Black Mold

Lindsey asked:


I had an ice dam on my house, over the past couple of days water has been slowly trickling into my laundry room which has old plaster walls covered in wall paper and paint. The wall and the edge of the ceiling is wet and a little soft in places, and I think mold might be starting to grow, in some places the water running down the walls is orange (I don’t know why, possibly dye from the wallpaper, or something in the wood framing, the house is very old). I wanted to remodel this room eventually but I don’t have the time or money to do it right now. Is there any way to kill or prevent mold growth on and in the walls without ripping them out?

I was thinking of using a spray on the walls … but I have a feeling this is only superficial and that there could still be growth behind the plaster.

I’d just like to get some opinions.

Mandie asked:


I live in an old house (probably built around 1940) located in Connecticut. Older homes like mine usually have layers of wallpaper sealed on every inch of the house. It has been raining heavily during this summer and the rain is leaking through my window. The water gets between the wallpaper and the wall causing the wallpaper to peel. I teared off some wallpaper a few weeks ago and found this black fuzzy mold that is kind of chalky. It rained today and I teared off some more wallpaper and it looks like this mold or mildew is growing up my wall. Does anyone know what this is and should I be worried?

I am in the process of repainting my walls and I pulled some old dried wallpaper (painted over) that was peeling. Underneath I found black mold on the plaster wall. I live in a house built in 1930 so we have window air & this wall is adjacent to the window air, hence the black mold. I need to know the best way to clean it off.
