"All Colorado Radon tackled a particularly difficult radon mitigation that other companies refused to mitigate. They were very thorough and knowledgeable. Most of all, they were successful in reducing radon levels to well below government standards. We would use them again."

"Our radon system was making an unusual humming noise and it was driving me crazy! I found The Radon Guy here on Angi. Shortly after posting my request, Giovanni contacted me and and within a couple of hours I had the answers I needed and a testing system set up to measure levels since they hadn’t been tested in 2 years. He explained the problem and because the fan is under warranty, will be having a new one installed soon. I appreciated Giovanni’s quick response, professional demeanor, fair pricing, and extensive knowledge. Highly recommend!!!"

"I couldn't be more pleased with the radon mitigation service John provided. The estimate was accurate-no surprises. He was prompt, efficient and quick- it took just over 2 hours and that's including answering all my questions (and I had a lot of questions!). John's customer service was excellent and the results have so far exceeded my expectations. I am very glad I chose RMR."

"HOLLY THE OFFICE MANAGER IS GREAT TO WORK WITH. I HAD RECEIVED AN ESTIMATE FOR RADON MITIGATION BACK IN MARCH AND WHEN I CALLED IN DECEMBER, SHE IMMEDIATELY SAID THE QUOTE WAS STILL GOOD. JASON ADAMS DID THE INSTALL AND DID A GREAT JOB. HE WAS VERY CAREFUL AND DID VERY EXACTING WORK. I WOULD HIGHLY RECOMMEND RADON SAFETY LLC. DAVE MAHAN, LAFAYETTE, CO."

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.

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.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

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.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.
