What this video covers
This clip addresses the belief that once a property has been professionally remediated, mold will not return.
Remediation removes what is there at the time. It does not change the conditions that allowed growth in the first place, so a building with an unresolved moisture source can be fully remediated and still be colonised again later.
The takeaway
Remediation and prevention are separate pieces of work. If the moisture source was never identified and corrected, treat the clean building as a starting point rather than a conclusion.
