The nails eventually pop when the house is settling. We fix all of ours before we paint a room. You screw the drywall down, plaster, sand and then paint. If you get too many nail pops, the ceiling can sag a bit, but it's not a big deal. It is time consuming to fix, but a handyman or drywall guy can do it.
The condensations streaks- I have no clue.
Thanks. We are concerned that the nail pops are otherwise related to the streaks because everything started happening at once. The house was built in the late 60s.
