There is definitely less sag in the floor where I have been raising it. They say you can safely raise 1/8” daily but I’m not in a rush. I do about that much once a week. I find that this gives me time to get accustomed to the change and decided if it is ok to stop or not. At first I see the improvement and think ok it’s done, but after walking on it and looking at it for a few days I see where it has improved and where it is still not level. I think I’m going to have to start checking it with a level so I know when its ok to stop.

Then I’ll worry about putting in the permanent columns. I found these in “This Old House” magazine. I think I’m going to use them for the footings once I get to that point.

I’m hoping this will help with the sag in the floor on the 2nd floor as well but I’m not sure.
