"This year, my shop was in the basement (I make turned wooden bowls) radon level inexplicably increased from the 2.5 - 4.0 level to 8.0 - 11.0 level. I decided I was not going to work down there unless I did something about radon abatement. The guys said I needed one port under my basement floor, but I opted for two --- one near the exit port of the system and one in the center of the house. I had crushed stone and a vapor barrier under the floor, but radon was still getting in. After the installation lasting 3 hours, twenty-seven hours after install, the level was 0.83. Now after 1 week the level is 0.48 I am ok with that. I have not seen the results from the lab yet, but my continuous meter has been a good indication of what is happening. I am concerned now about radon in my drinking water, but cannot comment on that yet. Dick P Alna, ME"

"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
