Hi. Looks like I am in for some experience. I have a nice deck,
which is supported by 6 x 6 posts. Unfortunately, I have found that
two of the posts are simply driven into the ground, and not on a
concrete footing or pier. In addition, those two posts are, you
guessed it, rotting out. In order to replace the posts I would have
to remove the deck "skirt" and some decking, and then detach the post
from the deck joist, where it is nailed (not lag-bolted) to the post.
I don't see any real way to remove all the nails without damaging the
attaching pieces. If possible, I think a lap joint cut into the deck
post would work well. I'll have to pour a footing, but after that is
done, I think I could put in a lap jointed post and lag the two posts
together. I'd sure like to hear some comments about this idea.
Thanks.
