Hi Brandy,
You would really need to call a mold remediation company to get an estimate and to determine the extent of the damage. There are approximately 400,000 types of mold, of which less than 100,000 have been named. Approximately 1,000 types of mold are found indoors across America. Less than 80 molds are suspected of causing some form of illness, and only a few of them are considered toxic. I don't want you to think because of this you have nothing to worry about, because 80 is still a high number. Since the moisture in bathroom is coming from inside the bathroom and not behind the walls, it is most likely contained on the inside of the bathroom just on surfaces where you can see it. Try spraying the areas with bleach which will kill the mold but if that doesn't work after a couple applications, you really should call a professional. I don't know what they would charge, but it isn't cheap. They should give you a free onsite estimate though. I would also get that fan fixed quickly and get that air moving again in there. Hope that helps :)

I'm an adult and I'm concerned about the mold in the bathroom of my mom's house that I also live in. It's black mold, but sometimes there is orange stuff too. Some of the tiles in the shower have fallen off, and the mold has spread to the drywall behind it.

When my parents bought the house, the bathroom originally had a window in it and a fan in the ceiling. They filled in the wall so there's no longer a window. And at some point over the years the fan in the ceiling broke so now there is little ventilation.

What needs to be done to clean up the mold problem and what is the cost estimate? Would a whole shower/bathroom renovation be necessary?

I am concerned about the health effects from the mold and I've tried talking to my mom about it and she just wants to pretend it doesn't exist and not even talk about it.

Due to my own circumstances, I am unable to afford to move out. My mom doesn't have a lot of money either so I'm wondering if the situation is hopeless.
