To fix a squeaky floorboard, identify the source of the squeak, often due to loose nails or screws. Secure the loose board by driving screws or nails into the subfloor, or use a lubricant like talcum powder or a silicone spray between the board and subfloor. If needed, reinforce the area with additional support.
