"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"

"I have worked with many contractors,plumbers,electricians, etc. in my time owning two homes. On here in New England and the other in Pembroke Pines,FL. These gentlemen from rhino radon services were deffinelty personable and proffesional I felt like my home was in good hands with this company. After calling around and having a job scheduled with another mitigation company I was blown off and left with a short deadline. Luckily after speaking with Henri from rhino radon they were able to squeeze me right in your schedule the very next day even though they had two other jobs scheduled they showed up at 5pm and still completed the job to ensure I met my closing date, if your looking for a standout and accommodating radon company I would say look no farther then rhino radon. I was very pleased with the service I recieved. HIGHLY RECOMMENDED

"Bill and his team are wonderful. They do a thorough inspection to uncover issues. They've saved us from buying a house that would not be the right fit for us. They also let us know what we need to do to keep the house we live in now in good condition. They are not the cheapest option, but of course you pay more for quality, experience, and knowledge. They also offer different options so you can customize your inspection. We have used the thermal camera option, the radon option, and sewer options for the inspection so that we can learn as much as we can about the condition of the house. Very happy with Bill and his team and would definitely use them again."
