"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 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.

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.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

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.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.
