Abstract: A stairway with a finished skirt/fascia board is formed using parallel stringers and tread/riser support brackets spaced and aligned along the stringers. The brackets are temporarily and pivotally attached to stringers and the stringers are moved parallel to and relative to each other to orient the stringers for the slope of the stairway. The pivotal attachment of the brackets to one of the stringers and the unattached stringer is moved into contact with the other stringer at mating faces. The brackets are them permanently attached to the parallel stringers. The mating faces of the stringers form a finished skirt/fascia board for the stairway. Several variations in contoured faces, including tongue and groove contours, for the mating surfaces provide for a smooth and clean looking skirt/fascia board on a finished stairway.
