"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."

"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!"

"We recently had a radon mitigation system installed. When they ran the pipe for the radon fan out the side of the house they uncovered a pipe with asbestos that had previously been unreachable. I called AAA concerned and they were able to send someone to look at it the same day and completed the work that same week (I realize that might not always be possible). A small, quick job for $250, so I was very grateful they were able to squeeze us in and willing to take on the project. The first company I called was booked until April. I will call AAA first from here on on. They did great work and were all friendly and helpful."

Radon Detection and Reduction FAQs, answered by experts

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.
