"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."

"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."

"Justin was awesome. He seriously went above and beyond to explain things to me throughout the inspection. He was extremely thorough and he knows his stuff. He treated the inspection like he was inspecting his own home. He even took the time to show and explain how to fix a few minor things that were broken. I HIGHLY recommend using JJ Inspection. There were a few things I forgot to ask him to look at during the inspection and he offered to double check them when he went back to pick up the radon test."

Radon Detection and Reduction FAQs, answered by experts

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.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.
