How to Choose an Illinois Basement Waterproofing Company

Wet basements are not fun! Flooded basements are a homeowner’s nightmare. If you are suffering from constant worry about the health and safety of your basement, it’s time for a change. If you’ve tried DIY efforts to fix pooling water, cracks in your foundation, leaky basement windows, or high humidity, it’s time to find an experienced, professional waterproofer you can trust. A wet basement wastes valuable living space, damages building materials and stored possessions, pollutes the indoor air, risks the health of those living in the home, and puts your investment in your home at risk. That adds up to considerable risk.

1. Look for expertise, training, and experience.

When you choose a basement contractor in the Basement Systems network, you get a local company trained in and committed to the best waterproofing practices. Each contractor listed here is an expert in the diagnosis of sub-grade moisture problems as well as the design and installation of proper drainage, moisture and humidity control, and basement materials. Say good-bye to your wet basement with the best basement waterproofing in your neighborhood!

2. Demand high-quality basement waterproofing products.

These top Illinois contractors have exclusive access to Basement Systems’ award-winning waterproofing products. Basement Systems’ products have set the standard for dry basements since 1987. With access to 27 patented Basement Systems products, your local Basement Systems dealer can tailor the right solution to address your specific basement or crawl space problem. With solutions like the WaterGuard basement drainage system and the UltraSump industrial-strength sump pump, your basement can be ready for the next big rainstorm.

Other basement waterproofing products include high-performance self-draining basement dehumidifiers that also serve as air filters, basement wall and floor treatments, window wells, and basement window replacements. Browse the full line of basement waterproofing products.

Why do Illinois Basements Get Wet?

Some customers want to understand why they’re plagued with a leaky basement or humid, musty air in their basement. It helps to realize that Illinois has wonderful water resources, from the Mississippi River in the west, the Ohio and Wabash Rivers in the south, and the beautiful Lake Michigan shoreline. If you live near these bodies of water, the cycle of winter thaw and river runoff, along with the spring rainy season, may lead to water in your basement multiple times a year. In recent years, Lake Michigan water levels have been at their highest, putting homes in the greater Chicago area especially at risk.

But it doesn't take a once-in-a-decade flood or even a flash flood to ruin your basement. A sudden heavy thunderstorm can dump a lot of rain in a short time and if your basement windows are rusty or the ground is already saturated with water, then your basement is likely to get wet. There are also a number of reasons unrelated to precipitation that cause leaky basements, from plumbing failures to the grading of the land around your foundation. Whatever the reason for a wet basement or foundation, it always makes sense to diagnose the problem and find a solution that prevents further damage.

Basement Waterproofing & Crawl Space Repair Solutions

If you're dealing with a flooded or leaky basement right now, you don’t need to understand why your basement is wet. You just need a permanent fix. The waterproofing experts in the Basement Systems network have helped homeowners across the state of Illinois for decades, by identifying the source of leaks, flooding, groundwater seepage, and musty odors. With a range of waterproofing and moisture control solutions available through Basement Systems, your local dealer will install the right solution for your basement or crawl space.

Customer Testimonial

Denise S.

Monmouth, IL

When Denise first purchased her home, she knew that she would want to someday finish her basement. After a few years of living in her home, she began to notice water seepages, putting her basement finishing project on hold. She knew that she couldn’t afford both basement waterproofing and basement finishing, so instead she left the basement unattended. When Denise heard of the WQAD Dry Basement Giveaway by MidAmerica Basement Systems, she thought she would give it a shot. Design specialist Joe Sarb, had inspected her situation and informed her on what she would need to do to fix her leaking basement. The day finally came when the winner was announced and Denise couldn’t believe it. She received a full perimeter drainage system, WaterGuard, and a TripleSafe sump pump. Denise also added CleanSpace Wall and a spray foam installation to help decrease humidity levels and increase the efficiency of the basement. She now has a dry basement that she can either leave the way it is, or finish it the way she would like.

Zach and Lindsey tried to sell their house last year, and during their inspection an issue with their foundation was discovered and the sale fell through. They knew they would have to get the problem fixed if they ever had any hope of selling their house. Luckily, that was the same time MidAmerica Basement Systems was running a foundation repair giveaway contest. As the lucky winners, Zach and Lindsey got the repair work they needed. They were able to sell their home this Spring!

West Peoria, IL

Rene was great in her calls and email to me. She was always very attentive and careful to provide just the right amount of guidance and support. Cole Tatge was very very good. He spent much time with me, going over every detail and all of the rationale for the process and procedures. The presentation materials were excellent and the video was helpful. David Ezelle is an exceptional co-foreman. Together with Richard, the foreman, they made a cohesive pair. I was especially pleased that, in spite of some difficulty with the graph they were given, David and Richard went the extra mile to resolve the issue rather than merely going back to Davenport. David was especially professional in the way he approached the job and the way that he communicated with me. He was very careful regarding the preparation of the materials and equipment and the way that he completed the work. My driveway, sidewalk, and steps are now safe and neat. in spite of some difficulty with the graph they were given, David and Richard went the extra mile to resolve the issue rather than merely considering going back to Davenport. David and Richard were very careful to provide a thorough cleanup. They are especially meticulous, given the kinds of materials that they work with. I had tried to secure a local company for slablifting. I used Thumbtack. I only received a call back from one large company that is located in Missouri. Of my three inquiries, I made an assumption that they did not necessarily want to deal with senior citizens. That is my personal assumption. I subsequently used Home Advisor and found MidAmerica Basement Systems. I couldn't believe the exceptional professionalism and gracious care of each person with whom I was in contact

I now own my parent's home at 210 Bluffview Ln Collinsville Il 62234, which is where the work was completed. The Team was great to work with. I live in Tennessee and Woods was really good about working with me long distance. I discussed my needs with the Office Staff and setup an appointment for an estimate. The Sales person who came out was on time and great at answering my questions and helping us come up with a solution. The Crew called before they arrived and the Lead Crewman introduced himself and others and we went over what was to be completed. He kept us informed; he also made suggestions when we ran into an issue with the drain pipe and Woods repaired that also. The Lead Crewman haul off the old drain pipe and offered to haul off the old timber for us also, which was appreciated. I can't say enough about the guys you all sent out, the Crew was great, friendly, and completed the work in a timely manner. The Woods Inspector came by the work site to introduce himself and observed for a while. All in all we had a great experience with the whole team. But best of all...with the heavy rains Collinsville had not too long ago, THERE WERE NO LEAKS IN THE BASEMENT AREA! I would recommend you all. Keep up the good work..you don't see that type of commitment from companies and the team that works for them much any more.
