In this video, This Old House landscape contractor Roger Cook and fencing contractor Mike McLaughlin install a low-maintenance, long-lasting vinyl fence.
How to Install Vinyl Fence Posts
- Stretch a string across the yard to establish the fence line. Use a line level to ensure the string is level.
- When starting against an existing fence post or other object, dig the first fence-post hole to 32 inches deep using a manual post-hole digger.
- Prepare the vinyl fence posts by first cutting a pressure-treated 5x5 into 24-inch-long pieces. Insert a piece of 5x5 inside the hollow vinyl post. Secure it with galvanized screws.
- Mix water and concrete in a wheelbarrow.
- Stand fence post in hole and fill around it with concrete. Keep the concrete 2 inches below grade.
- Use a 4-foot level to ensure that the post is perfectly plumb.
- Use a power auger to dig the remaining fence-post holes.
- Connect the first fence panel to the post, then secure it with screws fitted with snap caps.
- Continue to install posts and panels to complete the run of fencing.
- Install the top rail, and then insert the short, square spindles. Secure the spindles with galvanized screws.
- Finish the fence by installing a cap to the top of each post. Secure the caps with PVC cement.
