"Chris came to my house. He was here for about four or five hours. He really worked hard getting around all the other pipes and things in the basement. He’s very thorough and what he does. Every aspect of the job was done precisely. I would hire him again and recommend him to anybody that needs a Radon system. And he’s a very nice guy. I hope this helps you on picking a good Radon person to do your radon system. Northern New Jersey Radon services is the one to choose."

"Radon Shield was hired after I got a higher then expected reading for radon in by home when selling it. Benedict shared a lot of great advice about radon gas in the home, he was able to schedule the install in a very fast time frame which was extremely helpful because I was selling my home. The quality of work was outstanding and he did a great job explaining thing to me and by wife. He also did a great job cleaning up after the install. I would hire Radon Shield in the future in needed."

"The service was a Radon Remediation System...not listed above. Benedict and his brother were GREAT. I needed it to sell my home and they drive 90 miles and come out in just a couple days. The work involves boring through your basement floor, piping up and out of the house and up above the roof line with a fan and pressure gauge installed. I was apprehensive but trusted their "get right to it" attitude and the finished project is neat, clean and sealed in all necessary areas. Long term exposure to Radon can potentially cause cancer. The home tested as high as 5.2 (4.0 is bad) and after the system was installed another test read 0.3...virtually none. They were easy to deal with by phone, text and email and while I am unhappy that I had to spend the money, I feel it was WELL SPENT. I highly recommend them to resolve such a "mysterious " issue."

"Fantastic to work with. I received an elevated radon level after a recent test which required mediation. RAdata were very responsive and timely. They even called several days prior to my appointment to offer a new time after a cancellation. They arrived on time, quickly diagnosed the problem, and performed the required work. The technician took the time to fully explain the system and offer suggestions after a new issue was found. I would highly recommend their services."

"Looking to finish my basement, so I did a radon test. It came in at 2.5, which isn’t bad but I wanted to get it lower. Fresh Air LLC came out and set me up with a mitigation system. Upon re-test, the level was under 0.4. They were quick and effective."

"It was a terribly cold and rainy day (it had just snowed 6inches).  Despite these conditions, he said he preferred to do the inspections and it proved very fruitful.  He arrived at the house 30min before the inspection time and had already taken countless pics and assessed the exterior prior to our arrival.  We walked around the house, checked out the roof and exteriors, gutters, etc...Spending nearly 90min just on the exterior!
We then moved inside to the basement, and once again, he walked us through every single step and provided great simple explanations to any questions we had.  In total, we spent approximately 4 hrs to finish the inspection on the 3400 sq ft house.
Going back to the rain, he was dead on!  We found a minor leak in one part of the roof which our Seller arranged to fix. This would never have been found on a nice, sunny day!
As promised, 2 days after the inspections, we received a very thorough report and 2 days after that (4d after inspection), the radon report. 
Everything went exactly as anticipated and planned.

Radon Detection and Reduction questions, answered by experts

Mitigation reduces radon levels, protecting your health and complying with safety standards.

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

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.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.
