"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!"

Radon Detection and Reduction FAQs, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Installation typically takes 1-2 days, depending on the system and property layout.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.
