any defective or rotted wood parts.

Place one side of the tape against the vertical leg of the stool, and work the tape into the corner before applying to the sill. Press down firmly. The tape will not cover the sill depth completely under the new window.
Note: If needed, blocking/shims may need to be placed where the existing balances were located.
