Install Vertical Corner Trim

What happens here

With the horizontal siding in place and the corner prepared, take the vertical corner trim piece. This trim is typically designed to cap the ends of the horizontal siding panels, providing a clean, finished appearance and protecting the edges. Carefully align the trim piece vertically from the bottom of the wall to the top, ensuring it covers the exposed edges of the horizontal siding panels and fits snugly into the gaps created in step 1. Once properly aligned, secure the corner trim to the building structure, typically using finish nails or screws that are either hidden or matched to the trim color. Press firmly to ensure a tight fit and a seamless transition.

Goal: This final step involves placing and securing the pre-cut or prepared vertical corner trim over the corner where the horizontal siding panels meet.
