"Radon Abatement services is a reliable dependable superb company. I have had an excellent experience from start to finish. Scheduling was easy and expeditious, service was professionally and very well done. Most importantly, Radon is gone with its in-house level reduced to almost its outside level. John Swett was very helpful and kindly answered all my emails and quickly addressed every concern I had. This project could not have been done better."

"CSI was flexible and was able to schedule a home inspector the day after I got a bid accepted on a house. The inspector, Patrick, showed up on time and the inspection took about 4 hours. Patrick was responsive to any questions I had by email or live during the inspection. My one recommendation is that I requested a pest, mold, radon, and home inspection. It would be a better heads up if they explained that they sometimes outsource the radon inspection depending on availability of radon inspectors. Also, they can explain a bit more for new home buyers what is involved with a mold inspection. Patrick ended up just eyeing whether he spotted any mold. Because he did not see any mold, we did not have to pay extra for mold samples."

Radon Detection and Reduction FAQs, answered by experts

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.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

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.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

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.
