Ganneston Construction Corp

Johnson Hall Opera House was incredibly fortunate to have Ganneston Construction as our construction company and general manager of our theater renovation. They worked tirelessly to rebuild the oldest operating opera house in Maine and they did an absolutely beautiful job. I would highly recommend them for any project. Their team was top notch from the owner to the crew.

Project was completed in a timely manner. Every facet of the project was organized so that there was no down time. Workmen were a pleasure to have around the rest of the building. If they could be helpful, they were quite willing to lend a hand.Service: General building construction

Stacey Morrison and her crew have been wonderful to work with! Ganneston was willing to perform extensive value engineering to get our project within our budgetary limitations. The quality of work performed by Ganneston and their subcontractors have been excellent. We are very happy to have selected them as our contractor.
