Newmarket’s downtown along Main Street has undergone a genuine revitalization, with former mill buildings converted to mixed-use space and new construction filling gaps along the Lamprey River waterfront. Excavation in the downtown core means working around old mill foundations—granite blocks, brick footings, and abandoned utility runs that predate modern mapping. The alluvial soil near the river is silty and wet, requiring dewatering and careful shoring on below-grade projects. Our CAT 313GC fits the constrained lot access typical of Main Street sites.

Away from downtown, Newmarket’s residential development extends along Route 108 toward Durham and along Route 152 toward Epping. These areas feature newer subdivisions on wooded lots where the soil transitions from river clay to well-drained sandy till—a shift that happens within a mile of the town center. Foundation excavation, septic installation, and driveway grading are the standard residential scope, with lot clearing often needed on the more heavily wooded parcels along Ash Swamp Road and Grant Road.

UNH’s proximity in nearby Durham adds a rental housing dimension to Newmarket’s construction market. Investors developing or renovating multifamily properties near downtown need excavation for utility upgrades, parking area construction, and foundation work. Rockingham County permitting applies to Newmarket projects, and the town’s building department has been active as the development pace has accelerated. The excavator rental demand here peaks from April through November but rarely stops entirely through the winter.
