Highlands bedrock brings ledge rock excavation, and in the established boroughs we replace a lot of aging driveways and retaining walls.

Morris County mixes dense boroughs with rocky wooded townships, and the jobs mix the same way. In the established neighborhoods we replace aging driveways, retaining walls, and drainage that went in decades ago. In the hill towns we fight the Highlands ledge rock that shows up a few feet down in almost every dig.
The Mount Olive corridor adds serious commercial site work, with projects like the Matrix Logistics Park driving demand for pads, utilities, and stormwater. We bring the same crew and standards to a backyard wall as we do to a commercial pad.
Who certifies your soil erosion plan here
Disturb more than 5,000 square feet in New Jersey and the work needs a soil erosion and sediment control plan certified by your county Soil Conservation District. Not the town, and not NJDEP. In Morris County that is the Morris Soil Conservation District.
Contact details from the NJ Department of Agriculture, New Jersey Soil Conservation Districts directory (April 2026). The district has 30 days to grant or deny certification. Full statewide list on our New Jersey Soil Conservation District directory.

Some of what we have been building
Working in Morris County
Do you really handle the rock in the hill towns?
Yes. Ledge is normal in the Highlands part of Morris County, and we carry the breakers and equipment to get through it without change-order drama.
Do you work in the denser boroughs with tight access?
All the time. Mini excavators and careful staging let us rebuild walls and driveways on tight lots without wrecking what is around them.
