"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."

"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."

"Where to start? Jeff came early and was already checking out the outside of the house by the time we got there at the scheduled time. He was available on a Saturday and he made it work with ours and his schedule which was nice.
Once we got into the house he encouraged my wife and I to follow him around and listen to his sound and super experienced information and advice about every little facet of the house. He took a lot of photos and notes which we should be receiving a report from soon.
He notified us of things that might need more immediate repair and things that could be done over the course of the next few years. Jeff was a very nice, knowledgeable and friendly guy who just wants to get the job done right and is definitely on your side (the buyer).
I would highly recommend Jeff to anyone I know looking for a home inspection. Not only did his price include the home inspection but he also checked for termites and is in the process of doing the radon inspection in the basement.
Highly recommended and he'll even refer you to a good company for oil tank sweeping (who also doesn't charge an arm and a leg) if you need that as well.
Thanks Jeff!

"While I’ve never had a home inspection before, I believe they all should go as smoothly as the home inspection with Luciano. Communication and setting up the appointement were a breeze. Luciano is informative and thorough but not an alarmist. I would highly recommend Luciano to any friends looking for a home inspector."

"Dave spent an hour and a half on the outside alone.  He left no stone unturned unless the seller had furniture or boxes in the way.  He had been in the construction business for 30 years, and that was very apparent.  He found things I would have never thought of, and was honest when he found good things as well.  He spent the time to explain and remind me of even the simplest safety things you should do in a home, like hitting the test and reset buttons on outlets once a month.  Apparently they break after a while and don't work at all.  I would definitely recommend Dave!!

Radon Detection and Reduction questions, answered by experts

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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).

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.
