How To Easily Extend A Wooden Fence Post

When choosing a privacy solution for your backyard, there are lots of different types of wooden fences to consider. However, it's not just the material you have to think about — height is equally important. If you already have a fence you find aesthetically pleasing, but it's a little too short, there's good news. There are ways to modify its height. Indeed, you can make it taller, and it starts with increasing the posts' height – which you can do without having to dig anything up.

The fastest and cheapest way to go about this DIY is to select matching wood posts, cut them to size, and ensure that both the top of the existing post and the bottom of the addition are flat and level. That way, they can safely be stacked and attached together using post extenders. Made from galvanized (i.e., corrosion-resistant) metal, these extenders come in two forms: bracket and sleeve. The first is a flat metal plate with four pre-drilled holes. The bottom half should be screwed into the existing fence post using galvanized lag bolts, while the top half will attach to the new pole. You'll need to use two per pole (like these Step2 Mail Post Extender Brackets) installed on opposite sides of the fence for stability.

As for bracket post extenders, these are even easier to use. Simply slide the metal extender on top of the existing post, then slide the new post on top and secure it all in place with bolts. Before getting started, though, here are a few more things to consider.

Before getting started on adding a fence extension, double-check that your new desired height won't exceed what is allowed by city regulations or homeowners' association rules. Next, take a close look at what you're working with. An existing fence post should only be extended if the wood is healthy and in good condition. Make time to thoroughly check if your wooden fence is showing any signs of rotting or breaking apart. If you spot all-over damage, the post will need to be replaced entirely at which point you can simply swap it for a taller one that's your desired height. If, however, there's a trouble area that's limited to the top portion of an existing post, you can trim off the top, sand it so it's clean and level, and attach a post extender, as explained above.

Alternatively, another creative way to add height and extra privacy to an existing fence is to install a fence topper. Available in pre-cut wood and vinyl lattice panels, these can add a couple of feet to an existing fence while delivering some aesthetic interest. Panels are quickly installed with screws and anchors and can be quite affordable, as a 2-foot by 8-foot panel starts at around $14. Just keep in mind that this option will not seamlessly blend in with your existing fence, although it will deliver the desired privacy and shade.
