N.M. Curtis Earth Works INC is a site contracting company based out of Berwick, ME. With over 10 years of projects under our belt we are a Maine, and New Hampshire approved contractor. Curtis Earth Works is a small firm focusing on small to mid-size commercial site, and roadway projects but not limited to State and Federal projects as well. Bonding is available for projects with those requirements. Nick Curtis the owner/president, believes the key to setting ourselves apart from the competition is craftsmanship and attention to detail. That is why he works on every job site and works closely with the estimating staff to provide a top-quality service and a competitive, and accurate proposal.

In the field Curtis Earth Works utilizes many industry leading pieces of equipment such as GPS for layout and grade control. We believe this is key to ensure your project is completed accurately, on time, and on budget. We operate with a small crew size of 4-5 employees regularly on each site, we believe this is key to productivity. A small office staff is on duty to provide a quick turn-around for things as simple as a certificate of insurance to a bid proposal.
