Eagan, MN Egress Addition

Before

After

This homeowner in Eagan, MN had a small, outdated basement window that limited natural light and didn’t meet egress code requirements. Like many homeowners, they wanted to make their basement safer and more functional, whether for a future bedroom, added living space, or simply peace of mind knowing there’s a proper emergency exit. The existing window made the space feel dark, closed-in, and less usable overall.

We upgraded the space with a new RockWell egress window and a durable window well with a secure cover. This transformation not only brought in significantly more natural light but also created a safe, code-compliant escape route. The added window well cover helps keep out debris and water, ensuring long-term protection and low maintenance. Now, the basement feels brighter, more open, and ready for whatever the homeowner has planned next, adding both comfort and value to their home.

Saving an Old St Paul, MN Basement

Before

After

A St. Paul, MN homeowner reached out to us after years of dealing with constant water intrusion in their basement. Built in 1917, the home’s aging foundation allowed water to seep in regularly, creating a damp, musty environment that limited how the space could be used. Left unresolved, this ongoing intrusion risked further structural issues and continued damage to the home.

Our System Design Specialist evaluated the property and recommended a complete waterproofing system tailored to protect this historic home. The installation included a WaterGuard interior drainage system to efficiently collect and direct water, CleanSpace vapor barrier to seal walls and prevent moisture penetration, and a SuperSump sump pump with an UltraSump 4 battery backup to ensure reliable pumping even during power outages. To control humidity and air quality, we also installed a Sedona SaniDry dehumidifier. With these proven solutions in place, the basement is now dry, stable, and protected, ensuring this historic home remains safe and usable for the next 100 years.
