"National Radon Defense Midwest employees were very knowledgeable and helpful. As we were selling our house we discovered that we had high radon readings and needed to mitigate the problem. They explained to us the process and clearly identified what they would recommend to resolve the issue. We thought it was very reasonably priced and feel confident intheir products, staff and installation"

"This job was completed efficiently and professionally. A design specialist came to test and measure every detail for the project. The crew arrived with everything needed for the job. They worked very hard to install Waterguard in the concrete floors inside around the foundation to the sump pump basket. They also installed Geo-lock anchors to support a block wall that was bowed. This company has 36 years in business and provides excellent results and professional customer relations. Call Amer. Wtrwrks for a free estimate. You will not be disappointed. A wise investment of $11,270."

"Our radon specialist, Tim Milledge, was terrific. Communication was excellent, he arrived on time, was professional, courteous and experienced. He was able to run the pipe line and place the other equipment in a way to be unobtrusive and did nothing to detract from the aesthetics of our property. He explained post procedures and cleaned up after himself, unusual these days with service providers, and completed the installation quickly and efficiently. We would highly recommend SWAT and, in particular Tim."

"They did a good job. They came out pretty much when they say they would and they did get it done. I found them from Angie's List and they have a lot of good reviews but the thing that I didn't like was he said that it would only take like a day or two and it sounds like he didn't communicate well. The first time I called they didn't call me back and I tried to contacted them through the e-mail from Angie's List and the owner that comes checked that out really quick. So he came, he check and saw that I e-mailed and I talked to one of his workers between that. He got right back to me as soon as he got involved. He got the estimate and we talked about the job. They came out here and they ended up working week and what it sounds like was however he delegated the job, he didn't delegate enough people for the job that needed to get done. It rained when they are in the middle of working and they covered my porch roof but it leaked a little bit. It didn't turn out that anything was really injured, they really felt sorry about that and offered to do anything that I needed to to make it right. I got my job done and got it done well but there were definitely some glitches. They cleaned up nicely. The employees were nice and the employee that was on site felt terrible, he felt that it was taking so long for it to go through, he felt that he must calculated and I guess what happened was he had ordered the roofing for the porch and it was suppose to be delivered but our delivery time was off. He felt like it can get it done before the rain comes but then because it wasn't delivered on time he was not able to do that and got into trouble. Then the owner came out to find out what was going on, he's going 'Oh my God, we really didn't put enough people on this job which the guy actually out here didn't say all along', but generally they were professional group and they know what they were doing."

Radon Detection and Reduction questions, answered by experts

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.
