Carl was prompt, professional, and a wealth of knowledge. The musty smell in our kitchen was tested inside and out. Carl also examined different areas to try & target our problem. We feel Carl went above and beyond in explaining the situation and suggesting solutions. Since my husband and I are older seniors, we truly appreciate Carl's honesty and knowledge. Carl is highly recommended by us.

We live in our RV, our pipe froze and caused a water leak inside, we were quite concerned about mold since our floors & carpets got wet. Carl traveled a long way to accommodate us, he was personable and extremely knowledgeable. Fortunately our tests came pack negative. Highly recommend this company & Carl.

Carl was great. Took the time to investigate potential issues and did not try to sell us any services we did not need. Great customer care! I would highly recommend Carl and would definitely hire him again.

Just talked about himself the whole time he was here. Charged $275.00 for an indoor and outdoor mold spore test. The outside test was taken in front of our door, far from where the main problem was, in back yard. Tests were e-mailed after having to call because of mix up with Fed-Ex. Tests were not explained. I have an indoor and outdoor air mold test that I had to print out and don't understand. When I called him to ask why the only outdoor air test that was taken was taken in the front of my house, he replied "That's how we do it."

Carl was awesome - squeezed us in at the end of a long day but didn't rush the work. Explained as he went along and was really fantastic!

Carl performed a very thorough inspection of my home for sources that might contribute to indoor air quality issues, and used a variety of equipment in front of me to display that numerous harmful compounds were not present, while explaining how the equipment worked and why it was displaying different readings in different areas. He also had a plethora of useful advice on addressing odor issues in the room that was the main concern, and in general was very friendly and easy to work with. I'd use him again in a heartbeat.
