Cost by Contamination Size
- Small (under 10 sq ft): $500–$1,500
- Moderate (10–100 sq ft): $1,500–$5,000
- Extensive (over 100 sq ft): $5,000–$30,000+
Additional Cost Factors
- Mold type: Toxigenic species require more extensive protocols
- Location: Visible surface mold costs less than hidden mold in wall cavities or HVAC systems
- Affected materials: Porous materials must be removed and replaced
- Air quality testing: $200–500 for initial assessment; $150–300 for clearance testing
Insurance Coverage for Mold
Most policies cover mold resulting from a covered sudden water damage event but exclude mold from gradual leaks, flooding, or poor maintenance. Coverage limits for mold are often capped at $1,000–$10,000 even when the cause is covered.
