"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!!!"

"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!

"It is a bit premature to say completely satisfied, because I won't know until radon testing is done how successful the exhaust fan and sealing of sump pump has had on my radon level. Will say that Pete, owner and operator of Fresh Air Solutions was very cooperative to work with and seems to have a good knowledge base of radon remediation. Appreciated that he was very respectful of my wishes and concerns.."

"Peter came to my house to do a full home inspection and a radon test of my three family home. He actually arrived a few minutes before I did. I gave him some background on the property and outlined for me what areas are included in the inspection and then he got to work. The inspection took around three hours. Peter took a lot of photos which was great. I have a flat roof and this is a pretty high building and I refuse to go up there. So his photos really came in handy for me. And I also have an attic area that I could not walk into, so having the pictures are very helpful in this instance as well.
He is also very knowledgeable and informed on every area that he covered and he does not mind being interrupted with questions. He gave me a lot of great suggestions and really helped me to understand clearly and simply what areas I should pay close attention to and address. He takes his time and always wants to know if you have questions about anything. I highly recommend Peter.
Thanks again Peter for your review of my property. The report is well written, detailed and will be very helpful in addressing items that need my immediate attention.

"Dave spent an hour and a half on the outside alone. He left no stone unturned unless the seller had furniture or boxes in the way. He had been in the construction business for 30 years, and that was very apparent. He found things I would have never thought of, and was honest when he found good things as well. He spent the time to explain and remind me of even the simplest safety things you should do in a home, like hitting the test and reset buttons on outlets once a month. Apparently they break after a while and don't work at all. I would definitely recommend Dave!!
