What flooring options create the quietest home environment?
You can install LVP over hardwood floors, but LVP will not fix squeaky hardwood or nail pops, and it can trap issues you will still need to solve later. If the goal is a quieter, longer lasting floor, address squeaks at the joists and secure loose boards first, then decide between refinishing hardwood or a floating LVP as a reversible stopgap. For many homes, fixing squeaks then refinishing offers the best long term value and look.
