Princeton Excavation covers Pennington borough and the Hopewell Valley around it, pairing gate-width machines for the tight village blocks with real digging capacity for the valley's larger rural properties.
Pennington packs a lot of old housing into about a square mile. The blocks around Main Street, Delaware Avenue, and Curlis Avenue hold homes that go back a century or more, on lots where the side yard is the only way in and the neighbors are close enough to notice everything. Work here has to be compact, quiet about it, and clean.
Step past the Route 31 bypass and it flips. Out the Pennington-Titusville and Pennington-Lawrenceville Roads, the valley opens into acreage: wooded edges to push back, long gravel drives, and homes on well and septic that need test pits, tank access digs, or a cleared building spot.
One owner-operated outfit handles both because the fleet scales: a mini skid steer that fits a 36-inch gate for the borough, a 5-ton excavator and dump truck for the valley.

One square mile of borough, a valley of acreage
In the borough, most projects start with the same question: how do we get in? Detached garages off rear alleys, additions tucked behind 1900s homes, and fenced gardens mean we usually walk the property line before we quote anything. The machines we bring are chosen for those gaps, not squeezed into them.
Out in the surrounding Hopewell Valley, plenty of properties still run on well and septic, so we do a steady trade in excavator support for septic work: test pits and soil-log digs for the engineer, uncovering tanks and distribution boxes, and rough-grading the lawn back when the system work is done.

From the first call to a clean handover
Site Walk
We come look at the property by appointment, check the access and any constraints, and go over your plans or what you have in mind.
Marking & Layout
We set the layout on the ground with laser accuracy. Depths, lines, and elevations are marked before anything gets dug.
The Work
We bring the right machine for the access, lay ground protection where it's needed, and keep the mess around lawns, trees, and hardscape to a minimum.
Clean Handover
You're left with a site that's ready to go and a yard that's still in one piece, set up for whatever's next.
Pennington: Common Questions
Usually, yes. Our tracked mini skid steer is built for exactly this: it fits through roughly 36-inch openings, so standard gates and most borough side yards work. For excavation jobs we pair it with our smallest excavator where the gap allows. We measure the actual access on the site walk and pick machines to match.
Yes. For properties on septic around Pennington we dig test pits and soil profile pits at the locations your engineer or the health department marks, hold the hole open safely while they log it, and backfill and grade when they're done. We work at the engineer's direction; the design and approvals stay with them.
