Review what was actually treated
Compare the original assessment map with the completed work. Ask whether stored contents, concealed areas, and relevant system components were included or excluded. A gap in scope is different from a treatment that was performed but did not achieve its agreed result.
Ask for a revised explanation
- What remaining source is suspected, and what evidence supports it?
- Is more access or a different material decision needed?
- How will the next result be reviewed and documented?
Coordinate any additional removal
Have the specialist identify the materials involved before the reconstruction team opens or replaces them. Record costs and authorizations for the revised work. Avoid masking fragrances or owner-directed chemical treatments; odor management needs an assessment, not an assumption that another treatment cycle will solve it.
