My house was built sometime in the 30's or 40's. The does not have any footers for the foundation and it basically was built on rock pillers on the ground. The previous owner tore out the old floors and to give the the new sub floor clearance he shoveled out about a foot of dirt and then placed concrete blocks underneath in various places and then installed new joist and plywood. Basically the house sits on blocks without any kind of footers. I've noticed 2 cracks in the tile floor in the bathroom and 1 crack in a wall in the bathroom and 1 crack in a corner of the tile in the wall around the tub. It concerns me because it seems that the house is slowly shifting or maybe sinking in certain spots. The house is roughly 12 inches off the ground. My question is. Is it possible to lift he house and put it on a block foundation? Also what can I expect to pay here in GA? Any advice would be much appreciated.
