I recently had my stair done by a contractor. Im new in this I need help. I was charge a lot of money for 28 steps closed in flooring material with nosing and paint grade riser and skirt unpainted. I dont think they put all that, there's a gap between the wall and the steps, you can insert a silver dollar inbetween them. I am having a meeting with the contractor next week regarding this problem. I wish that maybe you could send me a sketch or a picture indicated above. Help Help what is a paint grade riser and skirt and nosing.
