Old oak hardwood
We live in a home that still has the original oak hardwood floors, Great right well the last owners put carpet overthem and we noticed that the wood floors are starting to lift. Bad enough that my wife almost rolled her ancle.
We need to replace the floor do we leave the original hardwood(minus the parts that are lifting) and then put a layer of leveling concrete? Or are we going to have to remove all of the original hardwood?
