I want to install new hardwood flooring in my living room. The house was built in the 1960's and the hardwood currently creeks in most places. I have asked around on how I should approach this and came up with the following options:
1) rip out old hardwood and install new plywood subfloor, then install hardwood on top
2) screw down old hardwood every 6 inches and float engineered wood on top. In this situation, I was told nailing down solid wood wouldn't be a good idea.
keep in mind that there is currently a 3/4 inch step between the hardwood and the newly installed tile surrounding this room.
