JGI Home Base

Our shop is where we preform the majority of the restoration and replication processes for historic windows. The shop is designed with efficiency and safety for our employees in mind. We are the most effective solution to historic restoration because of the capabilities of our workers.

With a resurgence of interest and increased national focus on restoring older buildings, JGI offers specialized services to meet those needs. Restoration work involves preserving a building’s historic character by using modern technology to improve performance and function of an historic building’s window and door systems. JGI ’s professionals have hands-on experience of not only the craftsmanship skills necessary to accomplish restoration work, but also a working knowledge of those National Park Service Standards that drive restoration activities. Jacobs Glass utilizes effective methods and means needed for restoring a building’s historic features in an environmentally secure and sustainable manner.


Our restoration team members are EPA Lead Safe certified, and we have Maine State Certified Lead Supervisors on staff who oversee work on all our projects.
