Foundation holes, garage pads, additions, utility trenches, final grade — the dirt work that turns a Plymouth lot into a build site, done on schedule so your contractor isn’t waiting.
Plymouth sits on glacial outwash — deep sandy terraces laid down by the Baker and Pemigewasset — and that geology is a gift to excavators: fast digging, easy trenching, soils that drain almost too well. The flip side is the floodplain; both rivers claim real estate in a big spring, so we check flood zone lines early on any low-lying project and set grades accordingly. The rental economy around Plymouth State drives a steady, particular kind of work: gravel parking pads behind multi-unit houses, built with fabric under the base so four winters of plowing don’t churn them into mud, plus drainage fixes for backyards that six parked cars have compacted into ponds. Village lots are tight, with the usual old-town underground, so 811 marks come first. Summer is our Plymouth window for rental work — students gone, driveways empty, and eight clear weeks before the leases turn over in late August.
Building a parking pad for a Plymouth rental? Put geotextile fabric under the gravel — it’s a small line item that keeps the base from pumping down into the subsoil under daily traffic and plowing. A fabric-based pad is still a pad in ten years; a gravel-on-dirt pad is a mud problem by year three.
Every build starts and ends with dirt. We dig foundations and frost walls to spec (four-foot frost depth here isn’t a suggestion), cut and fill to bring a sloped lot to grade, trench for water, power, and septic lines, and come back at the end for the finish grade that sheds water away from the new foundation. On ledge-prone ground we dig test pits first — finding granite with a quote instead of a change order.
We coordinate directly with your builder, and we show up when the schedule says — because everyone downstream of the dirt is waiting on it.
Machine-and-operator excavation runs $110–$200/hour in the region; typical foundation digs land $3,000–$10,000 depending on size, soils, and ledge. Test pits and a site walk get you a flat number before we start.
Most Lakes Region foundation excavations run $3,000 to $10,000 — driven by size, soil, water table, and whether we hit ledge. Test pits before quoting mean the number you get is the number you pay.
It's common here. We dig test pits at the corners before quoting, so ledge shows up in the plan — hammering or blasting gets priced up front, not as a mid-job surprise. If ledge makes one corner of the lot expensive, sometimes shifting the footprint twenty feet saves five figures.
Prime season is May through November. Deep frost slows winter digging, and March–April mud season closes many posted town roads to loaded trucks. We schedule around both — and fall is the smart time to book a spring dig.
