If you see mold in your home, should it be tested?
Testing for mold is generally not necessary. If you can see and smell it, you have a mold problem. However, it is recommended that you do have a thorough inspection to determine the cause of the mold growth.
You may want to hire a consultant specializing in building assessments to evaluate your entire house. These specialists conduct indoor air quality (IAQ) investigations and can determine when structural issues exist that may be causing mold problems (such as ice dams, moisture, and heating and cooling complaints).
They can help you understand why mold is growing in your home and what actions you will need to take to prevent mold growth. There are also IAQ consultants and mold remediation contractors whose primary focus is mold.
