"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."

"Bill and his wife Deanna were extremely professional and thorough. I wanted to be present for the inspection and they welcomed me with open arms. Answered all of my questions, and went above and beyond to ensure that I left the inspection comfortable. Bill can perform radon testing and is certified for mold."

"He was on time, arrived at 9am as quoted and began to install the system. The system required two suction points and a sump pit cover. The sump pit originally had a pedestal pump in place and none of the other radon companies would change the pedestal pump to a submersible pump as required for the mitigation system to function properly. Rhino Radon not only changed the pump but installed a back flow check valve to ensure proper functioning of the system. All of the other companies said we would have to employ a plumber or a handy man to get this done. Had we gone that route the closing would not have happened. Rhino Radon gladly did all the work required and didn't even break for lunch!!! He was more concerned with getting us out of the vacant house seeing we are already down the cape. The system that involved a crawl space and being vented through the garage roof was completed immaculately and the test results came back at 0.5 pCil/L. This pleased the lender and buyer and exceeded our expectations. We highly recommend Rhino Radon Services.

"I couldn’t be more impressed with this company. From start to finish, the level of professionalism, communication, and thoroughness was truly exceptional. John arrived on time, fully prepared, and immediately demonstrated an expert-level understanding of every system in the home. His attention to detail was remarkable—he didn’t rush, he didn’t cut corners, and he explained every finding in a clear, approachable way that made the entire process feel stress-free. One of the biggest standouts was the range of services offered. Having sewer camera inspections, chimney camera inspections, and a mold assessment available in one appointment saved me so much time and money. John used modern equipment, including a drone for the roof inspection, and provided high-resolution photos, videos, and an incredibly organized report. What really makes John special is the pride John takes in his work. It’s obvious he genuinely cares about protecting his clients and helping them make informed decisions."

Radon Detection and Reduction questions, answered by experts

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

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.

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