Professional Service

The communication and service I received from American Radon was excellent. They voiced their concerns over a radon test I had previously had done and strongly suggested I have it tested again before committing to the expense of a mitigation service. I took their advice and performed their tests as instructed but being a little paranoid about possible fraud or some shady business practices, not having any experience with A.Radon up to that point, I decided to run another independent test at the same time. The results from both tests came back and were withing 1 point of each other which reassured me that A.Radon was acting ethically, (sorry for the doubt). I ordered the mitigation and the installer was on site on time, very polite and professional. He completed the installation quickly and instructed me when to do a follow up test. After the test was sent to the lab I received the results showing the mitigation system was doing what it was designed to do. My readings went from 47pCi/L down to .3pCi/L I would recommend American Radon LLC to anyone who needs to be tested or mitigation service performed.

Very professional, very good price

John and American Radon were very professional all the way around. They were flexible when dates needed to be changed and even the address! This made one less headache of the many we were having. I recommend John when I can.

Excellent Job!

We recently purchased a new home and the radon level tested at an 8.0 I looked around online for a good, but reasonably priced mitigation system installer. I was getting a lot of quotes around $1200 until I came across American Radon. The cost was significantly lower then other quotes. John arrived on time and did an excellent job doing the installation. He helped to pick a great place for it to where it wasn't very noticeable. I got a free test kit and the result came back at a level of 1.0 or less. Overall my experience was great and the cost is unbeatable. I highly recommend American Radon.
