This document discusses repairing historic wood windows to maintain the integrity of historic homes. It recommends repairing deteriorated features rather than replacing them, and using matching designs, colors, textures and materials when replacement is necessary. Original doors, siding, windows and trim should be restored and maintained, while adding new elements like vinyl windows or changing designs can compromise a home's integrity. Evaluating whether repair is more cost effective than replacement and maintains integrity is important. Common wood window parts like the head, jambs, sill, trim and sashes are identified, along with tools needed for repair like hammers, prying tools and new sash cords.

2. Maintain integrity by using the Secretary of the Interior Standards 6. Deteriorated historic features will be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature will match the old in design, color, texture, and, where possible, materials. Replacement of missing features will be substantiated by documentary and physical evidence.
