Original Post: cracks and bubbles in wall?
Just wondering if anyone can tell me where these cracks and paint bubbles are coming from in my basement walls? Is there something I need to fix?

That generally is a symptom of years of water vapor trying to escape from behind an old painted surface, which is acting like a vapor barrier. Without knowing anything about what the wall is made of or what is behind the wall, it's hard to make any sort of recommendation.

It looks like there's rust on the corner bead, which would be another symptom of moisture coming through the wall.
