"Tom was in a word: Phenomenal. I scheduled an Inspection and Radon Test on HomeAdvisor. Tom reached out within minutes of my scheduling the appointment. He was extremely thorough yet timely and gave simple suggestions. The last thing he sought to do was to nickel and dime us- we truly appreciated that. He was very personable and kind. His prices we the best in the area (we shopped around) and the quality of his work speaks for itself. We've favorited him and will be giving him a ring for our next home."

"Bob from SIS is a straight shooter, provides options, clear explanations and associated costs on the necessary steps to remediate the problem. Good communication, timely and professional. Pleasantly surprised with my experience with SIS and the contractor they recommended to do the work. Easy 5-star rating, not too common these days."

Radon Detection and Reduction FAQs, answered by experts

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.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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.
