"I live in Florida. I hired Radon Technology to install a system in a home that weâ re selling in Ohio. Jourdan answered all my questions via email or over the phone. Radon Technology found a solution when another company claimed, â no way!â Radon Technology warrants the systemâ s performance and that warranty is transferable, which is perfect for me. Did I say that the price they quoted was surprisingly affordable? Had I known that I had had a radon issue, then I would have installed this system sooner."

"I was very pleased with Kevin Leonard.  He was very thorough and I was really impressed that he was over detailed versus under detailed.  I appreciated having all that extra information that I wouldn't have expected.  I got him off Angie's List.  His price was very fair."

Radon Detection and Reduction FAQs, answered by experts

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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.

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.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.
