"The consultation appointment was setup quickly, the salesperson was genuinely nice and took time to answer all my questions. The company itself is well organized, everyone was on the same page for the whole process. The installation for our radon mitigation system went smoothly. The crew was pleasant and did a great job."

"Radon Systems LLC did a great job. I had a radon level of around 6.5 in my basement for years, and finally decided I needed to address it. After receiving 3 quotes, I had Dave from Radon Systems come over to do the job. I initially was resigned to having the PVC pipe go up the side of my house, but Dave found a way to run the piping inside the basement and go thru the garage, with only 18" of PVC sticking up past the garage roof. Excellent! And now my radon level is around 1.0 to 1.5 all the time. The entire job took half a day, and Dave was clean, respectful and easy to work with. I absolutely recommend them."

"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!"

"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.

Radon Detection and Reduction questions, answered by experts

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.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

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