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 Baytown the smell first pattern has two usual addresses: the handler closet, where condensate has been feeding growth the system then distributes, and the low wall base on the slab's damp side, where gumbo ground argues upward. The inspection order checks those two first, meters in hand, and treats sampling as a filing tool rather than a discovery tool. The map that results names the source in writing, which is the only version of the finding worth paying for.
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.
