If there is any insulation, get rid of it put in new insulation. Even go as far as replacing the vapor barrier if there is one.
Wear a respirator and use some kind of negative air machine to exaughst during this process. Also have dehumidifiers going the whole time.
You can also hire out but its costly.
My job is asbestos/lead/hazmat removal
But we do a lot of mold remediation as well. In my state you have to be certified for all of this crap, but thats pretty much what you gotta do anon. You could.
Hepa vac and bleach the walls without removing them, but if the mold has made it to the studs. It will come back again and again.
