About Us

With over 20 years of building Maine’s commercial, institutional, and residential buildings, Warren Construction Group is a well-established premier builder. 

Peter Warren started Warren Construction Group in 1999 after decades in the building industry. Because Peter deeply cared about his employees, in 2016 WCG became an ESOP – a 100% employee-owned business. Sadly, Peter passed away in May of 2022, but because of his forward thinking WCG has been able to continue with the legacy of quality building that Peter began over 20 years ago.

We believe in the ESOP advantage. Being an ESOP gives every employee of WCG ownership and creates a culture of accountability. Because of this, we each have a heightened sense of commitment to the success of your project. This accountability keeps us empowered to problem solve, innovate, and engage in the work we do. We are consistently looking to improve and perform at our personal best, every day.

We not only build beautiful structures we also build long lasting relationships with clients, architects, subcontractors, and suppliers. It is our privilege to construct a wide variety of buildings throughout the state, from intricate custom homes to campus athletic centers and everything in between. During this process we develop strong relationships with those we work with, many of whom choose to collaborate with us again and again.

We believe straightforward, honest communication at every phase of the planning and building process is vital to a successful project. We approach every project with personal interest, pride, and transparency. This means ensuring clarity with regards to the financial expectations and building processes. We view every job as unique and use value engineering to achieve a balance between a client’s need for function, performance, quality, and cost.

We believe in innovation. While remaining rooted in foundational building principles, Warren Construction Group heartily embraces innovative technologies and techniques. We have proudly worked on LEEDS, Passive House and WELL projects.

We adhere to strict safety standards. We believe that a safe jobsite is paramount for the protection of our employees, our clients, and the surrounding community. Our Safety Director is charged with monitoring the active practice and development of our safety policies. As a result, we have received over a dozen awards for our outstanding safety record, including the Richard J. Haines Memorial Award for Safety Excellence in 2009 and 2022.

We stand behind our work. At Warren Construction Group, we value quality construction. We strive for excellence. We also believe in commitment. So even after a project is completed, we are there for our clients through our warranty program.
