General Specifications for Repair of Wood Windows
Often weathered wooden windows are replaced instead of repaired in spite of the inherent durability of their materials. Unless truly custom-made of the highest grade materials, replacement windows will never fit, and thus never function, as well as the originals. Repair has repeatedly been shown to be the most cost-effective method, when work on tenoned windows is carried out effectively in batches after an initial triage process.
This document covers everything from consolidation to strengthen weathered and weakened wood fibers, epoxy patching to infill weathered areas of rails, recreation of missing tenons and sections of muntins and glass rabbets, and proper procedures for glazing.
