Using lead-safe work practices, Alpine removed the window sashes and stripped them to bare wood off site. Due to the age and size of the sashes, a significant amount of epoxy repairs were needed for both the window frames and sashes to preserve the window systems. Some of the original glass had broken over the years, but Alpine was able to locate restoration glass that matched the bubbles and distortions of the original glass, and the repair work was unnoticeable. Alpine then painted the windows and re-hung them on new copper chains with reproduction brass weather-stripping for a usable, historically accurate final product.
