Photos should help explain the scope
Photos matter most when they show the affected rooms, the equipment setup, and the condition of materials before and during mitigation.
A file with many photos can still be weak if the images do not connect back to the billed work or if the room coverage is incomplete.
Moisture support should match the estimate narrative
Moisture logs, maps, and monitoring notes should support the affected materials, the drying plan, and the billed duration.
If the readings are sparse, inconsistent, or disconnected from the rooms on the estimate, the reviewer may need to question how the scope was developed.
Changes in scope need a reason
Containment changes, added cleaning, demolition growth, PPE expansion, and specialty charges become easier to defend when the file shows when and why those decisions changed.
A claim packet is stronger when those changes are reflected in notes, photos, or add-on documentation instead of only appearing in the final invoice.
Use the checklist to route the file correctly
Not every gap means the estimate is wrong. Sometimes the right move is simply to ask for support before payment. Other times the lack of support changes the recommended approval path.
The value of a checklist is that it gives reviewers a repeatable way to decide whether the file is approval-ready, partially supportable, or better suited for follow-up.
