"A1 and Andrew were great. Returned my call right away, gave me a fair bid, what I should expect, and a date to come out. They called ahead of time, and did quality work. Don’t hesitate to use them. I got lucky. I found out I had lung cancer and did a radon test. Don’t hesitate to do a radon test, and use A1 if appropriate. Thanks."

"Very nice company to work with. Wayne came by within a day to do an estimate which was in line with others I checked. We had radon levels according to my AirThings Radon Detector of between 5-8 pCi/L; as we have a fairly large footprint and no drain tile they could hook into he suggested a larger fan unit just to be on the safe side. Estimate was $1400 with the larger fan and a sump seal. Wayne answered all of my questions clearly and responded to email when I had additional questions. I had to wait about 2 weeks on the install as they were fairly busy. Roger the co-owner handles the installs and he came along with an additional helper. They took about 4 hours on the job and did some nice work including some fancy snaking of the exhaust to get it above the roof line. Wayne they handles the final test and he came by about 2 weeks later to do the testing. He ran a 48 hour test that yielded an average reading of around 1.8 pCi/L - I had hoped for a bit better reading but it was well under the 4 recommended by EPA guidelines so I couldn't really complain. I noted that the AirThings detector I had gave a very similar average reading. The good news is that over time I'm seeing the average reading on my meter improving and I show a long term reading now of about 1 pCi/L and often have short term daily readings close to 1/2 of that. Overall very pleased with the work and results."

"Sam was on time for the estimate appointment that was scheduled. He was very friendly and professional. He was not pushy in any form. On the day of the scheduled service appointment he showed up ready to work and was again very friendly and easy to communicate with. He got the work done in a very reasonable amount of time and his electrician showed up on time and was the same. We will have our after mitigation radon testing done and I will update my review then."

"I contacted Radiant Radon through Angi and Jonathan responded within minutes. We spoke over the phone the next day and I was given a firm price. The work was completed within a couple of days and Jonathan was super communicative and did a great job. I have an air quality monitor and the radon level dropped from 9.0 to below 1.0 within 24 hours. Overall - awesome service, great pricing and a great guy!"

Radon Detection and Reduction FAQs, answered by experts

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.
