About Us


We never rest on the status quo. We continually seek opportunities for growth through new markets, advancing services, and the professional development of our employees. 




We are family oriented with a culture of teamwork, respect and responsibility for the community in which we live and work. 

Located in historic Auburn, ME on the banks of the Androscoggin River, Prehung Doors has been in the door and window business for over 30 years. We offer a wide selection of millwork products for both residential and commercial projects.  Over the course of 3 decades under Owner Jim Murphy’s guidance, the company has become the most trusted and reliable source for multifamily residential projects requiring custom built pre-hung doors in the region.  This fact is driven by our customers who choose to come back to us for project after project. In April of 2022, Jim passed the “baton of leadership” over to the Manganaro Building Group who acquired the company to further the already considerable growth they had experienced.  Today, Jim Murphy continues on as a full time consultant to the company with our current management team to build upon Jim’s founding vision of great product and great service to drive great growth.
