When I bought my house, the deck was in poor shape. Enough to pass inspection, but the deck boards have not been sealed or washed in years. There are way too many splintering and cracked boards. I decided it would be better and easier just to cover as much as possible with Trex. I purchased a rail kit along with the Trex 4 x 4 sleeves (so the lattice and rails will be removed).
I was wondering how I could get composite post sleeves to fit over these posts. Can I forgo sleeving these posts and attach the aluminum directly? How can I make this work without it looking terrible or causing any safety issues? I am concerned that cutting the sleeve might pose a safety issue down the line.
