Mold Inspection in Cottage Grove, MN —
RH Logging, Thermal Mapping & Defensible Reports

Individual IICRC CMI credential means a specific named person with a verifiable credential performed the inspection. In real estate, insurance, and legal contexts in Cottage Grove, MN, that matters — a company-level credential without a named credentialed individual inspector is less defensible.

Sampling bias in mold inspection occurs when air cassettes are placed only in areas that appear problematic, without outdoor comparative samples or samples from unaffected areas of the property. Without the outdoor comparison, you can't determine whether elevated indoor counts are actually elevated relative to the outdoor environment. Without samples from unaffected areas, you can't confirm that the problem is localized rather than building-wide. Our Cottage Grove, MN inspection protocol always includes outdoor comparative sampling and multiple indoor locations — including areas that appear unaffected — to produce results that mean something in context.

Spore trap (non-viable) sampling identifies mold genera under microscopy and quantifies spore concentrations — fast (24–48 hours), sufficient for most routine Cottage Grove, MN property inspections. Viable culture plates capture only live, culturable spores and grow them for species-level identification — takes 5–7 days but provides species confirmation. Viable culture is warranted when: (1) species-level confirmation is needed for health-complaint investigations; (2) insurance or legal use requires exact species documentation; or (3) Stachybotrys chartarum is specifically suspected and genus-level data from a spore trap isn't sufficient to confirm or rule out.

60–90 minutes on site, same-day lab shipment, 24–48 hours for spore trap results. Complete written report within 3–5 business days of the inspection for standard Cottage Grove, MN residential properties. Viable culture adds 5–7 business days for lab processing.

Insurance-use reports include documentation requested by adjusters — scope of contamination, moisture data, cause assessment.
