"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

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.
