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

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.

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.

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.

Investing in a crawl space project is a big commitment. After Mid America Basements Systems did the work there was no doubt it was worth it.

We were a little disappointed that it took a day longer than expected. This was mainly because they had difficulty finding a place to take the dirt they dug out. We would have thought that would have all been lined up before the crew was sent out. The cover is marred but the installer was very happy to request a new one for us which is what we asked for. Thanks! The window looks great. Now bring on a good rain to make sure it solved our problem! :)
