"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."

"I think it’s supposed to say global industries? Alex was a big help getting our radon installed he seems like he knows what he’s doing! He did say he would send an invoice though but hasn’t yet. Other than that all good. We are waiting for the test kit in the mail to ensure the system is working as expected!"

"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."

"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 questions, answered by experts

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced 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.
