Moderate Degree of Rot Considerable sill or box frame replacement increases labor and materials. High Glazing Type Switching from single glazing to vacuum glass or slim double glazing. High Accessibility Requirements for scaffolding or high-reach platforms. Moderate Paint Stripping Total elimination of lead-based paints (requires professional security equipment).
