My fiancee and I are looking to buy a house built in the late 1800's; the upstairs bedrooms were carpeted at some point, but we'd like to tear out the carpet and put in wood flooring. However, the planks that make up the floor beneath the carpet have dipped over the years (structurally sound, but definitely not flat).
Is it possible to put a floating floor (e.g. Pergo) in place when the subfloor isn't completely flat? If not, are there any comparable (as far as price) options? Thanks in advance.
