Most mold inspections start with a smell, not a photograph. Microbial growth releases the musty, earthy odor people describe as wet cardboard, and in a Florida home the smell is strongest when the AC starts, when a closet opens, or when you come home after the house has been closed all day. Homes do not smell musty for no reason; the inspection's job is finding where the growth is and what is feeding it.
In the Humble area the smell first pattern has a geography: old town homes report it at floor level, where the crawl space breathes up, and Atascocita homes report it at the handler closet and the vents, where the AC's own water feeds it. The inspection order follows that geography, moisture survey first, sources named in writing, and sampling only where a file or a verification actually needs a lab's name on it.
The order matters. Moisture meters and infrared come before any sampling, because growth always sits downstream of water: a wet wall base, a sweating duct, a condensate pan, a shower pan that failed quietly. A lab report that names species without a moisture map names the passenger and misses the driver.
When in doubt, the meter is the referee: materials at normal moisture with surface mildew are a cleaning problem; materials reading wet with growth are a source problem wearing a mold costume. The written report should say which one you have, room by room.
