"Radon Shield replaced a broken fan on my radon remediation system. The replacement was in place and working within 4 hours of my initial call. Benedict discussed the pros and cons of increasing the fan power. He clearly explained the potential benefit, pulling up the relevant literature from each manufacturer so that I understood the difference. Having just finished my basement, I eventually decided to upgrade the power (with a small increase in cost) but did not feel any pressure to do so. I was very satisfied with my overall interaction, and wouldn't hesitate to call Radon Shield again."

"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."

"Jeff did a great job!  He was very thorough and took the time to walk us through each and every aspect of the house.  This is our first home purchase so we had no idea what to expect, but Jeff provided us with a great education.  He pointed out potential issues but also pointed out things that were in good shape, which was very reassuring for us.  All in all, I would recommend Jeff for anyone looking for a quality home inspection in New Jersey.

"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!!

FAQs for radon gas abatement projects in Mahwah, NJ

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
