"John was great, came to inspect our home in Rochester and was professional and had every piece of equipment you could need to give us a detailed look into our house. Even when the seller made a mistake on the sewer and water system types John helped us test both and went above and beyond.

"They were the first to give us a quote and were able to come out as soon as we needed them to. Installation was smooth, and they have been good at following up to make sure the system is working. Because our radon is still slightly high, they are doing another radon test and will follow up if it comes back high yet again. We would definitely recommend them to others!"

"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

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.

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.

Yes, many systems include warranties for performance. Confirm terms with your installer.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

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