"Jeff did a thorough evaluation including moisture testing to determine if we had any issues and if he could be of service to us. We were provided an extensive amount of education on the subject and the best plan of action moving forward. I'd highly recommend NU-Life as your go to mold resource."

"Our home has a radon mitigation system. We asked Janet to take Radon measurements, review the existing system, and make recommendations. She took measurements for 48 hours and determined that our radon levels were actually very low and that no further remedial efforts were needed. The price was very fair and no attempt was made to sell us something that we don't need."

"Tom was very responsive and answered my questions before the inspection. He arrived punctually for the inspection and was very thorough. He contacted me after the inspection to give me his overall assessment. Tom provided a comprehensive report, including many excellent pictures, within two days, as promised. His fee was very fair. I highly recommend TC Inspections."

"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 questions, answered by experts

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

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