"Work is scheduled for June so I can speak to the initial meeting with them. Wayne was very friendly and took time to explain what I need done and why. He was very thorough and suggested things I had not been advised to do by a prior company that was not listed on Angi. He sent me a complete quote the same day that I accepted"

"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.

"Main Choice Inspections is the best inspection company out there. They are so thorough and their reports are very detailed. They really are a one-stop-shop and do everything including: sewer line scoping, well flow test, septic inspection, mold testing, water testing, air radon testing, and the list goes on. I wouldn't hire anyone else to inspect my home! Always quick to respond and answer any questions for myself and my clients. When you use MCI to inspect your home.... you have them for life! FIVE STARS!"
