Hi! I'm trying to determine if an issue I'm having is something that is a safety issue that requires immediate repair, or simply just cosmetic. I noticed that in the back portion of my dining room the floors were beginning to sag and the wall alongside had a crack (though it's a 116 year old house, so not sure if that's just typical). Beneath it it appears the floor joist is twisted (I assume that's the phrase for this? It's not sitting straight). I've attached pictures of the issue. There was a small amount of mold on the joist, which I've cleaned off, but it doesn't feel like the wood is rotted and other than some discoloration on the paint, it doesn't seem different from the other joists. Is this something I have to have repaired right away for safety's sake, or is this just an annoyance? How would I go about correcting it? Any thoughts would be greatly appreciated.
P.S.: There may have been some level of water damage, but I'm not sure. During the summer I had come across some watery discharge from a floor standing AC above it, which I cleaned up but I'm not sure how long it was there. Also, there was a period where water would pool in the alley along the house near that area of the building, but this has since been remedied by extending the gutter out into the backyard. Just in case that's relevant. Thanks!
