"OUTSTANDING WORK on short notice. The Radon Shield team did some very impressive work for us and we will certainly reach-out to them for other services in the future. For this project, we asked Mr. Ugorji and his team to install 2 separate radon mitigation systems for a large sq ft home with a basement air radon concentration well over 4 pCi/L where masonry drilling would be required for the installation. We also faced difficult time constraints, but Mr. Ugorji arranged to begin work the next day. Before visiting the work site, we discussed the installation, the home, expectations. He provided a clear and accurate assessment of the costs and time/effort required for our project (our final bill matched his initial assessment, nothing added, no surprises). The location for the installations, routing of piping and wiring, model fans to be used, attachment and sealing methods, follow-up testing, and much more were discussed before work began. Our preferences were addressed and pros/cons were weighed. Mr. Ugorji worked efficiently and his team tidied-up as the work progressed. All aspects of the installation were handled professionally. Care was taken to upgrade remote junction boxes and other components impacted by the new system. The routing of the suction/exhaust piping was thoughtfully designed, securely installed, and tightly sealed. When both systems were turned-on, they presented matching suction levels, indicating effective under-slab suction. The end result is a very effective radon mitigation system that has (after a few days of constant electronic monitoring) achieved a basement air concentration of 0.35 pCi/L. Mr. Ugorji followed-up with us a few days later to check on the new radon test levels and to ensure everything was as expected."

"The service was a Radon Remediation System...not listed above. Benedict and his brother were GREAT. I needed it to sell my home and they drive 90 miles and come out in just a couple days. The work involves boring through your basement floor, piping up and out of the house and up above the roof line with a fan and pressure gauge installed. I was apprehensive but trusted their "get right to it" attitude and the finished project is neat, clean and sealed in all necessary areas. Long term exposure to Radon can potentially cause cancer. The home tested as high as 5.2 (4.0 is bad) and after the system was installed another test read 0.3...virtually none. They were easy to deal with by phone, text and email and while I am unhappy that I had to spend the money, I feel it was WELL SPENT. I highly recommend them to resolve such a "mysterious " issue."

"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."

"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.

Radon Detection and Reduction questions, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.
