Mold removal and mold remediation are two very different things. Mold removal is the process of physically removing mold from a surface. This can be done with a variety of methods, including scraping, sanding, and using a bleach solution. Mold remediation, on the other hand, is the process of cleaning and repairing a surface that has been damaged by mold. This can involve anything from removing moldy drywall to replacing insulation.
