Mankato, MN Dependable Basement Waterproofing & Crawl Space Repair

For years, a homeowner in South Central Minnesota has dealt with an all-too-common problem: water intrusion in the basement. Every heavy rain or snowmelt brought a new wave of stress. Puddles would form along the walls, musty smells would linger, and the homeowner had to give up on using the space for storage or anything else. It was frustrating, and the problem clearly wasn’t going to solve itself.

Eventually, they reached out to our team for help. During the inspection, we found signs of long-term water issues, damp walls, stained concrete, and visible damage at the base of the foundation. But we had a reliable solution ready.

To permanently address the problem, we installed our WaterGuard interior drainage system, designed to capture water before it ever reaches the basement floor. This system channels water safely to a sump pump, keeping the basement dry no matter the weather outside.

To further protect the space, we also installed CleanSpace vapor barrier along the walls. This bright white liner not only improves the appearance of the basement but also stops water vapor and humidity from seeping through the foundation. It helps prevent mold, musty odors, and further structural damage.

Now, the homeowner finally has a dry, usable basement they can rely on year-round. They’re no longer worried every time it rains, and the transformation has brought peace of mind and increased value to their home.

When a homeowner in Mankato, MN reached out to us, they were dealing with a frustrating and all-too-common issue, water in the basement. After every heavy rain or snowmelt, puddles would appear along the basement walls, leaving the space damp, musty, and unusable. They had dreams of turning their basement into a functional living area, but knew they needed to address the water issues first.

Our team came out for a free inspection and designed a custom waterproofing system to permanently solve the problem. We installed our WaterGuard interior drainage system, which collects water at the foundation’s edge and directs it to a reliable sump pump. To move that water safely out of the home, we installed a SuperSump system paired with an UltraSump battery backup, giving the homeowner peace of mind even during power outages.

To finish off the project, we lined the basement walls with CleanSpace vapor barrier, a durable, bright white liner that seals out moisture and gives the basement a cleaner, brighter appearance. Not only does CleanSpace help control humidity and prevent mold, but it also makes the space feel more finished and welcoming.

Now, this Mankato homeowner has a dry, protected basement they can confidently use and enjoy, no more worrying about wet walls, musty smells, or surprise puddles. Just a fresh start below ground!

When a Mankato, MN homeowner reached out to us, they were dealing with a handful of serious basement problems: water intrusion, bowing walls, and a space that had all the charm of an unfinished utility room. Between the damp floors, musty air, and unsettling cracks forming along the basement walls, they knew it was time to call in the pros, and that’s where we came in!

After a thorough inspection, we put together a plan to turn their basement into a dry, stable, and safe part of the home. This not only adds value to the home, but adds a large amount of usable space for the family to grow and enjoy!

First up: waterproofing. We installed our WaterGuard drainage system around the perimeter to collect and redirect any water that tried to sneak in. To manage that water, we paired it with our reliable SuperSump pump system, ensuring the basement stays dry even during heavy rains or melting snow.

To address the failing basement walls, we installed our PowerBrace wall bracing system. These heavy-duty steel I-beams are designed to stabilize bowing walls and can even help straighten them over time. Not only are they effective, but they also have a clean, finished look that fits right into a transformed space.

But the homeowner didn’t just want a dry, stable basement, they also wanted to use the space. So we added a beautiful RockWell egress window. Not only does it meet safety codes and provide an emergency exit, but it also lets in tons of natural light, instantly making the basement feel brighter and more livable.

Now, this Mankato basement is dry, safe, and full of potential. What started as a stressful, dark space is now a bright and secure area that the homeowner can use confidently for storage, living space, or whatever they dream up next.

After living in her Mankato, MN home for over 15 years, this homeowner had battled water issues in her basement and crawl space from day one. Every time it rained or snow melted, water would find its way in, damaging flooring, walls, and even appliances. Over time, she had to replace her furnace, washing machine, and rip out previous finishing work due to the persistent leaks.

Frustrated but determined, she finally decided it was time for a permanent solution. She contacted our team of basement and crawl space experts for a full evaluation. Her main concerns were protecting the integrity of her home’s structure and finding a fix that wouldn’t require constant maintenance.

After a thorough inspection, our System Design Specialist recommended a custom waterproofing and encapsulation system using CleanSpace, WaterGuard, and a SuperSump sump pump. CleanSpace would seal off the crawl space from moisture and humidity, WaterGuard would collect and channel water away from the foundation, and the SuperSump would reliably remove the water, even during heavy rains.

With her budget in place and confidence in our proven process, she moved forward with the project.

Now, her basement and crawl space are dry, protected, and ready for the long haul. This homeowner does not need to worry every time it rains. This transformation gave her not just peace of mind but also the chance to reclaim valuable space in her home.

This homeowner in Mankato, MN was dealing with a basement that had multiple problems, bowing walls caused by pressure from the surrounding soil, and persistent water leaks that were making the space damp and unusable.

Our System Design Specialist conducted a thorough inspection and recommended a system that will both stabilize the foundation and keep the basement dry. To address the structural concerns, we installed PowerBraces, a strong and adjustable wall reinforcement system that helps restore wall integrity over time. For the water issues, we installed our proven WaterGuard drainage system along the perimeter of the basement, paired with CleanSpace wall vapor barrier to prevent moisture from entering.

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.

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.
