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.  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.
