Centerline is a family owned business. We have been locating underground lines since 1989. Centerline started out as a part-time endeavor. With the word getting out, we quickly became a full-time business, securing contracts with utilities to represent them to perform dig safe requests. These recommendations come from our attention to detail. We put all the “pieces of the puzzle” together to make sense of the located job sites.We recently added more employees and opened an office in southern Maine to allow us to cover the whole State of Maine. We also will perform work in NH, MA and Vermont.
