Company Profile

David O'Neil Construction, LLC is a fully licensed and insured excavation company serving the south western region of New Hampshire. Established in the early 90's, David has the know how when it comes to your project. With over 20 years experience in the excavation field and 18 years prior in the carpentry and building trades, you are guaranteed to be satisfied.

David started his business building new homes, additions, renovations, kitchens, bathrooms and more. Eventually realizing that is was always hard to get the excavation under way, David decided to begin doing excavation himself. David started out with a small 6 wheeler dump truck and a backhoe. He has worked hard to build his company to the size it is today. Today, the fleet includes: two Link-Belt Excavators, a Kubota Mini Excavator, two Mack dump trucks, a John Deere Backhoe, a Skid Steer, three company job trucks and more.

We are now located on Route 101 in Marlborough, New Hampshire and we encourage customers (past, present and future) to stop in.
