"Eric was great! Very thorough on his inspection, and even gave advice on things we didn't even think to ask about. He advised of the things that had the highest safety risk, right down to the small maintenance items like tightening screws. He recommended when to replace air filters, clean the fireplace and some optional things that could help us save money in the future. And the service didn't stop after the inspection, he continued follow-up about the radon testing, and the how to address the safety issues that needed to be fixed. He was very professional and friendly. I would definitely recommend him to friends and family."

"I was extremely impressed with the professionalism of both workmen. They listened to my concerns and we were able to come up with an alternative approach to placement of the system. They were able to provide protection of both areas of my home with one system instead of installing two separate Radon systems. The system was placed in the unfinished area of the basement leaving all my finished area untouched. They left the work space cleaner then it was when they started and made sure everything was put back in place. I highly recommend Tri State Radon and Mold, Inc."

Radon Detection and Reduction questions, answered by experts

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

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

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

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 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.
