I have a wood picket fence, 44" high, with about 35 fence posts, round, 4" in diameter iirc.
I have two problems.
1) One is loose. It feels like it has broken off maybe 8" above the bottom end. How to fix it????
I thought I would disconnect it from the fence, pull it out (which I think will be easy), take a replacement (easy to find), cut it to the same length as the piece that comes out**, put the post in plus some instacrete or sackcrete***, pour in some water, and let it harden.
Is that okay? If the part of the first post every rots away, and the post sinks, I can replace it again.
**Well actually I would put the new post in and use it like a pile driver to crush the old post stub as much as I can. Then extend a string from the posts to the left and right of this one, and mark this one so it's the same height as the other two. *** (the speedy stuff or the regular stuff both work, I hear)
2) Some of the posts are hollow in the top center, going down 2, 3 even maybe 4 inches. . Water sits on them and the wood rots or crumbles. Sometimes green plant life grows in the holes
a) I thought I should drill a hole in the side so the water drains out. or b) I should fill the holes with something, something that looks like the original post if possible. . I had tried outdoor wood glue mixed with a lot of sawdust. but that broke up.
