What are common installation mistakes with LVP over hardwood floors?

Common mistakes when installing luxury vinyl plank flooring over hardwood include neglecting to fix squeaky subfloor movement, skipping expansion gaps, and failing to use a proper underpad. These errors cause trapped squeaks, floor buckling, and reduced durability. The best practice is to secure loose boards and joists first, install a quality noise-reducing pad, maintain expansion gaps, and only then float the LVP to assure a stable, long-lasting floor.
