Completing the Trim on the Oriel Windows

The western red cedar decking is complete on one side of the house and Tim Berky, the general contractor, is completing trim on the oriel windows that face onto the deck. Berky begins by covering the existing board with MDO (medium density overlay) to create a new surface over the underboard, an ice and water barrier, and copper flashing installed to keep water away from the house. Berky then installs corner dressing to trim out the outside of the window base. At the top, he will apply two layers with casing and corner board that he nails into place with a nailgun.
