"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

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. 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 preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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

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.
