Once you have determined the property line and legal setback, mark out the location of the fence. Mark the locations of the corner post holes with spray paint. Mark the locations of the remaining line posts, keeping the distance between the posts evenly spaced at approximately 8’.
Using a post hole digger, dig holes approximately 24" deep and 10" in diameter. Add a few inches of gravel to the bottom of the holes for drainage. Insert corner posts in holes. Ensure the posts are level and plumb. Temporarily brace posts with 2" x 4"s attached to post tops and ground.
Run a string line from the top edges of the corner posts. Make sure the string is taut and level. This provides a guide to ensure that the posts are all installed at the same height. Install remaining line posts checking that each is plumb and at the same height as the corner posts.
Mix fast-drying cement according to manufacturer's directions and pour in holes. Leave the 2" x 4" bracing in place overnight while the cement cures. Remove the bracing. Apply PVC cement to the inside of the post caps and then install atop posts.
