"The company's responsiveness to our urgent situation was extraordinary. The owner made a 60 mile trip to examine our situation on Sunday morning! He expected at least a week before they could do the work, but he got it done the next morning so that we would have safe water...we had been waiting for another contractor for more than 3 months! The installed radon mitigation system has performed flawlessly. We are grateful and confidently give AquaMax our highest recommendation."

"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

Radon Detection and Reduction questions, answered by experts

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.
