"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!!!"

"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."

"Went good. It has been a HORRIBLE experience trying to buy a house in Northern NJ. This was our 3rd time trying to purchase one and our 3rd home inspection, but first time with Jeff. He was great. Thorough, knowledgeable, gave me insights and tips on things I never would have though of. We even had to deal with the owner being there during the inspection (FSBO). He handled it well. We ended up not buying the house after Jeff discovered some structural issues that ended up being way more than we could handle or the buyer was willing to address.

"When my husband and I discovered we had elevated radon levels we contacted a company that our neighbors used. They made us wait 2 weeks came out and gave us a price and then said they had to â think overâ how they would install the system. Frustrated- I did a search and found Garaâ s Radon. Kevin came out right away to give a quote. He was very professional and his price was lower than the previous company. He quickly and efficiently installed our system within a few hours. What was more impressive was the results of our radon test after the installation of the mitigation system, as they dropped from 10.0 to 1.20. Thank you Kevin!"

"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

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.
