"We just recently purchased our first home and had discovered pretty high levels of radon when doing the home inspection. I did my research and spoke with several other companies before deciding to hire Affordable Radon, and I'm quite pleased with our choice! The radon mitigation system was installed by Brandon, who was very friendly, professional, and more than willing to explain everything to us about what was happening at any point in the process. Our re-test kit came back higher than we'd like (still a huge improvement from before the system was installed though), so Brandon was back out today to honor to guarantee Affordable Radon has by moving to the next phase in the mitigation process. I have been nothing but satisfied with the company, and specifically Brandon's work. We have had alot on our plates with home renovations and it is such a relief to know that we can rely on a local company to stand by their word. Looking forward to seeing our results after the next re-test, and though I hope not to have to call Brandon back out for further mitigation, I sure am happy to know that these guys are more than willing to go the extra mile to make sure my home is safe."

Radon Detection and Reduction FAQs, answered by experts

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

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.

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.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

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.
