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 

Radon Defense is an excellent business. They educated us about radon when we bought our new home, and provided radon testing at a reasonable and fair price. They answered all of our questions and are extremely knowledgeable and professional. - 6/24/2021

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

Nicholas and his team were very friendly and informative, taking the time to explain how their system would be installed and work per the configuration of our home. They explained all the piping options, and we decided to spend just slightly more, well worth it, to have the outside exhaust pipe match our gutter system in both shape and color to blend in better. In just a few short hours Nicholas found the best place in the basement to drill in and install the system. It is totally quiet and unobtrusive. This was a few months ago, and today my radon reader reads a mere 0.35 reading for the past 30 days, and a 0.51 Long Term Average. Great work and a great product by Radon Defense! They were a real pleasure to work with and I know they are there for me for long term support. We now have peace of mind knowing there are no longer any health risks. I highly recommend Radon Defense for any household's radon mitigation! read less - 9/24/2020
