"Rob was excellent at his craft. He installed a radon fan and covered 2 sump pumps. His price was very reasonable and he was flexible with his schedule. The quality of work exceeded my expectations. Was very communicative which was helpful."

"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."

"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."

"Looking to finish my basement, so I did a radon test. It came in at 2.5, which isn’t bad but I wanted to get it lower. Fresh Air LLC came out and set me up with a mitigation system. Upon re-test, the level was under 0.4. They were quick and effective."

"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.

"I recently used Quality Home Inspection Services as I'm in the process of purchasing a condo. Jamal took the time to explain everything he inspected as he preformed a thorough and detailed inspection of the entire unit, any questions I had were answered immediately with great detail and clear understanding. He provided the written and detailed report very quickly(same day), with pictures, explanations, summary, and any levels of concern or priorities. I would definitely choose Quality Home Inspection Services again in the near future and recommend their services for anyone who’s in need of a thorough and detailed home inspection."

Radon Detection and Reduction questions, answered by experts

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.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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