We had our carpet staircase replace with wood from them. They were recommended by a friend of ours.
They were very professional, and the new staircase looks great!
I found out later we also paid a very premium price. Neighbor of ours had the same staircase replaced for roughly half the cost.
The quality of work is definitely better on ours, but if I knew about the price, I probably wouldn't mind the lower quality to save myself $1500+.
