I've heard hardwood flooring is difficult to install sometimes. What makes it hard?

It isn't always super difficult, but it can be. When you do hardwood flooring, you have to also think about the base around the flooring. So very often you have to take the base up, the shoe needs to come off, when you do hardwood flooring, you have to also think about the base shoe and the base around the flooring. So, very often you have to take the base up, and you have to take the base shoe off. If you're floating a floor like you would with a laminate floor, you wouldn't take it right to the wall, you would take it about a quarter of an inch off of the wall. Then, you would put the base over it. The whole process can just get kind of convoluted depending on how you need to deal with the base.
