In the end the original floor creaked, moved, and needed to be replaced because it was installed poorly and on top of the original floor tiles. The second company that came in was extremely professional and took the time to not only explain but show us why we needed to rip up the entire floor and reinstall properly. They removed all the old tile (which only took them an hour) and all materials until there was just cement, they then poured a floor leveling liquid product onto the floor and let it run where ever it wanted to ensure the floor was then level. The liquid took about a day to dry.

The next day they installed some type of fabric between the wood and cement and then installed the wood flooring on top of that. The difference between the two installs is night and day. The floor around my house no longer creaks, moans, or moves around when shifting your weight.

My opinion...there's only a few material things in life that you don't half ass....your car, your bed, and the floor you're standing on
