Cornerstone Professional Land Surveying, Inc. has provided a comprehensive package of land surveying services throughout the State of Maine for over 27 years. Since its founding in 1989 our company has served over 600 clients, ranging from individual landowners to government agencies. Much of this business has come from word of mouth referral. From one client to another we have established a solid reputation as an honest, thorough, and hard working company.

Cornerstone is solely a land-surveying firm, and does not compete with other professional services such as engineering, soil evaluation, and architectural firms. This allows us to promote a team spirit with these professionals to provide you the quality of service your project deserves. Whether we’re spearheading your project, a member of a team, or the sole professional you hire, our mission is always to provide superior services for our clients.
