We could not have asked for a more experienced, practical, and responsive builder. Peter was in on our project from the beginning, generous with his advice, and patient with our process. He has assembled a terrific crew, whom we quickly grew to know and trust. Warren Construction Group has our highest recommendation.

Warren Construction and its President, Peter Warren, played a singular role in leading Hebron Academy to complete its major construction project, a transformative Athletic and Recreation Center, on time and within an extremely tight budget. As construction manager and general contractor, Warren teamed and worked closely with architects and school leaders to find creative ways to afford and include all the special extra features in a remarkable, message- sending facility that changed school community dynamic. Warren knows schools and nonprofit decision-making.

We really worked together to get the job done, and I think Warren Construction Group contributed as much to the design process and to solving the issues as anyone involved. It was a winning combination.

It has been my pleasure to work with Peter Warren and the crew of Warren Construction on the building/renovation project.  Our historically significant building, in a highly visible location on Main Street presented a unique challenge to Peter as we were combining new construction with renovation.  He faced each challenge in a professional, ethical manner.  His expertise led to a very successful outcome.

Without Warren Construction Group's fine craftsmanship and leadership the project would not have been nearly as successful.

We are delighted with the renovation of our kitchen.  The workmanship and attention to details were exceptional.  I cannot say enough about the people doing the work; everyone was courteous, respectful of our home, responsive to our questions and requests, worked hard all of the time, and provided the highest level of craftsmanship.

You hired a great contractor in Peter Warren.  He is honest, fair and a great rep for owners in the construction process.  His company will give you an excellent value for your investment.


Thank you and your wonderful, professional crew for my beautiful and functional kitchen!  Every member of the Warren team was an expert in their field who imposed the highest of standards to their work.  Additionally they were friendly, patient, tidy and team and task oriented.
