"Chris came to my house. He was here for about four or five hours. He really worked hard getting around all the other pipes and things in the basement. He’s very thorough and what he does. Every aspect of the job was done precisely. I would hire him again and recommend him to anybody that needs a Radon system. And he’s a very nice guy. I hope this helps you on picking a good Radon person to do your radon system. Northern New Jersey Radon services is the one to choose."

"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."

"My home was recently tested for radon, and needed remediation. I'm glad I gave Radon Shield a call! Benedict was able to come by within the week to take a look. He walked me through the challenges, and we were able to figure out where to put the system in a manner that followed regulations and was still fairly unobtrusive. He had given me an estimate over the phone, so there were no surprises when the time came. They installed the system on the spot. My large and cluttered basement wasn't the easiest to work with, but Benedict and his team were able to handle it professionally and cleanly in the span of about 5 hours. With the system they installed, they brought the radon level down from 5.6 to 0.8. I wish I had tested for radon again a few years ago and installed this system sooner. I think they even left the basement cleaner than when they started! Thanks again!"

"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.

"I am a first-time home buyer who was looking to buy in Newark, NJ. I was Hesitant about the foundation walls, heating and electrical systems in the home. Because they are well-regarded as trustworthy a friend of mine, who had previously had issues with her home, suggested I call Quality Home Inspections. When I spoke with the gentleman on the phone (very polite), All my questions were answered in detail and my concerns were alleviated. Quality Home Inspections also provided me with lead and radon inspections. The best part of all was receiving the inspection results in a time efficient manner. They were very professional. I am currently moving forward with purchasing the house and recommending Quality Home Inspections to anyone looking for a great lead/radon home inspection Service."

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.

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.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

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.
