Can I install DIY flooring on any type of subfloor?

DIY flooring can be installed on many subfloors, but success depends on flatness and material. LVP and laminate require subfloors flat within three sixteenths of an inch. Common acceptable surfaces include plywood, concrete, and existing vinyl if in good condition. Uneven or damaged subfloors require leveling or replacement before installation. Checking surface moisture levels is essential to prevent future problems. Proper subfloor prep guarantees stable, long-lasting flooring installation, especially important in pet-friendly homes.
