My house was built around 2000 and i have a kohler jet tub on my 2nd floor.* I got my house several years ago and never really used the tub.* I ran it and stuff but never realluly used it.* Well, it got used last night and it leaked.* The 2nd floor exterior wall where the tub sets steps out further than the first floor.* 3 sides of fhe tub are exterior walls and the front has an access panel to the piping.* The center line of the drain sets above the centerline of my 1st floor exterior 2x6 wall right above a first floor window.* Somebody was using the tub last night and i was on the first floor.* After a little, water started to drip from the top of the window trim.* I opened up the piping access and found some water.* Got it cleaned up on the 2nd floor, but my concer is possibly wet insulation in my wall.* It stoppped dripping once the tub was turned off and drained.* Do i need to worry about mold, how can i try to dry the wall cavity out without opening the wall up.* Not sure what to do.

So we've had this in our basement ever since we bought the house about 5 years ago. We did have poor grading outside the foundation and that has since been taken care of, although I don't know that to be the ultimate cause of this mold. Anyway, can I just scrub this stuff off the wall with a utility brush and then spray this mold treatment on it? I apologize if I sound dumb, or if that's an awful idea, of which, I'm lucky I checked here first. It's just that I know how the internet has a way of over-amplifying dangers and "diy" things like this. I don't want to call in a pro who will do the same thing I'm asking about. See attached pictures. By the way, can this stuff cause coughing/allergies? The furnace is about 4 feet to the left of it. I'm just thinking that folks have mold in their walls, and air ducts for decades and never know it... right? [url=http://imgur.com/a/GsKXv]Imgur: The most awesome images on the Internet[/url]
