Here's How To Do It:

Step 1: Remove Old Decking

Begin by removing old decking if necessary. Unscrew the old deck beams from the joists so as not to damage the deck frame. Then place the first post at the corner of the deck, just inside the rim joists. For this project, the post was placed between two boards that make up the rim joists. If there is a space between the joists and the post, use a shim to fill the gap.

Step 2: Add Placers Between Joists

Attach the post to the rim joists by screwing 1/2-inch diameter stainless-steel bolts with 1-1/2 inch heavy duty washers through the joists and into the post. Make sure the bolts are placed towards the outer edges of the post and not in the center. Add placers (fillers) between the two rim joists. Secure these using 2-inch nails.

Step 3: Add the Deck Trim

Attach the trim to the outer deck frame joists using countersink screws. Use a jigsaw to cut out the post area when placing the trim around the posts to get a nice, snug fit.
