It is important to ensure your inspector is qualified. I’ve worked with and against many who couldn’t find obvious visible damage and fungal growth that was literally right in front of them. Additionally some inspectors do not have the experience to interpret lab results and apply them to the conditions present, including sensitivity of the persons exposed. Ask your inspector how long they’ve been in the industry, how long they’ve been interpreting results and what type of training they’ve undertaken. Continuing education is also important.
