How much does it cost to remove mold per square foot?

Thumbtack Editors

Mold remediation can be hazardous to the health. DIY cleanup is possible if your health and abilities permit it, but the Environmental Protection Agency recommends hiring a professional if your mold infestation is 10 square feet or larger. The cost per square foot for mold remediation will vary based on where you live (regional labor rates), the size and severity of your mold infestation, and the accessibility of the mold colonies. Here are some examples of mold remediation average costs per square foot:

  • Basic mold remediation in attics and crawl spaces: about $2 per square foot.
  • Mold remediation involving demolition: about $4 to $6 per square foot.
  • Mold treatment of 15 square feet in an accessible area with a less aggressive type of mold: $3,400.
    • Price includes mold inspection costs.
  • Mold treatment of 27 square feet inside an HVAC system requiring a higher level of chemicals and processes: $9,500.
    • Price includes mold inspection costs.
