"Jeff and his folks were a pleasure to work with. His communication regarding any delays or other issues is excellent. He is also great at answering followup questions that I have about how the system is running. It took our radon readings down to nearly zero from an alarmingly high value. We were hovering below 4 pCi for many years, but then our crawlspace was sealed and insulated and it soared in the living space. (The crawlspace itself was 20 pCi). Highly recommend."

Radon Detection and Reduction questions, answered by experts

Installation typically takes 1-2 days, depending on the system and property layout.

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

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.
