Secure any loose railings, posts and spindles. Wood spindles on an indoor staircase can be stabilized by dipping a wooden toothpick in glue and wedging it in where the spindle goes into the handrail. After the glue dries, simply trim away the excess toothpick with a utility knife. To secure bolted-on outdoor railing posts, remove loose bolts and replace, adding a cold weather epoxy to the bolt holes to help lock fasteners in place.
