How to Document a Mold and Moisture Concern
Build a dated record that shows sequence, location, scale, repair history, and who said what.
Short answer
Start with evidence you can name
A useful record shows sequence and scale without pretending to be a laboratory report. Combine dated overview photos, close photos, a moisture-event timeline, repair records, measurements, written notices, and provider documents.
Safety boundary: If there is contaminated water, structural damage, an electrical hazard, unsafe access, suspected HVAC contamination, or a health concern, stop and use the appropriate qualified help. For this topic, first note invoices, messages, inspection notes, sample chain, and written scopes.
