"Danny Wine from A2Z Inspection provided excellent customer service. He was professional, and always quick to reply. I asked a lot of questions and he was patient and thorough regarding the process. I was in a rush to book my home inspection and he was accommodating. You never know these days when finding service online but A2Z proved to be trustworthy and professional. I would highly recommend using them. Five stars for sure!"

"Frontier Foundation and Crawl Space Repair is a top notch company! Their work is timely and second-to-none. Mark inspected and serviced our crawl space dehumidifier along with our radon mitigation system. He is a true professional who went above-and-beyond, and I will definitely request him on future inspections. I feel confident in the quality work Frontier provides and strongly recommend them to anyone in need of crawl space/basement/foundation work! Thanks again, Mark!"

Radon Detection and Reduction FAQs, answered by experts

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.

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.

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.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.
