"Dennis did a very efficient installation for us at a reasonable price. After the setup, we noticed a few issues, including noise, exterior configuration, and radon levels. I reached out to him several times but initially did not receive a response, which caused me some stress. Eventually, Dennis responded and explained that he was in the hospital for a major procedure, yet he reassured us that he would address our concerns once he was discharged. This shows that Dennis is a reliable and considerate professional. I will update my review once our issues are resolved, but so far, I believe his service deserves a 5-star rating. It is impressive that even while in the hospital, he still thought about his clients an admirable work ethic!"

"Mohan was just phenomenal. We called him on a Friday to see if he could do a home inspection for a house we plan to buy. I had difficulty scheduling a time when he and my buyers agent were both free, so Mohan called my agent himself to work out the schedule. Within 5 minutes of calling Mohan, I had an inspection scheduled for the next day. The appointment was for 1pm and he said it would take about 1.5 hours. We arrived a few minutes before 1pm and Mohan had already arrived and inspected the roof — he came early because it was going to rain and he wanted to still safely inspect the roof. During COVID19, Mohan was very clear ahead of time how we were all going to maintain safety. He wore a mask the entire time and had a laser pointer to show us stuff from a safe distance. He took pictures of everything. He explained everything and was so patient with us, especially as first time home buyers. Mohan also isn’t alarmist but still very upfront about potential repairs. For example, Mohan would say that we should replace the hot water heater because of leaking and explained how much it would cost. He also would show us stuff that didn’t need to be fixed now but should be fixed within the next X amount of years. He even showed us preventive stuff - for example, the gutter downspouts were draining right next to the home, which has a stone foundation and can be highly susceptible to water damage. Mohan suggested to buy a dehumidifier and place it in the basement to prevent moisture and prevent damage that hadnt even occurred. The appointment was for 1pm Saturday and by end of the day, I had received a written report of his inspection."

"Be careful. I called to have a radon mitigation system installed and the sales rep on the phone took down the information and scheduled the appointment. I was upfront about an interior drain being installed. When the technician arrived, he said he'd be happy to install the system, but that it would be worthless because of the interior drainage system. I then received a $200 invoice for the site visit. Frustrating scenario to have a sales rep schedule the appointment, knowing full-well that I had an interior drain, and then the technician tell me there's no point to install a mitigation system, but then charge me for the inconvenience of it all."

"Rob was a pleasure to work with. We had to have a more unusually sized radon mitigation fan replaced. Rob handled sizing and installation and even informed us about the manufacturer warranty for the model. Would definitely use him again. "

"It is really a nice experience to work with John and Kevin. Our house has a funny foundation. There is a block in the middle and half of the house has radon and the other half does not have much. At first time, Kevin came on time, worked very professionally and got the first pipe and big fan installed. But unfortunately, this pipe is in the not much radon side and the radon score did not drop down too much. We were very worried and called the EAGLE ENVIRONMENTAL again. They arranged the second appointment and Kevin did more tests and installed the second pipe on the side of the foundation WITH NO EXTRA COSTS. And then magic happened, our radon number dropped to almost 0 now. :) Thanks you Kevin and EAGLE ENVIRONMENTAL again for the fantastic work!"

FAQs for radon gas abatement projects in Dedham, MA

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.
