Documentation is one of the most valuable parts of a DIY mold assessment. Even if you’re not planning to submit a formal report, recording what you find—consistently and clearly—helps track changes over time and supports future decisions about remediation, repairs, or testing.

For each room or area inspected, note:

• Date and time of inspection
• General location (e.g., “Master bedroom – east wall”)
• Environmental readings: RH, temperature, any elevated moisture readings
• Visual observations: stains, damage, odors, condensation, mold
• Tools used (e.g., UV light, borescope, moisture meter)

Use a digital log, spreadsheet, or paper notebook—whichever is easiest for you to maintain. Label your photos clearly, and if possible, embed them into your notes or link them with file names like “LivingRoom_NW_Ceiling_Stain.jpg.” Consistency matters more than perfection.

The goal isn’t to write a report that sounds professional—it’s to create a clear, honest record of what you saw, felt, and measured. This is especially helpful if someone else (like a doctor, contractor, or mold assessor) needs to understand your findings later.
