"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."

"Our radon system fan needed to be replaced and we were able to get that done the day after I talked to this company. Very quick and courteous service and didn't cost as much as we were anticipating."

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).

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.

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.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Mitigation reduces radon levels, protecting your health and complying with safety standards.
