What Qualifies as a Mold Emergency?
Not every mold discovery requires emergency dispatch — but these situations do:
- Visible Stachybotrys (black mold) — especially after a recent water event
- Active water intrusion — burst pipe, active snowmelt seepage, ice dam water currently entering the home
- HVAC mold — mold discovered in air handlers or ductwork actively circulating spores through the home
- Household members with severe respiratory symptoms or compromised immune systems
- Real estate deadlines — mold discovered days before a closing or move-in
- School, daycare, or commercial occupancy situations requiring immediate action
Emergency Response Protocol
1
Immediate ContainmentPolyethylene barriers isolate the affected zone. HVAC to that zone disabled. HEPA air scrubbers deployed at negative pressure.
2
Water Source ControlActive water intrusion stopped or mitigated. Emergency water extraction performed if flooding is present.
3
Scope AssessmentThermal imaging and moisture meters assess full extent of contamination and hidden moisture.
4
RemediationAffected materials removed, structural surfaces treated, HEPA vacuumed, antimicrobial applied.
5
Structural DryingIndustrial dehumidifiers run until target moisture levels reached and documented.
6
Clearance TestingIndependent CIH air sampling confirms remediation is complete before reconstruction begins.
Denver Emergency Season Calendar
- November–February: Burst pipe season — cold snaps below 10°F are common. Crawl space and garage pipes most vulnerable.
- March–May: Snowmelt season — basement flooding peak. Window wells and foundation drain failures are primary entry points.
- December–February: Ice dam season — rapid freeze-thaw cycles at higher elevation neighborhoods cause ice dam formation.
