We bought an older home and are updating everything. The floors and cabinets are the yellow oak. In our last home, we had the floors re-stained, but my wife has decided she wants vinyl plank flooring instead. We’ve done a lot of research, and have decided to do the project. My thought was to go right over the oak flooring, but when she was at a flooring store, the owner recommended ripping the oak out and then putting the vinyl down. His reasoning was so that the floor could be made level if it isn’t. I would think going over the oak would make for a more sturdy floor, and I haven’t seen any low or high spots anyway. Plus, the oak is thicker than the vinyl, so all my door jambs would be high at the floor unless I laid subfloor down over the current subfloor. That seems like a lot of extra work and money too me. What’s the consensus?
