"It went great. I highly recommend them. They were a pleasure to deal with. The person that came out for the estimate answered all of my questions. The estimate was fair. The work was done on schedule and with no problem. At completion, everything was explained to me. I used their electrician which worked out fine. After completion the radon test showed that my level was now undetectable."

"Steve was very thorough and answered all of our questions. He tested things no other inspector we have had did, for example all the outlets. His report was sent to us quickly. He helped us decide which issues from the home inspection needed to be addressed right away and which could wait. He was clean and articulate. Very nice guy. Highly recommended."

"I met Ryan Amundson 2 yrs ago when my mom hired him to do a home inspection. Since then, my daughter, my son, and myself have all hired him to do home inspections on our new home purchases. He is AWESOME! Very professional! He is very thorough but still personal. Even when I interrupt him with my many questions, he is always willing to take time to explain things, show me items, and give me advise. His reports are easy to understand and always accompanied by great photos of any issues. I would highly recommend A-MAX and Ryan Amundson. You wonâ  t be sorry!"

Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. 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 preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

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

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.
