A system for trimming interior walls includes a plurality of base boards and fenestration casing boards for mounting along an edge of the wall for forming an attractive edge face of the wall. Each board has a front face with a continuously longitudinally extending groove with the rear face of the board being fastened to the wall by a series of screws at spaced positions along the board with the screws being recessed in the groove. An extruded plastic strip is inserted into the groove along the length of the board so as to cover the groove and the screws therein. The casing boards include an extra fastening connector along the rear of the board at the jamb. Corner pieces are provided which are hollow moldings to cover the ends of the boards with either a groove for a part of the strip or a simulated ridge matching the strip.
