I probably made a strategic mistake wanting to “do it all by myself”. The deck took all summer. 14’x28’. I wanted it to be as low maintenance as possible. MCA treated lumber for posts and joists. Azek PVC decking with Coretex screws and plugs. Aluminum railings. Hardware is all GoldCoat or triple zinc. Flashing membranes on joists and beam connections. Designed with SketchUp. The floor joists inside the house were not regularly spaced across the width of the deck, and the clothes dryer exhaust forced a split ledger. So getting joist hangers in the right spots required quite a bit of fettleing with SketchUp. I kicked everything up a notch in sizing, i.e. 4” posts were acceptable per building code, and I used 6”. Joists could have been 2×8, and I used 2×10, etc. The clipped corners took an enormous amount of time to frame, but were totally worth it. Same with the railings. A rectangular deck would have taken much less time, but I was only going to do this once in my lifetime, so I wanted something a little better than ordinary. The ledger is bolted to the house joists with 1/2” lag bolts. The ledger is bolted to the rim joist with Ledgerlock screws. There are a total of four lateral anchors at the corners of the split ledger, attached to the house joists with 1/2” galvanized threaded rod.The joist spacing is only 16” in one place, and the average is 13”. Lots of blocking, and hurricane ties attaching each joist to the beam.Planing the joists all level took forever, but I think it shows in the finished product. Even though the joists are MCA treated (which is supposed to be a lot less corrosive), I used G185 or better for all fasteners anyway. The tops of the joists have flashing on them to keep water from soaking in. Railing posts are bolted to joists and blocking with 5 1/2” galvanized lag bolts. The railings are 42” high, rather than the standard 36”. I fell off of each of my ladders once, but without any major damage. The Soviet judge only gave me a 2.0 on the dismounts. Very ungraceful.
