"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."

"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

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

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.

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.

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.
