"They found that I was above the normal level for radon after a 48 hour test, and gave me the number for someone that would take good care of me. The guy was super" nice. My wife felt very comfortable in the house with
as our inspector. He walked me through what the results meant and told me the other services they offer. I will definitely take advantage of their expertise with other inspections I will need.

Radon reduction systems help keep radon levels at home low. The EPA says such systems can reduce radon levels up to 99 percent. (Photo courtesy of Angie's List member Benjamin S.)


Radon is a colorless, odorless gas that occurs as a decay byproduct of uranium and thorium. Radon forms naturally in the environment, and low levels can be detected in soil, rock and ground water. Homeowners that inhale radon are at risk of lung cancer and even death.

Radon Testing reviews in Saint Charles


Saint Charles Radon Mitigation Experts Provider Name Locked
(the owner) arrived and immediately showed me his radon badge. He was very helpful on inspecting the basement and explaining all the aspects of the system. He also was willing to work with me and adjusted the position and location of the system to better suit the basement. He did a very thorough job and was on location for approximately 6 hours.
Thank you for the great job

provided great, prompt service. This transaction is on an accelerated timeline and we've been nervous about completing all of the inspections in time. It also didn't help that the seller's agent suddenly became non-responsive as we were trying to coordinate these inspections.

proactively reached out directly to the seller, and performed the test, all in a shorter timeline than previously requested. The results were also delivered quickly. And, thankfully, we don't have any radon issues with this house. It's a small price to pay to know we're living in a safe home.

showed up on time to answer all of our questions and was very thorough in his explanation of what could be done. He is extremely knowledgeable and one of the nicest guys I have ever met. I would not hesitate to contact him for anything in the future

The provider is related to the realtor that represented the potential homebuyer. His inspection reported severe structural issues with the home. This enabled the potential homebuyers to walk away from the purchase. Structural engineer found no deficiencies. Not only was the quality of work poor it seems to be a question of ethics when the home inspector is related to an selling agent.
- Amy T. S.

We just moved into our newly built home and had a radon test completed with our inspection. The results were over 3 times the recommended level, so we researched companies and found

to offer the best price for the product and the warranty included. The sales rep gave a thourough estimate and the installers came right on time and completed the installation in the time that was stated.

Wonderful job, couldn't ask for better service & price. As a Realtor I deal with all sorts of Radon companies and by far I would recommend R&R the best.
- Kelly R.

I first contacted
Saint Charles Radon Mitigation Experts Provider Name Locked
in January 2014 because they list St. Cloud, MN as a service area and because the MN Department of Health listed them as a certified Minnesota Radon Contractor. This was right after MN passed legislation requiring the seller in real estate transactions to disclose to the buyer a description of radon testing, concentrations or mitigation pertaining to the property. As a short term test revealed somewhat high levels of radon at the property I decided to purchase, I contracted with

to mitigate or reduce the radon level to an acceptable level. After a March 2014 installation of the radon-reduction system in my home by
Saint Charles Radon Mitigation Experts Provider Name Locked
, several follow-up tests revealed the radon level was reduced but not to the low level guaranteed by

Saint Charles Radon Mitigation Experts Provider Name Locked
knew of the issue I simply waited for them to suggest a solution. After several months of waiting I contacted them in June and asked what they would do next and they said they would install a larger suction fan. It then took until October for the larger fan to be installed and for the radon level to be reduced to the level they guaranteed in March. So it basically took SEVEN MONTHS for them to complete the work. As a final misstep on their part, they did not provide me with a written guarantee as promised in the contract until I asked.
To be fair the installation work was neat and the radon-reduction system does work as promised. However, for the amount of money charged I did expect far better customer service and attention to detail than I received.

was very informative and was able to answer all of my questions. He took his time and included me in the inspection by showing me his findings. Email report was provided within an hour of concluding the inspections. Very professional.
