"Radon Shield was hired after I got a higher then expected reading for radon in by home when selling it. Benedict shared a lot of great advice about radon gas in the home, he was able to schedule the install in a very fast time frame which was extremely helpful because I was selling my home. The quality of work was outstanding and he did a great job explaining thing to me and by wife. He also did a great job cleaning up after the install. I would hire Radon Shield in the future in needed."

"A two-man team worked very efficiently to remove each vent cover and vacuum inside the vent openings throughout the townhouse. One man removed the vent covers while the other man vacuumed inside the vent openings. No problems with how they worked but I think there are other companies who perform a more thorough cleaning of ductwork using other methods. This company did a superficial cleaning and worked very quickly. In and out within an hour.

Radon Detection and Reduction questions, answered by experts

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

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

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.

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

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.
