"I couldn't have asked for a better experience. I checked a few Radon companies and Certified Radon was the best. They seemed to be the most knowledgeable, had the best warranty/guarantee, and actually came in cheaper than some of the others. They brought my radon level from a mid-6 to less than 1 on the first test. If you need radon services I would highly recommend."

Radon Detection and Reduction questions, answered by experts

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.

Yes, many systems include warranties for performance. Confirm terms with your installer.

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.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.
