Label every piece so it returns to its exact original opening.Hardware Tagging: Remove and catalog all initial sheaves, lifts, and sash locks.Stage 2: Stripping and RepairPaint Removal: Safely strip layers of old, often lead-based paint utilizing infrared heating systems, chemical strippers, or hand scraping. Never use open flames or power sanders that produce hazardous airborne dust.Wood Repair: Clean out any decomposed locations. Support small rot with liquid wood hardener, or use epoxy wood filler for larger gouges. For serious damage, an experienced restorer will "Dutchman" in a piece of matching old-growth wood.Sanding: Smooth the wood surface areas with medium-to-fine-grit sandpaper, making sure not to round over crisp architectural profiles.Stage 3: Glazing and FinishingPriming and Painting: Apply a top quality outside guide followed by 2 coats of oil- or acrylic-latex paint to seal the wood entirely versus moisture.Reglazing: Remove old, breakable putty and loose glazing points.

Research studies carried out by the National Trust for Historic Preservation have shown that a brought back historic window paired with a quality wooden or aluminum storm window performs comparably to a new double-pane replacement window. Storm windows develop an important dead-air area that considerably reduces heat transfer, while still allowing the historic interior window to remain visible and functional.Vital Tools for Window RestorationStarting a repair task requires specialized gear.
