If you are purchasing the home and are truly concerned about mold levels, contact a home inspector. Mold damage can be the result of a number of deeper issues, and mold remediation companies may not be completely impartial. When selling in the future, you may have to label mold issues if you choose to fill out a disclosure, which is customary in resales. Best of luck!
