Abstract: A surround molding assembly for a doorway or window of a structure such as a residential home or a commercial building. A mantle molding member is provided and fixedly secured over a top portion of the doorway without the need for external fastening elements. An installation support member is arranged within the molding member to support the outer surface of the molding member. An internal corner member is positioned adjacent each end of the mantle molding member and each directs water running onto the mantle molding member away from the doorway. Another trim assembly, including a base having a decorative portion and a ring are used to conceal a base flange. The trim assembly may be used in conjunction with a mantle assembly to provide a decorative molding that directs water away from a door or window.
