"It went fantastic. Scheduling wise the gentlemen at Rhino Radon were quick to respond to our inquiry via there website were I filled out a online questionnaire. Once speaking to Henry about the specifics of my home via phone and letting him no my situation. They were prompt in scheduling a date for installation to assure my radon problem didn't delay my ability to sell the home. From the time I filled out there questionnaire on there website till the system was installed and fully operational, all took place In one weeks time. I no from experience that these days the attentiveness and service Rhino Radon provided me can be difficult to find. Having recently just finished the process of building my own home in Malden and dealing with a wide range of company's and workers. It's the little things that stand out like personal treatment,responding quick to inquiries or concerns and of course taking the time to do things properly the first time around while still treating the home with respect. Rhino Radon came recommended to me via a friend and I couldn't thank them enough for steering me in the right direction for my radon mitigation needs. I would like to do the same to anyone currently searching for a radon company. If you want the job done right and a pleasant experience, look no further for your radon needs then Rhino Radon Services.

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, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

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.
