Dig a hole for the newel post at the lower end of the first stair railing. (The railings will attach to porch columns at their upper end.) Begin with a shovel and finish with a clamshell posthole digger. Dumping the dirt directly into a wheelbarrow will save moving the dirt twice.
Cut the composite sleeve for the newel post to length using a chop saw.
Cut and place a pressure-treated four-by-four post inside the sleeve and then cap both ends of the sleeve with the special plastic inserts provided for the railing system.
Position the post assembly in the hole with one face square to the house/porch and use a bar level to ensure it is vertical.
Hold the post in position and backfill the hole with gravel and soil. Repeat the last five steps for the other newel post.
