"I have been with Mastery for four years and since day one, Indoor Environmental Concepts has been our ’go to’ for making sure our two dozen schools are safe for both students and staff.  They are more than experts in one area but offer turnkey solutions, asbestos inspections, lead in water and paint testing, and assistance with opening previously decommissioned spaces. Since COVID, the expert team has provided comprehensive air sampling and ventilation monitoring services. Knowledge and experience are just part of the package. IEC is reliable, highly attentive and far more than a vendor. They are a trusted partner."

Rob from Indoor Environmental Concepts replied to my inquiry immediately and was very emphatetic to my situation. He came out the next day and explained everything thoroughly. When the results were positive he advocated a contractor and came out with him to my house. Rob sent me a full report and I was very happy with his compassion and his help.

We hired IEC after doing some demolition work and having concerns that asbestos may have been in the materials we removed. Rob returned my call immediately on a Sunday afternoon, and he was able to calm my fears. He even gave me some tips for things I could do to safely clean everything in the meantime before he came out to take samples to the lab to be tested. When he came out to our house he was professional, thorough, and knowledgeable. We discussed what samples to take and he explained the process in detail. When he left he secured the area to limit the amount of dust and again went over things I can do to safely clean up and limit exposure, all while calming my nerves! Fortunately, a few days later immediately after he received the results from the lab, he let us know that there were no asbestos fibers detected! The relief alone was worth every penny! I highly recommend IEC and can't say enough good things about my experience with them. IEC is professional, thorough, knowledgeable, and their cost is reasonable and worth every penny. Thank you, Rob and IEC!
