Hi. I'm looking to replace my rotting patio posts with 6x6 PT lumber. Seems easy enough, but not so. While measuring I noticed that the brick that the posts are resting on is not level. It dips by about half an inch in the front. I am not sure how I should combat this. The 6x6's will be resting on 1/2" aluminum rests to prevent direct ground contact just like the old posts. I am a bit of a novice in the world of carpentry, but I would really like to get this done before the cold sets in. I've watched about a dozen or so youtube vids on replacing patio posts but none address this particular problem facing me. Please help!!!!
