Two rooms of our house do not have cement block "foundation" walls....what am I supposed to be calling it? The "skirt wall" that goes around and closes off the crawl space of the house. The crawl space to those two rooms only has plywood over it. Animals get under there and the rooms are too cold. The rest of the house has proper cement block foundation / crawl space / skirt walls. I want to rip off the plywood and build a cement block wall. I know I have to pour a cement footing.....and I know how to do that.....but How To handle it where I have treated posts for support at the corners?? I want to take those out too but how to take them out and not have the room fall off the house?? Would I build a footing PAD first on both sides of the treated Post, then go on and build the cement block tower thing on each side....then put "shims" or whatever you call the little pieces of wood that would make the cement block tower reach the house wood frame part....Joists I think it is called....the floor Joists.....and then knock out the wood post??? OR would I put those metal Leg temporary things that hold up a house in there.....build the whole footing plus the cement walls and then take out the temporary metal leg things? I think I might could put some sort of Brace under the corners and hold that up with the metal legs....?? My husband would just kill me if I let the rooms fall off the house and down the hill...so I need to figure this out......Thank you!
