"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."

"Benedict showed up 40 minutes earlier than the scheduled time. He installed a two-pipe system in my basement in under 5 hours. My radon levels went from 4.0-7.0 to 0.7! He got all the permit application paperwork done and all I had to do was drop it off and schedule the inspection. I highly recommend Radon Shield, LLC."

"Radon Shield was hired after I got a higher then expected reading for radon in by home when selling it. Benedict shared a lot of great advice about radon gas in the home, he was able to schedule the install in a very fast time frame which was extremely helpful because I was selling my home. The quality of work was outstanding and he did a great job explaining thing to me and by wife. He also did a great job cleaning up after the install. I would hire Radon Shield in the future in needed."

"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."

"Michael arrived a few minutes early which was great. He was extremely thorough and knowledgeable regarding the home inspection. He took the time to show and explain several potential issues. Michael went above and beyond to make my wife and I feel at ease with the home purchase. He provided a detailed report with the whole house write up and pictures within hours of the inspection. We highly recommend Michael to anyone looking to get a home inspection or any other home services in NJ. You won't be disappointed."

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.

FAQs for radon gas abatement projects in Princeton, NJ

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
