Remediation of mold contamination either by cleaning or removal of affected building material is necessary to assure a healthy environment. Mold is not a hazardous material like asbestos, but it is a health risk to persons and should be remediated accordingly.
You will find that the cost to remediate mold in an average home depends upon eliminating the source of moisture, the extent of contamination, the amount of affected material, the difficulty of material cleaning or removal, the construction details of the home, and the labor rate.
