On behalf of my husband and family, I want to say that I can’t thank you enough for your persistence in identifying several indoor contaminants that went unnoticed for many years in our home. Without realizing it, they were contributing to the sickness of our son. You went over and above what was expected during a routine furnace inspection. And with the remediation solutions you offered, our indoor air is noticeably cleaner and our son has all but lost his chronic asthma symptoms. I have given your contact information to our physician and will continue to forward your name to others.
