Specialized diagnostics · D-06
Targeted surface and air quality sampling to identify active microbial growth. We document visible conditions and moisture indicators at accessible surfaces and provide independent, accredited-lab results so you have objective data on your indoor air.
Overview
Mold needs moisture to grow. Sampling tells you what is present and at what level; tracing the moisture tells you why, so the problem can be fixed rather than just cleaned.
Samples go to an independent laboratory, and results are reported alongside photos of the conditions we observed and where we found them.

Why this evaluation matters
During a standard non-invasive inspection, an inspector can only report visible mold-like substances on readily accessible surfaces—we are not permitted to peel back baseboards, lift carpet pads, or cut into finished drywall where prior water damage may have been painted over or bleached. Furthermore, microscopic airborne mold spores circulating through a home's HVAC system are completely invisible to the naked eye.
Elevated indoor mold spores (Stachybotrys, Aspergillus, Penicillium) can trigger respiratory irritation, chronic sinus issues, and allergic reactions, while professional mold remediation in a basement or attic easily costs $3,000 to $15,000+.
If a property has a history of water intrusion, basement dampness, or musty odors, non-invasive Spore-Trap air cassette sampling (and surface swab/tape-lift sampling of visible suspect areas) captures airborne particulates and compares indoor air against an outdoor control sample at an accredited laboratory—giving you objective lab data without damaging the seller's walls.

Scope
Sampling and investigation, reported together.
Accessible areas checked for visible growth and water staining.
Indoor samples compared against an outdoor control sample.
Swab or tape samples taken from suspect growth.
Moisture meter and thermal readings to locate the source.
Spore types and counts from an independent laboratory.
Plain recommendations based on the results.
Lab-verified
Lab data and located moisture sources give a remediation contractor a defined scope instead of a guess.
Indoor versus outdoor comparison
Spore types and concentrations
Moisture source photographed and located
Recommendation for each finding
When there is a musty odor, visible growth, a history of leaks or flooding, or occupants with unexplained respiratory symptoms.
Typically a few business days after sampling. We confirm the expected turnaround when you book.
