Determine the size and extent of the mold in your structure. The Environmental Protection Agency suggests cleaning surfaces yourself if they are 10 feet square or smaller. If mold is in a crawl space, mold remediation will cost from $2,000 to $6,000. If mold infestation is widespread, the price to remove may be $10,000 to $30,000.
Examine whether you will need a decontamination chamber, which is needed when the project is massive. This can increase the cost of project.
Take into account testing and inspection. Consider costs needs for mold testing and inspection before and after remediation.
Find the cause of the mold, which will have to be eliminated at some cost.
Add living costs if the remediation project forces you to live elsewhere, such as in a hotel or apartment.
