Hello I have a small deck (approximately 3.5'X 6') off an enclosed porch and in the winter time the deck seems to suffer from frost heave, which I believe is being caused from the stairs pushing up on the 6x6 post closest to the house. You can see in the pictures that the deck is still lifted up, and the right hand side closest to the house and porch corner seems to be the worst. What are your suggestions to re-leveling it and preventing it from heaving again? The deck is attached to the porch with ledger board, and held up by 6x6 posts on the other side. Thank You!
