Yes, you can install luxury vinyl plank, or LVP, flooring directly over existing hardwood floors. However, LVP will not fix structural issues like squeaky floors or nail pops caused by movement in the subfloor or joists. It is important to secure loose hardwood boards and address squeaks first to prevent trapping those problems beneath your new floor. Installing LVP over hardwood is often a reversible option if the structure is solid and stable before installation.
