Mankato, MN Dependable Basement Waterproofing & Crawl Space Repair

This Mankato, MN homeowner was about to do a major basement remodel. They wanted to take their dark, damp basement and turn it into a beautiful, usable living area. Wanting to bring the space up to code and make it more inviting, they decided it was time to install an egress window.

After an on-site evaluation, we recommended a RockWell egress window system for its durability, clean look, and built-in safety features. RockWell window wells are made from high-strength composite material that won’t rust, rot, or collapse under pressure, which is ideal for Minnesota’s freeze/thaw cycles and wet soil conditions. The built-in steps also make it easy to exit the basement in the event of an emergency.

We carefully excavated the area outside the basement wall, cut a new window opening, and installed a code-compliant egress window. We then set the RockWell window well in place, secured it, and ensured proper drainage to prevent future water intrusion. Once the installation was complete, the homeowner was thrilled with how much light the basement gained, as well as the peace of mind that comes with having a safe exit.

This upgrade not only improved the home's safety and comfort but also increased its value by bringing the basement space up to modern standards. If you're in the Mankato area and considering an egress window installation, we offer free in-home estimates and expert solutions designed for your unique basement.

A homeowner in Mankato, MN, recently contacted us with a serious issue. Water was seeping into her finished basement, putting her home and belongings at risk. She had invested time and money into creating a comfortable living space downstairs, so when water intrusion began to threaten that space, she knew action needed to be taken immediately.

After a thorough inspection, we discovered that hydrostatic pressure around the home’s foundation was forcing water through the walls and floor joints. This is a common issue in Minnesota basements, especially after periods of heavy rain or snowmelt.

To solve the problem for good, our team installed a WaterGuard drainage system around the interior perimeter of the basement. This specialized system collects water at the base of the walls and channels it away before it can reach the finished surfaces. Next, we installed our CleanSpace vapor barrier on the walls to seal out moisture and help create a clean, dry environment. Finally, we added a powerful SuperSump sump pump system to discharge the collected water safely away from the foundation.

Now, the homeowner has peace of mind knowing her finished basement is protected from future water intrusion. She can confidently use the space for storage, entertainment, or relaxing—without worrying about moisture damage.

This homeowner in North Mankato, MN was dealing with a serious basement issue. Every time it rained heavily, water would leak into her basement through both the floor and the walls. Over time, the problem got worse. Large horizontal cracks had formed in the basement walls, and the walls were starting to bulge and bow inward due to hydrostatic pressure, which is a common issue in Minnesota when the soil around a home becomes overly saturated.

Not only was the basement wet and musty, but the structural integrity of the walls was also becoming a major concern. She wanted to make her basement safe, dry, and usable again, for storage, comfort, and peace of mind.

After reaching out to our team at Complete Basement Systems, we completed a full inspection and designed a comprehensive solution to solve the problem for good.

• WaterGuard Drainage System: We installed this patented interior drainage system around the perimeter of the basement floor. It collects water that leaks in through the floor or walls and directs it to a sump pump before it can enter the basement space.

• CleanSpace Wall Vapor Barrier: To further protect against moisture and humidity, we applied CleanSpace along the basement walls. This durable liner helps manage wall seepage while giving the space a clean, bright look.

• PowerBrace Wall Reinforcement System: To stop the inward movement of the cracked and bowing walls, we installed our PowerBrace system—galvanized steel I-beams that stabilize and strengthen the foundation walls and can be adjusted over time to help straighten them.

• New Basement Windows: We also upgraded the old, inefficient basement windows. New windows improve insulation, reduce drafts, and help prevent future leaks—especially important in a basement where water intrusion had already been an issue.
