History of Radon Reduction Systems, Inc.

Dave and Vickie Masa of Naperville, IL founded Radon Reduction Systems, Inc., in 1991. Since then the company has successfully mitigated over 15,000 homes. In the late 1980s Dave worked as a State Licensed Plumber and Vickie worked as a Realtor. Dave started to see the need for Radon Mitigation in new construction and existing homes. At the same time Vickie started to hear about radon at the office and how many buyers were refusing to close on homes unless a radon reduction system was installed. Soon they both left their jobs and started RRS, Inc. together.

Rebecca Masa Wise

Dave and Vickie Masa welcome their oldest daughter, Rebecca Masa Wise, to Radon Reduction Systems, Inc as Health Outreach Coordinator. Growing up in Naperville, Rebecca remembers the palpable passion her parents had for their small business and the hard work and dedication it has taken to grow their company to become one of the most reputable Radon Mitigators in the state of Illinois. In High School, Rebecca would join her dad on jobs as the “Radon Girl”, which gave her a deep respect for the craftsmanship of each and every job The Radon Man completed. Over time, she pursued her degree in Spanish from Illinois State University, then went on to earn a Master’s Degree in Social Work from University of Illinois at Chicago. Rebecca seeks to expand the community’s perception of Radon beyond the real estate transaction, framing it as a personal and family wellness issue. Just as we would not want lead in our drinking water or asbestos in our floors, we should be proactive about removing Radon from our homes to avoid exposure to the cancerous radioactive elements contained in Radon gas. Rebecca strategizes to provide outreach and education via social media and connecting with health-focused individuals and organizations in Naperville and surrounding communities.

  • Dave installed an active radon mitigation system for us 11 years ago when we bought our house. The fan motor failed within the 5-year warranty period and he happily replaced it for free with no questions. That replacement motor lasted 8 years and we just had him out to replace it. I would have expected his fee to increase over the last 11 years but it didn't. Since this motor runs 24/7, I was surprised that we got those 8 years out of it. He spent plenty of time with me discussing another radon mitigation issue which he then fixed at no extra charge. He encouraged us to get another radon test and promised that if there was any problem he'd fix it for free. It is very rare to run across anyone who stands behind his work as well as Dave does. I recommend without hesitation.

  • It was completed flawlessly. From the moment I spoke to Dave through the quote process and the implementation, it was totally professional. The area around the system is neat, caulked and perfectly clean.
