I would greatly appreciate it if someone could look at the pictures I have posted on photobucket and suggest how I can fix my problem. I have added descriptions to each picture to explain the problem. The drywall in question is in a 10 year old home if that helps. My guess is that they used some type of paper tape to join sections of drywall and over time the mud that was applied to the tape is seperating away from the tape. I don't see any water damage. All help is greatly appreciated. Thank you in advance!
