There are always challenges when assessing a home that has mold problems--what will be done with the home’s contents, whether or not the residents will be able to stay in their home while the remediation process is under way, how long the process will take, whether there will be post-remediation testing, how long that will take, and who will do it. The most important challenge is determining where the moisture is coming from that is creating the humidity necessary for mold growth.
