"The installer (Davis) arrived on time, installed the system in about two hours, and showed me everything I needed to know about the system. The “before”and “after” test results were right in line with my own test measurements, which I took with a portable radon detector. The radon level dropped to a safe level after the system was installed, and that level has been maintained since it was installed in July of 2020, about 10 months ago. Overall, I was extremely pleased with A & R and I highly recommend them for radon mitigation work."

"Water Flo is fantastic. From Nick Sunday who did the walk through and estimate to the office staff and the installers, all are professional and friendly. No waiting months for the work to get done. The entire process took less than 2 weeks. Everyone was on time. The installation was neat and clean. The explanation of the equipment was presented so it was easy to understand and the radon system installed has dropped my levels 3 units!"

"Tom just completed a whole house Mold Remediation for me. Attic & basement. The attic which is split into two wings was heavily infested (?), the basement not so bad. This job was complicated by the fact that one wing had no easy access to the attic space. Tom resolved that nicely. He constantly went above & beyond and definitely put in more hours tha he had expected. But- would not take any extra compensation! I would definitely reccommends him for any future work."

"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

"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."

Radon Detection and Reduction questions, answered by experts

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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