"Radon Systems LLC did a great job. I had a radon level of around 6.5 in my basement for years, and finally decided I needed to address it. After receiving 3 quotes, I had Dave from Radon Systems come over to do the job. I initially was resigned to having the PVC pipe go up the side of my house, but Dave found a way to run the piping inside the basement and go thru the garage, with only 18" of PVC sticking up past the garage roof. Excellent! And now my radon level is around 1.0 to 1.5 all the time. The entire job took half a day, and Dave was clean, respectful and easy to work with. I absolutely recommend them."

"The two techs were very professional and courteous. They installed a high performance radon fan and 3" pvc pipe with two different points of extraction in my basement. They had to work partially in a crawl space which made the install more difficult. They cleaned up all debris and left the work areas immaculate."

"On first call Storch takes your basic info including the radon level and you then get a call from Fred Storch who is presumably the owner operator. He asks further qualifying questions about whether the basement is finished, where windows are located, etc. They then set a time for the visit within a 30 minute window. The crew arrived as expected and discussed where to do the install - we surveyed various options and selected a location that had minimum impact on interior and exterior aesthetics. Job was done quickly and professionally. Very happy with the outcome."

"Hank did an excellent job. This was my first home (condo) inspection so I didn't know what to expect. What I like the most about Homepro is the binder you get after the inspection. Inside there is a report of his findings along with great descriptions. The price was very fair. $350 for the inspection, $25 for pest FHA form and $125 for radon testing. I would recommend Homepro to anyone looking for an inspection. I would definitely use again."

FAQs for radon gas abatement projects in Manville, RI

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.
