"The company rep was knowledgeable and hard-working, he even worked with me to get around some technical issues before he started the install. I do wish there would have been a follow up and more education with the “how-to” of the test that I had to set up and send in to ensure that the unit is working properly. All in all, I would recommend Affordable Radon Services for radon mitigation installation."

"The cost was lower than I expected, the work was done in a few hours, the overall system looks good and was placed in a location that does not detract from the external look of the house. The radon levels seem to have gone down based on my long term radon meter, but this result is pending the official test using a short term test kit."

"My new house's radon test came in high enough for the inspector to flag it. After moving in, I called up this company and got a hold of Darren. Quick and easy process. He came out for an estimate within a few days, then again 2 weeks later to install the system in an afternoon. He even painted the vent to match the siding, no extra cost (though I did provide the paint/supplies)! Price was very reasonable. I high recommend these guys!"

"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."

"Very professional, courteous, and knowledgeable. They didn't oversell me and corrected the issues I was having with persistence and creativity. They got things up and running again with the least amount of work necessary. I highly recommend Rocky Mountain Radon."

Radon Detection and Reduction questions, answered by experts

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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

Installation typically takes 1-2 days, depending on the system and property layout.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.
