Dear James: I just moved into an older house, and a lot of the drywall tape is coming loose and needs retaping. Why did it come loose, and how should I replace it? —Randall N.
Dear Randall: It is not uncommon for drywall tape to come loose after many years. A change in humidity and temperature levels inside a house can gradually deteriorate the drywall compound that holds the drywall tape tight over the drywall joint. When you start to pull it off, you will likely notice additional loose sections.
