The company replied quickly with an initial quote. Of the three companies replying, Indoor Doctor was able to send a tech out the same day to perform inspections, testing and provide answers to my many questions. The tech was very professional, courteous, etc. Indoor Doctors provided an initial quote of $199 for the visit, which only covers the visit and inspection. They break down the separate fees for each test beyond the $199 inspection. There is a separate charge for each sample test. Mold test and allergen test from the same location are considered two tests and charged accordingly. Their pricing was competitive. Their ability to come out the same day was what sold us on Indoor Doctor.

I have no complaints with the service. I just donĂ¢ t give 5stars for anything. Respectable. Knowledgeable. Answered every inane question my significant other could come up with to the point she was satisfied (I also answered those same questions but she would listen to me which is why we hired them)

"Hi Christian, thank you for your feedback. We understand you wanted to give us a 5-star review, but the four stars were for Angies, not IndoorDoctor. We're working on upgrading the rating but are glad we could identify a hazardous mold issue in your home. Please let us know how we can help you further."

I highly recommend IndoorDoctor! Everyone I have worked with has been knowledgeable and professional. They were fantastic from scheduling to home visit and testing to report delivery and follow up. Sean was thorough in his evaluation and provided actionable items on evaluation as well as answered any and all questions completely. I could not be happier with the service provided by IndoorDoctor and am so thankful to have them as a resource in keeping my home air clean and healthy!

outcome is satisfactory
Response from

"Thank you for hiring us to check your indoor air quality. We detected a very serious carbon monoxide issue that can cause serious adverse heath effects you were experiencing. It's important for people to realize that you may have unhealthy carbon monoxide levels in your home even if your detector is not going off. Headaches can start at 5 parts per million (ppm) and your detector may not go off until 150ppm! IndoorDoctor has testing equipment better than your local fire department"
