Caulk should also be avoided around movable parts, as it may cause the window to seal shut or impede its operation.

The ledge above the window frame also doesn’t need caulk, as it has a drip edge that helps keep the frame dry. If replacing siding or framing, leave the top of the window caulk-free. This will prevent moisture from entering the window and prevent potential damage.
