Recently, I had my patio mudjacked because it was sloping toward the house. A trellis I have next to the patio has also sunk over the years on the side near the house. I'm thinking about cutting the post of the side of the trellis near the house about 4 inches from the foundation and adding a block of the same material to bring it back up to level. It's about 3 inches of material that would need to be added to bring it to level. Does this sound crazy? Is there a better way?
