Confirmed Black Mold in Greeley, CO:
Type III Containment & Removal

Color is not species confirmation. We surface-sample and lab-confirm the species before applying the Type III Stachybotrys protocol. Dark mold in your Greeley property may or may not be Stachybotrys — accredited lab analysis answers that question definitively.

Trichothecene mycotoxins survive in dead Stachybotrys cells. Biocide treatment kills the living mold but leaves mycotoxin-containing material in place. IICRC S520 specifies complete physical removal of all Stachybotrys-contaminated porous materials — not in-place treatment. Contractors who offer in-place biocide treatment for confirmed Stachybotrys aren't following the industry protocol.

For confirmed Stachybotrys removal, we strongly recommend temporary relocation of occupants — particularly those with respiratory conditions, children, and elderly residents — for the duration of the removal phase and until IH clearance sampling confirms acceptable post-removal conditions. Type III containment significantly limits cross-contamination, but for mycotoxin-producing mold, we consider temporary relocation the conservative and appropriate approach.

Post-removal confirmation uses independent IH-collected air samples from the previously contaminated zone and outdoor comparative samples — analyzed by an accredited lab. Acceptable post-clearance parameters mean indoor Stachybotrys spore counts are at or below outdoor baseline levels in the treated zone. The written IH clearance report documents this comparison. We don't self-certify clearance — the independent IH provides the objective confirmation.

Stachybotrys chartarum requires consistently wet cellulosic material to establish — not just high humidity, but material that has been continuously wet for an extended period. Common sources in Greeley, CO properties include: chronic roof leaks that saturate the drywall or insulation below; long-term plumbing leaks inside wall assemblies; slab leaks that maintain wet conditions on floor material above; basement flooding that isn't completely dried within 48–72 hours; and HVAC condensate leaks onto drywall or ceiling tile. Its presence is always evidence of a sustained moisture source, not just a humidity problem.
