Mold Air Quality Testing · California
What do the numbers in a mold testing report mean?
Short answer
Mold reports compare indoor spore counts to outdoor 'baseline' samples. A significantly higher indoor count or the presence of 'marker' molds like Stachybotrys indicates an abnormal fungal ecology that needs to be addressed.
ClearPoint Environmental reports provide a species-by-species breakdown. We look for elevated levels of common molds like Penicillium/Aspergillus and rare, water-damage indicators. The report will explain if the levels found are typical for a California home or if they suggest active growth. We provide plain-English summaries so you don't have to be a scientist to understand if your air is safe to breathe or if remediation is necessary.
