"George was not only on time but stuck around while we waited to here back from the my realtor (who had to call the sellers' realtor who then needed to call the seller) to ask questions and get answers before the inspection could really be started. He was personable, knowledgeable and very, very, very thorough. His report was finished in less than one business day; included detailed remarks, recommendations for action and pictures to back everything up. George's prices are in line with the other quotes that I got and he was able to do the radon testing and has an insect inspection company that he works with; all products needed are right there with one call to Highland Home Inspectors!!! He truly couldn't have made this process any easier!"

Radon Detection and Reduction FAQs, answered by experts

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

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

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.

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.
