Can anyone help? I have a drip on the inside of an exterior wall at the front of my house. It's very faint, brownish in color. and a little sticky. I want to do some repainting but need to fix this issue first. The wall that has this problem has a gutter that I try to keep clean but as there are a number of trees nearby the gutters do fill up. There is also the same problem to a lesser degree on the bottom edge of a window located about in the middle of the same wall. Is this simply a damming issue or something more?
Any thoughts about how I can a properly correct this would be appreciated!
