Pre-Drill and Secure Mitered Corners

What happens here

To prevent the trim boards from splitting and to ensure a strong, lasting attachment, holes are pre-drilled through the exterior trim and into the underlying structure. An impact driver is then used to drive screws through these pre-drilled holes, securely fastening the mitered trim pieces in place. This process is shown multiple times from different angles, highlighting the systematic approach to securing the corners.

Goal: Permanently attach the mitered exterior trim with screws.
