The crew removes the old flooring, inspects the subfloor for moisture damage, rot, or squeaks, replaces damaged sections of plywood or OSB, and applies self-leveling compound where the surface is uneven. Only after the subfloor is flat and dry does the new material go down.
Specifics worth flagging
Older homes more often have plank subfloors, uneven joists, and prior water damage from appliance or plumbing leaks. Newer construction is usually a cleaner, faster scope with plywood subfloors ready for new flooring with minimal prep.
