"It went great. I highly recommend them. They were a pleasure to deal with. The person that came out for the estimate answered all of my questions. The estimate was fair. The work was done on schedule and with no problem. At completion, everything was explained to me. I used their electrician which worked out fine. After completion the radon test showed that my level was now undetectable."

"We hired PureTech to advise us on a real estate inspection that included a radon test. That test came back over the safety threshold. After meeting with Zach C, he advised us to make some repairs in the basement and to schedule a retest. We did and the results speak for themselves; the levels came back well into the safe zone. I couldn't be more pleased with the recommendations made by PureTech and Zach C specifically. Saved us a bundle in what could have been a nightmare, and now the sale of our home can proceed. Thank you PureTech!"

Radon Detection and Reduction questions, answered by experts

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.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.
