This is the back deck of my house which probably dates to the seventies. That's right, there are no steps to the yard! When my kids were younger we had a slide from the deck to grass. Yesterday, i used a hand sledge to knock all the railings off, used my sawzall to saw off posts and lag screws, then pulled up all the decking. The framing is sturdy and today i added blocking between joists (cut from pulled up decking) and dug two holes at outer corners which were filled with gravel and cement. Tomorrow i'll put a prefab cement footing from home depot in each hole and add two more vertical posts which will tie into framing at corners. Here is deck after a few hours of demolition:
Thanks to my neighbor Jay and houseguest Mick for help!
