National Radon Defense Companies in Illinois

MidAmerica Basement Systems
4525 Buckeye Street
Davenport, IA 52802
MidAmerica Basement Systems is your authorized National Radon Defense dealer for Iowa and Illinois.
Although no homeowner wants to increase cancer risks for family members, many people neglect to test their homes for radon, an invisible, odorless, cancer-causing gas that emanates from soil and rocks. Contacting a radon mitigation specialist to perform a radon test, or conducting your own test with a DIY radon test kit is the first step in protecting your family from hazardous levels of radon gas.

Radon mitigation solutions in Illinois

Most home issues are obvious, and as a homeowner, you're usually aware of the problem soon after it arises. After all, when your Illinois home has a structural issue or needs a new paint job or remodeling, the signs are clear and the benefits are obvious. But you won't see any signs when your home is harboring dangerous levels of radon gas.

That's what makes radon gas so hazardous - your home could have dangerously high radon levels, and you would never know without conducting a radon test. Radon is tasteless, colorless, and odorless, and because of these characteristics it's impossible to tell if your home is at risk. There could be a gas within your IL home that is proven to be the second leading cause of lung cancer in the U.S.

Authorized, highly trained radon contractors from National Radon Defense want to inspect your home to identify the radon levels and provide radon mitigation services to maintain a healthy radon level within your home.

We Provide:
  • Radon testing
  • Radon mitigation systems
  • Multi-family radon testing & mitigation
  • Vapor intrusion mitigation
  • Indoor air quality services
You Receive:
  • A healthy home environment
  • Clean indoor air
  • Protection for you and your family
  • Safe radon levels
  • Peace of mind

    The installation crew, Bill and Blue, were the best. They were very courteous and professional, explained everything and asked permission before starting anything. They were very hard workers, and made the installation much more quickly than I would have thought possible. They took great care to minimize the mess and dust, and were very neat and tidy at each step, cleaning up as they went. The installation looked great - very neat - and there was absolutely no mess left anywhere in my house. They even swept the driveway. I cannot recommend this crew too highly.

    The guys were very professional. The sales guy was very good explaining all aspects of the job. The two man crew was very good explaining things as they went along. I was at first surprised that only two guys were here, but I saw later that anybody else would have been in the way.

    Customer Testimonial

    Denise S.
    Monmouth, IL
    When Denise first purchased her home, she knew that she would want to someday finish her basement. After a few years of living in her home, she began to notice water seepages, putting her basement finishing project on hold. She knew that she couldn’t afford both basement waterproofing and basement finishing, so instead she left the basement unattended. When Denise heard of the WQAD Dry Basement Giveaway by MidAmerica Basement Systems, she thought she would give it a shot. Design specialist Joe Sarb, had inspected her situation and informed her on what she would need to do to fix her leaking basement. The day finally came when the winner was announced and Denise couldn’t believe it. She received a full perimeter drainage system, WaterGuard, and a TripleSafe sump pump. Denise also added CleanSpace Wall and a spray foam installation to help decrease humidity levels and increase the efficiency of the basement. She now has a dry basement that she can either leave the way it is, or finish it the way she would like.

    Zach and Lindsey tried to sell their house last year, and during their inspection an issue with their foundation was discovered and the sale fell through. They knew they would have to get the problem fixed if they ever had any hope of selling their house. Luckily, that was the same time MidAmerica Basement Systems was running a foundation repair giveaway contest. As the lucky winners, Zach and Lindsey got the repair work they needed. They were able to sell their home this Spring!

    Rene was great in her calls and email to me. She was always very attentive and careful to provide just the right amount of guidance and support. Cole Tatge was very very good. He spent much time with me, going over every detail and all of the rationale for the process and procedures. The presentation materials were excellent and the video was helpful. David Ezelle is an exceptional co-foreman. Together with Richard, the foreman, they made a cohesive pair. I was especially pleased that, in spite of some difficulty with the graph they were given, David and Richard went the extra mile to resolve the issue rather than merely going back to Davenport. David was especially professional in the way he approached the job and the way that he communicated with me. He was very careful regarding the preparation of the materials and equipment and the way that he completed the work. My driveway, sidewalk, and steps are now safe and neat. in spite of some difficulty with the graph they were given, David and Richard went the extra mile to resolve the issue rather than merely considering going back to Davenport. David and Richard were very careful to provide a thorough cleanup. They are especially meticulous, given the kinds of materials that they work with. I had tried to secure a local company for slablifting. I used Thumbtack. I only received a call back from one large company that is located in Missouri. Of my three inquiries, I made an assumption that they did not necessarily want to deal with senior citizens. That is my personal assumption. I subsequently used Home Advisor and found MidAmerica Basement Systems. I couldn't believe the exceptional professionalism and gracious care of each person with whom I was in contact

    Our design specialist was great. He actually took the time to listen, go through a list of about 40 questions I had concerning the installation of the proposed Radon mitigation system, provided a detailed sketch and a working plan after physical inspection and measuring of my residence. Two other supposed Radon mitigation companies I consulted with could not, would not, and did not do ANY of that! Bill (Job Foreman) and his crew worked together very well and were very considerate of their surroundings. They were Punctual, attentive, knowledgeable, professional, thorough.

    I chose MidAmerica Basement Systems because a friend of mine told me you did work at his home and he was satisfied with everything. Dillon and David were great. Nothing but good things to say about him and his crew. Kept me informed from start to finish. Worked with me when I wanted to make changes from the original agreement. I would have them back again to do work.

    So far, so good! The staff we've met have been great ambassadors for your company. Dan was friendly, professional, and communicated your company's desire to do exceptional work. Dillon and Doug faced extremely challenging conditions and unexpected obstacles with our basement. They were always positive and encouraging. They displayed an incredible work ethic! Dillon and Doug were as careful with our house and belongings as we imagine they would be with their own or a family member's. Competitive pricing. Responsive staff.

    Comment Other neighbors on our street have had radon problems and needed remediation. My husband and I have some of the symptoms listed with radon poisoning.
  • Project Location Tampico, IL 61283
    Comment I have Airthings testers. One in the basement and the other on the first floor. The reading in the basement goes as high as 5 or more. And the one on the first floor goes between .50-1.5. So I was just wondering if these levels are too high. I would like someone to come out and test. Thank you.
