Is there an easy solution to fix sloping hardwood floors? The entire house has sunk over the past 125 years. There are support beams in the basement so I can't imagine that the sloping will severly continue in my lifetime, however, there is about a 3-4 inch difference over a course of 12 feet. There is more like a bubblehump then gradually slopes away from the foundation toward the center of the home. I am referring to the second story bedroom.
