"I recently purchased a foreclosure which tested with elevated levels of Radon during the home inspection. There were some companies that offered significantly less expensive solutions, but not impressed as their bids provided no information and would have been out the basement and up the side of the home which does not look very nice. Midwest Radom came out and we found a route out the basement, through the garage up through unfinished attic space, and out the roof which allowed the exit pipe to come out the roof on the backside of the home. This was actually decided upon during the initial install when we discovered the original solution presented by the estimator was not workable. They were not going to put firestop collars because I live in MO and "that is not required by code" even though I had discussed it with the owner when I first called, because I had done my homework and learned they are important and asked for them. They were going to charge more, but ended up honoring their original offer which I appreciate and feel is reasonable for some 4" PVC pipe, 2 X 2 plastic sheet, 4" radon fan, vacuum gauge, 2 fire collars, and 1 roof penetration flashing with 3-4 hours of labor with 2 technicians. They had to do a penetration from the basement to the garage and from the garage to the attic space. They pulled from an existing outlet for power for the fan and a final penetration out the roof. It took 2 trips to complete the work because it was raining or snowing the first trip they made. They charged $1005.00 for the job and took less than 4 hours to complete. They also performed a follow-up test which showed a decrease in Radon levels in the safe range. I highly recommend Midwest Radon because their price was fair for a good job done to my expectations based on industry best practices which are higher than what the state of Missouri presently requires."

"I would definitely recommend this company to anyone!!! I hired them and the job was done nicely, Dan O'Brien was the technician who took care of the project and he did an excellent job, he answered all of my questions and explained to me everything related to Radon gas. When he finished setting everything up and the job was completed all the working area looked super clean and the installation looks just like it is part of the house and that has been there forever. This is what I call a Perfect and Complete execution of a Radon gas mitigation project."

Radon Detection and Reduction questions, answered by experts

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

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.

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.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.
