Athelon Enterprises

The company is certified to perform radon abatement - not all companies are. The owner gave us detailed information regarding: his company, our options (including diagrams), results we could expect and what other customers have experienced. The work was completed in about 1/2 day by a crew of 3 (including the owner). The owner kept us informed from the moment he walked into the house. The house interior was protected and the crew cleaned up after the work was done. (Actually, things looked better after the installation than before they arrived.) The price was very reasonable; the results were excellent. Radon level now down to 0.3 or so.

Our first radon result was 10.4, which was tested by another local company. We ordered a different test (a link on Athelon's website) to confirm the number, which was 7.7 (U.S. EPA acceptable level for indoor radon is <4.0 pCi/L). We had 3 companies review our situation and provide quotes. Athelon's quote was in the middle, about $100 more which was negligible. Dan Hylland was the only one who suggested an interior route could be an option through a closet, into the attic, and through the roof (vs venting it out at essentially ground level and then running the pipe up the side of the house and 18" above the roof, which would be an eyesore). However, on the day of installation, there were a ton of obstacles that prevented them from starting the internal route right away. But Dan was super thorough and did his due diligence to make the internal route work, which was totally worth it so we don't have a 4" pipe jetting out the side of our house and upward 18" beyond the roof. Athelon did a fantastic job and I would recommend them in a heartbeat.

Outstanding! Did a great job of routing piping through a difficult pathway in order to minimize the pipe showing in living spaces. Very quick. Communicated very well. Very knowledgeable. Cleaned up afterword. Great rates.

We are selling our home and the buyer's home inspection turned up an average radon level of 7.8.  Our home was built in NW Rochester, MN in 1992.
We contacted Athelon and Dan replied right away.  He gave us a verbal estimate and then came out to walk the home and give us a written estimate.  I scheduled the service, which they were able to fit in about a week and a half later.
Dan was always prompt to all 3 appointments (estimate, install job & follow-up testing).
Installation day went well.  They showed up at 8:00 AM and were done by about 1:30.  With fitting the system through a closet, through the floor joists, out to the garage, up the wall through some existing shelves, into the ceiling and out the roof, that seemed like a fairly short time to complete the whole project.
Dan discussed his quality of supplies: schedule 40 PVC, fan system, etc, etc.
The post-install testing came back at 0.7, which is well below the EPA level of 4.0.
I was impressed with the work, quality, speed & clean-up.  Best of all, the testing results!

Extremely professional from start to finish.  Highly recommended.

Great experience with Dan from Athelon.  I purchased a home with radon levels around 17 pCi/L.  Dan explained my options and his recommendation.  He installed an active mitigation system attached to the drain tile and sump pit in the basement.  The exhaust pipe routes up through the garage, and includes a pressure gauge on the pipe so I can quickly verify that the system is running.  The quality of his work is excellent, and the system is unobtrusive and looks as good as a radon system can look.  In the end, the system reduced radon levels to 0.7 pCi/L, well below the EPA's recommendation.  Very satisfied--I highly recommend him!

Dan did the testing and installation, and was always extremely professional and friendly. He was punctual, speedy, and conscientious. He and Mike (also professional and friendly) installed the system beautifully and left the work area cleaner than they found it. This was a very positive experience and they got the radon level down to extremely safe levels (down from extremely unsafe levels!). Don't let Dan's youth fool you...he knows what he's doing. I highly recommend this company!

Service, quality, price & installation went great.  Very professional and knowledgeable about the radon system.  He measured the radon levels after installation & met the targets he promised.

He swept the garage after leaving!  Would definitely recommend him to anyone in the greater Rochester, MN area.

Please learn from my earlier mistakes. In 2003 I hired a certified radon mitigation contractor after learning the radon level in my home tested at 36 pCi/L. The contractor I hired in in 2003 did not perform any diagnostic tests to see what kind of results could be expected from the installation of his system. After installing that system my radon level was cut in half, but it was still far in excess of the recommended level of 4 pCi/L or less. In 2007 I hired a different contractor to offer a solution to lower my level. The second contractor I hired (who, like the first, was listed on the Minnesota Dept of Health list of certified mitigators) came in and provided no diagnostic tests, but instead replaced my first fan with a larger unit with the hope that it would do a better job of providing sub-slab suction. The follow up test revealed my numbers had improved, but still were not acceptable. After contacting Dan Hylland at Athelon Enterprises I immediately knew this contractor was different. Dan's first recommendation was to drill a series of test holes to determine the limits of my current system. The testing provided by Athelon determined that my existing system only covered about half of my basement slab. After testing Athelon located the best available point for a second suction point, installed it and re-tested. The tests indicated that negative pressure was seen at all test holes indicating that the results of my next test should be positive. The work provided by Dan was professional, timely, and neat with great care taken to protect my home's interior floors and stairs from the many trips back and forth from his van. Not only did Athelon improve my radon reduction system he fixed a crooked exhaust pipe on my roof that was installed by my second "certified" contractor. Don't even consider a contractor who can't provide you with diagnostics, and if you are looking for a fast, friendly, cost effective installer Athelon Enterprises should be your first and only call.
