"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."

"The project went very well - Benedict explained what he would need to do clearly before we started, was prompt on the day we scheduled the fan installation, and worked efficiently. Our radon level is now 0.3 in our basement following fan installation. Highly recommend Radon Shield!"

"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."

"David inspected a potential home I was looking to purchase and he was so thorough that by the time we were done it gave me a very clear understanding of what issues the house had, what needed fixing and what was downright dangerous. When buying a home, you need a great inspector like David because if you don't get a good inspection you run the risk of buying a big money pit. I bought a home once before but that was a joke compared to the great inspection David did. The home David inspected was a small 1200 sq. home but it was built in 1935 and so he did mention we should expect to see some things pop up. However, he went above and beyond and I am so grateful for his hard work that I will recommend him to others in the future as well and will call on him again for inspections. He also brought Alex, a septic inspector, with him who was also very thorough and very good and provided a very through report. Thank you, David, for your wonderful help! You have no idea how much I appreciate it."

"I chose this company based on Angies list reviews and it did not steer me wrong. His schedule was accomodating and we were able to book a time within just a few days from my call. On the day of the inspection Peter called me and let me know he might be a few minutes late (which I appreciated) but he showed up a few minutes ahead of schedule. He was very thorough and made sure that we understood whatever he was showing us before moving on. He was meticulous and spent most of his time on the exterior and basment as that is where the majority of major issues would be. In this case their happened to be a huge drainage problem. He was very knowledgeable but was careful to state his boundries when dealing with structure problems. He suggested that we pull the permits for any work that was done and to contact a structural engineer. We didnt even get that far because we pulled out the day after his report was sent. The report was completed within 48 hours and was 48 pages long. Obvisouly not all of it was extermely important details, but necessary nonetheless. Peter was also careful not to provide us with opinions, but rather focus on providing us all of the relevant information so that we could make our own informed decision. I'll be calling him again soon when we find another home to purchase.

FAQs for radon gas abatement projects in Freehold, 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.
