Underground utilities, excavation, and sewer & water lines, done right.

JWSR LLC is a licensed and insured utility construction and excavation contractor in northern New Jersey. Our main work is underground utility construction and repair: water lines, sewer lines, service laterals, and storm drainage, plus excavation, septic, grading and drainage, driveways, road repair, parking lots, retaining walls, hardscaping, and land clearing.

For everyday residential and commercial work, JWSR serves northern and central New Jersey, from Montague in the north down to Hillsborough and Montgomery in the south, west to Alpha, and east through Bergen County. That covers Sussex, Warren, Morris, Hunterdon, Somerset, Passaic, and Bergen counties, based at 17 Prince Street, Hamburg, NJ. And we travel: JWSR holds active contracts in seven states, New Jersey, New York, Pennsylvania, Connecticut, Delaware, Virginia, and West Virginia, and we go where the work is, whatever the trade.

No. On-site estimates are free. We come look at the job, tell you straight what it needs, and give you a fair, upfront price. The one exception is design work: if your project needs drawings, mockups, or a site plan, we charge a consultation fee for that time, and if you hire us for the project, that fee comes right off your total. It keeps our design work with the people who actually want us to build it.
