Why Do Iowa Basements & Crawl Spaces Get Wet?

Flooded basement: Iowa, the heartland is flat and fertile for crops but the flat area makes it easy for heavy rainfall to cause local flooding issues. When flooding hits your area, your basement is most likely to be the prime target for water damage.

Other wet basement signs: There are many possible sources for pooling water, damp basement walls or flooring, and high humidity. These include: rusty basement windows, poor grading around the foundation, leaks through cracks in the foundation, saturated soils, simple plumbing failures, and poorly functioning drainage or sump pump systems. A basement already musty and damp is ill-prepared for the next bad rainstorm! Basement waterproofing can address the underlying issues, prevent future water damage and improve the indoor air quality.

  • WQAD Dry Basement Giveaway Allows Homeowner to Move Forward in Waterproofing Basement in Monmouth, IL Read Full Testimonial

    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.

    "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.
