I would have shimmed the post so that it was supporting the house a bit so that time would not make that part sag. Then the post would be tight. Raise front with another post and hydrauluc lifts. shim old posts, lower lifts. Then put decorative trim around post bottoms. Just hate seeing the loose post.
I know for a fact PVC and Azek trim were out 3 years ago... hahaha... This little wood trim is going to rot completely out in a year or 2 with some good moisture and rains
