"Hi, I'm Tim Gipson. I'm going to talk to you about how to repair a wood fence. Now, you see here, we've got a board that is bowed out. Now, if the fence is not too old, and these boards haven't become too dry, the simplest way to repair this, would be, we've got an upper runner here, and we've got a lower runner at the fencing board, but there is not a runner in between, which has allowed for this board to pop, so what I can do, is I can take my hammer, and I can just kind of test, and if I can push that board in without it cracking or snapping, then the best way to fix this, would be on the inside from your post, is to install a third or a middle runner, and then what we can do to accomplish that, is simply set a runner, that's going to be in between the posts, or slide it in. Then, we can either secure it through this side, or we can toenail it into the joints. Once that happens, then we can hold this board in, and then we can come in, and what I would recommend, if you have bowing situations like this, I would actually reattach this with that two by four, new two by four runner, and I'd use screws, and that would hold that in. Now, if you have broken boards, then simply all you need to do, is tear out those boards, and you've got to remember, you're going to have some expansion and contraction, so whenever you replace a board, it's usually a good idea to make sure that you leave, if you go with a green board, you've got to remember it's going to shrink up, just a little bit, but you've got to allow for some contraction, so you want to leave very thin lines, whenever you have to replace a board, on your fencing, particularly in a privacy fencing, where you want to keep it close gapped like that, so I'm Tim Gipson, with some techniques on how to repair a fence."
