The studio’s approach to any restoration project includes attention to the detail and craftsmanship of the original window. Existing conditions are documented through photographs, annotated rubbings and written notes. They serve as a guide in understanding how a window was built, the materials and techniques used in its creation and any previous attempts at repair or restoration. While the lead came in a stained glass window has a limited lifespan, the glass can last for centuries. Wherever possible, all original broken glass is mended by edge gluing the broken pieces with either silicone or epoxy or by copper foiling the broken pieces. Windows are then re-leaded with new restoration grade lead came, thereby re-establishing their structural integrity and creating a lasting work that is respectful of the original.
