Bought a 150 year old Victorian where the main house beam is supported by brick and mortar posts that are crumbling. I'd like to jack up the beam and replace the 3 existing support structures. 2 questions after I put in a proper 12x12 foundation, is a steel support better than a wood post (existing span is about 8 feet currently supporting a 2 story structure with converted attic existing beam is 10x12). From what Ive read on this forum already, a 6x8 solid post would work. No idea what size steel post would work. And as far as a steel post, would the adjustable 3 units sold at Home Depot work (they support 8000#). And along that same like, could I use 2 of them for jack posts to lift the beam for the initial demolition?
