"Well, Joel did eventually manage to get a good result, reducing the radon level to 0.6. And the work he did was neat and tidy. But it took him 3 tries and cost me 3.5 times the original estimate. Original estimate $1525, actual final cost $5272. And he left me stuck with a $1300 â high efficiency fan that I did not need. What the heck am I supposed to do with it? And why did not he just do what he finally ended up doing, moving they system to a different location, instead of perseverating at the original location using an industrial strength fan? In retrospect, I am not sure about his judgment. Plus he has real issues with timeliness the work took 12-15 months to complete, including 4 (count em 4) reschedules each of which ended up with my job being knocked to the back of the queue despite the fact that it was Joel who canceled each time. Finally, it took him as long as 12 months to get me a paid receipt for the first two attempts (totaling in excess of $3200) which were paid in full at the time he did the work. I am still waiting for a receipt for the final almost $2000 of work."

"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 level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

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.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

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

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).
