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.

A homeowner in Madison Lake, MN reached out to us after years of dealing with major crawlspace concerns that were starting to affect the rest of their home. The floors above the crawlspace had begun to sag, moisture was building up underneath the house, and musty odors were becoming harder to ignore. They knew the issues weren’t going to resolve on their own, and they were ready for a permanent solution.

When our team inspected the crawlspace, we found structural weakening along with significant moisture intrusion. The homeowner needed both stability and protection, so we designed a solution that addressed every concern.

To restore the floor structure and eliminate the sagging, we installed SmartJacks, our galvanized steel support system. These adjustable supports immediately strengthened the beams above and provided a long-term, stable fix the homeowner can rely on.

Next, we encapsulated the entire crawlspace with CleanSpace, a durable vapor barrier designed to block moisture, reduce odors, and create a healthier environment throughout the home. This bright, clean liner transformed the crawlspace from a damp, dirty area into a sealed and controlled space.

To handle any water that might still find its way in, we added a SmartSump system. This sump pump is specifically designed for crawlspaces and ensures water is removed quickly and efficiently, keeping the area dry year-round.

By the time the project was completed, the Madison Lake homeowner had a crawlspace that was stable, dry, and protected for the long haul. Their home now sits on solid, dependable supports, and the improved air quality and moisture control have made a noticeable difference inside their living space. What was once a problem area is now a clean, secure part of their home they no longer have to worry about.

For many years, this North Mankato homeowner dealt with persistent water seepage in his basement. What started as a nuisance eventually became a major disruption, forcing him to remove stored belongings and furnishings to prevent further damage. After one too many cleanups, he knew it was time to stop relying on temporary fixes and invest in a permanent solution.

Because this wasn’t his first experience working with our team, the decision was easy. He wanted professionals he could trust to get it right the first time and deliver results that would last.

Our team designed and installed a complete waterproofing system tailored to his home. We started with WaterGuard, our proven interior drainage system, to capture water at the foundation and direct it safely away. We then installed CleanSpace along the basement walls to create a clean, dry barrier against moisture and humidity. To ensure reliable protection even during heavy storms or power outages, we finished the system with a SuperSump pump paired with an UltraSump battery backup.

The result? A basement that’s dry, protected, and ready to be used again, without worry. This project is a great example of how the right system, installed by a trusted team, can finally put an end to years of water problems for good.

When a homeowner in St. Peter, MN reached out to us, she was dealing with a wet basement and wanted a solution she could feel confident in. Water and moisture in a basement can quickly become more than just an inconvenience. It can affect how you use your home and contribute to an uncomfortable, damp environment.

Our team inspected the basement and designed a solution specifically for her home using CleanSpace, WaterGuard, a SuperSump, and a SaniDry Sedona dehumidifier.

The first step was addressing where water was getting into the basement.

WaterGuard was installed along the perimeter of the basement to collect water before it could reach the living space. The system directs that water to the SuperSump, which is designed to efficiently pump it out of the basement and away from the home.

We also installed CleanSpace to help protect the basement walls and create a cleaner, more moisture-resistant environment. Unlike a traditional basement wall finish, CleanSpace is designed to help keep moisture from passing through the walls and into the basement.

But keeping a basement dry isn't only about stopping visible water.

Basements can also have excess humidity, even when there isn't standing water. That's where the SaniDry Sedona comes in. This high-performance dehumidifier helps control basement humidity and creates a more comfortable environment while helping protect the space from moisture-related issues.

With the new waterproofing and humidity control system in place, this St. Peter homeowner now has a basement designed to stay drier, cleaner, and more comfortable.

And most importantly, she's now a happy customer!

A crawlspace shouldn’t smell damp, musty, or feel like a place you’d rather avoid. But for one homeowner in St. Peter, MN, that was exactly the problem.

He contacted Complete Basement Systems after noticing his dirt crawlspace was damp and musty. Like many homeowners in Minnesota, he was dealing with a space that was vulnerable to moisture, and leaving that moisture unchecked can create an environment that affects more than just the crawlspace itself.

Our team recommended the CleanSpace Encapsulation System to address the moisture concerns and transform the crawlspace into a cleaner, more controlled environment.

CleanSpace is designed to isolate the crawlspace from the damp earth and moisture below, helping keep unwanted humidity and moisture from making their way into the space.

For this homeowner, encapsulation meant no more looking at a damp, musty crawlspace and wondering what was happening underneath his home.

With Minnesota's changing seasons, wet weather, snow, and fluctuating temperatures, crawlspace moisture is a common concern for homeowners throughout Southern Minnesota.

If your crawlspace smells musty, feels damp, has visible moisture, or simply doesn't seem right, don't assume that's just the way crawlspaces are supposed to be.

We have the experience and specialized solutions to help homeowners identify what's causing crawlspace moisture and determine the right way to address it.
