"All Colorado Radon Mitigation Inc did an excellent job! The gentlemen that performed the work took extra care to make sure that the routing of the PVC was done correctly and still achieve the Radon level was going to be below the 4 pCi/L level that EPA requires. They did a very good job with putting the vent in the roof correctly and making sure that no leaks would come from their work. The Radon level that I recorded prior to their work was 15-17 pCi/L and now its down .3-.4. So yes they know what they are doing and they do it very well!"

"This was the 3rd time I’ve used Axium (specifically Tim Krapfl) for home inspection. Tim is very thorough, knowledgeable, and professional! I highly recommend. Tim did the home inspection, but the services also included sewer scope and radon testing."

Radon Detection and Reduction questions, answered by experts

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.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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.
