"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.
