"Scott Bacon of Certified Radon Systems, LLC is the best! If you need radon mitigation, I highly recommend Scott Bacon and Certified Radon Systems, LLC. We saw a mansion for sale in another state online and bought it. Of course, there are lots of things to fix up with the new house, including radon mitigation. Before we even set foot in the house, Scott evaluated the property and set up a mitigation plan. He worked with us remotely, so we didnâ  t have any extra costs of flying out to the new home before we were ready to move. And he installed the equipment on time and without a single problem. Scott also followed up after the install and did some testing to make sure the systems worked properly. The house is enormous, but the cost for the mitigation systems was extremely affordable. Scott Bacon and Certified Radon Systems, LLC were ultra-reliable and did a fantastic job! If you need radon mitigation, use Certified Radon Systems, LLC. Youâ  ll get excellent customer service and peace of mind knowing you are working with professionals to safeguard your home."

Radon Detection and Reduction FAQs, answered by experts

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.

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.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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