"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."

"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."

"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 is quite good & thorough enough in his inspection. He is very punctual, and responsive in his (email) communications. Gives a thorough report, even though I thought he focuses more on a few points on the outside of the house, and not quite 'inside-out'. I had to follow up & clarify quite a few things inside with him.
But overall he seemed to be very experienced, and thorough in his analysis.
Gives a big report, exactly within 48 hours, as promised. Quite a few things in the report seemed repetitive, but overall had all details & plenty of pictures from every possible angles. He also sent the Radon report after a few days, as promised.
There are quite a few things that he won't check, some of them might be obvious (as kitchen appliances), but it would have been good to know in advance what all things he does, or doesn't. He would have you sign the waiver / contract terms only after the inspection is done. I would suggest to ask those from him beforehand, and decide on yourself.
I would rate him 4 out 5 in terms of quality of inspection.
But for all other aspects, professionalism, politeness, punctuality, responsiveness etc, indeed a 5 out of 5!
Cheers.

"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

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

Yes, many systems include warranties for performance. Confirm terms with your installer.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.
