At a high level, nearly all mold remediation includes physical removal of affected materials and disinfection of the affected areas. Below are the basic methods for disinfecting.
Ultra-violet (UV) light
Dry Fogging - An excellent mold removal company for this is www.floridapuremaintenance.com
Ozone
Scrubbing
Misting
These disinfection methods don't include phyiscal removal, which is a byproduct of demolition.  Demoltion may or may not be necessary.  Our experience is that you minimize demolition the most when you use a dry fog protocol.
