"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

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

Installation typically takes 1-2 days, depending on the system and property layout.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.
