"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

"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!"
