Question Floor Joist Problems in 100 year old house

I am new to DIY. My husband and I have a 100 year old house in Wisconsin. Our second floor bedroom has hardwood floors and is sagging really badly. This problem was not caught by the inspectors when we purchased the home two years ago. Now we can see where the previous owners tried to repair the drywall on the ceiling on the 1st floor due to cracks. I spoke with a grandson of the previous-previous owners and he told me that the reason we are having out problems is his gradmother ran 2 humidifiers on the first floor and there was so much moisture in the room that it was dripping from the 1st floor ceiling (right were the problem is)! My husband is very handy and has access to jacks. This winter we plan to tear apart the ceiling in the first floor living room to see the damage on the 2nd floor joists in the one area (basically the center of the house). I assume we will try to "beef up" the current joists by putting new ones in an anchoring them to the old. Then very gradually raising it up (I am sure in reverse order). Please let me know if you have any advice to give us & please don't scare us! Thanks!

sounds like a good plan.

wow. so the room was so humid that water was dripping from the ceiling?

i jacked my 100+yr wood frame house a couple summers back. i did the turning in a couple of days, cracked the walls knowing that i was going to remove the plaster later. i think it's important to listen to the house. turn and then listen, it's wild to hear the house creak and moan as it moves. it will also tell you what it's thinking.

It sounds like it's an isolated area in your house... i think you have a good plan. i guess the only thing i can think of is to make sure that you have support under the first floor where the jacks are going to be placed. If you go slow, turning small amounts, you can minimize the damage on the second floor. Depending on how damaged the floor joists are you may be able to sister new joists to them.

Any idea how much the floor is sagging?
Here are a couple of links:

I saw another but didn't bookmark it... it was more of what you're talking about doing... raising a floor. i'll post it if i find it.
