Bricks, Masonry, Asphalt and Concrete - stucco and mold

My house has a stucco exterior. On one corner of the house it is covered from the ground up with black mold. It has cracked and the mold is growing into the house. From inside the house the concrete wall seems to be falling apart where the mold is. I am not sure how to get rid of the mold or fix the wall. Can some one help me?

When you say "stucco", do you mean cementious stucco or synthetic stucco?

I believe it is cementious stucco. I don't know much about stucco.

Usually, mold does not propagate on cementious stucco. If it has mold on it, you have another issue, probably a broken water line in the wall.

I know the source of the moisture. It however is not a broken pipe it is from the gutter. Their is a piece missing so the rain water runs right down the wall. I now need to know how to fix it because the mold grew through the wall into my home and the wall outside has a large crack where the mold is from the ground up.

Ok I don't know what information is needed but at the corner of my house where to sides meet there is a crack about 1/4 inch wide. It goes from the bottom of the stucco, which is the bottom of my house to the top. Surrounding the crack is black and green mold. I have tried chemicals and scraping the mold off. The mold has grown into the stucco and concrete wall so you can see it from the inside of the house, which happens to be a bedroom. On the inside of the house the paint was puffy. I tore the paint off and all of this sand and gravel fell out. It is doing that over the entire corner of the wall from the floor to the ceiling. I have removed most of the paint and sprayed the inside wall with mold killer. the wall keeps crumbleing. What can I do to fix it?

You will have to have a local proffesional out to fix it. From your description, I can not tell what the actual wall makeup is, and without that information, I can't offer much assistance. Good luck!
