So from what I understand, ordinarily when you're jacking up floor joists you go 1/4" at a time and you expect to hear creaking and groaning.
I've had to jack up floor joists more than that, even 1" at a time, just to get them off the "supports" I'm removing to put in my temporary support beams. Not a sound. Am I deaf? Is my house built from wet noodles?
On one hand I'm wondering if something ain't quite right. On the other, I'm wondering if this means I might have enough flexibility in my structure that I have a good chance of being able to straighten it out before I start sistering and getting the structure into a better state. I.E. the old structure will conform well to the newer more rigid structure.
Please do NOT consider any "before" picture of my house as any kind of endorsement of any particular construction method. In fact, you should probably assume that if I post a "before" picture, I am posting it because I am soliciting advice on a proper replacement for one of MANY things done wrong by a previous owner.
