Mold Testing
across LA.
Mold testing answers a defined environmental question after visual and moisture findings are reviewed. Air, surface, and dust samples are collected using documented methods and sent to laboratory partners. Air data is considered with collection conditions and an outdoor comparison when the protocol calls for one; surface and dust results are interpreted with the building evidence rather than as a stand-alone pass/fail result.

Surface Testing
Direct collection from suspect surfaces for genus identification and viability.
Swab Testing
Targeted collection from textured or difficult-to-tape-lift surfaces.
Tape Lift Testing
Standard direct-collection method for visible suspected microbial growth.
ERMI Testing
Environmental Relative Moldiness Index DNA-based dust analysis across 36 mold species.
HERTSMI Testing
