Zachau Construction is one of Southern Maine’s leading commercial construction management companies, working with the state’s most recognized corporations, institutions, and non-profits. Our dedication to maintaining honest relationships and partnerships, above all else, has carried us from our founding in 1969, by Earle Zachau, to where we are today. 

Now 100% employee-owned, we’re more invested than ever—each project reflects our shared pride, purpose, and commitment to doing great work. As a third-generation company, we remain rooted in our values while evolving to meet the future together.
