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 13,000 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.

    Happy Customer
    Happy Customer, Naperville
  • 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.
