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.
But the removal of a mother raccoon with young from the attic, with proper damage and exclusion repairs and attic cleanup can often cost $400 or more. Large bat control projects with complete sealing of all entry points in a building might be $1000 or more. But a good company should be able to give you an idea, and a price for a service and inspection and trap setup. Beware companies that offer a free inspection.
