I have wooden fence panels and one side of the neighbouring wall is now very wobbly and with the storms we are getting i'm not sure how long it will hold up. The fence panels are a bit rotton but not too bad but it's all wobbly because of the actual wooden posts seem loose. It's about 11 years old now. So the question is, is it only wooden posts that become wobbly after years? If i was to replace it with concrete or metal posts will they last and not become wobbly? I want to invest in better posts, I dont mind replacing the panels once in a while but I don't want to keep replacing the posts.
