"John was great, came to inspect our home in Rochester and was professional and had every piece of equipment you could need to give us a detailed look into our house. Even when the seller made a mistake on the sewer and water system types John helped us test both and went above and beyond. Cannot recommend enough if you want a the best and safest bet for an inspection!"

"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.
