"I called John on a Thursday night looking for a 9AM, next day inspection of a property on auction that I needed inspected before I put my bid in. He answered my call, texted me, planned everything and was there at 9am ready to work. He gave us his immediate thoughts so that we could make an offer with good info and then sent us a super detailed report. I couldn't recommend him more. He gave us great peace of mind."

"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.

"Called me back within 30 mins of my inquiry. After a cordial meeting over the phone and a full understanding of what my concerns were, and stating clearly what it would cost me, he arrived less than 24 hours later. He was a very nice gentleman and he got right to work. He was complete in his imspection related to my concerns and not only explained the problem but also had the right tools to present a slide show of my house and the areas that needed addressing. He's his own man, not there to promote any contractor and I have since called him again to address other areas of concern related to the foundation of my 100+ year old house."

Radon Detection and Reduction questions, answered by experts

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

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

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.

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).
