"They installed a Radon Mitigation system in a house I was selling. They had the best price, the experience I wanted, and were able to install a few days after I called. Technician was very nice and efficient in getting it installed. Good warranty too. I had my system installed in an encapsulated crawl space."

Customers say: True professional

"Jeremy was very professional and did a great job. He had reached out after I scheduled the original appointment to reschedule due to poor weather conditions. He offered to move the appointment to a date/time that he usually doesn t work to accomodate my needs. Once he had finished his work, he walked my fiance and I through everything explained it all very clearly. He also thoroughly explained the process for testing radon levels and getting test results back after the mitigation installation was complete. Would definitely recommend his services as he did a great job and his quote was very competitive."

Radon Detection and Reduction questions, answered by experts

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.

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

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.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

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.
