"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

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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.

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

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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.
