A retrofit casing head filler member has a front face, a rear face, an upper edge, a lower edge, and opposite side edges, and is designed for installation over a conventional arched casing head so as to cover any drywall regions exposed by removal of a rectangular casing head. The lower edge of the filler member has a predetermined radius of curvature matching the radius of curvature of the upper edge of the casing head. The filler member may be of reduced height in its central region and has a maximum height at its side edges to provide increased area in these regions to cover any exposed unfinished corners of the underlying drywall.
