We run the inspection the way a lab would, not the way a hardware-store kit does. Air sampling and surface sampling are the same methods that hold up for insurance claims and real estate transactions, unlike a spore-count kit that gives you a number with nothing to measure it against.
Air samples measure spore concentration and species indoors, then compare that number against an outdoor sample taken the same day. That comparison is what tells you whether your indoor air is genuinely worse than what’s outside, since mold spores are always floating around outdoors no matter where you live. Surface samples identify what species is growing on a specific material where we suspect active growth. In Irvine’s newer tract homes, HVAC ducting frequently runs straight through the attic, and condensation on that ductwork is one of the specific spots we check, a source nobody spots without climbing up there and looking for it specifically. Every sample goes to an accredited third-party lab, not to us, and the report that comes back to you spells out exactly what’s growing and how your indoor air compares to what’s outside.
