Look for a provider with certified indoor environmental consultants (CIEC or similar) who use borescopes to see inside walls and DNA-based lab analysis to identify specific mold species. This is critical for assessing risk, as only some types produce mycotoxins harmful to children. A reputable inspector will provide a comprehensive report with the species identified, spore count levels, and a clear remediation protocol—not just a simple pass/fail. They should also investigate the AC system as a potential amplification site.

The most credible companies are transparent about their methodology and can explain the science behind their findings. You can verify their credentials by asking for their consultant’s certifications and ensuring their final report includes detailed lab results from an accredited microbiology laboratory.
