Hey Closet, You're Looking a Little Moldy Today

Life loves to throw little curveballs at your face from time to time, doesn't it?

I figured I'd be happily chugging along with my Capturing December photo prompts, but here I've already missed a day, and it's thanks to a pretty ugly reason:

I hate you, mold.  (The strips on the floor are from our cardboard boxes that had been wet and when we went to pick them up and move them, the bottoms ripped off -- there's no telling how much mold is actually behind the walls/under the floors.

Mr. L and I were pulling Christmas decorations for the house out of our downstairs closet located in between our staircase and half bath/laundry when we came across this wonderful little surprise.  I immediately went into panic mode, but at least had enough sense to start taking pictures.  Ever since we've moved into this house, we've had issues with the plumbing and pipes.  We can't use too much water in a day or the downstairs toilet backs up and floods the bath/laundry.  It normally happens when I do more than 2-3 loads of laundry in a day, which really sucks on those days I don't plan ahead and I'm doing multiple loads prepping for a trip.  Maintenance has come out a few times to attempt to address these issues, but we were told it's because of old clay piping and the only way to actually get rid of the issue is to have a complete overhaul of the entire neighborhood's plumbing system -- AKA it's not going to go away.

We contacted maintenance last night, and of course we're told it's not an "emergency" and to call back in the morning (today).  We didn't have to call after all though -- I've already had two phone calls from maintenance since 7AM to schedule an appointment.  The supervisor and another person are going to come out tomorrow afternoon and I guess we'll see what they say then.  I don't really know what to expect in this situation.

I tell you, I'm not happy.  We've had a few issues already with this house (the biggest being the pipes backing up) and it's been bad enough that we've opted to get on a waiting list for a different neighborhood entirely, for which we'll have to pay out of our own pocket -- not just for moving expenses, but to actually move from one Forest City property to another.  I'm trying to look at the bright side in this situation.  Maybe it's enough damage that they'll see we're on the waiting list to move and get us out faster, or waive our move fee, or something.  Something good can come out of this, right??

In the meantime, I have no idea what to do about it except hide upstairs with the puppies, haha.  I know very little about mold, much less the kinds of mold that exist and which are bad, etc., so I have no idea if we should be leaving the house and staying elsewhere for the night or what.  I'm honestly really worried about it, but I'm trying my best not to because I know what happens will happen and I can't do much to change it at this point.

Have you dealt with mold issues, whether in military housing or in your own house?  How did you deal with it, and was it ever solved completely?
