Privacy fences installed in a yard are a good way to keep out the prying eyes of nosy neighbours and passersby, and to prevent people from using your yard as a cut-through. Unfortunately 6-foot fences don't always seem like enough, and you might still feel vulnerable or want to block out an unsightly object. Decorative lattice fence toppers add additional privacy as well as a little flair to an otherwise ordinary structure.
Look at the size of the posts to which your current fence is attached. Purchase posts this size to use to extend the posts above the current fence height.
Cut the new post pieces to a length of 2 feet. Measure each piece before you cut it. Sawing eats away some of the wood, so you should never do all your measuring at one time. Use a square to check the sawn end. It must be square. Sand it down if necessary to get an even surface.
Lay a new post section down and place half of a metal tie plate on top of it. Check to see that it is straight on the wood post and drill 1-1/4-inch wood screws through it to hold it in place on the post. The plate has a grid of holes to secure it. Fill as many as you can. Flip the post to its opposite side and repeat the process with a second plate. The parts of the plates that are hanging off the post will be attached to the top of the current fence posts, thereby extending the height of the posts by 2 feet. Attach the plates to the remaining posts in the same manner.
Place one of the new post sections on top of a fence post and slide the metal tie plate over the top end of the old post. Use a drill and more 1-1/4-inch screws to attach the plates to the fence post. Repeat this step with the remaining posts.
Stand on the clean side of the fence that normally wouldn't show the fence posts and place a section of preframed lattice on top of the fence. Line up the lattice frame with the posts that are extending above the fence line.
Level the lattice frame and drill pilot holes into the frames on the left and right sides so that attaching them to the post doesn't split the wood.
Insert screws and drill them through the lattice frame on the left and right sides and into the extended posts. Use 3-inch wood screws.
Paint or stain the lattice fence toppers to match the rest of your fence. Preframed wooden lattice fence toppers are available at most home improvement stores.
