"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."

Radon Detection and Reduction questions, answered by experts

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

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

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

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.
