"Radon Systems LLC did a great job. I had a radon level of around 6.5 in my basement for years, and finally decided I needed to address it. After receiving 3 quotes, I had Dave from Radon Systems come over to do the job. I initially was resigned to having the PVC pipe go up the side of my house, but Dave found a way to run the piping inside the basement and go thru the garage, with only 18" of PVC sticking up past the garage roof. Excellent! And now my radon level is around 1.0 to 1.5 all the time. The entire job took half a day, and Dave was clean, respectful and easy to work with. I absolutely recommend them."

"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

"Steve was well knowledgeable and picked up on what most home buyers would not. As a Realtor for over 14 years, I have to say Steve was a perfect fit for the job. He took the time to make sure the buyer knew exactly what was going on and explained what each problem was about. My clients really loved him. Thanks Steve!!!"

"Amazing service and support. They have had communication through the phone, and reach out when performing their tasks! I would totally recommend and love to have them back, my old floors by the new stove and fridge, looks like I refurbished into a whole new home! They just go over the top and the extra mile, I love that from companies I hire and you’ll hear from me again."
