Installing flooring over plywood or OSB subfloors is very common, provided the panels are structurally sound, dry, and clean. You must first ensure that the panels are securely fastened to the joists to prevent squeaks and movement. Any loose panels, raised nail heads, or swollen, uneven seams at the panel joints must be corrected. If the seams are uneven, they can telegraph through to the surface of your flooring, creating visible ridges. These areas should be patched or sanded to create a smooth, seamless transition. Make sure the subfloor is free from any debris, adhesives, or other materials that could affect the installation. If the subfloor is in poor shape, installing an additional layer of underlayment-grade plywood is a professional way to create a clean, flat surface. Always check the flooring manufacturer's requirements for moisture content in the wood subfloor before proceeding. By following these steps and ensuring a flat, solid foundation, you will provide the best environment for your new luxury vinyl or laminate floor, ensuring it stays stable and performs well for years.
