I've got a six foot high wooden fence..... a proper constructed one and
not a fence panel one. Its got 4"x"4" posts, several of which are quite
badly rotten just below the surface. How easy is it to replace the
rotten posts in isolation without disturbing the rest of the fence?
I agree that this is an easy repair method, if you don't mind the
But if the OP wants to *replace* we need more details of the
construction, and also to ask how old it was, and whether alternative
precautions are necessary to extend the life in future.
I did several like that except with the bigger spur posts you can get.
You use a big SDS drill to break the concrete on one side, dig out the
rotten post from the remaining concrete fill the resulting channel and
drop the spur in, bolt it up and fill in the rest of the hole.
It doesn't need to a continuous ring of new concrete as it requires
virtually no tensile strength.
I put new posts midway between the old ones, and left the old ones in
place. I intended to remove them but couldn't really see the point when
it came to it. I would have had to join the rails where the old posts
Saw the ends off the arris rails up against the rotten posts, lift out
the panel, replace the posts (as others have said, this is easy or hard
depending on how much concrete there is), replace the posts (don't
bother making the mortices), refit the panel using these brackets
attach the ends of the arris rails.
If there's too much concrete around the old post bases then divide a
two-bay run into a three-bay run so you can put the new posts somewhere
However you decide to tackle it, I would use concrete spurs and bolt the
new (or, possibly, old) posts to them so they won't rot again.

I hadn't considered using concrete repair spurs. Perhaps that would be
the easiest option. I would still have to chip away at the concrete at
the base of the rotted post to enable the spurs to go deep enough but it
sounds easier than replacing the posts. Thanks.
