I can't find anything on the internet to help me with this and my husband and I can't agree.
We are installing both new flooring (bamboo) and replacing our carpeted stairs with hardwood. My husband says we should cut the flooring just short of the base of the stairs and leave a small gap away from the bottom riser that we'll cover with a piece of trim in case anyone ever wants to replace the flooring in the future.
I think the flooring should go all the way underneath the new riser so there is a clean joining of the floor and the stairs. If the floors do get replaced in the future it seems the boards would slide out easily enough.
The picture shows our new flooring cut just short of where the new stairs will be installed (those are the old stairs that were covered with carpet). Thanks for your input.
