"Eric was great! Very thorough on his inspection, and even gave advice on things we didn't even think to ask about. He advised of the things that had the highest safety risk, right down to the small maintenance items like tightening screws. He recommended when to replace air filters, clean the fireplace and some optional things that could help us save money in the future. And the service didn't stop after the inspection, he continued follow-up about the radon testing, and the how to address the safety issues that needed to be fixed. He was very professional and friendly. I would definitely recommend him to friends and family."

"They were on time when promised. The work was done fairly quickly (about 3-4 hrs) and they left no mess. Most importantly, the work done has solved the radon problem, lowering numbers from 15-25 down to less than 1."

Radon Detection and Reduction questions, answered by experts

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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.

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.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.
