Wooden Window Repair will cover the methodology necessary to repair and/or upgrade existing wood windows in historic homes. The course will cover basic window types and anatomy while focusing on the procedures necessary to restore traditional windows to a functional state. Topics to be covered include but are not limited to: the identification and documentation of existing conditions; deterioration processes; window sash and frame removal and transport; the development of a preservation methodology (advantages and disadvantages of repairing vs. replacing) and the evaluation of repair options including epoxy repairs, Dutchman and full or partial replacement; how to successfully remove glass and dissemble and reassemble sashes; the recreation of molding profiles using hand tools, stationary shop tools and hand-made scrapers; paint removal options including abrasion, chemical, heat and steam; re-glazing methodology including point placement, bed glazing and re-glazing techniques; preparation for painting including sanding and priming, painting and waxing techniques designed to ensure proper operation; counterbalance systems and their repair; and the options associated with thermally upgrading existing window systems including the addition of insulating glass, weather stripping, interior and exterior storm windows and thermal blinds and shutters. Students will actively participate by taking a window through the entire process from start to finish.
