"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."

"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."

"Radon Shield did a wonderful job with radon remediation in our basement - our level was below 4.0 but we wanted it even lower. Benedict and his team worked efficiently and carefully, and our radon level is now 0.3 upon repeat testing after fan installation. They are professional and reliable - highly recommend their services."

"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 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

Mitigation reduces radon levels, protecting your health and complying with safety standards.

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

Installation typically takes 1-2 days, depending on the system and property layout.

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).

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.
