I need to rebuild my deck this spring. I had hoped to just redo decking and rails, but upon inspection today I think the posts need replacing.
They are 6x6 set in the ground and cast in concrete, I am guessing they are 25-30 years old and show significant rot. The rest of the structure is in great shape and I don't want to do a full tear down and rebuild, so I would like to replace the posts in place. Looking at about 10-12 that need replacing.
What is my best option here? I am thinking I could pull the existing posts out of the concrete using a high lift jack with some chain and then pouring a new footer over top of the existing footer and embedding some threaded rod and using a post box to mount the new posts to so the new posts are all above grade. What I don't know is how much a pain in the butt pulling the posts will be. The deck is about waist high above grade so I do have some room to work and the posts are not too tall.
Has anyone done this? I assume as long as I clean the old footer well and use a sonotube pouring the new footer over the old one and filling in the hole where the post was it would bond with the old concrete and be sufficient.
I have zero desire to dig out the old footers......
