MidAmerica Basement Systems is your premier locally owned and operated company that specializes in foundation repair, basement waterproofing, crawl space repair, concrete leveling, and radon mitigation.

"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

Through air sampling devices and surface swabs in key areas of concern.

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.

Using an air purifier in your home or basement isn't an effective way to reduce or mitigate radon. Radon is an inert gas, meaning it doesn't react with other chemicals and can't be filtered the way particulates can be. While an air purifier can help improve your indoor air quality in other ways, don't rely on it to reduce radon.

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.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.
