Step 1: Determine the cause of the squeaky floor Squeaky wooden floors can be caused by the movement between the individual floorboards, between the floorboards and the sub-flooring, or between the sub-flooring and the floor joists underneath. Determine the cause of the squeak and follow the appropriate steps.
Step 2: Use lubricant on squeaks caused by movement between floorboards To silence squeaking caused by movement between floorboards, lubricate the rubbing surface around the source of the noise with powdered graphite or talcum powder. Work the lubricant in by stepping on the section repeatedly until the squeaking is gone. Wipe away any excess lubricant.
Step 3: Refasten warped floorboards that have pulled away from the sub-flooring Squeaks can also be caused by movement between the floorboards and the sub-flooring. To refasten the floorboards, drill pilot holes into the face of the floorboard. Drill the holes a half an inch away from the edge of the board to avoid splitting.
Drill pilot holes into the face of the floorboard.
Step 6: For a better alternative to nails, use screws to refasten the floorboard to the sub-flooring Drill a pilot hole into the floorboard using a profile bit, which will allow the screw to set below the level of the floorboard. Be sure to check for any mechanical, plumbing, or electrical equipment in the area before drilling.

Step 9: Insert the bung into the hole Cover the sides of the bung with wood glue. Press or lightly tap the bung into the hole. Be sure that the rough side of the bung is facing up and the grain is in line with the floorboard.
Step 10: Trim, sand, and stain the bung After the glue has dried, trim the excess bung material with a chisel if necessary. Lightly sand the bung to make the surface flush and smooth. Use a matching stain, gloss, or surface finish on the bung.
Step 11: Some squeaks are caused by friction between the sub-flooring and the floor joists If you have access to the underside of the floor, look for spaces between the sub-flooring and the joists that might be causing the squeaks.
