"They found that I was above the normal level for radon after a 48 hour test, and gave me the number for someone that would take good care of me. The guy was super nice. My wife felt very comfortable in the house with Tony Domingues as our inspector. He walked me through what the results meant and told me the other services they offer. I will definitely take advantage of their expertise with other inspections I will need.

"Tom was in a word: Phenomenal. I scheduled an Inspection and Radon Test on HomeAdvisor. Tom reached out within minutes of my scheduling the appointment. He was extremely thorough yet timely and gave simple suggestions. The last thing he sought to do was to nickel and dime us- we truly appreciated that. He was very personable and kind. His prices we the best in the area (we shopped around) and the quality of his work speaks for itself. We've favorited him and will be giving him a ring for our next home."

"They came back and checked on it when the levels weren't quite what they should be. I only have good things to say about them. They were very professional and knowledgeable. They seemed to have a lot of information about radon and how to have it removed from our house, and keep the levels down. The price was reasonable."

Radon Detection and Reduction FAQs, answered by experts

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.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

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

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 cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.
