I have a first-floor wall that has some water damage in one of the corners. The cause was apparently a clogged gutter, which was spraying rain water directly onto the exterior of the wall. The clogged gutter is fixed but now I would like to repair the damaged interior paint.
My first idea was to simply remove the damaged paint, prime, and repaint with a color-matched paint color. However, I'm worried about whether more extensive work might be necessary, since I came upon some other threads that mentioned also replacing the drywall. (I'm a complete DIY novice, BTW.) Is this a case where I'd be fine with just repainting, or is there more to it than that?
Here's a picture of the damage. The house was built in 1994 but I believe the paint is relatively new...not entirely sure though. Any advice would be greatly appreciated.
