"Radon levels were over 7 at the new house we bought. Andrew installed a radon mitigation system and brought the levels down below 2.0. Andrew and co-worker were great to work with. They installed a standard system that they provided as estimate for up front. They provided 2 test kits to check the results after the work was done. When I screwed up the tests, they provided 2 more kits."

"Ron's a nice guy, knows his business and does a good job. After completion of his work he cleans up the work area before leaving. He guarantees his work and runs a radon test to assure the radon level is acceptable. Thanks Ron and thank you Home Advisor for putting the two of us together."

"Sam was on time for the estimate appointment that was scheduled. He was very friendly and professional. He was not pushy in any form. On the day of the scheduled service appointment he showed up ready to work and was again very friendly and easy to communicate with. He got the work done in a very reasonable amount of time and his electrician showed up on time and was the same. We will have our after mitigation radon testing done and I will update my review then."

Radon Detection and Reduction FAQs, answered by experts

Yes, many systems include warranties for performance. Confirm terms with your installer.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

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