How do I upgrade construction grade stringers?
Our house was built in the 1970s and had carpet on the stairs and stringers. When I removed the carpet, I found everything underneath was construction grade. Until I could figure things out, I temporarily placed laminate on the stairs and risers and sanded and painted out the stringers. Now I know that I am going to put in stained red oak treads and white pine risers. But I have no idea what I need to do to make the stringers work too. They look HORRIBLE! Help please.
