I recently bought a house. The house don't have gutter installed. So there are a lot of water pouring down at several inside corners during the heavy rain. The rain splashed on the wall. I see the brick become black around those corners. Acturally I wonder if the black marks on the brick is mold.
So I am quite nervous if there would be mold in the sheetrock beneath the wall. The wall inside the house looks no problem. What can I do in this situation?
