Cranbury, Middlesex County
Excavation & Site Work in Cranbury, NJ
Princeton Excavation treats Cranbury the way a National Register village deserves to be treated — careful digs beside old foundations in town, and honest septic, clearing, and grading work on the farmland-edge lots around it.
Cranbury is really two kinds of property. Inside the village, Main Street and the blocks around Brainerd Lake are one of the best-preserved 19th-century streetscapes in New Jersey — old houses on deep, narrow lots with mature trees and not much room to maneuver. Outside it, the township has permanently preserved more than 2,000 acres of farmland, and the homes out there sit on big lots along roads like Plainsboro Road and Cranbury Neck Road, most of them on septic and well.
Those two settings ask for opposite things from an excavator. In the village, the job is precision: a footing beside a rubble foundation, a drainage line threaded past tree roots, a machine small enough to come down the driveway without touching anything. On the farm-edge lots, it's capacity: test pits for a septic replacement, brush and stump clearing, grading that moves real yardage.
We're set up for both, and every job is owner-operated — the person who prices the work is the person on the machine.

A historic village with farmland at its back
Village work near Main Street means working around what makes Cranbury Cranbury: old street trees, slate and brick walks, and houses that have stood since before excavators existed. We bring the smallest machine that can do the job — often the 2.5–3 ton mini excavator — plan the route in, and keep spoils contained so the property reads exactly as it did, minus the problem you hired us to fix.
Out along Cranbury Neck Road, Old Trenton Road, and the preserved-farm edges, properties run bigger and rely on their own systems. Septic replacements start with test pits dug clean for the engineer's soil logs, and failing drainage matters more here because a saturated yard shortens the life of a leach field. That's steady work for us in Cranbury, along with clearing overgrown corners and regrading around outbuildings.

Cranbury: Common Questions
Yes. Cranbury's village lots are deep but narrow, and access is usually a single driveway shared with the house. We size the machine to the driveway — often the mini excavator or the tracked mini skid steer, which fits about a 36-inch opening — and lay ground protection along the route in.
Yes. Most properties outside the village are on septic, and a replacement starts with test pits so the engineer can log the soils. We dig them clean and to depth, backfill when the engineer is done, and can handle the excavation side of the installation as well.
