Installation of radon fan

This company was very easy to work with and had the most reasonable prices based on other companies we looked at. They were friendly, quick and did exactly what they said they would. Our fan seems to be working great and they made it very easy to re-test for radon levels once the fan was installed (ie: provided us with a test and prepaid envelope to send it).

Made this easy! Cares about details.

John and Tricia made mitigating radon levels in our new home easy. From the first to the last, I was treated friendly and provided clear information about processes and costs...there were no surprises. John showed up as scheduled, walked through options, explained what he would be doing and went to work. John also offered ways to visually minimize the pipe including by painting it to match the rock and siding. I have recommended American Radon LLC to friends. They provide quality work with exceptional customer service.

Short term is not long enough

After getting my test results for a five day test, the result of 740 indicated I might have a problem even though 400 is the cut off. They said that several variable might have caused a false result so I should retest for a longer term. Why not do the longer term initially?

Great Job!

Exceptional service, price and attention to detail. Our initial Radon level was 22.9--post mitigation was 0.6! No hesitation in recommending American Radon, LLC to others.

Super happy

We were given an excellent pricing by this company and given excellent service. John was prompt and got the job done in the amount of time estimated. The job was clean and well done and he answered any and all questions I had. We were also given a radon test kit (bought and paid for already) to make sure the system was working properly after being installed. Highly recommend.
