"Rob was a good match for us and the work that we needed done. Communication was strong - response was swift, including for at least one accidental phone call. His installation work was 5 / 5. Because he was working in a rail space that had been recently insulated; the project manager also inspected Rob's work to make sure his team did not need to do any follow up repairs. He was very impressed by Rob's workmanship. Rob's mitigation work resulted in a significant reduction in radon levels as measured by our Corentium Home 2 devices from Airthings, this device measures radon/temp/humidity continuously and allows us to monitor levels via the app. if you are concern about radon in your home, I would recommend both Rob from Tri-state, and understanding your long term radon levels using a device such as the Corentium Home 2 device. Below is a snapshot showing the reduction in radon levels in our crawlspace after Rob completed his work."

"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."

"It is my absolute pleasure to write this raving review for Benedict Ugorji (the owner) at Radon Shield LLC and I make no commission recommending him. The radon level was 1.8 pCi/L when I bought my home in Holmdel, NJ, in February 2021. I wanted to lower the radon level for personal health reasons (I have a young 3 year old) not for a real estate transaction (goal level <4 pCi/L). Safe levels were established in the 1970s (The history, development and the present status of the radon measurement programme in the United States of America. Radiat Prot Dosimetry 2015; 167(1-3): 8-14) so maybe new safe levels should be lower than the current recommendation to reflect available technologies for radon mitigation as there is no safe level. I spent $700+ for a new Fantech Rn4EC-4 fan and to seal the French drain serviced through RAdata in Flanders, NJ, and the level was unchanged at 1.6 and 1.9 pCi/L after servicing. RAdata is a disorganized business that will recommend the most expensive system (the energy recovery ventilator) that costs $3000 that other radon companies (I got two second opinions) will say that it does not work. Then RAdata proposed to install a second mitigation system right next to the current system, but could not intelligently justify why the second system would be right adjacent to the current system where there is already subterranean air flow generated by the current system instead of tackling the no subterranean air flow zone at the farthest end of the basement. Please refer to my review about RAdata on Yelp and Facebook and my subsequent reply to their response for details. I kept looking for another radon company and fortunately I found a gem in the unscrupulous radon business. The gem is Benedict whom I unwaveringly and unequivocally recommend. Benedict is responsive – he patiently listened about my radon situation and collected information about my pre and post service radon level and even information down to the granular level like what make and model fan RAdata installed. Benedict came to my home for the consultation, to run the diagnostic tests, he proposed solutions and offered his rational, he did the installation of the second mitigation system (in the area of the basement with no subterranean air flow) from start to finish by himself, he used a more powerful and cheaper fan for the second system (than the one RAdata installed for my first system), and he guaranteed to lower the radon to a specified level in his contract. Benedict charges one flat service fee (whereas RAdata charges the first hour and then at 15 min increments so you are discouraged from asking questions). Benedict took his time to explain to me about how a fan’s performance (like moving air measured in cubic feet per minute or CFM) is affected by your soil’s static pressure (the value on your u-tube manometer). He even followed up with me on a Saturday via text message about the short term radon level measured with the Corentium radon detector (while the charcoal kits are being sampled) and guided me through interpreting the short versus long term average as the values were quite different. We touched based again when the charcoal test came back and the levels were an astonishing 0.5 and 0.6 pCi/L!!!"

"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."

"While I’ve never had a home inspection before, I believe they all should go as smoothly as the home inspection with Luciano. Communication and setting up the appointement were a breeze. Luciano is informative and thorough but not an alarmist. I would highly recommend Luciano to any friends looking for a home inspector."

Radon Detection and Reduction questions, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

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.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

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.
