Hi, recently I noticed that 2 areas on my first floor seem to be dropping, causing the floor to be uneven. Both areas happen to be above old basement windows that have been covered by brick and concrete before I moved in. I live in an old home in South Philadelphia, and have attached a picture of the floor...any insight on what might be causing this, or what I can do to correct it? Thank you in advance for any feedback.

Looks like the band or ceil is rotting, or it could be a header rotting if there is or was a window below. You really do need to get under there and check it out, it isn't going to get better on its own.

Ya you need to get down in the crawlspace under this with a hammer and start taping. I bet something isn't solid.

Use some clear painters caulk and caulk the gap and problem solved.

could have termites eating the house band, have you called an exterminator? was there quarter round or shoe mold down at one point? looks like it was...

Could be a lot of things, insect infestation, deck installed right up aginst the siding cause rot, siding not ran past the foundation so water can get in and rot the rim joist, floor joist spliting where they notched them to sit on the rim joist.
