Seams Pulling Up, Due to Unstable Wall Underneath

Digital Image

Digital ImageHere you see a seam that is not lying flat. As the paper dried, it pulled taught, and, because the surface below was unstable, the wallpaper pulled some of the paint away from the Sheetrock. In addition, there were 1″ x 3″ bubbles underneath, not the wallpaper bubbling, but the paint underneath expanding and releasing from the Sheetrock.

All of the other walls in this two-room bathroom were fine. As it turned out, when there was wallpaper on this wall previously, there was a seam that did this exact same thing. During renovation earlier this year, it was discovered that a pipe inside the wall had a leak. That, or possibly a leak in the roof, most likely have much to do with the wallpaper problem.

What’s hard to understand, though, is why this happened again, after the leaky pipe has been fixed. It leads one to think that the problem is in the Sheetrock. But, once Sheetrock is dry, it’s dry, right? So it’s hard to understand why the paint would delaminate from the wall.

This is an unfortunate mess, and the homeowner now is left with trying to figure out what the problem is, and what the solution is. I am hoping they re-Sheetrock the wall, either with 1/4″ drywall over the existing wall, or, probably better (but more mess and more expense) ripping out the old Sheetrock, checking the insides of the wall for continuing leaks, and then replacing the Sheetrock with brand new.
