While it is indeed law in some states to hire a third party assessment company to perform an assessment, it is our company policy. We will not take on a project without a third party mold assessment by a licensed assessment company. While you may be able to visibly see the problem, the mold sources often extend from what the eye can see. We are doing you a disservice if we charge you to remove mold without knowing the full picture. While this may seem like an over-the-top approach with additional costs, we assure you that this is the absolute best practice; in our company the only practice. Please see our sections Mold and Mycotoxins to learn about all of the things that can be missed by the naked eye.
