"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
