Microbes is a broad everyday term for microscopic biological entities, commonly including bacteria and fungi. The word does not identify a specific organism or its significance.
What this means at your property
A report that mentions microbes should explain what was observed or tested. An odor, discoloration and laboratory identification are different kinds of evidence, and they should not be presented as interchangeable findings.
What should a property owner ask about the finding?
Clarify the sample location, method and reason for the assessment. Ask how the result changes the proposed moisture or cleanup work, and keep health questions separate from the contractor’s description of building conditions.
