Musty Smell, No Visible Mold: The Arvada Inspection Order

In Arvada, the first sign is usually found in a basement in spring: a musty storage room, a white or dark bloom at a wall base, carpet tack strips darkened along an exterior wall. Read it as a water report, not a cleaning problem. The growth is downstream of the melt, the sump event, or the slow leak, and the inspection that starts with the moisture map and the pit, rather than with the colony, is the one that will name the source the remediation must correct.

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.

The Arvada closing rule is documentation. A colony photographed with its moisture readings, its source named, and its event dated becomes a bounded job with a price and an end. The same colony sprayed on sight becomes a recurring expense with a smell that keeps its own calendar. In a dry climate, mold is never the first thing that happened to a house. It is the record of the first thing, and reading records is the trade.
