What We Do

Our Services

Site Work & Excavation

Full-service excavation — earthmoving, cuts and fills, and machine work to prep your lot for whatever comes next.

Land Clearing & Grubbing

Clearing brush, stumps and trees off raw lots, leaving a clean, workable site.

Grading & Drainage

Rough and finish grading plus drainage so water moves away from your foundation, not toward it.

Foundation Excavation

Precise digs for slabs, footings and full foundations, backfilled and compacted right.

Septic Systems

New septic system excavation and installation, sized and sited to NH code.

Gravel Driveways

Driveway cuts, base prep and gravel placement built to shed water and last through mud season.

How We Work

From walkthrough to finished grade

On-site walkthrough

We meet at your property, walk the site, and talk through access, grades, and where the water needs to go.
Clear, up-front quote

You get a detailed, fair quote before any machine shows up — no surprises once we start.
Clean, careful digging

We excavate and grade to spec and keep a tidy job site from the first cut to the last pass.
Walk it & sign off

We walk the finished grade with you and don't pull off the job until it's right.
