I was extremely impressed by Indoor Doctor! They are independent which means they do NOT offer remediation services and so they have no vested interest in any follow-up remediation work. Jeff, the owner, was very helpful during our initial call. They scheduled service promptly and James, who came to do the inspection, was professional and very educational about the possible sources of contamination. He was incredibly thorough and the final report had pictures as well as the laboratory findings. AND he followed up via text to make sure I had received the email report. It was less than 48 hours from the time he took the samples to when we had the very thorough report, most of which was favorable. They had concrete advice about next steps for the things that were causing air quality problems which we will implement. I cannot say enough positive things about Indoor Doctor!

Would recommend to anyone with possible mold or musty oder in their home. Sean was very thorough and educational. He wrote a report with recommendations and was available for a follow up call to clarify questions. Very helpful!

We hired Indoor Doctor after my fiancé began experiencing some unexplained health issues, and we’re so grateful we did. Sean was incredibly helpful from start to finish. He took the time to thoroughly inspect our home, explain his findings in a clear and reassuring way, and highlight potential issues we never would have noticed on our own. He was professional, knowledgeable, and insightful. 10/10 experience — I highly recommend them to anyone in need of air quality testing or peace of mind about their home environment.

Sean visited our home today and immediately treated us with professionalism, expertise and care. His thoroughness and thoughtfulness made our interaction one of the best customer service experiences we’ve had in quite some time. We can’t recommend Sean and Indoor Doctor enough.

Cannot recommend this company and services enough. The owner, Jeff, personally corresponded with me and I had a pressing issue and he was willing to be on premises early the next morning. Communication is exceptional. Every home should have the general air quality inspection Indoor Doctor provides. With more and more everyday products being made with synthetic materials, with chemicals, coupled with tight homes and little fresh air, we live in unhealthy environments. Indoor Air provides a host of testing. including mold. Sean M. visited my home and was very knowledgeable and professional. I expect results in 3 to 5 days. Climate change is also affecting our air quality. The doctor is in and ready to diagnose any issues and provide advice to get you in your way to good health again! Super experience.
