"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."

"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."

"Jason was great! He was very easy to work with and did great work! The radon mitigation system looks like a natural extension to the house that was added during initial construction. Jason also offers a great warranty which made us feel more comfortable in selecting his services. Make sure to ask to see the pics of him shredding the backcountry!"

"BIG shout out to North Point Radon! We had to re-do some radon mitigation on the house so we could start working on framing in the basement and they came in and did an incredible job. The pressure from the pump (or however you say it) went up from 1.1 to 1.25, so they filled in a bunch of spaces that weren't sealed up properly and cleaned everything up so our contractor can start framing. No big chunks of puffy foam - everything is sealed cleanly and nice and tight now (obvious from the reading on the pressure). Fast, affordable, effective, and we retested the basement and it came at less than 1%. Seriously good people. I would call them if you need any radon stuff (testing, mitigation, etc.) taken care of."

"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."

Radon Detection and Reduction FAQs, answered by experts

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

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).

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

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.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.
