Remediation costs vary depending on how much and where mold exists. Figure on: 1  $500 to $4,000 to remove mold from crawlspaces only.  $2,000 to $6,000 to remove mold from ducts, crawl spaces, walls, and attics.
Typical costs: If the mold is confined to a surface area of no more than 10 square feet (about 3-feet-by-3-feet), the EPA suggests you can remove it yourself by scrubbing hard surfaces with detergent and water, then drying.
