It depends on where it is (i.e. visible surface mold on a wall that is not wet inside or mold growing inside a wet wall), and how much mold is present (i.e. roof and plumbing leaks or floods can result in extensive water damage and support a lot of mold growth).
Best case scenario – The spore counts are not too elevated and the mold is visible on building materials that have dried out. Getting rid of the mold will not involve invasive procedures and may only require limited containment because the growth is confined to a small area.
Second scenario – Highly elevated levels of mold spores are present and wet building materials are present. In this case mold remediation will require more invasive procedures like removing drywall, plaster, or other building materials. It may include contents decontamination, and extensive containment procedures to prevent cross-contamination to other areas of the home.
