"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 employed the services of Radon Mitigation Master to run a radon test, install a radon mitigation system, and then retest. From start to finish, John and Ed were punctual, always communicated and kept the line of communication open for any questions I had. They conducted the install very quietly, clean, and efficiently. They then retested, and the system was able to reduce the radon by 90% plus. I would recommend RMM to any acquaintance, friend, or family member. Thank you John and Ed!"

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.

Radon Detection and Reduction FAQs, answered by experts

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. 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 preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
