"The company rep was knowledgeable and hard-working, he even worked with me to get around some technical issues before he started the install. I do wish there would have been a follow up and more education with the “how-to” of the test that I had to set up and send in to ensure that the unit is working properly. All in all, I would recommend Affordable Radon Services for radon mitigation installation."

"I couldn't be more pleased with the radon mitigation service John provided. The estimate was accurate-no surprises. He was prompt, efficient and quick- it took just over 2 hours and that's including answering all my questions (and I had a lot of questions!). John's customer service was excellent and the results have so far exceeded my expectations. I am very glad I chose RMR."

"Mike was very personable and professional, he supplied me with a radon test kit that i sent off for testing but also lended me a small device to monitor radon in real time that i could move around in different areas of the house. Results came back low and Mike was honest and explained there no need for mitigation."

"This was the 3rd time I’ve used Axium (specifically Tim Krapfl) for home inspection. Tim is very thorough, knowledgeable, and professional! I highly recommend. Tim did the home inspection, but the services also included sewer scope and radon testing."

"Bought a house and had a Radon Test done. It came back higher than the recommended EPA levels (I trust and believe in the EPA actually). Got a number of estimates and reviewed some companies. I went with SWAT Environmental as they could schedule weekends. I believe his name was Robert, he showed up on time and completed faster than expected. He answered all of my questions and was open and honest about everything. He was respectful of the property interior and exterior. Overall a great experience and I would recommend SWAT if you need Radon Mitigation."

Radon Detection and Reduction FAQs, 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 enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. 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 action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.
