Smoothing (or "tooling") the caulk forces the material deep into the joint and creates a clean, concave finish that sheds water effectively.

Fixed windows are sealed at their perimeter to prevent water infiltration, air leakage, and heat transfer. Common seal failures result from degraded glazing compound, failed backer rod/caulk joints, glass-to-frame seal deterioration, or failed insulated glass unit (IGU) edge seals (desiccant failure, fogging). Resealing can address perimeter leaks; IGU replacement is required for internal seal failure. You cannot seal over old, cracked caulk
