Foundation holes, garage pads, additions, utility trenches, final grade — the dirt work that turns a Sanbornton lot into a build site, done on schedule so your contractor isn’t waiting.
Sanbornton’s gravel roads and long climbing driveways are the town’s signature, and they teach a clear lesson: on a grade, water is the enemy and geometry is the defense. We rebuild washed-out Sanbornton drives every year, and the fix is always the same fundamentals done properly — crown the surface so water sheds sideways instead of running down the wheel tracks, ditch the uphill side, and put culverts where the water wants to cross rather than where it’s convenient to dig. Spring is dramatic here; snowmelt off the hilltop fields moves serious volume, and several town roads post for mud season, which shapes our hauling calendar. Homesite work runs to hilltop clearings with long views, glacial till with scattered boulders, and springs that appear exactly where you planned the lawn. Around Hermit Lake and the Winnisquam shore, standard shoreland setbacks and permit rules join the checklist.
If your Sanbornton driveway washes out every spring, stop re-graveling the symptom. One properly placed 15-inch culvert with a stone apron, plus a re-crowned surface, usually ends the cycle for a decade. The gravel was never the problem — the water’s path was — and rerouting it costs less than three years of patching.
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.
