How to Fix a Snap in the Decking

Using a putty knife or chisel, clear the area surrounding the screw hole before attempting to repair a snapped decking screw. After that, remove the problematic screw from the board by unscrewing it with a Phillips head screwdriver.

Change the screw with one that is the same size and threads through the wood. With a hammer and socket wrench, install the new screw, then reattach any fasteners that were taken off in step four.

Finally, manually verify that all screws are secure before sanding down any protruding edges on the board to complete the project.
