Just the ability to feel safer is one thing, but the quality of the components installed and excellent professional experience excels it to another level! It was an educational experience too learning a bit more about how radon works and how the fan installed works as well. Overall great experience would recommend 10/10! read less - 9/10/2021

I first spoke with Paul who talked me through all our options and explained what the mitigation system would be. He was extremely helpful and very patient. I also received quotes form other similar companies in the area and Radon Defense was very competitive. They were also the most responsive and seemed really passionate about their work. Our home inspector mentioned it might be difficult to install a mitigation system in the basement, so Paul came by a day before the installation to view the basement and go over everything. On the day of the installation Eric and his crew were phenomenal. They worked so quickly and efficiently! We were a little concerned about the noise of the fan, so Eric brought to types of fan into the house, plugged them in, and showed us the difference. Turns out, once they are installed and they pipes are on both ends, there is almost no noise at all! But it was so helpful to have him show us how they work. They talked through everything as they did it and the system itself looks like it had always been part of the house. Best of all, after they system was installed our radon levels have dropped from 12.7 to about 0.7-1. After the work was done, we purchased a Radon Eye kit, which we highly recommend, which constantly monitors the level of radon in the home. All in all, we could not have been happier and would wholeheartedly recommend Radon Defense to anyone who needs radon mitigation. Thanks Paul, Eric, and Linda! read less - 8/24/2021

The quote they gave me was accurate, and my radon levels dropped from above 5 to the lowest possible level that my home test could go (all results less than 1.1pCi/L read as '<1.1pCi/L').The installer explained everything they did quite thoroughly, from the gauge on the inside of the house, to the hole they drilled under the carpet on the opposite side of the house (that they later closed with cement and carpeted back over).They were also good about making sure they had an electrician come out the next day to hook up the external switch for the fan due to inclement weather, and they kept me updated and had everything scheduled and ready that weekend.I'd recommend this company to anyone that needs Radon Mitigation services. read less - 7/24/2021

In our previous home we had tested high for radon in our basement, which concerned us greatly. Someone in our neighborhood employed Radon Defense and raved concerning the prompt services provided by Nicholas. Though we had several quotes from different businesses, we selected Radon Defense to mitigate the high radon situation at hand. We were highly satisfied with the overall experience. read less - 5/24/2021

Installation took only half a day and they were very considerate of equipment location to keep everything out of view outside and out of the way inside. They performed a vacuum test to ensure the system would work. After the installation they explained each part of the system and how to maintain and monitor it over the years. Radon reduced from 7.5 pCI/L to 0.02 pCI/L within 48 hours and long term readings have been under 0.05 consistently with an airwaves radon meter. I highly recommend Radon Defense VA. read less - 5/24/2021

Radon Defense came highly recommended from our realtor. Nick and everyone who answered the phone there were professional, knowledgeable, and patient - we were nervous first-time homebuyers and had a lot of questions about radon and how to mitigate it. They installed a radon mitigation system quickly (despite it being peak season and a last minute request) and within a few days our levels went from 3.8 to under .5. I recently called them back with a follow-up question and they couldn’t have been nicer. I highly recommend this business for their quality work, immediate response, and customer care. read less - 2/24/2021

I have been using a radon detector for a around 6 months and after having a consistently high reading, I used Radon Defense’s website to request an appointment. Nicholas got back to me promptly and scheduled a radon test to be performed. Eric arrived on time at my home the next day and installed the tester. He is very friendly, professional, and had a knowledgeable response to all the questions that I had. After 2 days of testing they confirmed my reading was on average 6 pCi/L! I quickly scheduled to have a radon mitigation system installed. Eric and another gentleman were the installers and the quality of their work is amazing! The system is very quite and Eric explained to me how it works and how to read the meter inside the home for fan status. They also made sure to put down plastic/coverage on all flooring that they walked across and they put on disposable shoe covers as a second measure. I highly recommend this company. Everyone is friendly and knowledgeable, true pros. They have 5 star reviews for a reason. read less - 9/24/2020
