Great service, great experience from testing to mitigation. Professional work. Nicely done. The Radon level got down from around 6 to below 0.4. Highly recommended. My house had different levels of concrete slabs and foundations and very hard to access crawl space. They could install the system for those different parts greatly. Thank you. - 3/31/2024

I don't normally write reviews unless something goes wrong but this place impressed me. Called on a wed, they were here on Friday (couldn't do Thursday due to rain, can't work on outside pieces of system in the rain.) Tech showed up on time and repaired unit in about an hour, even inspected tubing and found some seals were bad and resealed them for me. Totally professional and polite. I normally dread repair service visits because usually someone is up selling me. These folks did exactly what was needed, at the reasonable price they quoted over the phone. Highly recommended. - 3/09/2024

Paul You and your team do a great job. My wife and I will continue to refer your company and now that I know you will tell them about my experience with you when I had a question years after the installation. Great service when Nicholas and Eric installed and same great service years afterwards when we had questions. - 2/08/2024

Radon Defense is awesome. Eric came out to our property and went over the entire process with me, taking time to answer each of my questions.on top of that, he was very friendly. Every time I called the office, everyone I spoke with was very friendly and helpful. Eric and the crew (Kevin and Chris) were kind enough to assist in my moving things around and they completed a masterful project in less than a full day. Kevin was kind enough to make certain that everything was placed where I wanted and advised as to the best locations for the fan output. Eric also took time out of his day the following day to fix a small (non-mitigation-related) hiccup. Best of all, the price was fair and our numbers dropped almost immediately (we monitor with an AirThings). Everyone on this project has been absolute pleasure to deal with and I feel much better know my family is breathing clean air in our house thanks to Radon Defense. - 11/15/2023
