We believe your home should support your health.

Creating an environment where your body can rest, recharge and heal from the toxins and environmental stressors of the day is the single most important thing you can do for your health and well-being. With the EPA stating that indoor air is 2-5 times more polluted than outdoor air, new untested chemicals coming on the market every day and ever increasing electrosmog, it’s an unfortunate reality that modern homes are making people sick. It may sound a bit extreme but if there’s a mini-Chernobyl hiding in the attic, a bedroom wall or under the kitchen sink, you need to know. 

We understand your house as a whole, recognize how everything works together and know where the problems hide so you get solutions that are clear, prioritized and ready to implement. Our testing for Hidden Mold, Chemicals, Air Quality & Electromagnetic Fields are done with a measured approach to the factors that could be reducing your quality of life. After your inspection, you get an interpretation of findings and results with a follow up call to go over your report so you can ask any questions and know what to do next. You can count on us to provide the best environmental testing for you and your loved ones in Metro-Atlanta!

John Crewdson is an Indoor Environmental Professional (IEP) performing Chemical, Biological and Electrical assessments in the Metro Atlanta area. With over 30 years of experience in residential and commercial construction and inspection, he knows a thing or two about where problems hide and about fixing them. While doing forensic testing on commercial and residential buildings, he learned about sick buildings and that the industry wasn’t doing much to make the buildings better. He’s been very fortunate to study with some of the best and most seasoned IEP’s and Building Biologists in the business. He’s always had an interest in alternative health and over the years that interest moved into how our homes should support our health. Now he spends most of his time uncovering specific toxins and educating clients about how to make their homes healthier places to live.

Heather Harper is the person who makes everything happen behind the scenes (and keeps John on track). On a typical day you can find her logging samples, following up with labs, confirming appointments and the like. She’s experienced first hand how little improvements to the environment can help you feel better and understands that while it might seem like a good idea to fix everything all at the same time, it’s not always a realistic goal… over time little improvements really can make a big difference.
