"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."

"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

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

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.

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

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.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. 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 action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.
