"The radon mitigation unit was installed quickly and I was impressed with the crew. After installation, I found my refrigerator was not working. Called an electrician who had to fix the outlet which blew out due to the installation of the mitigating unit. Also, the electrician told me that the unit was installed with the wrong gauge of wiring to the unit and had to replace it to make it up to code. Although Matt repaid me for my out of pocket fixes to his work, he never did come back and finish the final phase which was to test the mitigation unit although contacted on several occasions. I will say this, nice guy, but I think he is so busy he does not know which project to tackle next and forgets that he still has some others left hanging."

Radon Detection and Reduction questions, answered by experts

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional. 

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Yes, if high levels are detected, professionals can provide solutions for radon reduction.

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.
