"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."

"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."

"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."

"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!"

"My review is a little mixed. he spent his time explaining a lot, gave great recommendations and estimates on what it would cost to renovate and such. very personable, and in his defense, he asked me if i had any questions. not afraid to get dirty and get onto the roof which was risky with the loose floorboard. also as a member of BP, i have high expectations. 
things i did not like: 
access to the roof was sealed, and that was it. no drone to take a look up top, no ladder to get up there. so i am paying more to get a roofer to inspect and estimate. he did attempt going through the loos floor boards, which was brave. 
there was a lot of mouse poop but we didn't investigate further, just stated that there was no indication of termites. not sure what the difference would be if i opted out of the termite inspection.
the girl on the phone assumed i was lying when i said there was no basement based off zillow or google stating there was a basement, and so i'm pretty sure they priced me as if the home had a basement. 
he checked the power outlets in the vacant unit, but not the other outlets in the unit with the tenant, assuming everything works?
things i did like:
he took his time explaining everything and giving the life expectancy of the appliances. even gave repair estimates
knowledgeable about the area and old buildings
found that there may be something on the ground unit as it was hollow, doubt others would have spotted that. 
advised on the tank sweep, cutting the tree that was growing over the driveway, electrical box which should be re-done. 
overall, the report was adequate, wished we did something about the roof, but his contract states if there is an obstruction or sealed, he won't go in there which sucks for me. swell guy, i'll try others to see how he better compares.

Radon Detection and Reduction questions, answered by experts

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.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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