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.

    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.

    "Thank you for your patience. You all were kind and easy to work with. The job was very well done." With more than 45 years of experience, Thrasher has a reputation for providing high-quality, long-lasting basement waterproofing solutions. We have access to more than 30 patented basement repair products designed to keep your basement clean, dry, and odor-free. Some may think that water intrusion issues are only experienced in residential properties. However, these are, in fact, problems that don't discriminate on what type of construction they burden and can have a detrimental effect on any structure. This brings us to The Burlingame Federated Church. This beautiful traditional brick church structure is nestled in Burlingame, KS. This structure was built in 1908, at which time it was the home of the Methodist Church. In 1948, the Burlingame Federated Church was formed by uniting the Baptist, Methodist and Presbyterians. Rev. Sam McCain Jr., the pastor of the Federated Church, said in a 1951 Kansas City Star article, "The idea of one church is scripturally sound. Without a united church, we can hardly hope to proclaim the gospel in a powerful way to a divided world". When you're talking about a structure that is this rich in history, inevitably, Thrasher knew we had to help out when The Burlingame Federate Church contacted us in 2015 in deep distress. The Church had been dealing with a hefty amount of water intrusion and were at a loss of what to do. Thrasher was able to arrange a time for one of our award-winning system design specialists to go out and meet with the members of The Burlingame Federate Church. As no two construction jobs require the same work scope, this is a necessary step to ensure that we can provide our customers with a top-notch experience. After a thorough inspection, the Thrasher System Design Specialist and the Church members could determine the best solution. A total of 265' of our non-clogging Water Guard interior drainage system and two of our Triple Safe Sump Pump Systems was the most fitting solution. This will ensure protection from the three most common causes of pump failure and guaranteed to keep their church basement dry year-round. In addition to the selected products used for The Burlingame Federate Church, Thrasher has multiple other solutions to customize every waterproofing need. Including the SaniDry™ Basement Dehumidifier and Air Filtration System can eliminate the leading cause of basement odors – high humidity and other indoor air allergens. Our approach controls the relative humidity of your basement to prevent mold from growing. Also, if you plan to finish your basement, we can restrict moisture and water vapors from entering the structure by adding a layer of basement sealer to protect from the mold at the same time with our CleanSpace® Basement Wall Vapor Barrier. Our highly trained specialists can install a complete basement waterproofing system with speed and accuracy. Besides, we never use subcontractors, and our crews are trained to minimize any mess and disruption. We will work hard to keep your home, business or Church clean, protect the floors and the walls, hang plastic to isolate the work area, and add ventilation fans to remove most of the dust so that you can have peace of mind while we complete your project – and protect your property for years to come. At Thrasher, we prioritize our customers' satisfaction above all else and want to make sure you are delighted with our basement repair services. That's why we offer a 25-year transferable warranty as well as a satisfaction guarantee, and efficiency guarantee, and a property protection guarantee. We understand that you may want to have another contractor bid on your project. Our goal is to have the best work done at a price that works for you, which is why we offer a price assurance guarantee when you choose to work with us. If another Better Business Bureau registered contractor provides you the same scope of work at a lesser price within 30 days, we'll match their proposal. If we can't match or beat another company's proposal for the same quality of work, we'll return any deposits you may have paid. Thrasher prides itself on being the right solution for any customer. We offer free basement repair inspections and custom repair solutions to solve your leaky basement problems permanently. To learn more about our price assurance guarantee and book your free no-obligation estimate, please call or book online. Thrasher believes we are only as strong as our customer's impression of us. This is why we depend on the feedback from the previous customer we've worked with. Below is the review from Burlingame Federal Church.
