"The work took two days. The price was almost 1/3 less than a competitor bid. They installed a French drain system and a sump pump. The other bid was for the glue on drain system which is actually not allowed in some areas and is not the better solution. There is a very good warranty on their work. The workers were very professional and skilled. I would highly recommend this company!"

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."

"AVOID AT ALL COSTS!!! Here is a list so you can read everything we’ve been through with this company. Spent over $11,000 in 2020 to have interior drain tile and a landing drain connected to a new sump pump Had water enter through the doorway by the drain 3 times since 2020, with the most water coming inside September of 2022 Called Safeguard in September 2022. Safeguard refused to even check the system, sent us a quote for $1,800 more work to “fix us up” without even checking anything on our property Had a 3rd party company out to inspect the drain that Safeguard refused to check. Discovered they breached our contract and connected the drain to village stormwater tiling without our consent or the consent of the village. Have never received as much as an apology. Instead, Safeguard blamed us saying the drain was clogged with leaves, and that is why we flooded. This was disproved by Roto-Rooter. Update as of 3/3/2023 AVOID AT ALL COSTS!!!

The company refused to fix anything and did not respond to requests until I submitted a formal complaint on the BBB website exposing the breach of contract Have spent months (5) trying to come to an agreement we are comfortable with in order to have them out to fix the work. They do say they will repair the work for free, BUT… They tried to get us to waive their liability should the village fine us for the stormwater connection. There will be NO WARRANTY of this free work. So, if the concrete starts breaking a few months after the fix, they’re not liable. They claim they did not connect the drain incorrectly, and they are doing this fix to appease us (even though I have my contact that clearly states what was to be done, and a signed letter from the president stating that they did in fact do something else). As a result, we asked for a simple 1 year work and materials warranty just to ease our fears about something breaking in the future. Their response- WE WILL NOT ALTER THIS CONTRACT. Bob, John and Karen have been nothing but awful to work with. They are argumentative at best. The amount of times sarcasm and ALL CAPS have been used in emails by Karen, as well as the amount of times my husband has been screamed at over the phone or in person by Bob and John are immeasurable. As soon as you write them a check and they finish the work, they’re done. Even if they blatantly breach your contract (like with us), or the work is faulty, I believe they will not fix or stand by anything. They claim they have one of the strongest warranties in the business- I assure you this is a lie. If they do work and it never breaks, consider yourself lucky, because if something goes wrong they will not help you in any way shape or form to solve the problem, in my opinion. Instead, they will blame you as the customer and ignore you until you become too loud to ignore. Do yourself a favor, spend a little bit more money and go somewhere else that actually backs up their work and treats their consumers well. This is not that place. RUN AWAY.

Basement Waterproofing questions, answered by experts

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

The best way to waterproof a basement is to install a properly functioning gutter system and a French drain around the outside of the foundation. The best solution for your home could involve other waterproofing methods that resolve the problem unique to your situation. Depending on your soil type, climate, and other factors, that could include sealing, landscape alteration, interior drainage systems, and more.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
