Should I worry about mold from the stain?« Back to Previous Page

After the rain last month, I noticed a greenish stain growing on the wall near the window in my bedroom. It’s not too big yet, but it seems to be spreading slowly. My kids have been coughing more than usual lately, and I’m worried it might be due to mold. Can someone please advise if this is something I can handle myself or if I should call a professional?
