How to Add 2 Feet of Height to an Existing Wood Fence
- 1). Count the number of posts along the fence line and cut the same number of extension posts down to 2 feet in height using a saw.
- 2). Attach one end of a metal tie plate to an end of one 2-foot-tall extension post using four to six 1 1/4-inch screws. Also attach another plate to the other side of the same extension post, so both plates are parallel.
- 3). Stand an extension post over an existing corner post. Insert 6 screws through the holes along each metal tie plate that penetrate the existing post and join the two posts together. Repeat the process of joining the remaining 2-foot-tall extension posts to the remaining posts along the fence line.
- 4). Measure the space between adjacent posts along the fence line and cut a sheet of lattice to the same width. Also cut it down to 2 feet in height using a table saw.
- 5). Cut lengths of 2-inch-by-2-inch lumber to frame each lattice sheet. Use a miter saw to bevel-cut the edges of the wooden boards for frames at 45 degrees.
- 6). Position a router saw along a corner of a 2-inch-by-2-inch board and form a grove along its side into which an edge of the lattice panel will rest. Repeat the process of forming a groove along a side of each board.
- 7). Position an edge of the lattice sheet into a 2-inch-by-2-inch board and push so it fits snugly inside. Continue to frame each edge of the lattice panel, ensuring the beveled edges of sides rest against each other.
- 8). Drill three pilot holes through the end of each long framing board, and one through the corner of each short end. Insert a 2-inch screw into each hole to penetrate the wood and hold the structure together.
- 9). Enlist a helper to hold a framed lattice section directly above the existing frame between two adjacent post extensions. Use a carpenter's level to ensure it is level and plumb, or adjust its position if necessary. Join the frames at the sides of each lattice panel to the post using 3-inch screws.
