Mold Inspection in Lewisville, TX —
RH Logging, Thermal Mapping & Defensible Reports

IICRC Certified Mold Inspector (CMI) is a specific credential from the Institute of Inspection, Cleaning and Restoration Certification that requires documented training hours, passing a written examination, and ongoing continuing education. It's a verifiable individual credential — not a company-level certification that a business displays while sending uncredentialed staff to conduct inspections. In Lewisville, TX real estate and legal contexts, having the inspector's individual credential on the report matters because it gives the report a named, verifiable human author who can be contacted for testimony or clarification.

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 Lewisville, TX 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 Lewisville, TX 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 Lewisville, TX residential properties. Viable culture adds 5–7 business days for lab processing.

Report format is matched to use case at booking. Real estate, insurance, health complaint, legal — each format includes the specific elements that make the report usable for that purpose without additional translation or reformatting.
