Hello, Thanks for all your help in advance Currently we are redoing our stairs. They were initially open stairs that were completely carpeted with iron balusters We wanted to close them up and use false treads on both ends of each real tread, then place carpet in the middle that would end up being flush with the false treads Due to the nature of the stairs the risers needed to be in the front of the real treads and thus the tread could not overhang the new riser. There is a squared edge as seen in the pic Our thought was to add a bullnose piece to the end of squared edge so that carpet would be able to flow over. I was told by the carpet guy that we cannot add this piece as it is likely to break. What he would like to do is place 1/2" plywood on top of the riser (thus making it flush with the false treads on the size) that would overhand the tread and then put carpet on top. This would mean that the carpet would not be flush with the false treads but be thicker (possibly an inch when accounting for the padding) Other people have told us that with glue and nails that bullnose piece will not possibly break. Certainly they sell bullnose additional pieces for this very reason I think. So the questions are, can we use these pieces and will they hold up over time. If any one has any suggestions or experience with this, your help would be much appreciated.
