"I hired Erickson Foundation for radon mitigation. Job went smoothly. They communicated well, were very professional, and reviewed all potential options for the job with me. The system installation was done on time, professionally done, and well cleaned-up. The equipment is high quality, with the 10-year warranty being a big plus."

"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."

"George and his team were extremely friendly and professional. This is a good group of people. Courteous and thoughtful, they were able to do a complete installation of both systems from scratch in about 6 hours.
The new radon remediation system (Bubble Up) has the added benefit of boosting the fixture pressure in the house to city level or better (60-75psi) as well as completely resolving the pH level of the water.
The cost was slightly lower than the other two quotes we received, partially due to the fact that Absolute offered a "multi-system" discount since two systems were going in at the same time.
If in your service area, I would highly recommend George Doumit of Absolute Water System.

"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

"Spoke to James on the phone and he was extremely helpful! I thought I disturbed asbestos when I picked some layers of wallpaper off a wall and was very nervous. James talked me through it and helped me realize I didn’t find asbestos. He was extremely knowledgeable and I wish I could have met him in person!"

Radon Detection and Reduction questions, answered by experts

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 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.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.
