Radon Detection & Reduction

"Installed radon mitigation system in basement. Pros: 1) reduced overall radon levels by about 75% 2) they did the work in extreme cold temps 3) done in about 4 hours Cons: 1) They arrived late (although they did call to let me know) 2) they did not wear boot covers or put down any floor protector when walking on my carpet 3) they set dirty toolboxes and caulk guns directly on carpet 4) exhaust pipe is too close to roof peak and can be seen from street view of house Overall, good job. I can live with seeing the pipe from the street. I would recommend based on the overall work."

"Serviceman was nice but when I called the office to complain the man was maniacal, SCREAMING at me. He certainly needs to learn how to treat customers along with some anger management sessions."

"Salesman that we were to replace dry wall. Later learned we were to have it removed. Attempts to reach supervisors and owners resulted in zero until time to do installation. Gave $1300+ down. Note: this went to the salesman, not to MABS. Then salesman stated $12,000 more if MABS removed the dry wall. Paid salesman and his friend to remove it but didn't do all of it! Sent certified letters to Cedar Rapids address after we got no verbal responses to phone calls. Later learned they receive no mail there, only in Davenport. Were to have GFI outlet placed at far end of basement. 3 electricians said not possible. Also discharge was to be underground to rear of yard which we thought meant to back! House sits on clay. Was to discharge under ground out 10 feet from house. Canceled installation and have found that other basement waterproofing companies do not require 2.5 feet of dry wall removed: only baseboard. Cost was same as MABS. Now we must pay to have drywall installed after the waterproofing is completed."

Radon Detection and Reduction questions, answered by experts

Avoid opening windows and keep doors closed during testing to obtain accurate readings.

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.

No level of radon is technically safe, but because it’s everywhere—even in the air outside—it’s impossible to avoid entirely. Instead, the Environmental Protection Agency encourages taking preventative measures if the levels of radon in your home rise above 2 pCi/L. (For reference, the average radon level in homes across the United States is 1.3 pCi/L.
