"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."

"The service was for Radon Mitigation in our home that had higher than acceptable Radon levels. The work was professionally done, and care was taken to protect carpeting etc during their work. The crew updated us home owners as they did their work and asked permissions for needed modifications to the house. I would recommend this company to anyone looking for quality workmanship, congenial communication and moderate pricing."

"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."

"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 soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

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