"Stanton is the ONLY radon mitigation company in the RF Valley I would ever employ. I tried another one first and it was the epitome of who NOT to hire. After complete dissatisfaction with that guy, a noisy and very unattractive system, and one that failed the radon test at the end, I hired Stanton Engineering to remove the other failed system. Stanton was incredibly professional, know their stuff, are efficient and better priced overall, gave me a system you barely notice, is quiet and does the job. The owner and crew are friendly and answer all questions and have a work ethic that is outstanding. So if you are comparing companies, know that you can call Stanton Engineering and disregard the rest. You will be so happy you did and so wish I had used them first."

Radon Detection and Reduction FAQs, answered by experts

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.

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.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.
