"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."

"Where to start? Jeff came early and was already checking out the outside of the house by the time we got there at the scheduled time. He was available on a Saturday and he made it work with ours and his schedule which was nice.
Once we got into the house he encouraged my wife and I to follow him around and listen to his sound and super experienced information and advice about every little facet of the house. He took a lot of photos and notes which we should be receiving a report from soon.
He notified us of things that might need more immediate repair and things that could be done over the course of the next few years. Jeff was a very nice, knowledgeable and friendly guy who just wants to get the job done right and is definitely on your side (the buyer).
I would highly recommend Jeff to anyone I know looking for a home inspection. Not only did his price include the home inspection but he also checked for termites and is in the process of doing the radon inspection in the basement.
Highly recommended and he'll even refer you to a good company for oil tank sweeping (who also doesn't charge an arm and a leg) if you need that as well.
Thanks Jeff!

"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."

"Peter is quite good & thorough enough in his inspection. He is very punctual, and responsive in his (email) communications. Gives a thorough report, even though I thought he focuses more on a few points on the outside of the house, and not quite 'inside-out'. I had to follow up & clarify quite a few things inside with him.
But overall he seemed to be very experienced, and thorough in his analysis.
Gives a big report, exactly within 48 hours, as promised. Quite a few things in the report seemed repetitive, but overall had all details & plenty of pictures from every possible angles. He also sent the Radon report after a few days, as promised.
There are quite a few things that he won't check, some of them might be obvious (as kitchen appliances), but it would have been good to know in advance what all things he does, or doesn't. He would have you sign the waiver / contract terms only after the inspection is done. I would suggest to ask those from him beforehand, and decide on yourself.
I would rate him 4 out 5 in terms of quality of inspection.
But for all other aspects, professionalism, politeness, punctuality, responsiveness etc, indeed a 5 out of 5!
Cheers.
