"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!!!"

"Top notch company and extremely professional. They did an excellent job and worked with me on the best placement for the radon mitigation system. Perhaps the best review I could give them is to say I will be hiring them to do my own house as well as I am situated on the Reading Radon belt. The job I am rating them on was my Dadâ s house which I am selling."

"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 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.

Radon Detection and Reduction questions, answered by experts

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.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

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 cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.
