"Jason was very helpful explaining the testing process, and possible mitigation if our Radon levels were high. Radon testing was setup and conduced quickly and our levels were in acceptable ranges, so no mitigation was required."

"they contract the subsequent test to an actual company with a digital tester instead of giving you a canister, this was included in the original quote and they'll come back for free if you don't pass"

"I recently used #1 Radon to fix my existing radon mitigation system. I called and Jesse Fuller came to look at system same-day. He had it repaired the same week. He was professional and made me feel comfortable with work and costs to replace the existing fan. I highly recommend #1 Radon and Jesse Fuller."

"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."

"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

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.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

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

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.

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.
