"I had a pipe burst in the basement of our rental property, Flood Crew was referred by our realtor. They arrived quickly after the pipe was fixed by our plumber, demoed, and dried out the areas, even handled packing out our furniture and placing carefully in a pod storage while the work was being done. They did mold testing and made sure everything was safe, the best part was that they dealt with the insurance and we didn’t have to do anything."

Radon Detection and Reduction questions, answered by experts

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

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

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.

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).

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.
