I have a finished sun porch that is resting on 4 - 4" X 6' round steel post.
The base of these post were buried under dirt for several years and have rusted. A couple of the post have about a 1" hole near the base plate. I tried to get this fixed professionally, but the estimates have come in around $3500 to replace the existing steel posts.
I was wondering if I could replace these using 6" X 6" x 6' pressure treated lumber. The porch is 12' x 13', glassed in with a roof and tile floor, so I am assuming that it weighs quit a lot.
