Mold is more than an unsightly nuisance; it can cause serious health issues, structural damage, and reduce your property’s value. Whether it’s a small patch in your bathroom or widespread contamination in your attic or crawlspace, timely mold removal is critical.
In 2026, the average cost of mold removal ranges from $1,500 to $6,000, depending on factors like mold type, location, extent of mold damage, infestation, and property size. These are estimated prices, and your final bill may vary. Bayco Builders & Restoration has prepared this complete guide to help you understand mold remediation costs and what affects them.
Mold Remediation Costs in 2026: Factors and Estimates
Professional mold removal costs vary based on several factors:
1. Extent of Infestation
The size of the affected area is one of the most important determinants of cost.
| Infestation Level | Estimated Cost (2026) |
|---|---|
| Localized Damage | $500–$1,500 |
| Average Damage | $1,500–$6,000 |
| Large-Scale Damage | $15,000–$30,000+ |
Small areas may be treated quickly with minimal equipment, while widespread contamination requires extensive cleanup and structural repairs.
2. Location of Mold
Where mold grows affects accessibility and remediation cost.
| Location | Estimated Cost Range |
|---|---|
| Attic | $1,000–$4,000 |
| Basement | $500–$3,000 |
| Crawlspace | $500–$2,000 |
| HVAC System | $2,000–$6,000 |
| Wall Cavities | $1,000–$20,000 |
Hard-to-reach areas like attics and crawlspaces increase labor time and equipment needs.
3. Type of Mold
Some mold types are more hazardous and costly to remove:
- Black mold (Stachybotrys): Toxic, requires specialized containment, higher cost
- Green or white mold: Less toxic, lower removal cost
- Surface mildew: Minimal cost if addressed early
4. Contractor Experience and Reputation
The team you hire significantly affects pricing:
- Newer teams with limited reviews may charge lower rates
- Experienced, licensed contractors with professional equipment and strong reviews often charge more but provide safer, more reliable service, especially for mold removal, water damage restoration, or sewage damage repair.
5. Mold Inspection Fees
Before remediation, professionals perform a detailed inspection and testing.
- Estimated inspection cost (2026): $300–$1,000
This step identifies mold type, damage severity, and necessary remediation steps.
6. Emergency Mold Removal
Toxic or structural mold may require immediate remediation. Emergency services can add hundreds or even thousands of dollars to the total cost.
7. Property Type
- Residential mold removal: $1,500–$6,000
- Commercial mold remediation: $10,000–$60,000
Larger properties require more labor, stricter compliance with safety codes, and specialized equipment.
8. Material Affected
The type of material impacted by mold also influences costs:
- Drywall, insulation, or hardwood flooring may need partial or full replacement
- Personal items like clothing or toys are easier and cheaper to clean
Preventing Mold After Remediation
After professional mold removal:
- Fix leaks and improve ventilation
- Use dehumidifiers in damp areas
- Perform routine inspections to catch growth early
- Address water damage promptly
Conclusion
In 2026, mold removal costs can range from $1,500 to $10,000+, depending on the extent of infestation, mold type, property size, contractor, and damaged materials. Early detection and professional remediation can prevent health hazards and costly repairs.
