"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

I highly recommend him. He' punctual, thorough, and the reports were much more detailed than I could've imagined. John sets the bar very high."

"What a surprisingly wonderful experience we had with BioClean. I was able to schedule a same day appointment, and Brian and Dennis showed up exactly on time. Both men are absolute professionals, and are extremely honest! Within minutes of entering the home, they measured the air for particulates, and said that it wasn't a high reading at all. They proceeded to test around our home, and also up in the attic where the air handler is. The thought to look in places we never would have thought to look, but they said everything was actually in good condition. We did figure out that there is moisture in the basement coming from what may be a leaky toilet on the main floor - which we never would have known. The took their time, were very thorough, and made no money from us (with the free estimate coupon they posted here on Angie's List). They could have told us anything, and we would have believed it (and probably paid through the nose). But - these guys truly are wonderful, honest, and professional. If we have more work to do after the plumber comes to fix the leak, we will DEFINITELY call them to do the work. On a scale of 1 to 10, they are a 43."
