"Jon was very quick to respond to my messages and was able to fit me in to his busy schedule to come take a peek and evaluate the issues. Turns out there is no immediate problem and that no remediation was necessary. He recommended some good solutions for humidity for me to research further. Jon was very friendly and you could tell that he's a straight shooter. I would definitely look to hire him should I need his services in the future."

"At the time of this review, there may be more steps to follow. My pre-mitigation test readings were 16.7. I found Dennis through HA, and he promptly got in touch by phone and explained what he would do to mitigate the radon and what it would cost to do so. His aim is to get the reading down to 2 or lower. He indicated that, depending on what the nature of construction of the building and the subsurface conditions, he might be able to do it in one step for a stated price, but it in some cases a second step might be needed, for an additional price (less than half the â one step priceâ ). He and his son came when scheduled, worked efficiently and neatly, but indicated when done that a second step might be needed depending on the results of a new radon test. Since we are not in the process of selling the property, Dennis suggested that I not commit to pay for a. Second step that might not be required based on new test results. I have now received the test results, which indicate that the step one process reduced the radon levels below the EPA recommended max, but not as low as Dennis would like to achieve. So I am in the process of â discussingâ with him whether and when to have him back to perform the second step. I appreciated Dennisâ s manner of dealing from the very start. He was very conscious of not causing me to incur extra costs."

Customers say: Quick response

"This is our first time buying a home and everything I read online made me feel I wasn't likely to find an inspector who actually took the time needed to really look at everything and give us a good inspection. I looked at 4 websites of inspection companies and chose Omega. The website provided information about Stuart and what his inspection covers. Our first call with him was pleasant and he was upfront about all the answers to our questions and the pricing. There were no surprises. He arrived early for the inspection, really took his time to examine, poke and test everything. He walked us through what he was looking at and explained any problems or lack of problems. He was very thorough and we'd recommend him to anyone! We'd also use him again if we have the need. You won't be disappointed with his service in any way!"

"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

Radon Detection and Reduction questions, answered by experts

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
